Foundation pit support of super high-rise and ultra-deep foundation pit adjacent to subway and construction method of foundation pit support
The invention discloses a foundation pit support of a super high-rise and ultra-deep foundation pit adjacent to a subway and a construction method of the foundation pit support. An underground diaphragm wall and a floor slab are connected through pre-buried joint bars. The underground diaphragm wall and a raft board foundation are connected in a matched manner through pre-buried joint bars and anchor bars. Due to the super high-rise property, reinforcing steel bars of a raft board are thick and not likely to be straightened, the raft board reinforcing steel bars and the anchor bars are connected through connectors, and site construction is facilitated. The underground diaphragm wall is used as a basement external wall, is high in stability and can meet the firmness degree of the structure,existing work of inner support detachment and the like is omitted, the construction period is greatly shortened, and manpower and material resources are saved; before construction, feasibility of thestructure stability can be ensured through simulation, and on the basis of ensuring safety, the construction period is short, and manpower and material resources are saved; and compared with a current construction method, outstanding progresses are made.
本发明公开了一种紧邻地铁超高层超深基坑的基坑支护及其施工方法，地连墙与楼板之间采用预埋插筋连接，地连墙与筏板基础之间采用预埋插筋与锚筋同配合连接，并且由于是超高层，所以筏板的钢筋比较粗，不容易调直，所以采用接驳器将筏板钢筋与锚筋连接，便于现场施工。将地连墙作为地下室外墙，稳定性强，能够满足结构的牢固程度，省去了以往内支撑的拆除等工作，大大缩短了施工工期，节省了人力物力，并且在施工前还可以通过模拟确保结构稳定的可行性，保证安全性的基础上，实现了施工工期短，节省了人力物力，与目前的施工方法相比，具有突出的进步。
