Underground wall post-cast strip formwork reinforcing and mounting construction method
The invention discloses an underground wall post-cast strip formwork reinforcing and mounting construction method, and relates to the technical field of underground wall post-cast strip formwork construction. Reserved tie bars are arranged on the surface of the concrete outer wall protection plate, one sides of the reserved tie bars are tightly attached to the outer wall of the post-cast strip, the tie bars are located in the post-cast strip wall body, waterproof mortar is adopted for leveling and tightly blocking a gap between the outer wall protection plate and the post-cast strip wall body, and earthwork is backfilled in time after an anti-corrosion waterproof layer is made. The post-cast strip inner wall formwork opposite-pull screw is welded to an outer wall concrete protection plate reserved tie bar, and the other end of the post-cast strip inner wall formwork opposite-pull screw is fastened through a dovetail clamp matched with a steel pipe nut. And the opposite-pull screw rods exposed out of the original wall bodies on the two sides of the post-cast strip are used as back arris locking devices of the formwork on the inner side of the post-cast strip, the number of the opposite-pull screw rods in the post-cast strip wall bodies is reduced, water seepage and leakage channels of the wall bodies are reduced, the double reinforcing effect is achieved, and meanwhile the appearance forming quality of concrete is improved.
本发明公开了一种地下墙体后浇带模板加固及安装施工方法，涉及地下墙体后浇带模板施工技术领域。本发明在混凝土外墙保护板表面设置预留拉筋，将预留拉筋一侧紧贴后浇带外墙壁，使其拉筋位于后浇带墙体内，采用防水砂浆将外墙保护板与后浇带墙体之间缝隙找平堵严，做好防腐防水层后及时回填土方。后浇带内壁模板对拉螺杆与外墙混凝土保护板预留拉筋焊接，另一端采用燕尾卡配合钢管螺母紧固。再利用后浇带两侧原来墙体外露的对拉螺杆作为后浇带内侧模板背楞锁紧装置，减少了后浇带墙体内自身对拉螺栓杆数量，减少了墙体渗水漏水渠道，起到双重加固作用，同时提升了混凝土外观成型质量。
