Combined retaining wall of ultra-deep basement and construction method of combined retaining wall
The invention discloses a combined retaining wall of an ultra-deep basement and a construction method of the combined retaining wall. Comprising a foundation slab and wall steel bars, the inclined supporting steel bars are horizontally arranged along the wall body steel bars, the inclined supporting steel bars are vertically arranged between the wall body steel bars and the foundation bottom plate, and a rubble filling layer is arranged in a triangular closed space formed among the wall body steel bars, the foundation bottom plate and the inclined supporting steel bars. A soil filling layer is arranged above an open space formed among the wall steel bars, the foundation slab and the inclined supporting steel bars, namely the triangular closed space. According to the combined retaining wall, the gravity center of the retaining wall effectively moves backwards to form a slope surface, so that the anti-overturning stability coefficient of the retaining wall is increased, meanwhile, the soil retaining bearing capacity of the rubble gravity type retaining wall can be remarkably improved under the condition of the same section size, and the slippage resistance of the retaining wall is effectively enhanced.
本发明是一种超深地下室的组合式挡土墙及其建造方法；包括基础底板、墙体钢筋；还包括沿墙体钢筋水平布置的斜向支撑钢筋以及沿墙体钢筋、基础底板之间竖向布置的倾斜支撑钢筋，在墙体钢筋、基础底板及倾斜支撑钢筋之间形成的三角形闭合空间中设置毛石填充层，在墙体钢筋、基础底板及倾斜支撑钢筋之间形成的开放空间，即三角形闭合空间的上方设置填土层。本发明所提出的组合式挡土墙，有效将挡土墙的重心后移并形成坡面，从而增大挡土墙的抗倾覆稳定系数，同时相同的截面尺寸情况下也能显著提高毛石重力式挡土墙的挡土承载力，有效加强挡土墙的抵抗滑移能力。
