What special measures or methods need to be taken to deal with special ground conditions?

For special ground conditions, in order to ensure the construction effect and flatness of the concrete laser leveling, some special measures or methods need to be taken. The following are some common special ground conditions and how to deal with them:
1. Soft soil foundation: For soft soil foundations, foundation reinforcement measures can be taken, such as using geotextiles, drainage materials, etc. to improve the bearing capacity and stability of the ground. In addition, an appropriate amount of early strength agent can be added to the concrete to shorten the initial strength. Set time and improve construction efficiency.
2. Uneven ground: For seriously uneven ground, it can be filled first. Use sand, gravel, filler and other materials to fill potholes and make the ground roughly flat. Then, when the leveler is operating, the pressure and angle of the scraper can be appropriately adjusted to adapt to changes in the ground.
3. Smooth floors: For smooth floors, thickeners, scrubs, etc. can be used to increase the friction coefficient of the concrete to make it better adhere to the ground. At the same time, it is necessary to appropriately adjust the pressure and angle of the scraper and control the slump of the concrete to ensure that the concrete can be spread evenly and reduce slippage.
4. Cross construction: In cross construction sites, the construction work of different professional teams may have a certain impact on the ground. In order to ensure the smoothness of the ground, appropriate plastering and calendering treatments can be carried out before the initial setting of the concrete to eliminate surface marks and uneven areas.
5. Temperature influence: When constructing in high or low temperature environments, attention needs to be paid to controlling the temperature and setting time of concrete. At high temperatures, measures such as sprinkling water to cool down and using retarders can be taken; at low temperatures, measures such as insulation and antifreeze can be taken to ensure the normal hardening of the concrete and the smoothness of the ground.
6. Drainage issues: For floors that are prone to water accumulation, special attention needs to be paid to drainage issues. Drainage materials and drainage ditches can be laid under the concrete cushion to prevent water accumulation from causing adverse effects on the ground.
7. Strengthen edge processing: In the edges or detailed areas, because the leveling machine is difficult to reach or it is difficult to scrape, manual auxiliary processing needs to be strengthened. Manual adjustments can be made using tools such as scrapers and knives to ensure smoothness of edges and detailed areas.
To sum up, for special ground conditions, corresponding special measures or methods need to be taken. These methods can be selected and applied according to the actual situation to achieve the best construction effect and smoothness. It should be noted that in actual stinging, it is necessary to flexibly apply it according to specific conditions, comprehensively consider multiple factors, and formulate reasonable construction plans and quality control measures.
