Supporting structure of arch-shaped supporting foundation pit and construction method
The supporting structure of the arch-shaped supporting foundation pit comprises a downwards-excavated underground continuous wall body, a concrete straight support, a steel stand column, a stand column pile, an arch-shaped supporting beam and a steel support, one section of the steel stand column is arranged in the stand column pile, and the other end of the steel stand column is connected with the concrete straight support; arch-shaped supporting beams are arranged on the two sides of the steel stand columns, and embedded bolt holes are formed in the arch-shaped supporting beams; a steel support is arranged on the arch back face of the arch-shaped supporting beam, one end of the steel support is connected with the arch-shaped supporting beam, and the other end of the steel support is connected with the underground continuous wall. The segmented arched supporting beam assembly structures are mutually offset, middle horizontal soil pressure is transmitted to the segmented arched supporting beam assembly structures through the steel supports to be mutually offset, upward pulling force received by the arched supporting beams is transmitted to the stand column piles through the steel stand columns to be offset through soil friction force, and stability of the foundation pit is guaranteed; when a foundation pit supporting system is completely formed, most of core soil in the foundation pit is reserved, and deformation of the foundation pit is reduced.
本发明公开了一种拱形支撑基坑的支护结构，包括下挖的地下连续墙体，混凝土直撑，钢立柱，立柱桩，拱型支撑梁和钢支撑，所述钢立柱一段设置在立柱桩内，另一端与混凝土直撑连接；所述钢立柱两侧设有拱型支撑梁，所述拱形支撑梁内部设有预埋螺栓孔；所述拱形支撑梁弓背面设有钢支撑，所述钢支撑一端与拱形支撑梁连接，另一端与地下连续墙体连接。通过多个分段拱形支撑梁拼装结构相互抵消，中部水平土压力通过钢支撑传递至多个分段拱形支撑梁拼装结构相互抵消，拱形支撑梁所收到的上拔力通过钢立柱传递至立柱桩通过土摩擦力抵消，保证了基坑的稳定，在基坑支护体系全部形成的同时，保留了大部分基坑内核心土，减少了基坑的变形。
