How to use vibratory leveling to assist concrete laser leveling machine in small areas

In the field of modern floor construction, efficient and precise construction technology is the key to ensuring the quality and progress of the project. As an industry-leading concrete leveling solution, Vanse Concrete Laser Leveling Machine is designed for various floor construction scenarios, such as industrial plants, warehouses, parking lots, etc., providing unprecedented construction advantages. Its core lies in the use of advanced laser technology to achieve precise control of the flatness of the concrete surface and create a perfect floor project for users.   (I) Laser emission and reception The laser transmitter equipped with Vanse laser leveling machine can be installed on a stable reference point to emit a horizontal laser beam to the construction area to form an accurate plane reference. Whether it is a rotating or fixed laser transmitter, it can be flexibly selected according to the size and shape of the construction site to ensure that the horizontal accuracy can reach ±0.5mm/10m. It uses 635nm or 650nm visible red light wavelengths that are safe for human eyes, which is convenient for construction personnel to observe and calibrate. The power range is 5mW-10mW, which meets the signal strength requirements within the construction range. At the same time, the laser receiver on the leveler can receive laser signals in real time, providing accurate data for subsequent automatic control.   (II) Automatic control and feedback When the laser receiver detects that there is a deviation between the position of the leveler scraper and the laser plane, the advanced control system of the Vanse laser leveler begins to play a role. The system adopts PLC (programmable logic controller) or microcomputer control system, with automatic control, manual adjustment and fault diagnosis functions, and uses advanced PID (proportional-integral-differential) control algorithm to automatically adjust the height of the scraper according to the deviation signal. The scraper is driven up or down by the hydraulic system to keep the scraper on the laser plane at all times, thereby ensuring that the flatness error of the concrete surface is controlled within a very small range.   (I) Laser transmitter 1. Type: Two options are available: rotary and fixed to meet the needs of different construction sites. 2. Accuracy: The horizontal accuracy is as high as ±0.5mm/10m, ensuring that the emitted laser plane is highly accurate. 3. Laser wavelength: 635nm or 650nm visible red light is used, which is safe for human eyes and convenient for construction operation. 4. Power: 5mW – 10mW, to ensure the signal strength within the construction range.   (II) Laser leveling machine 1. Scraper system – Scraper material: The use of high-strength wear-resistant alloy materials, such as high-chromium alloy, greatly guarantees the wear resistance and service life of the scraper, reduces the replacement frequency, and reduces the cost of use. – Scraper length and width: Length 2 – 5m, width 0.5 – 2m, can cover a larger area of ​​concrete surface, improve construction efficiency. – Scraper adjustment range: The vertical adjustment range is 0 – 30cm, which is suitable for concrete construction of different thicknesses. 2. Walking system – Walking mode: Two walking modes are provided: crawler and wheeled. The crawler is suitable for complex terrain and soft ground, and the wheeled walking speed is faster. Users can freely choose according to the conditions of the construction site. – Travel speed: It can be adjusted within the range of 0 – 1.5m/s, and the operator can flexibly adjust it according to the slump of concrete and construction requirements. – Drive motor power: According to the weight of the whole machine and the travel resistance, the motor power is 5 – 20kW to ensure that the leveling machine can walk stably on the concrete. 3. Hydraulic system – Hydraulic pump type: A variable piston pump is selected, which can automatically adjust the output according to the system pressure and flow requirements, improve the efficiency of the hydraulic system, and reduce energy consumption. – Hydraulic cylinder parameters: The stroke and thrust of the scraper lifting cylinder meet the scraper adjustment requirements, and the working pressure is 10 – 20MPa. – Hydraulic oil cooling method: Air-cooled or water-cooled cooler to ensure that the hydraulic oil temperature is within the normal working range and prevent the oil temperature from being too high to affect the system performance. 4. Laser receiver and control system – Laser receiver accuracy: It can accurately detect the laser plane deviation of ±1mm, providing guarantee for high-precision leveling. – Control system type: It adopts advanced PLC or microcomputer control system with powerful functions. – Control algorithm: Equipped with advanced PID control algorithm, it can quickly and accurately adjust the scraper height to ensure leveling accuracy.   (I) Construction preparation 1. Site cleaning: Clear the debris, dust and obstacles in the construction site, check and repair the base layer, ensure that the base layer flatness error is within ±10mm, and lay a good foundation for subsequent construction. 