Construction method for underground diaphragm wall to penetrate through underground structure
The invention relates to a construction method for an underground diaphragm wall to penetrate through an underground structure. The construction method comprises the following steps that S1, a road surface at the top of a channel is treated; S2, a water retaining ridge is arranged in the channel, specifically, the water retaining ridge prevents mortar or water for pouring a deep guide wall from overflowing everywhere in the channel; S3, full scaffolds are erected in the channel, specifically, the full scaffolds are erected at the tops of a bottom plate and a middle plate; S4, a top plate and the middle plate in the area of the deep guide wall are removed, specifically, the top plate and the middle plate below a pit are cut by adopting a cutting machine; S5, the deep guide wall is poured, specifically, a1, reinforcing steel bars of the deep guide wall are bound, specifically, the reinforcing steel bars of the deep guide wall are directly bound to the ground position from the position ofthe bottom plate; a2, a deep guide wall formwork is installed; and a3, concrete of the deep guide wall is poured, specifically, the concrete of the deep guide wall is poured and formed in a graded mode; S6, layered backfilling is carried out in the channel, specifically, the top plates on the two sides and the middle of the deep guide wall are broken and backfilled, and layered backfilling and rolling are carried out in the channel; and S7, grooving construction of the underground diaphragm wall is carried out in the deep guide wall. The construction method has the effects of preventing slurry from flowing outwards and preventing the groove wall from collapsing during construction of the underground diaphragm wall.
本申请涉及一种地连墙穿越地下结构物施工方法，包括如下步骤：S1、通道顶部路面处理；S2、通道内设置挡水坎：挡水坎防止浇筑深导墙的砂浆或者水在通道内到处漫流；S3、在通道内搭设满堂脚手架：在底板和中板的顶部搭设满堂脚手架；S4、拆除深导墙区域的顶板和中板：采用切割机对凹坑下方的顶板和中板进行切割；S5、浇筑深导墙：a1、深导墙钢筋绑扎：深导墙钢筋从底板的位置直接绑扎到地面位置；a2、深导墙模板安装；a3、浇筑深导墙的混凝土：深导墙混凝土分次浇筑成型；S6、通道内分层回填：对深导墙两侧的顶板和中部进行破除回填，在通道分层回填碾压；S7、在深导墙内进行地连墙成槽施工。本申请具有防止地连墙施工时泥浆外流和槽壁坍塌的效果。
