The 20L fuel tank capacity can ensure that the equipment can operate stably for a certain period of time and provide reliable power for floor construction. This power configuration enables the equipment to operate stably for a long time in large-area floor construction scenes such as large industrial plants and commercial plazas, avoiding the impact of insufficient power on the construction progress. (II) Leveling equipment ❶. **Vibration leveling equipment**: The vibration system of the equipment is driven by an electric motor with an excitation force of 2000N. After the concrete is poured, the equipment makes the concrete more compact through vibration, effectively eliminates the gaps and bubbles inside the concrete, and lays the foundation for creating a high-precision wear-resistant floor. In actual operation, this vibration leveling equipment can quickly and evenly process the concrete surface to ensure the flatness of subsequent construction. ❷. **Paving and leveling equipment**: It adopts hydraulic screw conveying paving mode with a leveling width of 2.5m (8.20ft).

In the field of modern concrete construction, concrete laser leveling machine has become an indispensable equipment for many large-scale engineering construction with its advantages of high precision and high efficiency. Among them, the laser transmitter is the core component, and its stable and accurate performance is directly related to the construction effect of the leveling head. So, does the laser transmitter need to be calibrated regularly? The answer is yes. Necessity of laser transmitter calibration Ensure construction accuracy: The laser transmitter provides accurate elevation benchmarks for Beton – Laser – Nivelliermaschine by emitting stable laser beams. During the construction process, if the laser transmitter deviates, the leveling machine will operate based on the wrong benchmark, resulting in the ground flatness and levelness after concrete pouring failing to meet the design requirements. For example, in large shopping malls, industrial plants and other projects with extremely high requirements for ground flatness, even a slight deviation may affect subsequent decoration, equipment installation and other processes, increase rework costs, and delay construction period. Adapt to environmental changes: The construction site environment is complex and changeable, and factors such as temperature, humidity, and vibration will affect the performance of the laser transmitter. Working in a high temperature environment for a long time, the optical components inside the laser transmitter may expand and contract due to heat, resulting in deviations in the emission angle of the laser beam; and frequent vibrations at the construction site may also loosen the internal components and affect the emission accuracy. Regular calibration can timely detect and correct these deviations caused by environmental factors, ensuring that the laser transmitter is always in the best working condition. Extend the service life of the equipment: When the working state of the laser transmitter is inaccurate, the leveling machine may over-adjust in order to achieve the set elevation, which will increase the wear of other parts of the equipment, such as the motor and hydraulic system. Regular calibration can ensure the normal operation of the laser transmitter, enable the various components of the Macchina livellatrice laser per calcestruzzo to operate in coordination, reduce unnecessary wear, thereby extending the overall service life of the equipment and reducing equipment maintenance costs. Determination of calibration cycle The calibration cycle of the laser transmitter is not fixed and needs to be determined by combining multiple factors. Frequency of use: For frequently used concrete laser leveling machines, such as equipment that operates continuously on large construction sites, it is recommended to calibrate once every 1-3 months. Because frequent use will cause the laser transmitter to accumulate errors faster, shortening the calibration cycle will help to find problems in time and ensure construction accuracy. Construction environment: If the construction environment is harsh, such as high temperature, high humidity, strong vibration or dusty environment, the calibration cycle should be shortened appropriately, and calibration can be considered once a month. Extreme environments have a greater impact on laser transmitters, and more frequent calibration can ensure that they can still work stably in complex environments. Equipment accuracy requirements: For engineering projects with extremely high requirements for ground flatness, such as high-precision electronic factories and airport runways, in order to ensure construction quality, it may be necessary to calibrate once every certain amount of work completed according to specific project requirements, or even perform a simple calibration check before construction every day. Calibration process and method Professional operation: Calibration of laser transmitters requires professional technicians to operate. They should have rich knowledge and calibration experience of laser measurement equipment, and be familiar with the working principle and performance parameters of Extendedoras de hormigón. Use of standard instruments: During the calibration process, high-precision standard measuring instruments, such as laser calibrators calibrated by authoritative institutions, are required. These standard instruments can provide accurate benchmarks for comparing and adjusting various parameters of the laser transmitter. Specific calibration steps: First, install the laser transmitter on the calibration table to ensure that it is firmly installed and in the correct position. Then, use the laser calibrator to emit a standard laser beam and compare it with the laser beam emitted by the laser transmitter. By adjusting the optical components and circuit parameters inside the laser transmitter, the deviation of the laser beams of both in the horizontal and vertical directions is controlled within the specified range. During the calibration process, the parameters such as the emission angle, spot size, and intensity of the laser beam need to be accurately measured and adjusted until the calibration standard is reached. After the calibration is completed, the calibration data needs to be recorded in detail, including the calibration time, calibration personnel, and parameter comparison before and after calibration, etc., for subsequent query and traceability. Regularly calibrating the laser transmitter of the concrete laser leveling machine is a key measure to ensure construction quality, adapt to environmental changes, and extend the service life of the equipment. Construction companies should attach great importance to the calibration of laser transmitters, reasonably determine the calibration cycle according to actual conditions, and strictly follow the calibration process and methods to ensure that the concrete laser leveling machine is always put into construction in the best condition, providing a solid guarantee for the smooth development of various engineering projects.

