Stiff composite pile
The invention discloses a stiff composite pile, and relates to the technical field of composite piles, the stiff composite pile comprises a prestressed pipe pile and a concrete pile, the side wall of the prestressed pipe pile is provided with a plurality of first through holes, each first through hole is internally provided with an extension pipe, and the interior of each extension pipe is slidably connected with a moving block; a limiting rod is mounted at one end, far away from the axis of the prestressed pipe pile, of the moving block; a driving assembly used for driving the multiple moving blocks to move towards the outside of the first through hole is installed in the prestressed pipe pile, and a first reset piece used for enabling the moving blocks to reset is installed in the extension pipe. The connection strength between the pile foundation and the inner wall of the pile pit can be improved.
本申请公开了一种劲性复合桩，涉及复合桩的技术领域，其包括预应力管桩以及混凝土桩，所述预应力管桩的侧壁开设有多个第一通孔，每个所述第一通孔内安装有延伸管，所述延伸管内滑移连接有移动块，所述移动块远离预应力管桩的轴心线的一端安装有限位杆；所述预应力管桩内安装有用于驱动多个移动块向第一通孔外移动的驱动组件，所述延伸管内安装有用于使移动块复位的第一复位件。本申请能够提高桩基与桩坑内壁之间的连接强度。
