Prefabricated pipe pile support temporary drainage device and construction method thereof
The invention provides a prefabricated pipe pile supporting temporary drainage device and a construction method thereof, and belongs to the technical field of foundation pit supporting, the device comprises a gap filling device and prefabricated pipe pile units, and the gap filling device is arranged between the adjacent prefabricated pipe pile units; the gap filling device comprises pipe fittings, a jacking plate and gaskets, the multiple pipe fittings and the multiple gaskets are arranged between the adjacent prefabricated pipe pile units in a staggered mode, and the two ends of the jacking plate are connected with the prefabricated pipe pile units; gaskets and pipe fittings are arranged between the prefabricated pipe pile units, and the gaskets are used for adjusting and compacting the distance between the pipe fittings or between the pipe fittings and the prefabricated pipe pile units, so that water of the foundation pit is prevented from permeating into the side wall of the foundation pit, and piping caused by water and soil loss due to channels formed between the pipe fittings is prevented; according to the method, the positions of the drainage holes and the prefabricated pipe pile embedded plate are arranged in a staggered mode, and the situation that due to the fact that the prefabricated pipe pile embedded plate is provided with surrounding purlins and top braces, stress on the prefabricated pipe pile embedded plate is large, and stress concentration is generated is avoided.
本发明提供了一种预制管桩支护临时排水装置及其施工方法，属于基坑支护技术领域，装置包括间隙填补装置和预制管桩单元，间隙填补装置设置在相邻的预制管桩单元之间；间隙填补装置包括管件、顶撑板和垫片，多个管件和多个垫片交错设置在相邻的预制管桩单元之间，顶撑板的两端与预制管桩单元连接；在预制管桩单元之间设置垫片和管件，利用垫片对管件间或者管件与预制管桩单元间进行间距调整和挤密，从而防止基坑的水渗入基坑侧壁和防止管件间形成通道造成水土流失发生管涌；本方法将排水孔的位置与预制管桩预埋板错开设置，防止由于预制管桩预埋板处有围檩和顶撑存在，预制管桩预埋板处受力较大，产生应力集中。
