Prestressed pipe pile and pile sinking method
The invention discloses a prestressed pipe pile and a pile sinking method.The prestressed pipe pile comprises a pipe pile body, a steel plate, a grouting steel pipe, an auxiliary positioning plate and a grouting head, the steel plate is fixed to the lower end of the pipe pile body, the grouting head is arranged at the bottom of the steel plate, a vertical threaded hole is formed in the center of the upper portion of the steel plate, and the threaded hole communicates with the grouting head; the auxiliary positioning plates are circular plates with connecting holes in the centers, the multiple auxiliary positioning plates are distributed on the periphery of the grouting steel pipe from top to bottom, the grouting steel pipe is rotationally connected with the connecting holes and penetrates into the pipe pile body from top to bottom, the lower end of the grouting steel pipe is in threaded connection with the threaded holes, and the outer contours of the auxiliary positioning plates are attached to the inner wall of the pipe pile body. The problem that it is difficult for the prestressed pipe pile to penetrate through a sand layer can be effectively solved, the construction period is short, the grouting steel pipe can be recycled, disassembly and assembly are convenient and easy, and installation is stable.
本发明公开了一种预应力管桩及沉桩方法，其中预应力管桩包括：管桩主体、钢板、注浆钢管、辅助定位板和注浆头，管桩主体的下端固定有钢板，钢板的底部设置有注浆头，钢板的上方中心设置有竖直的螺纹孔，螺纹孔连通注浆头，辅助定位板为中心带有连接孔的圆形板，注浆钢管的外周由上至下分布有多个辅助定位板，注浆钢管与连接孔转动连接，注浆钢管由上至下穿于管桩主体内，且注浆钢管的下端螺纹连接于螺纹孔，辅助定位板的外轮廓贴于管桩主体的内壁；该能有效解决预应力管桩穿越砂层困难的问题，施工周期短，且注浆钢管能进行回收利用，拆装方便简单，安装稳固。
