Concrete laser leveling machine traditional method construction process

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.

– Carefully check whether the appearance of the equipment has signs of damage, such as whether the fuselage has cracks or deformation, especially whether the shell of the laser receiver and transmitter is intact. Because these parts are relatively delicate, damage to the shell may affect their performance. – Check the condition of the tires (if it is a wheeled leveling machine) or the crawler (if it is a crawler leveling machine), check whether the tires have obvious wear and scratches or whether the air pressure is normal (the tire pressure should generally be kept within a certain range as required by the equipment manual, such as 3-4 atmospheres); whether the crawler has loose or broken links, etc. – Check whether the bolts and nuts at each connection are tightened. Focus on checking the connection between the working parts such as scrapers and spiral feeders and the fuselage, because these parts will generate greater vibration and force during work, and loose bolts may cause parts to fall off or work abnormally. You can use a wrench to properly tighten the bolts at key locations. – Check whether the connection between the hydraulic and electrical lines is good. Make sure that there is no leakage in the hydraulic lines and there should be no oil stains on the pipe joints; the plugs and sockets of the electrical lines should be tightly connected, and the wires should not be damaged or aged. – Operate strictly in accordance with the operating manual and avoid sudden acceleration, sudden braking or oversteering. For example, during the movement of the leveler, the speed should be controlled smoothly to avoid sudden changes in speed that cause the machine to vibrate violently, which may damage the internal structure of the machine and the laser calibration system. – Pay attention to the working status of the equipment, including the sound and temperature of the engine (if it is a fuel type) or the motor (if it is an electric type), as well as the operation of each working part (such as scraper, distributor, vibrator, etc.). If abnormal sounds (such as sharp friction sounds, impact sounds) or working parts shake or stagnate, stop the operation immediately and check the cause. – Make sure the lenses of the laser transmitter and receiver are clean. In the case of a bad working environment (such as dust, mortar splashing, etc.), the lens should be cleaned regularly. You can use a clean, soft, wet cloth to gently wipe the lens surface to avoid scratching the lens. – Pay attention to the strength and stability of the laser signal. If the laser signal is found to be interrupted or unstable, it may be due to the position of the transmitter or receiver being offset, the battery being low (for portable laser equipment), or being interfered with by the outside world. The position of the equipment should be adjusted in time, the battery should be replaced, or the interference source should be eliminated. – After each work, use a high-pressure water gun (be careful not to use too high a pressure to avoid damaging the equipment) or a soft brush, wet cloth and other tools to remove concrete residues, dust and other debris from the surface of the equipment. For hardened concrete that is difficult to remove, a special cleaning agent can be used for cleaning. – Focus on cleaning working parts, such as scrapers, blades of spiral feeders, etc., to ensure that there is no concrete residue on these parts to avoid affecting the accuracy and efficiency of the next work. At the same time, clean the bottom of the body to prevent the residual concrete from solidifying during the parking process of the equipment, affecting the normal placement of the equipment and the next start-up. – Lubricate key parts regularly according to the frequency of use and working intensity of the equipment. For example, the bearings, joints, chains (if any), etc. of the equipment should use appropriate lubricants (such as lithium-based grease). Generally, a simple lubrication check is performed every 8-10 working hours, and a comprehensive lubrication is performed every 50-100 working hours. – For the hydraulic system, check the oil level and oil quality of the hydraulic oil. The oil level should be kept within the specified scale range of the hydraulic oil tank. If the oil level is too low, a qualified hydraulic oil of the same model should be added; at the same time, observe the color and transparency of the hydraulic oil. If the hydraulic oil is found to be black, turbid or has a peculiar smell, it may be that the hydraulic oil is contaminated or aged. The hydraulic oil should be replaced in time. It is generally recommended to replace the hydraulic oil every 1000-1500 hours. – Store the equipment in a dry and well-ventilated indoor environment to prevent the equipment from getting damp and rusting. If it can only be stored outdoors, the equipment should be covered with a waterproof cloth to prevent rain, dew, etc. from corroding the equipment. – During the storage period, the scraper, spreader and other working parts of the equipment can be raised to make the tires or tracks a certain distance from the ground (such as using blocks to raise them). This can reduce the pressure of the equipment's own weight on the tires, tracks and chassis and extend the service life of these parts. At the same time, disconnect the power supply of the equipment (if it is an electric equipment) or close the fuel valve (if it is a fuel equipment), and remove the battery (if it is easy to remove) to prevent battery leakage or fuel leakage.

The concrete laser leveling machine can meet the construction requirements of large area, high flatness and levelness. It plays a very important role in the construction process. After the equipment is used, I believe everyone knows about the maintenance of the leveling machine. In this article, our staff will explain to you the three major maintenance misunderstandings of the concrete laser leveling machine. 1. THE BOLTS ARE TOO TIGHT There are many bolts and nuts on the concrete laser leveling machine. In order to make the connection reliable, it should be ensured that it has sufficient pre-tightening force. However, it should not be mistaken to think that the tighter the bolt is, the better. Blindly increasing the torque of the bolt will not only cause permanent deformation of the fastener due to excessive external force, but also cause the thread to slip or the screw to break due to excessive tension. 2. THE TIRE PRESSURE IS TOO HIGH The tire inflation pressure of the concrete laser leveling machine is the main factor that determines its service life and work quality. When the air pressure is too low, the deformation of the carcass increases, which will cause an increase in internal stress, and accelerate rubber aging and cord fatigue; at the same time, the rolling resistance increases, so the tire shoulder wear increases. However, when the inflation pressure is too high, the tire cord will generate a lot of tension, the resistance to impact will be weakened, and the rock edges will easily damage the tire; at the same time, the tire tread will wear more and cause the tire to slip, which will reduce the working efficiency of the concrete laser leveling machine. 3. ONLY DRAIN THE OIL IN THE OIL TANK WHEN CHANGING THE HYDRAULIC OIL The concrete laser leveling machine has many hydraulic components and needs sufficient hydraulic oil. Whenever the hydraulic oil needs to be replaced due to long-term use and deterioration, there will always be people who mistakenly think that it is only necessary to drain the oil in the hydraulic oil and think that it is enough to fill up new hydraulic oil. In fact, the correct oil change procedure should first let go of the hydraulic oil in the hydraulic oil tank, then clean the oil tank and add new hydraulic oil; then remove the circuit main pipe, start the engine and run it at a low speed, and the oil pump truck will be operated manually. If you have maintenance misunderstandings mentioned in the above article when you are maintaining the concrete laser leveling machine, I hope you can correct it in time and adopt the correct maintenance method to avoid machine failure due to improper maintenance. We will continue to organize and publish information about levelings, and you are welcome to pay attention to our website.
