Construction method of deep foundation pit steel sheet pile and anchor cable supporting system
The invention discloses a construction method for a deep foundation pit steel sheet pile and anchor cable supporting system, and belongs to the field of deep foundation pit supporting. The construction method comprises the following construction steps that S1, a site is leveled, and positioning and paying-off are conducted; S2, a guide ditch is excavated, and a fence support is built; S3, connecting pieces are sequentially driven into a soil layer; S4, steel sheet piles are sequentially driven into the soil layer according to the positions of the connecting pieces; S5, a steel crown beam is mounted at the top of each steel sheet pile; S6, earth excavation is conducted in a layered mode, and after excavation is conducted to the designed depth, anchor cable construction is conducted through the connecting pieces; and S7, the adjacent steel sheet piles are fixed through the connecting beams, and overall stress of the steel sheet piles is guaranteed. Each connecting piece comprises a positioning plate and a mounting plate fixedly connected to the positioning plate, and a mounting groove used for being matched with a locking opening of the steel sheet pile in an inserted mode is formed in the mounting plate. The method has the effect of conveniently recycling steel sheet piles.
本申请公开了深基坑钢板桩加锚索支护体系施工方法，属于深基坑支护的领域，其以下施工步骤：S1、平整场地，并定位放线；S2、开挖导向沟并建立围挡支护；S3、依次将连接件打入土层；S4、依据连接件的位置依次将钢板桩打入土层；S5、在钢板桩的顶部安装钢冠梁；S6、分层进行土方开挖，当开挖至设计深度后，利用连接件进行锚索施工；S7、利用连接梁固定相邻的钢板桩，保证钢板桩的整体受力；所述连接件包括定位板以及固定连接于所述定位板上的安装板，所述安装板上开设有用于与所述钢板桩的锁口插接配合的安装槽。本申请具有方便回收钢板桩的效果。
