Description

Technical Field

[0002] With the rapid development of urban construction and transportation engineering, the development and utilization of underground space has become a trend, and the construction technology level has also put forward higher requirements. The buoyancy generated by groundwater has a particularly prominent impact on underground structures. When the underground water level of the underground structure of the construction project is high, anti-floating measures need to be adopted. Anti-floating measures are generally solved by anti-floating pipe pile technology. As a type of pile foundation, anti-floating pipe piles are increasingly valued by the engineering community. The anti-floating force generated by anti-floating pipe piles is used to offset the buoyancy generated by groundwater on underground structures. When the building adopts the anti-floating pipe pile design, it is necessary to pour concrete in the pipe piles and leave anti-floating steel bars in the concrete to anchor them in the basement floor structure. Since the inner wall of the pipe pile is very smooth, it has an adverse effect on the joint bite between the post-poured concrete and the pipe wall. It is often necessary to increase the pouring height. In order to ensure reliable bonding between the post-poured concrete and the inner wall of the pipe, a pipe pile roughening treatment equipment is required to clean the inner wall of the pipe to meet the requirements of the pipe pile construction design.
