邻近既有公路深基坑钢板桩围护结构施工工艺

Construction Technology of Steel Sheet Pile Enclosure Structure for Deep Foundation Pits Adjacent to Existing Highways

深基坑钢板桩施工过程中,常常会选择使用拉森钢板桩围护,这种形式的围护施工便捷,施工时间短,钢板桩可以租赁,支撑结构具备良好的安全性与稳定性,施工成本较低,比较合适应用在基坑开挖深度不超过10 m的项目中。文章结合具体工程案例,深入分析了邻近既有公路深基坑钢板桩围护结构施工方案及具体施工方法,以期通过应用合理的施工方法,提高深基坑钢板桩围护结构施工效率。

In the process of steel sheet pile construction in deep foundation pit,Larsen steel sheet pile enclosure is often used.This form of enclosure construction is convenient,the construction time is short,the steel sheet pile can be leased,the support structure has good safety and stability,and the construction cost is low.It is more suitable for application in projects with excavation depth of foundation pits less than 10 m.Combined with specific engineering cases,this paper deeply analyzes the construction scheme and specific construction methods of steel sheet pile enclosure structure for deep foundation pit adjacent to existing highways,in order to improve the construction efficiency of steel sheet pile enclosure structure for deep foundation pits by applying reasonable construction methods.
