Middle partition wall bottom plate support changing structure for foundation pit separate construction
The invention relates to a bottom plate support changing structure, belongs to the technical field of foundation pit construction, and particularly relates to a middle partition wall bottom plate support changing structure for foundation pit separate construction, which comprises a middle partition wall, horizontal structures are poured on the two sides of the top end of the middle partition wall, and bottom plate structures are poured on the tops of the two horizontal structures. The sides, close to each other, of the two bottom plate structures are jointly provided with a post-cast strip groove. According to the construction method, when foundation pits on the two sides of the middle partition wall are excavated to the bottom and the bottom plate structure is constructed, the junction of a bottom plate and the middle partition wall is vacated by the width of 500 mm, the bottom plate structure reserves joint bars with enough number and interval, and the joint bars are provided with construction joints through steel wire meshes. A slope of 500 mm is arranged below the junction of the bottom plate and the middle partition wall within the range of 1000 mm, a slope of 45 degrees is formed, reinforcing steel bars and bottom plate structural reinforcing steel bars are arranged in the junction of the bottom plate and the middle partition wall, the bottom plate structure is anchored to bottom plate surface ribs, the safe, economical and reasonable dismantling construction process of the middle partition wall 1 is achieved, and the problem that due to the fact that the bottom plate is not closed in an unpoured area, the sudden gushing risk exists is solved.
本发明涉及一种底板换撑结构，属于基坑施工技术领域，具体是一种基坑分坑施工的中隔墙底板换撑结构，包括中隔墙，所述中隔墙的顶端两侧均浇筑有卧式结构，两个卧式结构的顶部均浇筑有底板结构，两个底板结构相互靠近的一侧共同设有后浇带槽；本发明通过在中隔墙两侧基坑开挖至底部后并进行底板结构施工时，在底板与中隔墙交界处空出500mm宽度，底板结构预留足够数量与间距的插筋，此处通过钢丝网设置施工缝。底板与中隔墙交界处1000mm范围内下卧500mm并作45°斜坡，内部配置钢筋同底板结构钢筋，并锚入底板结构至底板面筋处，实现了中隔墙1拆除施工过程安全、经济、合理，解决了未浇筑区域因底板未封闭，存在突涌风险的问题。