One-time forming construction method of large-area ultra-flat wear-resistant floor laser leveling machine 1. Introduction At the moment when the construction field is constantly innovating, the pursuit of flatness, strength and construction efficiency in large-area floor construction has reached a new height. Traditional construction methods are difficult to accurately control flatness when dealing with large-scale ground operations, and the construction period is long. The use of concrete laser leveling machine Beton – Laser – Nivelliermaschine to implement one-time forming construction has become an effective solution to break through these bottlenecks and provide strong guarantees for creating high-quality ultra-flat wear-resistant floors. 2. Features of the method Excellent precision: With the help of advanced laser systems, Macchina livellatrice laser per calcestruzzo has extremely high control accuracy for ground elevation, and can control flatness deviation within a very small range, far exceeding traditional construction methods, and meeting the stringent requirements of high-standard ultra-flat floors. Efficient operation: The equipment has a leading degree of automation, and a large area of ​​ground leveling can be completed in a single operation. Compared with traditional manual leveling, the construction period is greatly shortened and the construction efficiency is greatly improved. Material optimization: With precise elevation control, it can effectively avoid the situation of too much or too little concrete laying, reduce material waste and construction costs. Performance enhancement: Uniform vibration during the leveling process makes the internal structure of the concrete more compact and uniform, significantly enhances the strength and wear resistance of the ground, and extends the service life of the ground. 3. Scope of application This method is widely used in various large-area places with high requirements for ground flatness and wear resistance, such as industrial plants that need to withstand the operation of heavy equipment; logistics warehouses, where frequent cargo handling causes great damage to the ground; large shopping malls, where there is a large flow of people and the ground needs to be beautiful; parking lots, where vehicles frequently enter and exit and test the durability of the ground, etc. 4. Process principle The core of Extendedoras de hormigón lies in the collaborative work of high-precision laser transmitters and receivers. The laser transmitter emits a stable horizontal laser beam, just like building a precise reference plane in the air. The laser receiver is installed on the leveling machine frame to capture the laser signal in real time and quickly transmit it to the control system. The control system automatically and accurately adjusts the height of the screed blade according to the received signal to ensure accurate leveling of the concrete surface during the process. At the same time, the vibrating device equipped with the screed works synchronously to fully vibrate the concrete, ensure its density, and lay the foundation for high-quality ground. 5. Construction process and key points of operation (I) Construction process Base treatment → measurement and layout → installation of formwork → concrete pouring → laser leveling machine leveling → surface treatment (smoothing, spreading wear-resistant materials, etc.) → maintenance (II) Key points of operation Base treatment Thoroughly remove debris, dust, oil and other pollutants on the surface of the base to ensure that the surface of the base is clean and flat, providing a good foundation for subsequent construction. Use compaction machinery to compact the base. For weak foundations, effective measures such as replacement and reinforcement piles are required to improve the bearing capacity of the base and prevent later ground settlement. Measurement and layout Use precision measuring instruments such as total stations to accurately measure and lay out the elevation control lines and construction boundaries of the floor according to the requirements of the design drawings. Set firm control points at a certain distance (usually 3-5 meters) on the base. These control points serve as key references for the initial positioning and calibration of the laser leveling machine to ensure the accuracy of the equipment's running trajectory and elevation control. Install the formwork Install the formwork strictly according to the measured layout position. The formwork should be made of materials with high strength and good rigidity, such as high-quality steel formwork or reinforced wooden formwork. Use a level to accurately adjust the elevation of the top surface of the formwork so that it is completely consistent with the design elevation. The joints of the formwork should be tight, and sealing strips or tapes can be used to seal to prevent leakage during concrete pouring and affect the quality of the ground. Concrete pouring Preferably use commercial concrete, and its mix ratio needs to be professionally optimized according to factors such as engineering design strength, durability, and construction environment to ensure that the concrete performance meets the construction requirements. Concrete is efficiently transported to the construction area through equipment such as concrete pump trucks or mixer trucks. Pour in layers and sections from one end to the other. The pouring thickness should be 2-3 cm higher than the design elevation, and space for leveling should be reserved. During the pouring process, use an inserted vibrator or a flat vibrator to vibrate the concrete in time. The vibration points should be evenly distributed to avoid leakage or over-vibration and ensure the density of the concrete. Laser leveling machine leveling After the concrete pouring is completed, the laser leveling machine should be driven into the construction area as soon as possible to avoid the initial setting of the concrete affecting the leveling effect. Start the laser transmitter and laser leveling machine in turn, calibrate and debug the equipment comprehensively, and check whether the laser signal reception, scraper lifting control, and vibration device operation are normal. The operator sets a