Rear anchor type rigid foundation pit supporting structure and construction method
The invention relates to a back-anchored rigid foundation pit supporting structure and a construction method. The structure is a near-rigid combined supporting structure jointly formed by back-row anchored piles, front-row supporting piles, rigid connecting walls, pile top longitudinal beams, pile top cross beams and other additional assemblies. According to the supporting type, the available space on the outer side of the outer side line of the underground structure on the inner side of the red line is fully utilized, the space outside the red line is not occupied, anchor rods are not arranged outside the foundation pit, and supports are not arranged in the foundation pit. According to the rear anchor type rigid foundation pit supporting type, firstly, a near-rigid structure is adopted, the overall lateral rigidity is large, deformation displacement is small, secondly, the stability of the supporting structure is greatly improved through the anti-overturning moment provided by the lengthened rear row anchoring piles and the self weight of the structure, stress is clear and definite, construction is easy and convenient, the speed is high, and quality is reliable; the application range of the retaining type supporting structure is expanded, the construction period of foundation pit supporting, earth excavation and an underground structure is greatly shortened, and the construction cost is effectively saved.
本发明涉及一种后锚式刚性基坑支护结构及施工方法，该结构是由后排锚拉桩、前排支撑桩、刚性连接墙、桩顶纵梁、桩顶横梁及其他附加组件共同形成的近刚性组合支护结构。该支护型式充分利用了红线内侧地下结构外边线外侧的可利用空间，是一种可不占用红线外空间、不在基坑外实施锚杆及不在基坑内设置支撑即可形成的基坑支护型式。后锚式刚性基坑支护型式首先是近刚性结构，整体侧向刚度大，变形位移小，其次通过加长的后排锚拉桩及结构自重提供的抗倾覆力矩大幅增加了支护结构的稳定性，受力清晰明确，施工简便、速度快且质量可靠，扩大了支挡式支护结构的应用范围，大幅缩短了基坑支护、土方开挖及地下结构的施工工期并有效节约工程造价。
