Efficient and self-stabilizing foundation pit supporting structure and construction method thereof
The invention discloses an efficient and self-stabilizing foundation pit supporting structure and a construction method thereof.The supporting structure comprises a foundation pit continuous wall and supporting walls, the foundation pit continuous wall is arranged on the periphery of a foundation pit in a surrounding mode, the foundation pit continuous wall is of a polygonal structure according to the shape of the foundation pit, and the supporting walls are arranged on the periphery of the outer side of the polygonal foundation pit continuous wall. A supporting framework in the supporting wall is connected with a reinforcement cage in the foundation pit continuous wall, after concrete is poured into the foundation pit continuous wall, the supporting wall and the foundation pit continuous wall at the position where the supporting wall is located form an integrated structure, and the thickness of the supporting wall is the same as that of the foundation pit continuous wall. The device has the beneficial effects that the counter pressure effect of the dead weight of soil above the inclined supporting wall on the supporting wall surface is utilized, and the effects of limiting the inclined supporting wall from being lifted upwards and limiting the foundation pit continuous wall from deflecting and deforming towards the interior of a foundation pit are achieved, namely, the self-stabilizing effect is achieved. And a conventional in-pit supporting system can be omitted, so that the efficiency of earth excavation in the foundation pit is greatly improved, and the construction period can be remarkably shortened.
本发明公开了一种高效、自稳定基坑支护结构及其施工方法，支护结构包括有基坑连续墙和支撑墙，其中基坑连续墙围设在基坑的周边，基坑连续墙按照基坑的形状设为多边形结构，多边形的基坑连续墙外侧的周圈设置有数道支撑墙。支撑墙内的支撑骨架与基坑连续墙内的钢筋笼相连接，基坑连续墙浇筑混凝土后，支撑墙与所在位置处的基坑连续墙形成为一体结构，支撑墙的厚度与基坑连续墙的厚度相同。有益效果：利用倾斜支撑墙上方土体自重对支撑墙面的反压作用，起到限制倾斜支撑墙上抬和基坑连续墙向基坑内偏转变形的作用，即，自稳定效果。能够取消常规的坑内支撑体系，为此大幅提升基坑内土方开挖的效率并可显著节省施工周期。
