Water-free grouting construction method for fabricated diaphragm wall post-pouring structure
The invention discloses a water-free grouting construction method for an assembly type diaphragm wall post-pouring structure, which comprises the following steps: firstly prefabricating a wall body of a diaphragm wall, respectively mounting air bags vertically arranged along the wall body on two sides of a connecting end of the wall body, forming a post-pouring groove in the connecting end of the wall body, and arranging the post-pouring groove between the two air bags; then the wall bodies are placed into the excavated groove sections, and a set distance is formed between every two adjacent wall bodies placed into the groove sections; then a steel framework is placed between the two adjacent wall bodies, and the two sides of the steel framework are arranged in the two adjacent post-pouring grooves correspondingly; then the air bags are inflated, the air bags expand to seal the gap between the two sides of the connecting ends of the two adjacent wall bodies, then water, sludge and muck in the post-pouring groove are pumped out, and the post-pouring groove is washed; and finally, water in the post-pouring groove is drained, the post-pouring groove is filled with concrete, the poured concrete wraps the steel framework to form reinforced concrete, and the two adjacent wall bodies are fixedly connected. The wall splicing structure has the effect of improving the sealing effect of the wall splicing position.
本申请公开了一种装配式地连墙后浇结构无水注浆施工方法，其先预制地连墙的墙体，墙体的连接端的两侧分别安装有沿墙体竖向设置的气囊，墙体的连接端设有后浇槽，后浇槽设于两个气囊之间；再将墙体放入开挖好的沟槽段中，放入的相邻两扇墙体之间具有设定的距离；然后往相邻两扇墙体之间放入钢骨架，钢骨架的两侧分别设于相邻的两个后浇槽内；之后往气囊中充气，气囊膨胀将相邻两扇墙体的连接端的两侧之间的间隙封闭，再将后浇槽中的水、淤泥、渣土抽出，并对后浇槽进行冲洗；最后抽干后浇槽中的水，往后浇槽内注满混凝土，浇筑的混凝土包裹钢骨架形成钢筋混凝土并固定连接相邻的两扇墙体。本申请具有提高墙体拼接处的密封效果的效果。
