组合支撑体系在深窄基坑支护中的应用OA

As a critical component of construction engineering,deep foundation pit projects are usually located in areas with dense buildings,high groundwater levels,narrow construction sites and complex surrounding environments,resulting in high construction difficulty.This paper adopts a composite support system consisting of"diaphragm wall+anchor cable+steel pipe internal support".Compared with the traditional internal support system,this system significantly improves construction efficiency.Meanwhile,the three dimensional support system composed of vertical diaphragm wall support combined with anchor cables and steel pipe supports can fully utilize the limited construction space,improve space utilization efficiency,and create more favorable conditions for subsequent engineering construction.This method provides a reliable solution for the construction of deep and narrow foundation pits in complex environments,and has certain popularization and application value.