reasonable leveling machine route and speed according to the shape and area of ​​the construction site. The general speed is controlled at 1-3 meters per minute. During the leveling machine's movement, pay close attention to the equipment's operating status and the concrete surface. If local unevenness, depressions or convexities are found, stop the machine immediately and use manual filling or shoveling to repair. Surface treatment For ordinary floors, use a trowel machine for mechanical troweling after the initial setting of the concrete and before the final setting. The trowel machine operates in a horizontal and vertical cross-pattern, and generally needs to be troweled 3-5 times until the ground surface is flat, smooth, and free of smear marks. For wear-resistant floors, when the concrete is initially set, the wear-resistant materials (such as metal aggregates and non-metallic aggregate wear-resistant materials) selected according to the design requirements will be evenly spread on the concrete surface, and the spreading amount will be determined according to the material description and design requirements. After spreading, use a trowel to smooth the surface so that the wear-resistant materials and concrete are fully integrated to form a solid and wear-resistant floor surface. Maintenance After the ground construction is completed, maintenance work should be carried out immediately. Sprinkling maintenance can be used. The number of sprinkling times per day is determined according to the temperature and humidity, generally not less than 3-5 times, to keep the ground moist; plastic film can also be covered to prevent water evaporation and maintain the internal humidity of the concrete; curing agent can also be sprayed to form a protective film on the ground to achieve the maintenance effect. The curing time is usually not less than 7-14 days, and the specific duration is determined according to the concrete strength growth and relevant specifications. During the maintenance period, it is strictly forbidden for people and vehicles to walk or roll on the ground to prevent damage to the ground strength growth process and ensure that the final strength of the ground meets the design requirements. 6. Materials and Equipment (I) Materials Concrete: must strictly meet the design strength grade requirements, have good workability, fluidity and durability, and ensure easy pouring and vibration during construction. Wear-resistant materials: accurately select wear-resistant materials according to the actual needs of the project and design standards. Metal aggregate wear-resistant materials have the characteristics of high hardness and high strength; non-metal aggregate wear-resistant materials have excellent performance in impact resistance and anti-static, and can be selected as needed. Formwork materials: steel formwork has the advantages of high strength and high turnover; wooden formwork has certain advantages in shape adaptability and splicing flexibility. Appropriate formwork materials can be selected according to construction conditions and cost considerations, but their strength and rigidity must meet construction requirements. (II) Equipment Extendedoras de hormigón: According to the size of the construction site, the complexity of the shape and the ground design requirements, reasonably select equipment models with power, leveling width and accuracy. Laser transmitter and receiver: Closely matched with laser leveling machine, laser transmitter emits stable and accurate laser beam, receiver accurately captures signal, the two work together to ensure high precision of elevation control, and their performance directly affects the quality of ground leveling. Concrete delivery equipment: Concrete pump truck has strong mobility and is suitable for concrete delivery in different site conditions; mixer truck can ensure the uniformity and working performance of concrete during transportation, and can be reasonably used according to the construction site conditions. Trowel machine: Divided into hand-held type and driving type, selected according to the ground area and construction efficiency requirements. Its high-speed rotating trowel compacts and smoothes the ground to make the ground flat and smooth. Measuring instruments: Total station is used for large-area high-precision measurement and layout; level can accurately measure elevation; theodolite assists in determining angles and verticality. These measuring instruments jointly provide accurate data support for positioning and elevation control during construction. 7. Quality control Quality management system construction: Set up a professional quality management team to clarify the specific responsibilities of each member in the stages of construction preparation, construction process and quality acceptance. Formulate a detailed quality management system and set clear and quantifiable quality goals, such as controlling the ground flatness deviation within ±2 mm. Raw material quality control: Each batch of raw materials such as concrete and wear-resistant materials entering the site shall be inspected and tested strictly in accordance with relevant standards. Concrete needs to be tested for slump, compressive strength and other indicators; wear-resistant materials need to be tested for their wear resistance, hardness and other properties to ensure that the quality of raw materials fully meets the design and specification requirements and ensure the quality of the project from the source. Construction process quality supervision: Arrange professional quality management personnel to supervise the entire construction process and strictly follow the established construction process and operation points. Focus on monitoring whether the laser operation is standardized, including equipment calibration, travel speed and route control; whether the concrete pouring and vibration meet the requirements, such as pouring sequence, vibration time and depth, etc.; the timing of polishing in the surface treatment process, the uniformity of wear-resistant material spreading, etc., and timely rectification when problems are found. Quality acceptance: After the construction is completed, the ground is comprehensively inspected in accordance with the current relevant national specifications and standards. Use professional measuring tools to detect the flatness and elevation deviation of the ground; use equipment such as rebound testers to detect the ground strength; and use wear resistance testers to test the wear resistance of wear-resistant floors. Only after all indicators meet the requirements after testing can the project quality be determined to be qualified. 