Pore pressure counterforce steel pipe pile pulling method and pipe pulling device thereof
The invention relates to a pore pressure counterforce steel pipe pile pulling method and a pipe pulling device thereof in the foundation pit support and pile foundation engineering field in the geotechnical engineering field. The pile pulling method comprises the steps of forming a fluid storage chamber (9) in a steel pipe pile (1) by using a side wall of the steel pipe pile (1), a sealing pipe plug (3) and a steel pipe pile inner soil mass (2), increasing pressure of gas or liquid in the fluid storage chamber (9) by continuously filling gas or liquid into the fluid storage chamber (9); increasing pore water pressure or pore gas pressure of the steel pipe pile inner soil mass (2); transferring the pore water pressure or pore gas pressure to the sealing pipe plug (3) to produce pile pulling force or be used as part of the pile pulling force to perform pulling construction of the steel pipe pile (1). The method can also be used for uplift bearing capacity tests of the steel pipe pile (1), the pile pulling equipment is small, the manufacturing cost is low and the problem of influence of soil disturbance on surrounding environments during pile pulling can be solved.
