Construction method of upside-down type construction joint
The invention relates to the field of building construction, in particular to a construction method of an inverted hanging type construction joint. Comprising the steps that earth excavation is carried out, earth on the lower portion of a wall is lowered to the position 35 d below a foundation plane to be constructed, and d is the diameter of the wall; river sand backfilling is conducted, specifically, the over-excavation part in the first step is backfilled with river sand, and the position, 120 mm away from the bottom face of the foundation to be poured, of the top face of the river sand is backfilled; the construction method comprises the following steps: mounting a water stop steel plate, mounting a PVC sleeve, pouring a cushion layer, mounting reinforcing steel bars, mounting a template, pouring concrete, removing the template from the concrete, chiseling a construction joint, excavating earth, removing the cushion layer, an extruded sheet and the PVC sleeve at the construction joint after the earth is excavated in place, and chiseling the construction joint to finish one-time construction. According to the construction method of the upside-down hanging type construction joint, the work load can be effectively reduced, the forming quality of the construction joint is ensured, and the waterproof performance of the construction joint and the reinforcing structure is ensured.
本发明涉及建筑施工领域，具体是一种倒挂式的施工缝的建造方法；包括：土方开挖，将墙体下部土方降至欲施工基础面以下35d距离，其中，d为墙体直径；河砂回填，采用河砂将步骤1所述超挖部分进行回填，回填河砂顶面距离欲浇筑基础底面120mm处；止水钢板安装，PVC套管安装，垫层浇筑，钢筋安装，模板安装及混凝土浇筑，混凝土拆模及施工缝凿毛，土方开挖，土方开挖到位后将施工缝处垫层、挤塑板和PVC套管拆除，并对施工缝进行凿毛处理即可完成一次施工。本发明所提出的上述倒挂式的施工缝的建造方法，齐能够有效减少作业工作量，确保施工缝的成形质量、确保了施工缝及加强结构的防水性能。