8. Safety measures Building a safety management system: Develop a complete safety management system covering all aspects such as construction site safety protection, equipment operation specifications, and personnel safety training. Clarify the safety responsibilities of personnel in various positions, and implement safety responsibilities at all levels from project managers to front-line construction personnel. Safety education and training: Regularly organize construction personnel to participate in safety education and training, including safety regulations, safety operating procedures, accident case analysis, etc. New employees must undergo three-level safety education and training and pass the assessment before they can take up their posts. Special types of work (such as electricians, welders, machine operators, etc.) must be certified to work, and continuously improve the safety awareness and operating skills of construction personnel. Safety protection at the construction site: Set up obvious safety warning signs at the entrance of the construction site and dangerous areas (such as deep foundation pits, high-altitude working areas, etc.). Set up protective railings and safety nets for high-altitude working surfaces; equip construction workers with qualified personal protective equipment such as safety helmets, safety belts, safety shoes, and supervise their correct wearing and use. Equipment safety management: Establish a regular inspection and maintenance system for construction equipment such as laser levelers and concrete conveying equipment, conduct equipment appearance inspections and performance tests before and after each use, and conduct regular comprehensive maintenance and repairs. During the operation of the equipment, operators must strictly abide by the operating procedures, and illegal operations are strictly prohibited to prevent safety accidents caused by equipment failures or improper operations. 9. Environmental protection measures Construction dust control: Harden the main roads in the construction site, and arrange special personnel to sprinkle water to reduce dust regularly. Sand, stone and other materials that are prone to dust are stored in closed silos, or covered with dustproof nets to reduce dust pollution. Construction noise control: Plan construction time reasonably to avoid high-noise operations during residents' rest time (such as 22:00 to 6:00 the next day). Take noise reduction measures for high-noise equipment such as concrete pumps and vibrators, such as installing silencers and setting up soundproof covers, to reduce the impact of construction noise on the surrounding environment. Waste treatment: Set up classified trash cans and waste storage sites at the construction site to classify and collect construction waste and domestic waste generated during the construction process. Recyclable waste (such as scrap steel, waste wood, etc.) is recycled and reused; non-recyclable waste is transported to designated locations for proper disposal in accordance with the requirements of local environmental protection departments to prevent environmental pollution. 10.

Environmental benefits: By implementing a series of environmental protection measures, such as dust control, noise control, and reasonable disposal of waste, the pollution of the surrounding environment during the construction process is reduced, which conforms to the concept of green environmental protection and sustainable development, and produces positive environmental benefits.

To check whether the laser receiver of the concrete laser leveling machine (Beton – Laser – Nivelliermaschine, Macchina livellatrice laser per calcestruzzo, Extendedoras de hormigón, เครื่องปรับระดับคอนกรีตด้วยเลเซอร์, Máy cán sàn bê tông bằng Laser) is working properly, you can follow the steps below 1. Preliminary inspection – Appearance inspection: Carefully check whether the shell of the laser receiver is damaged or cracked, and whether the connecting line is damaged or loose. If these problems exist, it may cause signal transmission failure, and the damaged parts need to be repaired or replaced in time. – Power supply check: Make sure the receiver is connected to the power supply and the power indicator is on normally. If the indicator light is off, check whether the power socket and power cord are normal, and whether the power switch of the receiver is turned on. 2. Signal reception check – Observe the signal indicator: Most laser receivers have a signal indicator. When receiving a laser signal, the indicator will have a corresponding display, such as lighting up or flashing. When the laser transmitter is turned on, observe the signal indicator of the receiver. If the indicator does not respond, the receiver may not receive the signal and further investigation is required. – Manual blocking test: When the laser transmitter is emitting laser normally, use an opaque object to temporarily block the receiving window of the laser receiver and observe the changes in the signal indicator. If the indicator light goes out or changes state when blocked, it means that the receiver responds to the laser signal, and the initial judgment is that the receiving function is normal; if the indicator light does not change, the receiver may have a fault. 3. Function test – Slope control function test: If the concrete laser leveler has a slope control function, set different slope parameters and observe whether the laser receiver can accurately control the leveler to perform construction according to the set slope. If the leveler cannot work according to the set slope, there may be a problem with the slope control function of the laser receiver. – Flatness detection function test: Run the concrete laser leveler on a test platform or ground with known flatness, let the laser receiver work and record the flatness data it measures. Compare the data with the actual flatness to check whether the measurement result is within the allowable error range. If the deviation is large, it means that the flatness detection function of the laser receiver may be inaccurate and needs to be calibrated or repaired. 