Construction Adaptability of Laser Leveling Machine in Low Temperature or High Humidity Environments

  In recent years, with the continuous development of the economy and society, the construction demand of large areas such as parking lots, large squares, industrial plants is also increasing, because these sites mainly use concrete to pour the foundation, and then cover the floor tile or floor paint, so higher requirements are put forward for the flatness of the base layer. In order to ensure that the ground flatness after construction reaches an ideal level, it is necessary to use a concrete laser levelling machine. So, what is the difference between the construction of concrete laser levelling machine and manual construction? What are the significant construction advantages of the concrete laser leveling machine itself? █  Traditional construction method The common concrete floor construction method is to manually level, and then use a polishing machine to wipe. This method requires a lot of labor, the quality of the construction process is not controlled, the need for manual correction many times, repeated measurement and adjustment of the ground under construction, and the efficiency is not high. A large area of concrete floor construction needs to use a large number of wood or metal plates to form the side formwork in advance, and measure the height of the side formwork by the level to control the height of the concrete after laying. Due to the need to use the level for multi-point measurement, the side template must be retested after laying to ensure accuracy. Therefore, the process is prone to human error. In addition, the removal of the side template also requires a lot of labor. █  Intelligent construction method   1. Operation principle The Topcon laser transmitter is set up in advance on the construction site to provide the reference surface of the working elevation. The Topcon receiver LS-B110 fixed on the laser leveler receives the laser elevation position signal and transmits the real-time elevation position signal to the controller, which automatically controls the electric push rod or hydraulic system of the concrete laser leveler. Ensure that the receiver's elevation is at the same level as the reference plane, and the leveling machine mechanism can be spread according to the set height.   2. Construction advantages The advantages of using concrete laser leveling machine for concrete leveling are highlighted in the following aspects: (1) It is easy to lay high-strength concrete, low-slump concrete and fiber mud condensate; (2) The construction quality is high, the leveling quality of the laser leveling machine is more than 3 times higher than that of the traditional manual construction method, and the ground is super flat; (3) Improve work efficiency and save about labor. The use of concrete laser levelling machine construction, shorten the construction time, improve work efficiency, and can save labor; (4) The heavy manual labor is changed into mechanical paving, vibrating, leveling, pulp lifting, and plastering, so that the operator is reduced, and the labor intensity is reduced to create high-quality ground; (5) The application of concrete laser levelling machine, not only than the traditional manual process to save costs, and less ground joint, later maintenance costs are greatly reduced, so that the economic benefits are significantly improved; (6) The use of concrete laser levelling machine can achieve large area construction, reduce a large number of construction joints, concrete collapse can be reduced, concrete strength is guaranteed, so that the ground integrity is good, not easy to crack. Summary of this chapter: Although the concrete laser levelling machine is an emerging new equipment with excellent technology in recent years, it is widely used in airport runways, high-speed rail platforms, large workshop pavements and other projects with high requirements for ground smoothness. If it can be widely popularized and promoted, it will bring very considerable construction benefits.

In the field of concrete construction, concrete laser leveling machine (concrete laser leveling machine or concrete laser leveler) has become a key equipment to improve construction efficiency and quality. With the vigorous development of the construction industry, the demand for high-precision, large-area concrete construction continues to grow, and the application of concrete laser leveling machine is becoming more and more extensive. According to a market research report, the global concrete laser leveling machine market size is expected to reach US$1.76 billion in 2025, with an annual growth rate of approximately 11.4%. During long-term high-intensity use, how to extend the service life of the concrete laser leveling machine has become the focus of many users. This is not only related to the return on equipment investment, but also affects the smooth progress and cost control of construction projects.   After each operation with a concrete laser leveling machine, timely cleaning is essential. Since the equipment will be exposed to a large amount of concrete, mud and other impurities during operation, if it is not cleaned in time, these substances will adhere to the surface of the equipment and key components, accelerating component wear. For example, the body shell, leveling blade, vibrating device and other parts can be washed with a high-pressure water gun (but it should be noted that it is strictly forbidden to directly aim the water gun at the mesh part of the body to prevent water from entering the body and causing a short circuit) to remove the concrete residue and dust on the surface. For some stubborn stains that are difficult to wash off, use a soft cloth dipped in a neutral detergent dilution to wipe. Do not use strong alkali or strong acid cleaning agents to avoid corrosion of the paint and electroplating layer on the surface