Prestressed concrete pipe pile structure and construction method
The invention belongs to the technical field of building construction, and discloses a prestressed concrete pipe pile structure and a construction method. The prestressed concrete pipe pile structure comprises a pile end assembly, a first pipe pile section, a second pipe pile section and a third pipe pile section, wherein the pile end assembly, the first pipe pile section, the second pipe pile section and the third pipe pile section are sequentially connected from bottom to top, a first grouting pipe communicates with a second grouting pipe through a corresponding pile side grouting communicating ring, the second grouting pipe communicates with a third grouting pipe through a corresponding pile side grouting communicating ring, and the first grouting pipe communicates with a pile end grouting pipe of the pile end assembly. Slurry injected by grouting equipment from the upper pipe opening of the third grouting pipe can enter the pile end grouting pipe, flow out through a pile end grout overflow hole, enter the pile side grouting communicating ring and flow out through a pile side grout overflow hole, so that the connection stability between the pile end of a prestressed concrete pipe pile and a circumferential soil layer is consolidated, sinking is prevented, the connection stability between the pile side and the circumferential soil layer is consolidated, and the vertical compression resistance bearing capacity, the horizontal load resistance capacity and the uplift bearing capacity of the whole pipe pile structure are improved.
本发明属于建筑施工技术领域，公开一种预应力混凝土管桩结构及施工方法，预应力混凝土管桩结构包括自下而上依次连接的桩端组件、第一管桩段、第二管桩段以及第三管桩段，第一注浆管和第二注浆管之间、以及第二注浆管和第三注浆管之间均通过相应的桩侧注浆连通环连通，第一注浆管与桩端组件的桩端注浆管连通，可使注浆设备从第三注浆管的上管口注入的浆料进入桩端注浆管并通过桩端溢浆孔流出、以及进入桩侧注浆连通环并通过桩侧溢浆孔流出，以巩固预应力混凝土管桩的桩端与周向土层之间的连接稳固性，防止下沉、以及巩固桩侧与周向土层之间的连接稳固性，从而提高整个管桩结构的竖向抗压承载能力、抗水平载荷能力和抗拔承载力。