4. Receiving range and accuracy test – Different position test: In the working area of ​​the concrete laser leveler, select multiple different positions, including positions close to, far from, and at different angles from the laser transmitter, and observe whether the laser receiver can receive signals normally and work accurately at these positions. If the signal is lost or works abnormally at certain positions, it means that there is a problem with the receiver's receiving range or angle. – Accuracy calibration test: Use professional measuring tools, such as high-precision levels, to compare with the measurement results of the laser receiver. Perform measurement comparisons at multiple different positions to check whether the measurement accuracy of the laser receiver meets the equipment requirements. If the accuracy deviation is found to exceed the allowable range, the laser receiver needs to be calibrated and debugged. 5. Software and parameter check Enter the setting interface of the laser receiver and check whether the software settings and parameters are correct. Make sure that the parameters such as working mode, laser wavelength, sensitivity, etc. match the laser transmitter and the entire leveling machine system. Incorrect parameter settings may cause the receiver to work abnormally, and it is necessary to set it correctly according to the equipment manual. 6. Professional equipment detection If conditions permit, professional optical detection equipment such as optical power meter, laser interferometer, etc. can be used to perform more accurate detection of the laser receiver. These devices can measure the laser power, wavelength stability, beam quality and other parameters received by the receiver, and compare them with the technical specifications of the receiver to accurately determine whether it is working properly. 7. Comparison and replacement If there are multiple concrete laser leveling machines of the same model, the suspected problematic laser receiver can be interchanged with the receivers on other machines that are working properly. Then observe the working conditions of the two machines. If the original normal machine has the same problem as before, and the original problematic machine returns to normal, it can be determined that the laser receiver itself is faulty and needs to be repaired or replaced.

The following are the precautions for daily maintenance and care of the hydraulic system of the concrete laser leveling machine ✨Oil management: – Check the hydraulic oil level regularly, park the เครื่องปรับระดับคอนกรีตด้วยเลเซอร์ on a level surface, turn off the engine and check to ensure that the oil level is within the normal scale range. If the oil level is found to be too low, add hydraulic oil that meets the equipment requirements in time. Different models of concrete laser leveling machines, such as vanse concrete laser leveling machine or mini concrete paver leveling machine, may have different requirements for hydraulic oil, and must be selected strictly according to the instructions. – Pay attention to the quality of the oil. Hydraulic oil will age and deteriorate after long-term use. If the oil is found to be black, has a pungent smell, is turbid or has precipitation, it should be replaced immediately even if the specified replacement cycle has not been reached. When replacing, drain the old oil thoroughly, clean the oil tank and filter, and then add new oil. At the same time, pay attention to the equipment with higher vanse laser leveling price, and use high-quality hydraulic oil to ensure the performance and life of the hydraulic system. ✨Filter maintenance: – The filter in the hydraulic system plays a key role and should be replaced regularly. Generally speaking, the filter needs to be replaced every certain number of working hours or every few months. The specific interval can be referred to the equipment manual. For places with harsh working environment and large dust, the replacement cycle should be appropriately shortened to ensure the cleanliness of the hydraulic oil and protect the precision parts of the hydraulic system. – When replacing the filter, carefully check whether there are impurities such as metal particles and fibers on the filter. If a large amount of impurities are found, it may mean that there are worn parts inside the hydraulic system, which requires further inspection and repair to avoid the expansion of the fault and affect the normal use of the เครื่องปรับระดับคอนกรีตด้วยเลเซอร์ or Extendedoras de hormigón. ✨System component inspection: – Check the working status of the hydraulic pump and hydraulic motor, listen to whether the running sound is normal, and whether there is abnormal vibration and noise. Observe whether its working pressure is stable and whether it is within the specified range. If the pressure is unstable or there is an abnormal sound, it may be due to wear of the internal parts of the pump or motor, damage to the seal, etc., which needs to be repaired or replaced in time to ensure the stable power output of the Máy cán sàn bê tông bằng Laser hydraulic system. – Check whether there is oil leakage in the oil pipe and joints, and whether the oil pipe is damaged, aged, cracked, etc. If the oil pipe is found to be damaged, it should be replaced in time; loose joints should be tightened in time to prevent oil leakage from causing the pressure of the hydraulic system to drop and affect the normal operation of the equipment. At the same time, keep the surface of the system clean, clean up oil and dust in time to prevent them from entering the hydraulic system. In short, doing a good job of daily maintenance and maintenance of the hydraulic system of the concrete laser leveling machine can effectively extend the service life of the equipment, improve work efficiency, reduce maintenance costs, and ensure that the equipment can operate stably and reliably under various working conditions.

