The drilling of construction sites requires the use of drill bits. When using the drill bit, it will encounter the phenomenon of stuck or dropped drills, which brings certain danger to the construction workers. The use of polyacrylamide can play a role in lubricating the drill bit to reduce friction, so as to avoid the use. Danger of drilling. At the same time, during the piling of construction sites, the soil in the underground soil layer will be large, causing the soil wall to be loose and easy to fall off, which brings construction instability. At the same time, the mixing of construction water and groundwater also causes drainage difficulties and increases the looseness of the soil. If it is treated by air drying, the construction cost and construction difficulty are increased, and the construction time is extended to some extent. Polyacrylamide can be used as The plugging agent and fluid loss reducer reduce the penetration of moisture and avoid further shedding of the soil layer. Polyacrylamide has thickening and adhesion, and it is the adhesion of the soil to inhibit the looseness of the layer.
The use of polyacrylamide in construction site piling has reduced the safety hazards of construction to a certain extent, reduced the cost of piling and improved the efficiency of piling.