of the equipment, affecting the appearance and reducing the protective performance. Regularly check the connection and tightening of each component. During the operation of the equipment, the connecting bolts may become loose or even broken due to factors such as vibration and impact. For example, the connecting bolts of the frame, walking mechanism, laser transmitting and receiving device of the laser leveling machine should be carefully checked before and after each operation. If they are loose, tighten them in time. If the bolts are broken, they need to be replaced immediately. At the same time, check whether there is leakage in all parts of the equipment, including engine oil, coolant, hydraulic oil of the hydraulic system, etc. Once leakage is found, the cause should be promptly investigated and repaired to avoid problems such as poor lubrication and overheating of components due to oil leakage, which will affect the service life of the equipment. The timely replacement of wearing parts is the key to ensuring the continuous and stable operation of the equipment. For example, the leveling scraper, vibrator, tires (or rubber tracks) of the leveling machine will wear faster during frequent use. Generally speaking, the wearing parts should be checked after each use. If the wear exceeds the prescribed limit, they should be replaced immediately. Even if the wearing parts do not seem to be damaged during normal use, it is recommended to replace them every six months to ensure that the overall performance of the equipment is not affected. For example, a severely worn leveling scraper cannot effectively scrape the concrete, which will cause the ground flatness to decrease, and will also increase the workload of other parts of the equipment, accelerating the overall loss of the equipment.   In a high temperature environment, the concrete laser leveling machine faces many challenges. The engine is prone to overheating, resulting in power reduction and increased wear of parts. Therefore, when constructing in high temperatures in summer, first ensure that the engine cooling system is working properly. Before daily operation, check the coolant level and add it in time if it is insufficient; regularly clean the dust and debris on the surface of the radiator to ensure that the heat dissipation duct is unobstructed. When the engine temperature is too high, you should choose a cool area to stop and cool down. Do not rush to add cooling water. You need to let the engine idle for a while and add it after the temperature drops slightly to prevent the engine cylinder from cracking due to excessive temperature difference. At the same time, high temperature will also affect the performance of the hydraulic system. Check the hydraulic oil temperature frequently. If the oil temperature is too high, stop the machine for a rest to avoid long-term operation of the equipment at high temperatures. For example, in some southern regions during summer construction, if you do not pay attention to the heat dissipation of the equipment, it may cause the hydraulic system seals to age faster and leak oil, which will seriously affect the normal use of the equipment. High humidity environment can easily cause the metal parts of the concrete laser leveling machine to rust and corrode, especially when constructing in coastal areas or rainy seasons. To cope with high humidity environments, the equipment should be parked in a dry place and avoid being placed in the open air. If it is unavoidable to operate in a humid environment, anti-rust oil can be applied to the surface of the equipment, especially to parts that are prone to rust, such as the frame and chassis. At the same time, the electrical circuit should be checked regularly to prevent short circuit failures caused by moisture. For the battery of the equipment, it is necessary to keep it clean and dry, check the electrolyte level and density regularly, and replenish distilled water in time to ensure good battery performance. For example, if the laser leveling machine used for a long time in a high humidity environment does not pay attention to anti-rust treatment, it may cause problems such as frame rust and strength reduction in a short period of time, affecting the safety and service life of the equipment. Concrete contains alkaline substances. If the protection is not appropriate during long-term contact, it will cause corrosion to the components of the concrete laser leveling machine. For parts that are in direct contact with concrete, such as leveling blades, vibrating devices, etc., they can be made of corrosion-resistant materials or undergo special surface treatment to improve their resistance to alkali corrosion. After each operation, clean the equipment thoroughly to remove residual concrete and prevent alkaline substances from adhering to the surface of the equipment for a long time. In a high-alkaline environment, attention should also be paid to the lubrication system of the equipment, and lubricating oils and greases with good alkali resistance should be selected and replaced regularly to ensure that all moving parts are well lubricated and reduce the occurrence of failures caused by corrosion and wear. For example, in the construction of some industrial plant floors, due to the strong alkalinity of concrete, if effective protective measures are not taken, the key components of the equipment may be severely corroded in a short period of time, shortening the service life of the equipment.   