Deep foundation pit supporting system and construction method
The invention belongs to the technical field of foundation pit supporting, and particularly relates to a deep foundation pit supporting system which comprises two rows of batter piles, a top beam, end anchoring inner supports, prestressed anchor rods and inter-pile reinforcing soil, the two rows of batter piles comprise prefabricated open-web bamboo joint piles and prefabricated rectangular piles, waist beams are fixed to the prefabricated rectangular piles, the top beam is arranged at the tops of the batter piles, and the end anchoring inner supports are fixed to the end anchoring inner supports. A horizontal inner support is arranged on the top beam, splayed support structures are arranged at the two ends of each end anchoring inner support, the end anchoring inner supports and the splayed supports are fixed to the waist beam, anchoring supports are arranged at the ends of the end anchoring inner supports and the splayed supports, the pre-stressed anchor rods are anchored to the anchoring supports, and the inter-pile reinforcing soil is located between the two rows of inclined piles. The inclined piles, the top beams, the pre-stressed anchor rods and the reinforcing soil between the piles form a triangular row pile supporting system, the triangular row pile supporting system is combined with the end anchoring inner supports, the axial force of the inner supports can be effectively transferred and counteracted, and the purpose of reducing the using number of the inner supports can be achieved while the deep foundation deformation control requirement is met.
本发明属于基坑支护技术领域，具体地涉及一种深基坑支护体系，包括两排斜桩、冠梁、端部锚固内支撑、预应力锚杆和桩间加固土，两排斜桩包括预制空腹竹节桩和预制矩形桩，预制矩形桩上固定有腰梁，冠梁设置在斜桩的顶部，冠梁上设有水平内支撑，端部锚固内支撑的两端均设置有八字撑结构，端部锚固内支撑和八字撑均固定在腰梁上，端部锚固内支撑和八字撑的的端部均设有锚固支座，预应力锚杆锚固在锚固支座上，桩间加固土位于两排斜桩之间。本发明通过斜桩、冠梁、预应力锚杆和桩间加固土构成三角形排桩支护体系结合端部锚固内支撑，可有效转移和抵消内支撑的轴力，在满足深基变形控制要求的同时，还能达到减少内置撑使用数量的目的。
