Post-grouting construction method for wall side of ultra-deep fabricated diaphragm wall
The invention relates to a wall side post-grouting construction method for an ultra-deep fabricated underground diaphragm wall, which is characterized in that a plurality of guide rails are vertically arranged on the side wall of a foundation groove of the underground diaphragm wall, grouting holes are formed in the guide rails, and underground diaphragm wall precast blocks are lowered along the guide rails, so that the lowering and mounting precision of precast underground diaphragm wall sections can be ensured; the grouting pipes are inserted into the grouting holes in the guide rails to conduct grouting on the broken stone filling between the underground diaphragm wall and the foundation trench, no grouting hole is formed in the underground diaphragm wall precast block, the strength of the underground diaphragm wall precast block can be guaranteed, the steel guide rails and the underground diaphragm wall are combined into a whole after grouting, a permanent structure of the underground diaphragm wall is formed, and the shear capacity of the underground diaphragm wall can be enhanced.
本发明涉及一种超深装配式地连墙墙侧后注浆施工方法，在地连墙基槽侧壁上竖向设置多根导轨，并在导轨上设置注浆孔，地连墙预制块沿导轨下放，可保证预制地连墙节段的下放及安装精度，通过导轨上的注浆孔插入注浆管向地连墙与基槽间的碎石填充内注浆，地连墙预制块上不再设置注浆孔，能保证地连墙预制块的强度，注浆后钢导轨与地连墙结合为一体，成为地连墙的永久结构，可增强地连墙的抗剪能力。
