邻近地铁大尺寸电力管沟原位保护技术研究

Research on In-Situ Protection Technology of Large-Scale Power Pipe Duct Adjacent to Subway

结合某地铁和商业连接通道工程实例,对我国软土地区邻近地铁基坑建设过程中大尺寸电力管沟原位保护技术进行研究。实践证明,该方案技术上可行,效果良好,能有效缩减工期并降低管线迁改费用,可以为今后同类工程提供参考。

Combined with an example of a subway and commercial connecting passage project,the in-situ protection technology of large-scale power pipe duct in the construction process of foundation pit adjacent to subways in soft soil areas in China is studied.Practice has proven that the scheme is technically feasible and effective,can effectively shorten the construction period and reduce the cost of pipeline relocation,and can provide reference for similar projects in the future.
