摘要
为减少地下障碍物清障过程中土体扰动对地铁设施和周边环境的影响,结合上海某项目实际清障施工案例,对紧邻地铁运营区间隧道的深埋式原水管清障方案进行探讨。从地铁周边施工的微扰动控制、临时支护止水方案、开挖风险管理等方面入手,详细总结了深埋地下管线清障的施工方法,以期为类似项目提供借鉴。
To reduce the impact of soil disturbance on subway facilities and surrounding environment in the process of removing underground obstacles,combined with the actual construction case of a project in Shanghai,the scheme of removing deep buried existing water pipe in the tunnel adjacent to the subway operation section is discussed.From the micro-disturbance control,temporary support water stop scheme,excavation risk management and other aspects of surrounding subway construction,the construction methods of deep buried underground pipeline obstacle removal are summarized in detail so as to provide reference for similar projects.