Strictly operate in accordance with the rated working parameters of the concrete laser leveling machine to avoid operating in a condition that exceeds the equipment's bearing capacity. Overload operation will cause excessive pressure on the engine, hydraulic system, transmission components, etc., accelerate the wear of parts, and even cause equipment failure. For example, behaviors such as leveling thickness exceeding the maximum thickness specified by the equipment and forced operation on a site with a large slope will cause damage to the equipment. As an equipment manager, you should ensure that the operator is familiar with the equipment performance and operating procedures, and strictly prohibit illegal operations. Before construction, arrange construction tasks reasonably according to actual working conditions to ensure that the equipment operates stably within the normal load range. During the operation of the equipment, try to ensure smooth operation and avoid violent operations such as sudden acceleration, sudden braking and frequent steering. Sudden acceleration and sudden braking will cause the engine and transmission system to bear greater impact force instantly, which may easily cause damage to parts; frequent steering will aggravate the wear of tires (or tracks) and steering mechanisms. After starting the equipment, the engine should be allowed to idle for a period of time to allow all parts to be fully lubricated before operation. During the leveling operation, keep the equipment moving at a uniform speed to avoid speed fluctuations, which can not only ensure the construction quality but also reduce the wear of the equipment. For example, when driving a concrete laser leveler, smoothly controlling the throttle and steering wheel can effectively extend the service life of key parts of the equipment. The correct start and stop sequence also has an important impact on the service life of the concrete laser leveler. Before starting the equipment, check the environment around the equipment to ensure that there are no obstacles; check whether the liquid levels of fuel, engine oil, coolant, hydraulic oil, etc. are normal, and whether the indications of various instruments are normal. When starting, first turn the key to the power-on position, wait for the instrument self-check to complete, and then start the engine. After the engine is started, let it idle for a few minutes, observe the engine sound, vibration and whether the display of each instrument is normal, and then proceed to the next step after confirming that it is correct. When shutting down, first park the equipment on a flat and solid ground, lower the working device to the lowest position, and then turn off the engine. If the equipment is not used for a long time, the equipment should be sealed and maintained in accordance with the requirements of the equipment manual, such as draining fuel and coolant, lubricating and protecting key parts, etc. For example, the wrong starting method, such as forcibly starting the engine before the equipment completes the self-check, may damage the engine control system and affect the normal use of the equipment.   The hydraulic system is an important part of the concrete laser leveling machine, and regular maintenance is essential. Hydraulic oil will be contaminated and its performance will deteriorate during use, so the hydraulic oil should be replaced regularly. Under normal circumstances, the hydraulic oil should be replaced every 1,000 working hours or so. The specific replacement cycle can be adjusted appropriately according to the equipment use environment and the oil quality monitoring results. When replacing the hydraulic oil, use a clean container to hold the oil. The hydraulic oil must be filtered through the oil filter before adding it to the hydraulic oil tank to ensure that the oil is clean. At the same time, clean the hydraulic oil radiator regularly to ensure good heat dissipation and prevent the hydraulic system from malfunctioning due to excessive oil temperature. In addition, the replacement cycle of the hydraulic oil filter should also be appropriately shortened, generally 750 hours is appropriate. When replacing a new filter, check carefully. It is strictly forbidden to use a deformed, contaminated or rusted filter. For example, at some construction sites, due to the harsh environment, the hydraulic oil is easily contaminated by dust and impurities. If the filter and hydraulic oil are not replaced in time, it may cause blockage, leakage and other faults in the hydraulic system, seriously affecting the normal operation of the equipment. Regularly check the electrical system of the concrete laser leveling machine to ensure that all electrical components are firmly connected and the circuits are not damaged or aged. Check the performance of the laser transmitting and receiving device to ensure that the laser signal is stable and accurate. Start the engine once every two months, charge the battery, and run all hydraulic actuators, such as rotary hydraulic motors, telescopic cylinders, etc., to prevent battery loss and rust and jamming of hydraulic system components. Do not remove the battery from the machine at will to avoid the loss of internal software program failures in the equipment control. At the same time, pay attention to check the grounding of the electrical system to ensure that the grounding is good to prevent safety accidents caused by leakage. For example, if the electrical line is aging and damaged, it may cause a short circuit, causing a fire, and endangering the safety of equipment and personnel. Perform a comprehensive performance test on the concrete laser leveling machine every once in a while (such as half a year or a year). The test content includes key performance indicators such as leveling accuracy, work efficiency, engine power, and hydraulic system pressure. Through testing, potential problems with the equipment can be discovered in time, and targeted repairs and adjustments can be made. For example, if the leveling accuracy is found to be reduced, it may be due to laser system failure, wear of the leveling blade, or looseness of the mechanical parts of the equipment. It is necessary to check and repair them one by one to ensure that the equipment always maintains a good working condition and extends its service life.

