Background

In the construction of urban construction pile foundation engineering, most building foundation forms adopt reinforced concrete drilled steel pipe columns. Namely, firstly, a drilling machine is adopted to drill holes on the ground, and prepared bentonite slurry is injected into the drilled pile holes, so that the hole wall collapse of the pile holes can be effectively prevented. After the pile hole reaches the designed pile bottom elevation, a reinforcing cage is hung and installed in the pile hole filled with bentonite slurry, then a pouring guide pipe is installed, and concrete is poured into the hole bottom, so that the reinforced concrete steel pipe column is formed. As the pile top of the common steel pipe column is positioned 10-20m below the ground, after concrete is poured to the designed pile top elevation, the flowing slurry with the depth of 10-20m is still in the upper pile hole. The lower part is a section of a steel pipe column formed by filling a steel reinforcement cage and concrete, and is an effective pile section; the area of the pile bore without reinforced concrete in the upper part is usually called empty pile section, which is generally filled with fluid bentonite slurry. The pile diameter of a common steel pipe column is larger and is between 1.5 and 3.0m, and if the bentonite slurry in the pile holes after concrete pouring is not treated, pile holes filled with the bentonite slurry are formed in a construction site. The depth of the bentonite slurry in the pile hole is 10-20m, so that potential safety hazards are formed, mechanical equipment on a construction site cannot walk, or the mechanical equipment is turned over or toppled.

For the pile holes filled with the bentonite slurry, currently, researchers cure the bentonite slurry of the hollow pile section by using cement, but the cement has a high mixing amount due to insufficient reaction effect of the cement and the fine-particle bentonite slurry, the strength after the bentonite slurry is reinforced is low, the curing reaction is slow, and the large-area popularization and application are not facilitated. Therefore, based on the current engineering situation, the curing agent is added into the bentonite slurry of the hollow pile section in the pile hole at present, the curing agent and the bentonite slurry mainly containing fine particles have sufficient physical and chemical reactions, the mixing amount of the curing agent is less, the strength after the bentonite slurry is cured is higher, and the curing reaction speed is high, but at present, the problem of pipeline blockage is often caused due to the existence of coarse particles in the curing agent.
