【摘要】 目前北京地铁施工采用的常规管井降水,很难疏干弱透水层中的饱和水和含水层界面残留水,使得各施工标段均有带水作业现象,这给快速经济地进行隧道开挖、安全文明施工带来很大隐患,是目前地铁工程施工亟待解决的降水难题。本文介绍了北京地铁十号线劲松站～折返点区间暗挖段真空深井降水施工情况和降水效果,可为类似工程借鉴。更多还原

【Abstract】 Tube well dewatering is always used in Beijing subway construction,but saturation water in weak permeable stratum and residual water in the interface of water bearing layer are difficult to drain,which affects tunnel excavation and safety construction a lot.It has become a critical problem to be settled in subway engineering.Vacuum deep well dewatering in mining tunnel between Jingsong Station and reentry of Beijing Subway Line 10 has been presented in this paper.It can be helpful for other construction.更多还原