In what cases does the concrete laser leveling machine need to be adjusted or suspended? As a highly efficient modern construction equipment, the concrete laser leveling machine plays an important role in the construction of concrete floors with its precise leveling ability and high operating efficiency. However, in the actual construction process, due to the influence of various factors, it is sometimes necessary to adjust or suspend the construction of the concrete laser leveling machine. This article will elaborate on the specific circumstances in which the concrete laser leveling machine needs to be adjusted or suspended from the aspects of unsuitable environmental conditions, mechanical equipment failure, safety considerations for construction personnel, insufficient or abnormal material supply, changes in construction quality requirements, substandard ground conditions, climate abruptness or natural disasters, and updates or requirements of regulations and standards. 1. Unsuitable environmental conditions Environmental conditions are one of the key factors affecting the normal operation of the concrete laser leveling machine. In the following cases, it is necessary to consider adjusting or suspending construction: First, when the wind force at the construction site is too strong, the concrete surface is easily affected by the wind and causes drying and cracking. Therefore, when the wind force reaches a certain level, the construction should be suspended and the work should be continued after the wind force weakens. Secondly, temperature and humidity are also important factors affecting concrete construction. In high or low temperature environments, the setting time and strength of concrete will change, which may lead to poor leveling effect or other problems. Similarly, too high or too low temperature will also have a negative impact on the construction quality of concrete. Therefore, under unsuitable temperature and humidity conditions, it is necessary to adjust the mix ratio of concrete or suspend construction. 2. Mechanical equipment failure As a mechanical equipment, the concrete laser leveling machine may fail or abnormally during long-term use. The following are some situations that require special attention: First, when the laser transmitter or receiver of the laser leveling machine fails, it will affect the leveling accuracy and effect. At this time, the construction should be stopped immediately and the equipment should be repaired or replaced. Secondly, when the power system, transmission system or control system of the leveling machine fails, it may also cause the equipment to fail to work properly or the leveling effect is poor. In this case, it is also necessary to suspend construction and troubleshoot and repair the fault. 3. Safety considerations for construction personnel Safety is always the primary consideration during the construction process. In the following cases, in order to ensure the safety of construction workers, it is necessary to adjust or suspend the construction of the concrete laser leveling machine: First, when there are safety hazards or accident risks at the construction site, such as falling objects from high altitudes, exposed electrical lines, etc., the construction should be suspended immediately, and the work should be continued after the safety hazards are eliminated. Secondly, the physical condition of the construction workers is also an important factor affecting construction safety. When the construction workers are tired, unwell or make operating errors, the work plan should be adjusted in time or replacement personnel should be arranged to ensure construction safety and quality. 4. Insufficient or abnormal material supply During the construction of the concrete laser leveling machine, the quality and supply of concrete materials are directly related to the leveling effect and construction progress. The following are some situations that need attention: First, when the supply of concrete materials is insufficient, it will lead to construction interruption or delay in progress. In this case, it is necessary to adjust the construction plan in time, increase material reserves or adjust the source of materials. Secondly, if there are quality problems with the concrete materials, such as abnormal setting time and substandard strength, it will have a negative impact on the leveling effect. At this time, the construction should be suspended, and the quality of the concrete materials should be inspected and adjusted. 5. Changes in construction quality requirements During the construction process, the construction quality is sometimes adjusted or changed according to the actual situation or the requirements of the owner. In this case, the concrete laser leveling machine needs to be adjusted accordingly or the construction needs to be suspended. For example, when the owner's requirements for the flatness or levelness of the ground change, the parameters of the leveling machine need to be reset or the leveling process needs to be adjusted. Similarly, if the ground needs to be treated specially or the construction process needs to be improved, the construction needs to be suspended and the relevant measures need to be implemented before continuing the operation. 