What is the operation method of laser leveling machine?

    The working efficiency of the concrete laser leveling machine is affected by many factors such as equipment debugging, operating specifications, and construction planning. The following are some operating tips and precautions that can improve its working efficiency: – Survey the construction site in advance, clarify the elevation benchmark (such as building elevation, design slope), and ensure that the installation position of the laser transmitter can cover the entire construction area to avoid blind spots. – Divide the construction blocks according to the size of the site (such as 500-1000㎡ per block), and plan the route of the leveling machine (it is recommended to use a "U-shaped" or "S-shaped" route to reduce round trips). – After starting up, calibrate the height consistency between the laser receiver and the leveling machine scraper, and ensure that the error is ≤2mm through manual fine-tuning (the scraper can be raised and lowered multiple times on the open ground for testing). – Check the hydraulic system pressure (usually 12-15MPa) and motor speed (scraper motor speed needs to be stable at 2000-2500 rpm) to avoid affecting the leveling accuracy due to insufficient power. – Adopt the method of "segmented spreading, leveling as you spread": When the concrete tank truck unloads, first pile the material at the edge of the block, and then use the loader or manual to spread the material to a thickness of 20-30cm (slightly higher than the design elevation by 5-10mm, leaving room for vibration settlement). – The spreading speed matches the travel speed of the leveler (it is recommended that the speed of the leveler be controlled at 1-2 meters/minute) to avoid spreading too slowly to cause initial setting of the concrete, or spreading too quickly to cause accumulation and rolling. – Starting stage: Start the laser receiver first, wait for the equipment to identify the reference elevation, slowly lower the scraper, cut into the concrete at an angle of 10-15° (reduce initial resistance), and turn on the vibration function at the same time (vibration frequency is recommended to be 50-60Hz). – Travel process: Keep the machine body stable, avoid sudden acceleration or sudden braking (speed fluctuations will cause elevation deviation); if there are local bulges or depressions, the scraper height can be adjusted in real time through the control panel (each adjustment amount ≤3mm), and repeat the rolling 2-3 times. – Edge and corner treatment: For edges that the leveling machine cannot cover (such as wall edges and column bases), use steel chisels or small vibrators to assist in leveling in advance, or install baffles (the height is consistent with the design elevation) before construction to reduce the amount of manual repairs in the later stage. – When the leveler is vibrating, it can be matched with manual auxiliary finishing: 2-3 meters behind the leveler, use an aluminum alloy scraper to scrape again along the scraper track to eliminate local ripples and promote slurry on the concrete surface (the slurry thickness should be 2-3mm). – If the slump of concrete is low (≤120mm), you can spray cement slurry (water-cement ratio 0.4-0.5) in the leveling process to avoid leveling difficulties due to dry surface. – Regularly clean the concrete lumps at the bottom of the scraper (clean once every 1 hour of construction) to avoid lumps affecting elevation control; check the tire pressure (recommended 2.5-3.0bar) to ensure the level of the machine body. – If the laser signal is interrupted during construction (such as the transmitter is blocked), stop the machine immediately and manually mark the current position. After the signal is restored, recalibrate from the mark to avoid blind operation and error accumulation. – 2-4 hours after leveling is completed (depending on the temperature), cover with plastic film or spray curing agent to prevent the concrete surface from dehydrating and cracking; personnel or machinery are prohibited from entering the construction area too early during the maintenance period (at least 7 days of maintenance). – Record the construction time, equipment fuel consumption, labor input and other data of each block, analyze efficiency bottlenecks (such as slow material spreading speed, equipment failure and shutdown), and optimize the next construction process. – Large slope site: Adjust the slope parameters of the laser transmitter (such as 1% slope), and use the "low speed + multiple round trips" mode when the leveling machine is moving. The scraper inclination angle is increased to 20° to ensure uniform slope. – Large-area continuous construction: Equip 2 leveling machines for alternating operations, one for rough leveling and one for fine leveling, and arrange special personnel to track laser signals to improve construction continuity. The above techniques can significantly improve the construction efficiency of the concrete laser leveling machine (the average daily construction volume of a single device in a conventional site can reach 2000-3000㎡), while ensuring that the flatness error is ≤3mm (3-meter ruler detection). When operating, it is necessary to flexibly adjust the equipment model and concrete characteristics, and participate in manufacturer training when necessary to master the optimal parameters of the equipment.     Click the below to jump immediately!!!

