Solution: 1. Set up obvious safety warning signs and protective measures at the construction site to ensure the safety of construction workers. 2. Provide safety education and training to construction personnel to improve their safety awareness and self-protection capabilities. 3. Develop emergency plans to ensure that measures can be taken quickly in emergencies to ensure the safety of construction workers. In short, during the construction process of concrete laser leveling machine, it is necessary to formulate corresponding treatment plans for various common technical problems to ensure construction quality and safety. At the same time, measures such as strengthening on-site management, improving the quality of operators, and optimizing the construction process are also An effective way to improve construction efficiency and quality.

Concrete curing is a key link to ensure the quality of concrete. The following points need to be noted: 1. Maintain appropriate humidity and temperature: During concrete curing, appropriate humidity and temperature should be maintained to promote the hardening and strength development of the concrete. Excessively high temperature and leakage may cause concrete to crack or deform, while too low temperature and humidity may cause drying shrinkage cracks on the concrete surface. Therefore, appropriate moisturizing and heat preservation measures need to be taken according to specific maintenance conditions and requirements. 2. Avoid excessive exposure time: During the setting curing period, the exposure time of surface mixing should be minimized, and the exposed surface of the concrete should be tightly covered in a timely manner to prevent surface moisture from evaporating. Before the concrete of the exposed surface protective layer is initially set, the covering should be rolled up, and the surface should be rubbed with a trowel at least twice to make it flat and then covered again. At this time, care should be taken that the covering should not directly contact the concrete surface until the concrete is finally set. 3. Increase the thickness of the protective layer appropriately: In order to increase the wear resistance and durability of concrete, the thickness of the protective layer can be appropriately increased. When pouring concrete, you can lay a layer of plastic film or wet cloth on the surface to keep the concrete surface moist and smooth. During the maintenance period, the thickness of the protective layer should be checked regularly to ensure that it meets the design requirements. 4. Control the construction temperature: During the concrete construction process, the construction temperature should be controlled to avoid excessively high or low temperatures affecting the quality of the concrete. During summer construction, measures should be taken to reduce the temperature of concrete entering the mold to avoid the phenomenon of "thermal bridge"; during construction in winter, measures should be taken to increase the temperature of concrete entering the mold to avoid the phenomenon of "cold bridge". 5. Regular inspection and maintenance: During the concrete curing period, the concrete structure should be inspected and maintained regularly to ensure its quality and safety. If cracks, deformation or other problems are found in the concrete structure, timely measures should be taken to repair and reinforce it. In short, concrete curing is a key link to ensure the quality of concrete. It is necessary to pay attention to maintaining appropriate humidity and temperature, avoiding excessive exposure time, appropriately increasing the thickness of the protective layer, controlling construction temperature, and regular inspection and maintenance. Only in this way can we ensure that the strength and durability of the concrete structure meet the design requirements and provide a strong guarantee for the safety and quality of the construction project.

When leveling the road surface, the requirements for smoothness are still relatively high. This is also because the smoothness of the road surface also plays a big role in whether the environment is beautiful or not. Generally speaking, if it is artificially leveled, the effect is not good. Very good, fortunately, with the laser leveling machine now, many construction units have also chosen the laser leveling machine for the leveling operation of the road surface, so how does the laser leveling machine have such an excellent leveling effect? 1. Control of the baseline of the laser leveling machine: When the leveling machine is performing automatic leveling, it needs to have an accurate reference plane. Generally, when controlling the height, it is better to use the steel wire; when controlling the thickness, the floating datum beam method is adopted. Generally, the steel wire is used for the bottom layer, and the floating datum beam method is used for the middle layer and the surface layer. The reference wire rope method is to install reference wire ropes on both sides of the road, but note: the distance between the supporting steel bars of the steel wire ropes should not be too large, generally 5-10m; Accurate throughout the construction process. 2. The paving speed control of the laser leveling machine: The leveling machine should work at a constant speed without stopping, and it is strictly forbidden to go fast or slow. During the leveling process, the downtime should be avoided as much as possible, and the daily shutdown interruption should be placed at the position where the contraction joint is scheduled to be made at one end of the structure. In case of shutdown in the middle, the leveling of the leveling machine should be locked to prevent sinking; when the temperature of the mixture is above 100°C, the pause time should not exceed 10 minutes. When the pause time exceeds 30 minutes or the temperature of the mixture is lower than 100°C, To re-seam as for cold seams 3.Laser leveling machine operation control measures: Skilled laser leveling machine operators should be selected and pre-job training should be carried out; during the paving process, the transport truck should stop at 10-30m from the laser leveling machine, put it in neutral, and rely on the laser leveling machine to drive Advance slowly, and there should be a special person to direct the unloading truck to unload; ensure that the feeding system of the leveler has continuity, that is, ensure that the material level in the casters (conveyor wheels) is stable, uniform, and continuous, and the material level is kept high. 2/3 of the blade above the central axis is advisable. Before construction, the leveling must be cleaned. After adjusting the height and slope of the leveling, preheat the leveling. The preheating temperature of the leveling should be close to the temperature of the asphalt mixture, generally it can be heated to 85°C-90°C.
