地铁车站排水系统的深化设计

Detail design of drainage system in metro station

结合近几年的地铁车站给排水设计实例,介绍地铁排水系统设计的要点。分析对比了常规污水池潜污泵提升、密闭式污水提升、真空式污水提升3种不同的污水提升方式,现阶段国内大部分车站倾向于选用密闭式提升装置,半真空式污水提升方式仍处于测试阶段,未大规模使用。最后概括了几种常用的防排水措施,并对今后的设计提出了改进和建议。

Based on the instances of design and construction of metro stations in recent years, this paper introduced the key points of drainage system design of metro station.It analyzed and compared 3different sewage lifting modes,which included conventional sewerage tank submerged sewage pump lifting,sealed sewage pump lifting,and vacuum sewage lifting.Currently,most of the metro stations in China used the sealed sewage pump lifting equipment and half-vacuum sewage lifting mode was still in testing stage and was not used widely.Finally,this paper summarized some normal water proofing and drainage measures and brought forward some suggestions for the design modification in the future.
