Foundation pit deformation control structure and construction method
The invention relates to the technical field of constructional engineering, in particular to a foundation pit deformation control structure and a construction method. The foundation pit deformation control structure comprises a plurality of supporting structures fixed to the two sides of a foundation pit in a stepped mode; each supporting structure comprises main supporting pieces symmetrically fixed to the two sides of the foundation pit and supporting foundations arranged in the main supporting pieces different from the soil body on the excavation side of the foundation pit; a plurality of auxiliary supporting pieces connected through connecting bases are arranged between the corresponding main supporting pieces; the auxiliary supporting pieces assist in supporting to avoid displacement of the main supporting pieces; and close to an excavation soil body on the inner side of the foundation pit and/or a soil body on the outer side of the foundation pit, the supporting structures are provided with a plurality of drainage pipelines used for draining underground water. According to the foundation pit deformation control structure, the supporting structures are built in sequence in a step type, and the problems that when the foundation pit of the adjacent building in the existing Binjiang area is built, large-range foundation pit dewatering excavation has large influence on the adjacent building, the adjacent building is prone to deformation, cracking and other dangerous conditions, and the safety of the building and personnel is threatened are avoided.
本发明涉及建筑工程技术领域，具体是一种基坑变形控制结构及施工方法，包括若干台阶式固定在基坑两侧的支撑结构，所述支撑结构包括对称固定在基坑两侧的主支撑件，以及设置在主支撑件异于基坑开挖侧土体中的支撑地基，对应主支撑件之间设有若干通过连接座连接的副支撑件，通过副支撑件协助支撑避免主支撑件位移，所述支撑结构靠近基坑内侧挖掘土体和/或基坑外侧土体设有若干用于排出地下水的排水管路，本发明通过台阶式依次修筑支撑结构，避免了现有滨江地区临近建筑物基坑修筑时，大范围基坑降水开挖对临近的建筑影响大，容易引起临近建筑物的变形以及开裂等等危险情况，威胁建筑物以及人员的安全。
