If you want to use the concrete laser leveling machine better, there are some prerequisites. First, you need to be familiar with the structural characteristics of the concrete laser leveling machine, and you must abide by the rules during use, which can effectively guarantee the use of the equipment. In order to allow users to use the leveling machine both to ensure the effect and to rest assured, the staff will lead everyone to look at the rules that need to be followed when operating the concrete laser leveler safely. ◤First of all, it is necessary to ensure that all parts of the concrete laser leveling machine are connected in good condition without any looseness, so as to prevent problems during the operation; ◤Add enough lubricating oil to the internal combustion frame leveler in advance to improve the flexibility of the controller so as to improve work efficiency; ◤The surface insulation part of the cable must be complete, and a little bit of damage must be treated with caution until it is completely intact. This will not only ensure the safety of construction personnel, but also the safety of passers-by. ◤After turning on the power, you need to check the rotation direction of the motor, and change the wire immediately if there is an error, so as to avoid bigger problems during work. ◤Personnel who operate the leveling machine must undergo professional training, such as not tilting and not holding too tightly during the operation, so as to avoid careless accidents. ◤During the construction process, the concrete laser leveling machine needs dense soil, which can be repeatedly tamped on the spot without moving back and forth, so that even if the result is the same, more energy will be spent on moving, which is uneconomical; ◤So how should the laser leveling machine be used?

  Slump: Slump reflects the fluidity of concrete. If the slump is too large, the concrete is too thin and soft, and it is easy to seep water and slurry when troweling, making it difficult to form a solid surface, and cracks are easy to appear on the surface after troweling; if the slump is too small, the concrete is too dry and hard, and it is difficult for the trowel blade to effectively trowel it, which will cause uneven surface and increase the workload of the trowel. Setting time: The setting time of concrete is crucial for troweling. If troweling is performed before the initial setting of concrete, the concrete is still in a plastic state and can be easily smoothed by the trowel, but troweling too early may damage the internal structure of the concrete and affect its strength; if troweling is performed after the final setting, the concrete has hardened, and it is difficult for the trowel to operate it effectively, leaving trowel marks on the surface, and it is impossible to achieve the ideal flatness and finish.   Speed: The speed of the trowel directly affects the troweling effect. If the speed is too low, the blade will not be able to vibrate and smooth the concrete surface enough, and the cement slurry on the concrete surface cannot be evenly distributed, resulting in poor surface finish; if the speed is too high, the concrete surface will be subjected to excessive centrifugal force, which may cause cement slurry splashing, and will also increase the wear and energy consumption of the machine. Power: The power determines the working capacity of the trowel. If the power is insufficient, when encountering large concrete resistance during the troweling process, the trowel may be underpowered, resulting in unsmooth rotation of the blade, affecting the troweling effect; if the power is too high, it may cause energy waste, and it is easy to cause excessive vibration and damage to the concrete surface if the operation is improper.   Operation technique: The operator's operation technique has a great impact on the troweling effect. Skilled operators can reasonably control the travel speed, direction and troweling time of the trowel according to the state of the concrete and the performance of the trowel, so that the concrete surface can achieve a flat and smooth effect; while unskilled operators may encounter problems such as uneven travel speed, overlapping or missing troweling areas, resulting in poor troweling quality. Judgment ability: Experienced operators can accurately judge the setting time and state of concrete and choose the right time to perform the troweling operation. They can also adjust the parameters and operation methods of the troweling machine in time according to the problems that occur during the troweling process, such as bubbles and trowel marks on the surface; while inexperienced operators may not be able to accurately judge these situations, thus affecting the troweling effect.   Temperature: The ambient temperature has a significant impact on the setting time and troweling effect of concrete. In a high temperature environment, the moisture of concrete evaporates quickly, the setting time is shortened, the troweling operation time window becomes smaller, and surface shrinkage cracks are prone to occur; in a low temperature environment, the setting time of concrete is prolonged, and the troweling quality may be affected by the freezing of the internal moisture of the concrete during troweling, and it will also increase the difficulty of starting the troweling machine and energy consumption. Humidity: If the ambient humidity is too high, the moisture on the concrete surface is not easy to evaporate, which will delay the setting time of the concrete, resulting in water seepage on the surface after troweling; if the humidity is too low, the moisture on the concrete surface evaporates too quickly, and problems such as surface dryness and peeling are prone to occur, affecting the troweling effect. Wind speed: Higher wind speed will accelerate the evaporation of moisture on the concrete surface, causing uneven drying of the concrete surface, increasing the difficulty of polishing, and may also cause cracks on the polished surface.
