浅谈地铁盾构隧道内整体道床下渗漏水整治

Discussion on the Treatment of Water Leakage Under Monolithic Track Bed in Metro Shield Tunnel

随着城市轨道交通运营里程的不断递增,城市地下工程结构渗漏水问题越来越多,渗漏水不仅影响结构耐久性,而且会造成隧道内设备受损,危及行车安全。当前针对车站主体结构、明挖、暗挖及盾构区间整体道床上部的堵漏技术比较成熟,但是针对明挖、暗挖及盾构区间内整体道床下部堵漏,由于涉及整体道床轨道行车安全,不能采用普通方式轻易开展堵漏。

With the increasing operation mileage of urban rail transit,there are more and more leakage problems in urban underground engineering structure.The leakage water not only affects the durability of structure,but also causes damage to equipment in tunnel and endangers traffic safety.At present,the leakage control technology for the main structure of the station,open cut,subsurface excavation and the upper part of the monolithic track bed in the shield interval is relatively mature,but for the open cut,subsurface excavation and the lower part of the monolithic track bed in the shield interval,due to the safety of the monolithic track bed,the leakage control can not be carried out easily in the ordinary way.
