Ramp foundation pit plate supporting and reverse construction combined supporting structure and construction method thereof
The invention discloses a ramp foundation pit plate support combined reverse construction supporting structure and a construction method thereof, which comprises an underground diaphragm wall, a middle plate, a cast-in-place pile, a latticed column, a ramp top plate and a ramp bottom plate, and is characterized in that the middle plate is positioned at the junction of the upper part of a ramp deep pit along the height direction and the lower part of a ramp shallow pit along the height direction; the two ends of the middle plate are fixedly connected with the cast-in-place piles through the ramp deep pit top ring beams, the ramp shallow pit top ring beams are fixedly installed on the top of the underground diaphragm wall in the height direction, the middle plate and the ramp bottom plate are poured into a whole, and the middle plate is fixedly connected with the ramp top plate through the latticed columns. According to the middle plate reverse construction method, the middle plate reverse construction method is adopted, construction of a first support of a deep pit can be reduced, meanwhile, the procedure of dismantling the support during main body construction is avoided, the construction cost is saved, the construction period is shortened, and the middle plate reverse construction method has high popularization value.
本发明公开了一种匝道基坑板撑结合逆做支撑结构及其施工方法，包括地下连续墙、中板、灌注桩、格构柱、匝道顶板、匝道底板，其特征在于，中板位于匝道深坑沿高度方向上部与匝道浅坑沿高度方向下部的交界处，中板的两端通过匝道深坑顶圈梁与灌注桩固定连接，地下连续墙沿高度方向的顶部固定安装有匝道浅坑顶圈梁，中板与匝道底板浇筑成为一体，中板通过格构柱与匝道顶板固定连接，且格构柱沿高度方向相对于匝道顶板向外延伸并与匝道浅坑顶圈梁固定连接，本发明采用中板逆做法，可以减少深坑第一道支撑的施工，同时避免了在主体施工时拆除支撑的工序，节约施工成本，且减少了施工工期，具有较高的推广价值。
