Trenchless pipe jacking and dragging foundation pit supporting structure and construction method
The invention relates to the field of foundation pit supporting, and particularly discloses a foundation pit supporting structure of a trenchless pipe jacking and dragging pipe and a construction method.The foundation pit supporting structure comprises a Larsen steel sheet pile and two end pulling groove piles connected to the Larsen steel sheet pile in a buckled mode, and the end pulling groove piles are located on the two sides of a pipe opening; an end opening plate and a plurality of shaping plates are detachably arranged between the two end pulling groove piles, and the end opening plate and the shaping plates jointly form a soil retaining surface used for stabilizing a soil body; the port plate is provided with a through hole for a pipeline to penetrate through, and a lock cover is detachably connected to the port plate and used for closing or opening the through hole. While the pipe orifice is sealed, a pipe orifice soil body is supported and reinforced, a stable pushing rear seat face can be provided, the pipe orifice sealing device is suitable for pipe jacking and pipe dragging construction, components used for construction can be recycled, and the construction cost can be saved.
本申请涉及基坑支护领域，具体公开了一种非开挖顶管、拖拉管的基坑支护结构及施工方法，基坑支护结构包括拉森钢板桩和扣接于拉森钢板桩的两个端拉槽桩，端拉槽桩位于管口的两侧；两个端拉槽桩之间可拆卸地设置有端口板和多个定型板，端口板和多个定型板共同组成用于稳定土体的挡土面；端口板上开设有供管道穿过的通孔，端口板上可拆卸地连接有锁盖，用于封闭或打开通孔。本申请在对管口进行封闭的同时，对管口土体进行支护加固，可以提供稳固的顶推后座面，对于顶管和拖拉管施工均可适用，且施工使用的构件均可回收利用，有利于节约施工成本。