For example, the area of ​​each compartment in this project is set at 1,920 square meters, while the area of ​​each compartment should be 400 square meters under the premise of ensuring quality for manual scraping. – Reduce the cost of later maintenance: Due to the good integrity of the ground, the problems of ground cracking and hollowing caused by construction joints are reduced, and the cost of later maintenance is reduced. ⛳ Realize real-time monitoring – Automatically monitor the operating status: The laser leveler can realize automatic monitoring of the operating status, prevent problems that occur in the project in real time and solve them in time, and ensure the safety, reliability and stability of the construction process. – Timely adjust construction parameters: By real-time monitoring of the flatness and elevation of the ground, construction personnel can adjust the working status of the laser leveler in time to ensure that the construction quality meets the design requirements. ⛳ Improve construction safety – Reduce operating risks for personnel: The use of laser leveling machines reduces the risks of construction personnel working at heights and operating heavy machinery, and improves construction safety. – Standardize construction process: The construction process of the laser leveling machine is relatively standardized, reducing safety accidents caused by improper human operation. ⛳

The construction process and requirements of laser leveling concrete wear-resistant floor Definition Laser leveling concrete wear-resistant floor refers to the use of laser leveling machines to perform high-precision and rapid leveling operations on concrete, thereby obtaining a concrete wear-resistant floor that meets high standards in terms of flatness, levelness, density and strength. Working principle of concrete laser leveling machine The concrete laser leveling machine uses laser as the reference plane, and emits rotating laser through the laser transmitter. The laser signal is captured by the laser receiver on the leveling machine. The received signal is deeply analyzed by the laser measurement and control system, and any deviation will be accurately identified and fed back to the highly sensitive computer control system on the leveling machine. Based on this feedback information, the leveling machine will intelligently adjust the height of the scraper or leveling head to ensure the accuracy of the leveling operation. At the same time, the hydraulically driven vibration motor drives the vibration plate to vibrate the concrete to further compact the ground. Concrete laser leveling machine wear-resistant floor construction process (1) Construction preparation Material preparation: Ensure the quality of concrete materials. Polycondensate high-efficiency water reducer can be added to reduce the risk of cracking. At the same time, prepare the required wear-resistant aggregates, interface agents and other materials. Equipment preparation: Transport and place laser leveling machines, trowels, trimmers, vacuum cleaners and other equipment to the designated location on site, and perform maintenance work to ensure that the equipment is in good standby condition. Base treatment: Mill the base to increase the adhesion between the leveling layer concrete and the base. Clean the surface of the concrete base plate and use a high-pressure water gun to thoroughly rinse the floor surface. Sweep mortar or apply special interface agent as needed. (2) Formwork setting and steel bar laying Formwork setting: Set the formwork according to the design requirements, ensure that the formwork support is on the same horizontal line as the elevation, and use a special formwork frame to set it at an inclined angle to facilitate subsequent construction. Rebar laying: Adding steel bars to concrete can effectively increase the tensile strength of concrete and prevent cracking. The steel mesh should be placed 20mm~30mm away from the floor surface, which not only increases the tensile strength of concrete but also protects the surface from cracks. (3) Concrete paving and laser leveling Concrete paving: The mixed concrete is pumped and spread on the crushed stone base. The paving speed should be appropriate, and manual leveling should be assisted quickly. Ensure that the concrete construction thickness meets the design requirements. Laser leveling: Use a laser transmitter to determine the height of the concrete paving construction, and use a laser leveling machine to perform leveling operations. During the leveling process, one person should be responsible for moving the laser leveling machine, and two people should be responsible for the front-end auxiliary leveling to ensure that the concrete surface remains at the designed height (4) Initial grinding and slurry breaking and throwing wear-resistant aggregates Initial grinding and slurry breaking: When the concrete is initially set, use a single-disc and double-disc trowel to repeatedly rub and level the concrete slurry. The best time is when there are no clear footprints left by people on the concrete. Spreading wear-resistant aggregate: Spread the specified amount of wear-resistant material evenly on the surface of the concrete just after the slurry is broken. Special materials can be considered as specific conditions and spread more than twice. After each spreading, use a trowel to grind and compact the aggregate. Finishing and maintenance Finishing operation: Depending on the degree of hardening of the concrete, perform at least three trowel operations without a disc. The speed and angle of the trowel should be adjusted according to the degree of hardening of the concrete. The corners can be manually scraped. Maintenance: After the construction is completed, it takes more than 28 days to maintain. Sprinkle water for maintenance and lay soil cloth to reduce water evaporation and keep the wear-resistant floor after construction in water. (5) Cutting expansion joints and subsequent treatment Cutting expansion joints: After the concrete has been sprinkled with water for a certain period of time (such as 24 hours), cut the expansion joints according to the design requirements.

