Combined supporting structure of large-span foundation pit and construction method of combined supporting structure
The invention discloses a combined supporting structure of a large-span foundation pit and a construction method thereof.The supporting structure is arranged in the foundation pit and comprises a plurality of row piles arranged along the inner edge of the foundation pit, the upper ends of the row piles are connected with top beams, and the top beams are sequentially connected to form a top beam frame structure along the edge of the foundation pit; the middle of each group of crown beams is connected with a plurality of groups of diagonal bracing assemblies, and the lower ends of the diagonal bracing assemblies are obliquely inserted into a foundation pit soil body close to the center of the foundation pit. The supporting structure is formed by combining a row pile support, an angle supporting support and an inclined supporting support, the heavy pressure load can be effectively borne, the requirement for horizontal displacement control of a large-span foundation pit can be met, each support is formed by assembling a plurality of parts, and the site construction steps can be greatly reduced.
本发明公开一种大跨度基坑的组合支护结构及其施工方法，该支护结构设置在基坑中，包括沿所述基坑内边缘设置的若干排桩，在排桩的上端连接冠梁，多组冠梁依次续接构成沿基坑边缘的冠梁框架结构，在每组冠梁的中部均连接多组斜撑组件，斜撑组件的下端斜向插入靠近基坑中心的基坑土体内。本发明的支护结构由排桩支护、角支撑支护和斜撑支护三者组合能够有效承受重压力负载，可满足于大跨度基坑水平位移控制，各个支护采用多部件装配而成，可极大程度的降低现场施工步骤。