6. The ground conditions do not meet the standard Ground conditions are the basis for the construction of concrete laser leveling machines. When the ground conditions do not meet the construction requirements, it will affect the leveling effect and construction progress. The following are some common situations. First, when there are unevenness, cracks or debris on the ground, pretreatment or cleaning work needs to be carried out first to ensure that the ground is flat and clean. If the pretreatment work is not completed or the effect is not ideal, the construction should be suspended and the ground conditions should be continued after the requirements are met. Secondly, when the humidity or temperature of the ground does not meet the construction requirements, it will also affect the leveling effect. In this case, corresponding measures need to be taken to adjust the ground conditions, such as increasing ventilation, heating or cooling, etc. 7. Climate change or natural disasters Climate change or natural disasters are factors that cannot be predicted and avoided during the construction process. In the following cases, the construction of the concrete laser leveling machine needs to be suspended immediately: First, when encountering sudden severe weather such as strong winds, heavy rains, thunder and lightning, in order to ensure the safety of construction workers and the stability of equipment, construction should be stopped immediately and corresponding protective measures should be taken. Secondly, when natural disasters such as earthquakes and floods occur, priority should be given to personnel safety, all construction activities should be suspended, and evaluation and resumption of work should be carried out after the disaster has passed. 8. Updates or requirements of regulations and standards With the continuous updating and improvement of regulations and standards in the construction industry, it is sometimes necessary to adjust or suspend the construction of the concrete laser leveling machine. For example, when new safety regulations or environmental protection requirements are introduced, it may be necessary to update and improve the safety measures or environmental protection measures in the construction process. In this case, it is necessary to suspend construction, train and educate relevant personnel, and ensure that the construction meets the requirements of new regulations and standards. In summary, there are many situations in which the concrete laser leveling machine needs to be adjusted or suspended during construction. In order to ensure the safety, quality and efficiency of construction, it is necessary to pay close attention to the changes in various factors during the construction process and take corresponding measures in a timely manner according to the actual situation. At the same time, it is also necessary to strengthen the training and education of construction personnel, improve their professional skills and safety awareness, and ensure the smooth progress of the construction process. 9. Equipment maintenance cycle As a mechanical equipment, the normal operation of the concrete laser leveling machine is inseparable from regular maintenance. When the equipment reaches the predetermined maintenance cycle, it is necessary to suspend construction and conduct comprehensive inspection, cleaning and lubrication of the equipment. This not only ensures the normal operation of the equipment and prolongs its service life, but also avoids construction interruptions and quality problems caused by equipment failure. During the maintenance process, attention should be paid to the vulnerable parts and key components of the equipment, such as laser transmitters, receivers, transmission systems, hydraulic systems, etc., and parts with severe dry wear or damage should be replaced or repaired in time. At the same time, dust and debris on the surface of the equipment should be cleaned to keep the equipment clean and beautiful. 10. Construction plan adjustment During the construction process, sometimes the construction plan needs to be adjusted due to various reasons. For example, when the owner puts forward new requirements or design changes, the construction plan needs to be re-formulated. In addition, when the construction progress is delayed due to external factors, the construction plan also needs to be adjusted to ensure that the project is completed on time. In this case, it is necessary to suspend the construction of the concrete laser leveling machine, communicate and coordinate with relevant personnel, re-formulate the construction plan and adjust the use arrangement of the equipment. Through reasonable adjustment of the construction plan, the smooth progress and timely completion of the project can be ensured. In summary, the concrete laser leveling machine needs to consider adjustment or suspension of construction in the case of unsuitable environmental conditions, mechanical equipment failure, safety considerations for construction personnel, insufficient or abnormal material supply, changes in construction quality requirements, ground conditions that do not meet standards, climate changes or natural disasters, regulatory standards updates or requirements, equipment maintenance cycles, and construction plan adjustments. In the actual construction process, we should pay close attention to the changes in these factors and take corresponding measures according to the actual situation to ensure the safety, quality and efficiency of the construction. At the same time, we should also strengthen the training and education of construction personnel, improve their professional skills and safety awareness, and provide strong guarantees for the smooth progress of the project. Because the concrete laser leveling machine involves complex operation and maintenance, the specific situation in the actual construction process may be more complicated. Therefore, it is recommended to keep in close contact with equipment manufacturers, construction units and relevant experts in the actual construction process to consult and solve problems encountered in the construction in a timely manner. Through continuous practice and experience accumulation, we will continuously improve the application level of concrete laser leveling machines in construction. Please note that the above content is a summary based on existing knowledge and experience, and does not represent all possible situations and solutions. In the actual construction process, it is necessary to make judgments and decisions based on the specific situation. At the same time, with the continuous advancement of technology and the continuous development of the industry, the application and maintenance of concrete laser leveling machines may also have new changes and requirements. Therefore, it is recommended that relevant personnel continue to learn and pay attention to industry trends in order to adapt to and master new technologies and methods in a timely manner.
