Ultra-long structure concrete construction method combining warehouse jumping and flowing water recursion
The invention relates to a super-long structure concrete construction method combining warehouse jumping and flowing water recursion, which comprises the following steps of: A, dividing warehouse blocks, dividing the warehouse blocks on a top plate, an outer wall and a bottom plate along the longitudinal direction and the transverse direction, and arranging construction joints between the warehouse blocks; b, the construction sequence is determined, construction is conducted in each area through a flowing water recursion method, flowing water recursion construction pouring is conducted from one side to the other side, a warehouse jumping method is adopted between warehouse blocks, and the construction interval time of every two adjacent warehouse blocks is 7 days or above; c, a layered material distribution, layered vibration and slope propelling method is adopted for concrete pouring; d, concrete curing is conducted, specifically, after concrete bottom plate and top plate pouring is completed, spraying curing is conducted in the initial setting period, and then a plastic film is used for covering; and paving a long pipe on the top of the wall for watering or spraying at any time. According to the construction method, the warehouse jumping method and the running water recursion method are combined, shrinkage joints of concrete are reduced, the construction joints are used for replacing an original post-cast strip, water leakage and water and soil loss caused by arrangement of the post-cast strip are avoided, the process is simple, and the construction period is short.
本发明涉及一种跳仓与流水递推相结合的超长结构混凝土施工方法，包括A、仓块划分，在顶板和外墙、底板上沿纵向和横向分仓，在仓块与仓块之间设置施工缝；B、确定施工顺序，每个区域内以流水递推的方法进行施工，从一侧向另一侧流水递推施工浇筑，仓块与仓块之间采用跳仓法，相邻仓块施工的间隔时间7天以上；C、混凝土浇筑采用分层布料、分层振捣、斜坡推进法；D、混凝土养护，混凝土底板、顶板浇筑完毕，在初凝期进行喷雾养护，后用塑料薄膜覆盖；混凝土养护，墙顶铺长管随时浇水或喷雾。跳仓与流水递推的方法相结合，减少混凝土的收缩缝，使用施工缝代替原来的后浇带，避免了因留设后浇带带来的漏水以及水土流失，工艺简单，工期短。