2. Laser transmitter installation and calibration: According to the size and shape of the construction site, select a suitable installation location, use tools such as a level to accurately calibrate the Vanse laser transmitter to ensure that the laser plane meets the design requirements. 3. Material preparation: Prepare concrete raw materials that meet the design requirements, and check their quality and slump (generally controlled at 12-18cm).   (II) Concrete pouring and leveling 1. Concrete pouring: Pour the concrete evenly in the construction area. The pouring method can be divided into compartments. The area of ​​each compartment should not exceed 500 square meters. Use a vibrator to vibrate the concrete while pouring. The vibration interval should not exceed 50cm. 2. Leveling machine start: After the concrete is initially vibrated, start the Vanse laser leveling machine (concrete leveling machine) and drive it to the poured concrete area. 3. Leveling operation: The operator controls the travel speed and scraper height of the leveling machine according to the signal of the laser receiver, so that the scraper moves along the laser plane to level the concrete. During the leveling process, pay attention to the flatness of the concrete surface and the working status of the scraper, and adjust the travel speed and scraper height in time.   (III) Quality inspection and subsequent treatment 1. Flatness inspection: Use tools such as a level and a 2m ruler to check the flatness of the leveled concrete surface. The flatness error within every 2 square meters should not exceed ±2mm. If uneven areas are found, local repairs should be made in time. 2. Surface treatment: According to construction requirements, surface finishing and roughening can be performed in the initial setting stage of concrete to improve the quality and aesthetics of the concrete surface. 3. Maintenance: After leveling, the concrete should be maintained in time. Plastic film can be covered, curing agent can be sprayed, etc., and the maintenance time should not be less than 7 days.   (I) High precision Compared with traditional leveling methods, Vanse concrete laser leveling machine can achieve higher flatness. Its advanced laser technology and precise control system can meet the construction needs of industrial plants, precision instrument workshops and other places with strict requirements on ground flatness, ensure that the ground flatness error is extremely small, and provide a high-quality foundation for subsequent production and use.   (II) High efficiency The automated leveling process reduces the time and error of manual operation and greatly improves construction efficiency. The large area coverage and adjustable walking speed of the scraper greatly shorten the construction period, reduce labor costs and time costs, and bring higher economic benefits to users.   (III) Strong adaptability Vanse laser leveling machine can adapt to different types of concrete and construction site conditions. Whether it is a large or small area, flat or with a certain slope, it can guarantee a good leveling effect. The choice of crawler and wheeled walking methods, as well as the flexible adjustment of the scraper system, enable it to cope with various complex construction environments.   (IV) Reliable quality The equipment adopts high-quality materials and advanced manufacturing processes, and the performance of each component is stable and reliable. The high precision of the laser transmitter and receiver, as well as the intelligent control system, ensure the stability and consistency during the construction process, and provide a solid guarantee for the quality of the flooring project.   (I) Quality Control 1. Equipment Calibration: Regularly calibrate the laser transmitter and the laser receiver and control system of the leveling machine to ensure that the equipment accuracy is always maintained at a high standard, providing a guarantee for the construction quality. 2. Construction Process Monitoring: During the construction process, arrange a dedicated person to be responsible for quality inspection, monitor the slump of concrete, the working parameters of the leveling machine and the flatness of the ground after leveling in real time, and deal with problems in a timely manner to ensure that the construction quality meets the requirements.   (II) Equipment Maintenance 1. Daily Maintenance: After the construction is completed, clean up the concrete residue on the leveling machine in time, check the wear of the scraper, walking system, hydraulic system and other components, lubricate the equipment and tighten the bolts and other maintenance work to extend the service life of the equipment. 2. Regular maintenance: According to the use time and working intensity of the equipment, the Vanse laser leveling machine should be regularly overhauled, the severely worn parts should be replaced, and the hydraulic oil and lubricating oil should be replaced to ensure the stable performance of the equipment and always maintain good working condition.

