Research and practice of JZGZ pile foundation

Traditionally, the prestressed pipe pile is constructed by the static pressure method or the hammering method, but the soil arching effect caused by these two methods will adversely affect the quality and security of the engineering project. JZGZ pile foundation, implanting the pipe pile after grouting cement slurry into the pre-bored hole, solves the soil arching effect effectively, improves the lateral friction of the pipe pile foundation, and increases the root resistance by enlarging the scale of the root of the pile foundation. The construction process of the JZGZ pile foundation, vertical compressive bearing capacity in the design and engineering application are introduced.
