摘要
以濒临国道穿越电缆逆作法车站为例,总结了濒临敏感环境受电缆影响围护结构无法闭合情况下的围护结构闭合处理技术。为解决围护结构无法闭合导致围护结构外侧水土沿未闭合围护结构处向基坑内渗漏、对车站周边敏感环境造成危害,从开挖流程、注浆工艺和逆作墙体的分段施工方面介绍了该工况下围护结构闭合处理措施。从后期土方开挖和主体结构施工来看,基坑开挖未出现渗漏,结构施工过程安全顺利,基坑北侧国道通车安全。
Based on the reverse construction station with crossing cable,the closure treatment technologies of the unenclosed enclosure structure are summarized for excavation process,grouting and sectional construction of reverse wall.From later soil excavation and main structure construction,there is no leakage of the foundation pit,the construction process of the structure is safe and smooth,and the national road is opened to traffic safely.
