  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. 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. 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. 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. Base treatment → measurement and layout → installation of formwork → concrete pouring → laser leveling machine leveling → surface treatment (smoothing, spreading wear-resistant materials, etc.) → maintenance 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. 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. 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. 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. 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. 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. 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.   Economic benefits: The one-time forming construction method of the laser leveling machine has greatly improved construction efficiency, shortened the construction period, and correspondingly reduced labor costs and equipment rental costs. Accurate leveling effectively reduces concrete waste and saves material costs. Comprehensive calculations can significantly improve the economic benefits of the project. Social benefits: The high-quality, ultra-flat, wear-resistant floor created by this method can effectively improve the performance and durability of the building, reduce the cost of later maintenance and renovation, provide the society with better building space, and create good social benefits. 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.  

With the addition of concrete laser leveling machines in the construction industry and road construction industries, there has been a qualitative leap in both quality and speed, and it has also saved a lot of costs for users. However, in the face of high-frequency use, users cannot ignore the cleaning of the equipment. This step must not be sloppy. Let's take a look at how to clean the leveling in a few steps! 1 The liquid crystal surface on the laser leveling machine body also needs to be cleaned. You can use organic resin or lens cleaning cloth to wipe off the dirt. If there is too much dirt, it can be removed with a lens cleaning solution. 2 After the laser leveling machine is constructed, there will be a lot of dust and mud. First of all, the dust on the laser leveling machine should be wiped clean, and the dirt and oil stains should be wiped clean with tissue paper or cotton cloth. 3   If the laser signal is lost during the construction of the laser leveling machine, the machine needs to be restarted, and the interval should be more than ten seconds.  4 If there are too many stains, you can use a soft cloth to soak in water diluted with a neutral detergent, wring it out and clean it. The best laser leveling machine manufacturers remind you not to use volatile oil, thinner, gasoline, etc. Chemical cleaning wipe.   The laser leveling machine uses a scraper to take away the raised concrete and initially level it to reach the elevation required by the design. The hydraulically driven vibrating motor vibrates at a frequency of 4000 times per minute, driving the entire vibrating plate to vibrate the concrete together. The leveling of the laser paver does not need to pull the control line, nor does it need the side formwork to control the ground elevation, but is controlled by the laser measurement and control system on the laser leveling machine in real time. As long as the laser transmitter is not disturbed, no matter where the laser leveling machine moves Wherever it is, it can be ensured that the overall elevation of the paved ground will not be affected. The concrete ground laser leveling machine is to spread the mixed concrete along the subgrade according to the given thickness, width and road type requirements, and then complete the construction of paving the concrete road surface through the operation procedures of vibrating, leveling and troweling. mechanical. The working device of the concrete floor laser leveling machine generally consists of a distributor, a scraper, a vibrator (including a vibrator and a vibrator), a leveling machine, a trowel and other devices. At the same time, it also requires the organic cooperation of the frame, walking mechanism, manipulation control system and other auxiliary mechanisms. Some models integrate all the devices into one, and some are divided into two or more independent stand-alone machines.
