Soft soil deep foundation pit combined supporting structure and construction method
The invention relates to a soft soil deep foundation pit combined supporting structure and a construction method thereof, which are applied to the field of foundation pit supporting technology. The soft soil deep foundation pit combined supporting structure comprises a double-row pile body, the double-row pile body comprises front-row piles and rear-row piles which are arranged in parallel, the front-row piles are arranged along the periphery of a foundation pit, the rear-row piles are located on the sides, back on to the foundation pit, of the front-row piles, pile top connecting beams are connected between the pile tops of the front-row piles and the pile tops of the rear-row piles, soft soil is filled between the front-row piles and the rear-row piles, mutually-meshed waterproof curtain piles are arranged between pile bodies of the adjacent front-row piles, a plurality of supporting boxes are arranged in the foundation pit and fixed in the soft soil at the bottom of the foundation pit, inclined supporting columns are arranged between the supporting boxes and the front-row piles, and the supporting boxes and the inclined supporting columns are arranged in a one-to-one correspondence mode. One ends of the inclined supporting columns are hinged to the front-row piles, the other ends of the inclined supporting columns are located in the supporting boxes, an abutting mechanism used for pushing the inclined supporting columns to abut against the front-row piles is arranged in the foundation pit, and the abutting mechanism is fixed to the supporting boxes. The effect of improving the stability of the foundation pit supporting structure is achieved.
本申请涉及一种软土深基坑组合支护结构及施工方法，应用在基坑支护技术的领域，其包括双排桩本体，双排桩本体包括相互平行排列的前排桩和后排桩，前排桩沿基坑周缘设置，后排桩位于前排桩背向基坑的一侧，前排桩和后排桩的桩顶间连接有桩顶连梁，软土填充在前排桩与后排桩之间，相邻前排桩的桩体之间设有相互咬合的止水帷幕桩，基坑内设有若干抵撑箱，抵撑箱固定在基坑底部的软土内，抵撑箱与前排桩之间设有斜撑柱，抵撑箱和斜撑柱一一对应设置；斜撑柱的一端铰接在前排桩上，斜撑柱的另一端位于抵撑箱内，基坑内设有用于推动斜撑柱抵紧前排桩的抵紧机构，抵紧机构固定在抵撑箱上。本申请具有提高基坑支护结构的稳定性的效果。
