Large deep foundation pit supporting system and construction method thereof
The invention provides a large deep foundation pit supporting system and a construction method thereof. The large deep foundation pit supporting system comprises supporting piles arranged on the periphery of a foundation pit, waist beam structures are fixed in the height direction of the inner side walls of the supporting piles, anchor cables are connected to the waist beam structures, and the anchor cables are anchored in a peripheral foundation of the foundation pit; a foundation pit bottom sealing layer is fixed to the inner bottom of the foundation pit through anti-floating piles, and a structural foundation layer is arranged on the top of the foundation pit bottom sealing layer. Cap beams are arranged at the tops of the supporting piles, intercepting ditches are arranged on the peripheries of the tops of the cap beams, apron slopes are arranged on the peripheries of the intercepting ditches, and waterproof curtains are arranged on the peripheries of the apron slopes and extend into the foundation on the periphery of the foundation pit. An inter-pile protection plate is arranged between every two adjacent supporting piles and anchored in the peripheral foundation through a reinforcing anchor rod. The supporting system is high in waterproofness and good in stability, can meet the requirement for small deformation of the foundation pit when facing the foundation pit of the strong permeable stratum, and meanwhile can guarantee safe operation in the foundation pit for a long time.
本发明提供了一种大型深基坑支护体系及其施工方法，包括设置在基坑外围的支撑桩，沿着支撑桩内侧壁的高度方向固定有腰梁结构，腰梁结构上联接有锚索，锚索锚固在基坑的外围基础内部；基坑的内底部通过抗浮桩固定有基坑底封闭层，基坑底封闭层的顶部设置有结构基础层；支撑桩的顶部设置有帽梁，帽梁的顶部外围设置有截水沟，截水沟的外围设置有散水坡，散水坡的外围并伸入到基坑外围基础内部设置有止水帷幕；相邻支撑桩之间设置有桩间防护板，桩间防护板通过加强锚杆锚固在外围基础内部。该支护体系防水性强，稳定性好，在面对强透水地层基坑时，该支护体系可以满足基坑变形小的需求，同时能保证长时间基坑内安全作业的问题。
