Deep foundation pit supporting system and construction method thereof
The invention belongs to the technical field of foundation pit engineering, particularly relates to a deep foundation pit supporting system and a construction method thereof, and provides the following scheme to solve the problems proposed in the background technology: the deep foundation pit supporting system comprises a supporting seat, a connecting seat and an anti-settling seat which are distributed from bottom to top; a supporting mechanism and a lifting mechanism are arranged between the supporting seat and the connecting seat; the construction method of the deep foundation pit supporting system comprises the following steps that the supporting seat is placed in a deep foundation pit, and then all butterfly-shaped screws are rotated in sequence, so that all soil drilling rods are drilled into soil of the deep foundation pit to be locked and fixed. The protection height of the anti-settling seat can be adjusted according to the depth of the deep foundation pit through a lifting assembly; by means of a stand column assembly, the probability of uneven settlement is reduced; and through a backfilling assembly, soil in the soil containing barrel can be discharged to the outside for soil filling operation, so that the problem that the deep foundation pit severely sinks due to long-time soil loss is solved.
本发明属于基坑工程技术领域，尤其是一种深基坑支护体系及其施工方法，针对背景技术提出的问题，现提出以下方案，所述深基坑支护体系，包括自下而上分布的支撑座、连接座和防沉降座，所述支撑座和连接座之间设有支护机构和升降机构；所述深基坑支护体系的施工方法，包括以下步骤：S1：将支撑座放置在深基坑内，然后依次转动各个蝶形螺杆使得所有的钻土杆钻进深基坑泥土内进行锁死固定。本发明通过升降组件能够根据该深基坑的深度来调整防沉降座的防护高度；通过立柱组件，降低了不均匀沉降情况发生的概率；通过回填组件能够对装土筒内的土壤排至外界进行填土操作，以克服长时间的土壤流失会造成深基坑的严重下陷问题。
