Construction method of foundation pit supporting structure without inner support
The invention discloses a foundation pit supporting structure without an inner support. The foundation pit supporting structure comprises a breast board of an arc-shaped structure. The combining piece is inserted into a pushing rod arranged in the center of the arc top of the inner side of the soil retaining plate, and first connecting rods hinged to the two sides of the soil retaining plate are hinged to the two sides of the soil retaining plate correspondingly; the combining piece converts radial movement of the abutting push rod into traction limiting force of the first connecting rod on the two sides of the soil retaining plate. According to the foundation pit supporting structure without the inner support, the foundation pit wall is supported through mutual cooperation of the arranged soil retaining plates, the first connecting rods and the connectors, compared with the prior art, the fabricated soil retaining structure is convenient to disassemble and maintain, meanwhile, the construction efficiency is improved, mutual restriction can be formed when large soil pressure is borne, and the construction efficiency is improved. And meanwhile, the situation that the foundation pit displaces and deforms, and consequently follow-up construction is affected is effectively prevented.
本发明公开了一种无内支撑的基坑支护结构，包括：弧形结构的挡土板；结合件，其插接于挡土板内侧弧顶中心处设置的抵推杆上，且两侧铰接的第一连接杆分别与挡土板两侧铰接；结合件将对抵推杆的径向移动转化为第一连接杆对挡土板两侧的牵拉限位力。该发明提供的无内支撑的基坑支护结构，通过设置的挡土板、第一连杆和结合件相互配合对基坑壁进行支撑，与现有技术相比，通过装配式挡土结构，方便拆卸维护的同时提高施工效率，并在受到较大土压时，能够形成相互制约，有效防止挡土板发生变形，同时，有效防止基坑发生位移变形影响后续施工。
