烟台市110k V龙梁线电缆隧道条形基坑支护工程,基坑周边环境条件复杂,对基坑稳定性要求控制严格,作业面狭小,施工难度大。通过分析其工程地质条件和水文地质条件,综合经济、技术比较,最终确定该基坑工程采用钢管桩+内支撑+水泥土搅拌桩支护形式,并对内支撑设计做了创新,根据基坑监测及完工后效果,能够保障基坑的稳定。
Yantai 110k V Long beam cable tunnel tunnel excavation supporting project, surrounding the foundation pit surrounding the complex conditions of the stability of the control of the pit rigorous rigorous control, small operating surface, construction is difficult. Through the analysis of its engineering geological conditions and hydrogeological conditions, and comprehensive economic and technical comparison, it is finally determined that the steel pipe pile + internal support + cement-soil mixing pile supporting form is adopted for this foundation pit project and the internal support design is innovated. Based on the foundation Pit monitoring and post-completion results, to protect the stability of the pit.
