Early closing structure for retaining wall post-cast strip and construction method
The invention relates to a retaining wall post-cast strip advanced closing structure and a construction method, the structure comprises a steel plate located on a soil facing surface and a tool type induction template located on a soil backing surface, the thickness of the steel plate is larger than or equal to 5 mm, and the width of the steel plate and the width of the tool type induction template are both larger than the width of a post-cast strip. Water stop screws are evenly distributed and connected to the sides, located on the post-cast strip, of the steel plates, the water stop screws are detachably connected with tool type induction formworks, the steel plates and the tool type induction formworks are fixed to the two opposite faces of the post-cast strip through the water stop screws, and the two sides of the steel plates and the two sides of the tool type induction formworks are in lap joint with the wall faces of the corresponding poured retaining walls correspondingly. And the tool type induction template can be used for forming an induction joint in the post-cast strip. The rigidity, the stability and the bearing capacity of the steel plates are utilized, earth facing face earthwork is backfilled in advance, the construction rhythm is accelerated, the efficiency is improved, meanwhile, the steel plates serve as formworks, the pouring quality of the post-pouring belt is ensured, and stress release of the retaining wall and differential settlement of a main building podium building can be effectively controlled through the induction joints.
本发明关于一种挡土墙后浇带提前封闭结构及施工方法，该结构包括位于临土面的钢板和位于背土面的工具式诱导模板，钢板厚度大于或者等于5mm，钢板的宽度和工具式诱导模板的宽度均大于后浇带的宽度，钢板位于后浇带的一侧均布连接有止水螺杆，止水螺杆可拆卸连接工具式诱导模板，钢板和工具式诱导模板通过止水螺杆固定在后浇带的相对的两面，钢板的两侧和工具式诱导模板的两侧分别搭接于对应的已浇筑挡土墙的墙面，工具式诱导模板能够在后浇带中成型诱导缝。本发明利用钢板的刚度、稳定性及承载力，使临土面土方提前回填，加快施工节奏，提升效率，同时钢板作为模板，确保后浇带浇筑质量，诱导缝可有效控制挡土墙应力释放以及主楼裙楼的不均匀沉降。
