Prestressed concrete pipe pile and pile sinking method thereof
The invention discloses a prestressed concrete pipe pile and a pile sinking method thereof. The prestressed concrete pipe pile comprises a pipe pile body with an internal hole, a pile tip for blockingthe end part of the internal hole is connected to one end of the pipe pile body, the pile tip comprises a base plate connected to the pipe pile body and a plurality of sharp teeth arranged on the base plate, and the multiple sharp teeth are uniformly arranged around the central line of the internal hole at intervals. The advantages that the structure is simple, manufacturing is easy, the cost islow, the weight is less, installation is easy, and quick, stable and safe pile sinking is facilitated are achieved. The pile sinking method comprises the steps that drilling equipment is adopted to drill a lead hole at a preset pile sinking point in a collapsible area, then the pipe pile body is sunk into the drilled lead hole by a pile machine, and the advantage that the stability of pile sinkingand the pile sinking rate can be improved is achieved.
本发明公开了一种预应力混凝土管桩及其沉桩方法，预应力混凝土管桩包括具有内孔的管桩本体，管桩本体的一端连接有封堵住内孔端部的桩尖，桩尖包括连接于管桩本体上的基板和设于基板上的多个尖齿，多个尖齿绕内孔的中心线均匀间隔布置，具有结构简单、易于制作、成本低、重量轻、易于安装、利于快速、稳定、安全沉桩的优点。沉桩方法是在湿陷性地区先采用钻孔设备在预设的沉桩点钻出引孔，再采用桩机将管桩本体沉入钻出的引孔中，具有可提高沉桩稳定性和沉桩率的优点。