The daily maintenance and care of concrete laser leveling machines covers many aspects. Here are some precautions Electrical system – Cleaning and inspection: Regularly clean the dust in the electrical control cabinet to prevent dust accumulation from affecting heat dissipation and causing circuit failures. Check whether the connections of each electrical component are loose, whether the wires are damaged or aged, and replace or repair them in time if there are any problems. – Battery maintenance: For laser leveling machines equipped with batteries, charge and maintain them according to the battery manual. Check the electrolyte level of the battery regularly, and add distilled water in time if it is insufficient. When not in use for a long time, the battery should be charged and discharged at regular intervals to prevent the battery plates from vulcanizing. – Sensor inspection: Laser receivers, inclination sensors, etc. are key components of laser leveling machines, and their sensitivity and accuracy should be checked regularly. Avoid collision and damage to the sensor. If there are stains, clean them in time to ensure that they can receive and transmit signals normally. Mechanical parts – Lubrication and maintenance: Lubricate each lubrication point regularly according to the requirements of the equipment's manual. Generally speaking, chains, gears, drive shafts and other parts need to be lubricated at least once a week, using appropriate lubricants to ensure lubrication effect. – Tighten connections: Check whether the connecting bolts of each component are loose, especially the connection parts of key components such as scrapers, leveling beams, and travel wheels. During the operation of the equipment, vibration may cause the bolts to loosen. Regular tightening can prevent the parts from falling off and ensure the stability and safety of the equipment. – Wear inspection: Pay attention to the wear of parts such as scrapers and leveling beams that are in direct contact with concrete. Severe wear of the scraper will affect the leveling effect, and deformation or wear of the leveling beam will cause flatness deviation. Repair or replace in time according to the degree of wear. Hydraulic system – Oil inspection: Regularly check the oil level and oil quality of the hydraulic oil. The oil level should be kept within the specified range. If it is insufficient, add hydraulic oil of the same model in time. Observe whether the oil is turbid, has impurities or discoloration. If there is any abnormality, the hydraulic oil should be replaced in time to prevent the hydraulic system from malfunctioning. – Filter replacement: The filter element in the hydraulic system plays an important role in filtering impurities. The filter element should be replaced according to the specified time or working hours. Generally, it should be replaced every 500-1000 working hours, or in advance according to the oil quality, to ensure the cleanliness of the hydraulic oil. – Pipeline inspection: Check whether the hydraulic pipeline has leakage or damage. If there is a leak, the leak point should be found in time, and the seal should be replaced or the pipeline should be repaired. Pipeline damage will cause hydraulic oil leakage, affecting system pressure and normal operation, and may also cause environmental pollution. Laser system – Transmitter maintenance: The laser transmitter is the core component of the laser leveling machine. It should be kept clean to prevent dust, water vapor, etc. from entering the transmitter. Regularly check the laser beam intensity and accuracy of the transmitter, and calibrate it in time if there is any deviation. – Receiver cleaning: The surface of the laser receiver should be kept clean to ensure that the laser signal can be received clearly. Avoid interference from direct sunlight, strong magnetic fields, etc. to the receiver, and the installation position should be firm to prevent vibration and displacement. – Signal transmission check: Check whether the signal transmission between the laser transmitter and the receiver is normal, and whether there is any signal interruption or instability. If there is a problem, check whether the signal transmission line and interface are loose, or whether there are any obstructions, etc. Whole machine cleaning – Surface cleaning: After each use, the concrete residue, dust and oil stains on the surface of the equipment should be cleaned in time. You can use a high-pressure water gun or a special cleaning agent for cleaning, but be careful to avoid water entering the electrical system and hydraulic system. – Internal cleaning: Open the protective cover of the equipment regularly to clean the internal debris and dust. Especially in the engine compartment, electrical control cabinet and other parts, ensure good ventilation and no accumulation of debris to prevent malfunctions due to poor heat dissipation.

