Foundation pit slope supporting and reinforcing system and construction method thereof
The invention belongs to the technical field of foundation pit reinforcement, and particularly relates to a foundation pit slope supporting and reinforcing system and a construction method thereof.The foundation pit slope supporting and reinforcing system comprises an original building foundation, and the original building foundation comprises a pile top bearing platform, an independent foundation located in the pile top bearing platform and a building column supported by the independent foundation; a jet grouting pile is arranged on the independent foundation, and a miniature steel pipe pile is arranged on a concentric shaft of the jet grouting pile. Compared with the prior art, according to the foundation pit slope supporting and reinforcing system and the construction method thereof, the high-pressure jet grouting piles and the micro piles are combined together to form a concentric combined structure, the comprehensive problems of foundation reinforcement, underpinning, foundation pit supporting, waterproof curtains and the like can be solved at the same time, vertical excavation of a slope can be achieved, the earthwork excavation amount is reduced, and the construction efficiency is improved. Complex engineering conditions such as narrow sites are met, the construction period can be shortened, the construction efficiency can be improved, the cost can be controlled, the construction quality can be improved, and the universal application and popularization value is achieved for similar engineering.
本发明属于基坑加固技术领域，具体涉及一种基坑边坡支护加固系统及其施工方法,包括原有建筑物基础，所述原有建筑物基础包括桩顶承台、位于桩顶承台内的独立基础以及由独立基础支撑的建筑物柱体；所述独立基础上设置有旋喷桩，在所述旋喷桩同心轴上设置有微型钢管桩。与现有技术相比较，本发明提出的一种基坑边坡支护加固系统及其施工方法，将高压旋喷桩与微型桩结合在一起，形成同心的组合结构，可以同时解决基础加固、托换、基坑支护、止水帷幕等综合问题，能够实现边坡直立开挖，减少土方开挖量，满足场地狭小等工程复杂条件，不仅可以缩短施工周期、提高施工效率，还可以控制成本和提高施工质量，对于类似工程具有普遍的推广应用价值。
