富水地区运营地铁车站渗漏水治理关键技术
|
摘要
城市地下轨道因其准点率高、运载量大、节约地面空间等种种优点成为城市交通的新宠。然而作为地下结构,地铁车站渗漏水的普遍性和反复性给运营造成了种种不便,富水地区水患问题尤为突出~([1])。为减少运营安全风险,建立一套运营期间水患治理的施工理论和关键技术,笔者以天津地铁6号线首开段南翠屏站运营期间渗漏水实际处理情况为研究背景,总结了车站常见的渗漏水状况和运营期间处理渗漏水的思路,针对不同部位和漏水的严重程度提出了有效的治理方法,对于车站渗漏水的治理具有可操作性和指导意义。
Urban underground railway has become a new favorite of municipal construction due to its high on-time rate, large carrying capacity, and saving space on the ground. However, as an underground structure, the universality and repeatability of the leakage of the subway station in the water rich area have caused inconvenience to the operation. In order to reduce the risk of operation safety and establish a set of construction theory and key technology for the management of water in the operation period, the author takes the actual treatment situation of the seepage water leakage during the operation of the Tianjin Metro Line 6 in the first section of the Nancuiping station, summarizes the common seepage water situation in the station and the thought of dealing with the leakage of water during the operation. The effective treatment method is put forward for the location and the severity of the leakage, which is feasible and instructive for the treatment of the station's leakage water.