Unstable installation of the laser transmitter of the concrete laser leveling machine will cause problems in many aspects such as construction accuracy, equipment performance, construction efficiency and safety, as follows: Impact on construction accuracy – Flatness deviation: If the laser transmitter is installed unstably, the baseline of the laser beam it emits will fluctuate or deviate. The leveling machine relies on laser signals to control the height and levelness of the scraper or leveling beam. Inaccurate baselines will cause height differences on the concrete surface at different locations, causing the flatness to exceed the allowable error range, affecting the overall quality and performance of the ground. – Slope error: For concrete construction with slope requirements, such as parking lots and roads, unstable installation of the laser transmitter will cause deviations in slope control. It may lead to poor drainage, water accumulation in low-lying areas, affecting the use function, and even causing long-term damage to the concrete structure. Reduce equipment performance – Increase mechanical wear: Due to the unstable installation of the laser transmitter, the leveling machine will frequently make unnecessary adjustments and corrections during operation, which will cause the mechanical parts of the equipment to bear additional stress and impact. Long-term operation will accelerate the wear of mechanical parts, such as scrapers, leveling beams, transmission devices, etc., reduce the service life of the equipment, and increase maintenance costs and downtime. – Affect the life of electronic components: Unstable installation may cause vibration and impact of the electronic components inside the laser transmitter, resulting in loose connections, solder joints falling off or circuit failures. At the same time, unstable working conditions can cause problems such as overheating of electronic components, shorten the service life of electronic components, and affect the overall performance and reliability of the laser transmitter. Lead to reduced construction efficiency – Increase construction time: The construction accuracy problems caused by unstable installation of the laser transmitter require construction workers to spend more time on manual repairs and leveling. In addition, the decline in equipment performance may also cause failures and require downtime for maintenance, which will extend the overall construction time and affect the progress of the project. – Reduce construction continuity: Various problems caused by unstable installation will lead to frequent pauses and adjustments during the construction process, destroying the continuity and smoothness of the construction. This will not only affect the work efficiency and enthusiasm of construction workers, but may also have an adverse effect on the pouring quality of concrete, such as cold joints and loose concrete bonding. Safety hazards – Risk of equipment tipping: Unstable installation of the laser transmitter may cause it to shake or tip during operation, posing a safety threat to surrounding construction personnel and equipment. Especially when working at heights or when there are dense personnel and equipment on the construction site, the tipping of the transmitter may cause serious safety accidents. – Electrical safety issues: Unstable installation may loosen the power cord, signal line and other connections of the laser transmitter, leading to electrical safety issues such as poor contact and short circuit. This may not only damage the equipment, but also cause safety accidents such as fire, threatening the safety of personnel and property on the construction site.

How to ensure the laser transmitter of the concrete laser leveling machine is installed stably? It is very important to ensure that the laser transmitter of the concrete laser leveler is installed stably. Here are the specific methods: Pre-installation preparation – Select a suitable location: According to the shape, size and obstacle distribution of the construction site, choose an open, flat location that can fully cover the construction area to install the laser transmitter. Generally speaking, it can be placed near the center of the site or at the edge of the site where the terrain is higher, and avoid placing it in places that are susceptible to vibration and collision. – Clean the installation surface: Use cleaning tools such as brooms and rags to thoroughly remove dust, debris, oil and loose particles on the surface of the installation location to ensure that the surface is clean and flat, providing a good foundation for subsequent installation. – Check the appearance of the transmitter: Carefully check whether the laser transmitter has any external damage, such as cracked or deformed shell, and whether the lens has scratches, stains, looseness, etc., to ensure that the laser transmitter itself has no quality problems and damage, so as to avoid affecting its normal operation and installation stability. Installation process operation – Use the level adjustment device: When installing, use the level adjustment foot or level meter that comes with the laser transmitter. By adjusting the height of the level adjustment foot, the level bubble of the laser transmitter is located in the center position to ensure that the transmitter is in a horizontal state. For some high-precision laser transmitters, a high-precision electronic level may also be required for auxiliary calibration. – Fix with a fastening device: After placing the laser transmitter in the selected position, use the matching bolts, nuts, washers and other fastening devices to firmly fix it on the mounting bracket or foundation. When tightening the bolts, operate according to the specified torque value to ensure that the tightening force of each bolt is uniform to prevent the transmitter from tilting or loosening due to uneven force. – Perform angle calibration: According to the construction requirements, use the angle adjustment mechanism on the transmitter to accurately adjust the angle of the laser emission so that it maintains the correct angle relationship with the construction plane or reference plane. During the calibration process, angle measurement tools such as theodolites and total stations can be used for auxiliary measurement to ensure that the angle error is within the allowable range. Post-installation inspection and maintenance – Inspect installation stability: After installation, gently shake the laser transmitter to check for looseness or shaking. At the same time, observe whether the horizontal state and angle of the transmitter have changed. If there is any abnormality, readjust and tighten it in time. – Regular maintenance and calibration: During the use of the concrete laser leveling machine, the laser transmitter should be inspected and maintained regularly. At regular intervals of working time or construction mileage, the transmitter's horizontality, angle, and accuracy of the laser beam should be calibrated and debugged to ensure that it always maintains a stable and accurate working state. – Set up protective measures: To prevent the laser transmitter from being disturbed and damaged by external factors, protective devices such as guardrails and protective covers can be set around it. The height and strength of the guardrail should be able to effectively prevent personnel and equipment from colliding with the transmitter, and the protective cover should be able to prevent rain, dust, and sun, providing a good working environment for the transmitter.
