Combined portal type foundation pit supporting system and construction method thereof
The invention provides a combined portal type foundation pit supporting system and a construction method thereof, and relates to the technical field of deep foundation pit engineering. The combined door frame type foundation pit supporting system comprises a door frame type supporting structure, longitudinal connecting beams, grouting steel pipes, anchor rods and a sprayed concrete surface layer. The combined door frame type supporting system is clear in structure stress system, high in rigidity, high in stability, high in deformation resistance and very beneficial to stratum and environment deformation control; supporting utilizes the self-stabilization capacity of the rock stratum, the construction number of drilled piles in the rock stratum is reduced, and the construction difficulty is reduced; supporting a shallow soil layer by using a groutable steel pipe, and meanwhile, grouting from the earth surface as required to fill a karst cave to eliminate the influence of the karst cave on a foundation pit and a permanent building; and the construction steps are clear, the site requirement is low, the construction technology is simple, the construction speed is high, economical efficiency is high, and remarkable social and economic benefits are achieved.
本发明提供一种组合门架式基坑支护体系及其施工方法，涉及深基坑工程技术领域。该组合门架式基坑支护体系，包括门架式支护结构、纵向连接梁、可注浆钢管、锚杆和喷射混凝土面层。该组合门架式支护体系结构受力体系明确、刚度大、稳定性强、抵抗变形能力强，对控制地层及环境变形非常有利；支护利用岩层自稳能力，减少岩层中钻孔桩的施工数量，减小施工难度；利用可注浆钢管支护浅部土层，同时从地表按需进行注浆进行溶洞填充，消除溶洞对基坑和永久建筑物的影响；施工步骤明确、对场地要求低、施工工艺简单、施工速度快，经济性高、具有显著的社会经济效益。