The construction machinery industry is becoming more and more mature, and various types of construction machinery are more and more commonly used in my country's consumer market, especially this year, concrete laser leveling machines are more and more recognized by customers. As the leader of concrete laser leveling machine, the concrete laser leveling machine produced by Shandong VANSE Machinery can realize large-scale construction, and completely eliminate all the "common quality problems" caused by the secondary method by solving the concrete surface layer at one time . It has truly achieved the effect of "three super" floors that are flat, clean, dense, high-strength, one layer as a whole, cost reduction, construction period shortening, and absolute durability. Shandong VANSE mechanical concrete laser leveling machine has several advantages compared with traditional laser leveling machines: 1. Laser alignment, high precision and low error. Traditional process leveling requires support formwork to control the elevation of the ground and pull the control line. The elevation error is large. The levelness and flatness of the entire floor cannot be guaranteed. Using a laser point-to-point emitter, it is suitable for large-area one-time paving. There is a laser measurement and control system to control the elevation in real time. There is no need for pulling wires for leveling, and there is no need for side plates in the middle to control the elevation of the ground. In this way, the elevation error caused by the vibration of the formwork (channel steel) during the construction process is avoided, and the elevation error caused by traditional manual block formwork is also reduced. 2. Reduce labor costs and double the efficiency. Traditional construction involves a large number of workers, requiring support formwork (channel steel), spotting, and paving. About 20 people are needed. The daily construction area is 700 square meters. The total number of people who use the concrete laser leveling machine is reduced by more than half compared with the traditional process. Can be operated by one person. The daily construction area is 2500-3500 square meters, which greatly reduces labor costs. 3. Better flatness and integrity. Traditional craft construction, one day of formwork and one day of watering, can only be skipped one by one for construction, which has great limitations, cannot be continuously operated, and the integrity is not good, which is likely to cause cumulative errors in construction joints. Concrete laser leveling machine can pave a large area of the floor at one time, with higher efficiency and integrity. The completion of the entire floor will make the ground integrity better, which is completely impossible for traditional construction.

    To incorporate the operation of concrete laser leveling into the project's comprehensive quality management system and achieve full-process quality control, a systematic approach is required. This is not merely about operating the machine itself, but rather managing it as a core link in the entire construction process. The following is a detailed framework and implementation plan on how to integrate it into the total quality management system in stages and at different levels: Traditional quality management relies on manual inspection and repair after pouring, while total quality management requires us to bring quality control forward and incorporate it throughout the entire process before, during and after the event. The laser leveling is an excellent tool for realizing this concept because it combines "measurement" and "leveling" into one, providing a data foundation for process control. The entire process can be divided into three main stages: This is the most crucial stage, which determines the success or failure of the subsequent assignments. Technical Preparation and briefing Specialized plan compilation: Prepare the "Specialized Construction Plan for laser leveling Machines", clearly defining key processes such as equipment selection, reference point layout rules, personnel division of labor, walking routes, pouring sequence, and joint treatment. Deepening design: Communicate with the design unit to clearly define the positions of the floor's partition joints and expansion joints on the drawings, as well as the operation zones of the laser leveling machine, to ensure that the leveling plan matches the structural design. Three-level technical briefing: Conduct layer-by-layer briefings for the company's management, project management, and work teams to ensure that all relevant personnel understand the quality objectives, operational key points, and acceptance criteria. Personnel training and qualification certification Operator certification: The operator of the laser leveling machine must undergo strict training by the equipment manufacturer or internal certification and hold a certificate to work. They not only need to understand machines, but also the characteristics of concrete. Team collaboration training: Conduct collaborative operation training for auxiliary workers (such as those responsible for loading materials, leveling, and handling edges and corners) to form an efficient operation team. Equipment and system verification Calibration of laser leveling: Before each operation, the laser emitter, receiver and elevation control system of the equipment must be calibrated and reset to zero. Establish the "Daily Inspection Form for Equipment". Reference system review: The surveyor independently reviews the laser reference network (or GPS reference) set up within the field to ensure that its absolute elevation and levelness meet the design requirements. This is the "origin" of quality and must be foolproof. Acceptance of grassroots and formwork: Base treatment: Strictly inspect the compactness, elevation and