Safety measures in concrete floor construction Concrete floor construction is a complex project involving many links, among which safety issues are particularly critical. From safety preparation before construction to management of the construction site, to the operation of mechanical equipment, personal protection and equipment, high-altitude operations and protection, electrical safety and fire prevention, as well as emergency handling and rescue, each link is directly related to the life safety of construction personnel and the smooth progress of the project. Therefore, this article will focus on these aspects and discuss in detail the safety measures in concrete floor construction: 1. Safety preparation before construction Safety preparation before construction is the basis for ensuring the smooth progress of concrete floor construction. First of all, the construction unit should formulate a detailed safety construction plan, clarify the safety construction goals, responsible persons and safety measures, and conduct safety technical briefings for construction personnel so that they can fully understand the safety risks and countermeasures that may be encountered during construction. Secondly, a comprehensive inspection should be carried out on the construction site to eliminate safety hazards, such as checking whether the construction power lines are intact and whether the mechanical equipment is operating normally. At the same time, according to the needs of the construction, the construction area should be reasonably arranged, and obvious safety warning signs should be set up to ensure that construction personnel can clearly identify dangerous areas. 2. Construction site management Construction site management is an important link to ensure the safety of concrete floor construction. The construction unit should establish a sound construction site management system and clarify various safety management regulations, such as prohibiting smoking at the construction site and prohibiting the random discarding of construction waste. At the same time, a dedicated person should be set up to be responsible for on-site safety management, regularly inspect the construction site, and promptly correct violations. In addition, the construction site should be kept clean and orderly, and construction materials and equipment should be stored in categories to avoid confusion and misoperation. 3. Safety of mechanical equipment operation Concrete floor construction involves a large number of mechanical equipment, such as mixers, rollers, pumping equipment, etc. In order to ensure the safety of mechanical equipment operation, first of all, it should be ensured that the operator has the corresponding operating qualifications and skills, and is familiar with the working principle and operating procedures of mechanical equipment. Secondly, mechanical equipment should be regularly maintained to ensure that it is in good working condition. At the same time, when operating mechanical equipment, it should be strictly carried out in accordance with the operating procedures, and overload operation or illegal operation is prohibited. 4. Personal protection and equipment Construction workers in concrete floor construction need to wear appropriate personal protective equipment to reduce the risk of injury. First of all, construction workers should wear basic protective equipment such as safety helmets, safety shoes and protective glasses. To deal with possible injuries such as falling objects and splashes. Secondly, depending on the construction environment, construction workers should also wear specific protective equipment such as dustproof mouthpieces and anti-noise earplugs to deal with occupational hazards such as dust and noise. In addition, construction units should regularly check and replace personal protective equipment to ensure that it is always in an effective state. 5. High-altitude work and protection In the construction of concrete floors, high-altitude work is inevitable. In order to ensure the safety of high-altitude work, construction units should set up special safety nets, safety fibers and other protective facilities to prevent construction workers from falling and causing accidents. At the same time, construction workers should wear safety belts when working at heights, and ensure that the connection between the safety belts and the fixed points is firm and reliable. In addition, construction units should also regularly inspect the high-altitude work areas to eliminate potential safety hazards in a timely manner. 6. Electrical safety and fire prevention Electrical safety and fire prevention are safety issues that require special attention in the construction of concrete floors. Construction units should strictly abide by the relevant national regulations on electrical safety and fire prevention to ensure that the electrical equipment and lines at the construction site are safe and reliable. At the same time, the construction site should be equipped with a sufficient number of fire-fighting equipment and facilities, such as fire extinguishers, fire hydrants, etc., to deal with possible fire accidents. In addition, construction workers should master basic firefighting knowledge and skills, and be able to quickly take effective countermeasures when a fire occurs. 7. Emergency handling and rescue Although we can take various preventive measures to reduce the safety risks in concrete floor construction, accidents may still occur. Therefore, it is crucial to establish a sound emergency handling and rescue mechanism. The construction unit should formulate a detailed emergency plan to clarify the response measures and rescue procedures for various accidents. At the same time, emergency drills should be organized regularly to improve the emergency handling capabilities and rescue skills of construction personnel. In the event of an accident, the construction unit should immediately activate the emergency plan and quickly organize rescue forces to deal with it, minimizing the losses caused by the accident. In summary, safety measures in concrete floor construction involve many aspects, which require the joint efforts of construction units and construction personnel. By strengthening pre-construction safety preparation, construction site management, mechanical equipment operation safety, personal protection and equipment, high-altitude operations and protection, electrical safety and fire prevention, and emergency handling and rescue, we can effectively reduce the safety risks in concrete floor construction and ensure the life safety of construction personnel and the smooth progress of the project. At the same time, construction units and construction personnel should continue to learn new knowledge and master new technologies to adapt to the ever-changing safety needs and challenges in concrete floor construction.
