Underground garage foundation pit supporting structure and construction method
The invention discloses an underground garage foundation pit supporting structure and a construction method, and relates to the technical field of foundation pit supporting. In order to solve the problem that the supporting safety close to a supporting pile is not high, the supporting structure comprises a side supporting assembly arranged on the inner wall of the periphery of a foundation pit formed in the top face of a soil layer, the side supporting assembly is composed of a foundation supporting part and a reinforcing supporting part, and an inclined slope is excavated on the top face of the soil layer around the edge of the top of the periphery of the foundation pit. The construction method of the supporting structure comprises the steps of leveling a site; constructing the supporting piles; earth is excavated, the slope surface of the foundation pit is leveled, and a concrete protection surface is sprayed to construct a protection slope and a top beam. According to the method, the situation that the foundation pit is unstable and collapsed due to large deformation caused by single use of the foundation supporting part for maintenance is avoided, the safety and stability of foundation pit supporting can be ensured, the safety of foundation pit earth excavation and surrounding buildings (structures) and the like is ensured, the reinforcing supporting part can be used repeatedly, the disassembly and assembly speed is high, and then the overall construction efficiency of the foundation pit can be improved.
本发明公开了一种地下车库基坑支护结构及施工方法，涉及基坑支护技术领域。为了解决紧靠支护桩支护安全性不高的问题，该支护结构，包括设置于开设于土层顶部面的基坑四周内壁的侧面支护组件，所述侧面支护组件由基础支护部和加固支护部组成，围绕基坑四周顶部边沿的所述土层顶部面开挖有倾斜坡面。该支护结构施工方法，包括平整场地：支护桩施工；土方开挖并整平基坑坡面，喷砼护面施工护坡和冠梁。本发明避免单使用基础支护部维护而导致其变形量较大，造成基坑失稳坍塌，能够确保基坑支护的安全稳定，确保基坑土方开挖及周围建(构)筑物等的安全性，并且加固支护部可多次周转使用，拆装速度快，进而能够提高基坑整体施工效率。