slope of the base (usually compacted crushed stone or concrete cushion). The quality of the base layer directly determines the final quality of the surface layer. Formwork erection: The top elevation of the formwork must be precise and firm and stable. The stiffness and stability of the template are the keys to preventing edge collapse and elevation loss of control. This is the execution stage, with the core being "real-time monitoring and immediate correction". Concrete incoming material control Slump management: Randomly check the slump of concrete at fixed points on the pouring site. The most suitable slump for a laser leveling is usually between 120mm and 150mm (adjusted according to specific equipment and process). If it is too high, it is prone to cracking; if it is too low, it will be difficult to level. Establish an exit mechanism for those with unqualified slump. Continuous supply guarantee: Coordinate with the mixing plant to ensure the continuity of concrete supply and avoid cold joints. Process control of laser leveling operation Guide system: Assign a dedicated person (usually a foreman or quality inspector) to check in front of the leveling whether the thickness of the loose concrete is appropriate and promptly direct adjustments. Real-time data recording: Utilize the built-in data output function of the leveling machine (if any), or have the quality inspector conduct a quick spot check on the just-leveled area using traditional tools (such as a straightedge or feeler gauge), and record the flatness data. Establish a "Laser Leveling Operation Process Record Form". Abnormal situation handling process: Clearly define the emergency response plan for abnormal situations such as equipment failure, laser signal loss, and sudden change in concrete quality (e.g., immediately suspend, switch to backup equipment, mark the problem area, etc.). Collaborative Work Management Follow-up operation: After the leveling machine is completed, personnel should be promptly arranged to handle the edge and corner treatment and bleeding treatment. The film coating or curing agent operation should be initiated during the initial setting stage to prevent surface water loss and cracking. This stage aims to confirm the achievements and form a closed loop. Digital Acceptance and Data Analysis High-precision acceptance: After the concrete reaches a certain strength, professional equipment (such as floor flatness testers, 3D laser scanners) is used for full coverage digital acceptance, generating flatness, elevation cloud maps and analysis reports. Comparison with the target: Compare the measured data with the quality targets set in the QMS (such as FF/FL values), and conduct statistics on the pass rate. Defect Analysis and traceability Conduct a root cause analysis of any areas that exceed the standard. Is it a grassroots issue? Template issue? Concrete problems? Is it still a problem with the operation of the leveling machine? Trace back using the process record sheet. Establish a quality defect database: Input typical cases, cause analysis and corrective measures into the company's knowledge base for training and improvement in subsequent projects. Outcome Feedback and System Optimization Project summary meeting: Organize a special summary to assess the quality, efficiency and cost of this laser leveling operation. Optimize standard documents: Based on the experiences and lessons learned from this practice, update the "Special Construction Plan for laser leveling Machines", "Operation Instruction Manual" and "Quality Control Point List" to achieve continuous improvement of the quality management system (PDCA cycle). To truly achieve "inclusion", it is necessary to clearly define in the system documents and organizational structure: Clarify the quality responsibility subject Project Manager: Fully responsible for the quality of the floor. Production Manager/Foreman: Responsible for the execution of operation plans and resource coordination. Quality Engineer/Quality Inspector: Responsible for independent quality supervision, inspection and record-keeping. laser leveling machine operator: Directly responsible for the quality of the leveling process. Update the quality management system documents In the company's "Quality Manual" and "Procedure Documents", add relevant chapters on "Quality Control of Mechanized Construction of Floor Engineering". Compile and improve the various operation instructions, quality standards and record forms mentioned above, making them standardized tools for the operation of the system. Utilizing information technology means (QMS software /BIM) Upload the process data and final acceptance data of the laser leveling machine to the project quality management platform to achieve data visualization. Compare the BIM model of the floor with the measured data to visually display the deviation between the construction quality and the design goals. Through the information system, the automatic push, rectification and closure process of quality issues is realized. Incorporating the operation of concrete laser leveling into the total quality management system essentially transforms an efficient construction machine into a controllable quality process that integrates personnel, methods, materials, measurements and the environment. Through the full-process management of "meticulous planning in advance, strict monitoring during the process, and scientific verification after the event", supplemented by clear responsibility systems, standardized documents and a complete information feedback mechanism, a true leap from "relying on experience" to "relying on data and processes" can be achieved, and ultimately high-quality concrete floors can be produced stably and efficiently.   Note: The parameters provided in this document are for reference only and are not mandatory.
