Raft type pit bottom horizontal brace and construction method
According to the raft type pit bottom horizontal brace and the construction method, basin type excavation is adopted, earthwork in the middle of a foundation pit is excavated to the designed elevation, the periphery of the foundation pit is sloped, and after a cushion layer in the middle of the foundation pit is poured, earthwork of the periphery slope is excavated in a sectional mode, and the raft type pit bottom horizontal brace is constructed in a sectional mode; and inclined stabilizing rods or vertical stabilizing rods are installed, a concrete cushion layer is poured, and the raft type pit bottom horizontal brace is formed. Compared with an existing cast-in-place concrete support, the technology disclosed by the invention has the advantages that the cost can be reduced, the construction period is shortened, construction is convenient, and remarkable economic benefits and social benefits are achieved.
本发明涉及的排筏式坑底平撑及施工方法，采用采用盆式开挖，先开挖基坑中部的土方到设计标高，基坑四周放坡，基坑中部的垫层浇筑完成后，再分段式开挖周边放坡的土方，分段式施工排筏式坑底平撑：安装纵向单撑和稳定檩，安装斜稳杆或竖稳杆，浇筑混凝土垫层，形成排筏式坑底平撑。本发明公开的技术，相比于现有的现浇混凝土支撑，可以降低成本、减少工期、方便施工，具有显著的经济效益和社会效益。
