既有地铁车辆段排水管道穿越既有轨道及道路技术方案比选

Comparison and selection of technical schemes for water supply and drainage pipelines crossing existing tracks and roads in existing metro depot

随着国内地铁车辆段建成数量的增多,对车辆段的改建、扩建工程也随之增多,在车辆段改建、扩建工程中给排水管道穿越既有轨道及道路的工程也随之增多。既有轨道涉及到列车的运营安全,既有道路下方管线复杂,给排水管道穿越既有轨道和道路时,选择合适技术方案至关重要。以沈阳地铁2号线浑南车辆段为例,对3种技术方案进行探讨及比选,以期对既有地铁车辆段给排水管道穿越既有轨道及道路技术方案起到一定的指导作用。

With the increase of built metro depots, the reconstruction and expansion of the depots are increasing, and the cases of the drainage pipelines crossing the existing tracks and roads are also increasing in the reconstruction and expansion of the depots. The existing tracks relate to the salty of train operation, the pipelines below the existing roads are complex, and it is very important to choose the suitable technical scheme when the water supply and sewerage pipelines cross the existing tracks and roads. Taking the Hunnan depot of Shenyang Metro Line 2 as an example, this paper discussed and compared three technical schemes, which is expected to provide guidelines inthe technical scheme selection for water pipelines cross- ing existing railways and roads in existing metro depots.
