Backfill reverse construction method for basement cantilever slab
The invention discloses a backfill reverse construction method for a basement cantilever slab. The backfill reverse construction method comprises the following step that 1, a basement outer wall main body structure is constructed, a cantilever structure part structure is not constructed temporarily in the construction stage of a main building structure, independent concrete outside an outer wall is constructed to the beam bottom elevation, a part of beam slabs of the main building structure extend out by 30cm, and steel bar joints are reserved. According to the backfill reverse construction method for the basement cantilever slab, a basement cantilever slab reverse construction method is adopted for construction, the problems that the waterproof effect of a cantilever part in a basement, the backfill soil compaction effect, the influence of synchronous settlement of cantilever part filling soil and a main building foundation on a foundation and the like are solved, and the engineering construction quality is guaranteed; and compared with normal construction, due to the fact that construction of other parts is normally carried out, the total construction period is shortened by 32 days, the mechanical and formwork rental cost is correspondingly reduced, in addition, the investment of supports and formworks of the cantilever slab is reduced, the engineering cost is reduced, good benefits are obtained, and the backfill reverse construction method is worthy of being used for reference in similar engineering.
本发明公开了一种地下室悬挑板回填逆作施工方法，包括如下步骤：步骤一：地下室外墙主体结构施工，主楼结构施工阶段悬挑结构部位结构暂时不施工，外墙外独立的混凝土施工至梁底标高，主楼结构部分梁板伸出30cm，预留好钢筋接头，此一种地下室悬挑板回填逆作施工方法采用地下室悬挑板逆作法施工，不仅解决了悬挑部位在地下室的防水、回填土密实、悬挑部位填土与主楼基础同步沉降对地基的影响等问题，保证了工程施工质量，而且与正常施工相比，由于其他部位施工的正常进行，从而缩短了总施工工期32天，机械和模板租赁费相应减少，另外还少投入了悬挑板的支架和模板，降低了工程成本，取得较好的效益，值得在类似工程上借鉴使用。
