Deep and large raft foundation post-cast strip formwork system and foundation construction method
The invention belongs to the technical field of house building foundation construction, and particularly relates to a deep and large raft foundation post-cast strip formwork system and a foundation construction method. The deep and large raft foundation post-cast strip formwork system comprises formworks and a post-cast strip supporting frame, wherein the formworks are located on the two sides of a post-cast strip, and the post-cast strip supporting frame is supported between the two formworks; the post-cast strip supporting frame is of a steel structure; and the formworks are steel wire net frames, a layer of water stop steel plate is arranged on the formworks in the length direction of the formworks to prevent water from permeating from a construction joint from bottom to top, the water stop steel plate is of an inverted-U-shaped structure, the center line of the water stop steel plate coincides with the construction joint, one half of the water stop steel plate is located in the post-cast strip, the other half of the water stop steel plate is located in a pre-cast concrete area, and the water stop steel plate is arranged in the 1/2 position of the thickness of a raft plate. According to the deep and large raft foundation post-cast strip formwork system, the construction process is simplified while the construction quality is guaranteed, and the construction cost and the construction difficulty are reduced.
本发明属于房建基础施工技术领域,具体涉及一种深大筏板基础后浇带模架体系及基础施工方法。本发明包括位于后浇带两侧的模板和支撑在两个模板之间的后浇带支撑架;所述后浇带支撑架为钢结构;所述模板为钢丝网架,模板上沿其长度方向设有一层止水钢板,防止水从施工缝自下至上渗透,止水钢板为倒U形结构,止水钢板的中心线与施工缝重合,止水钢板的一半位于后浇带内、另一半位于先浇混凝土区内,止水钢板设于筏板板厚度的1/2处。本发明保证施工质量的同时简化施工工序,降低施工成本和施工难度。
