地铁车辆段过轨给排水管线的设置

The laying ways of the crossing-rail water supply and drainage pipeline of Subway depot

针对地铁车辆段给排水管线过轨问题,结合工程实例,介绍了过轨给排水管线的常用敷设方式有直接埋地敷设、防护套管敷设、架空敷设、综合管沟敷设,说明了不同敷设方式有其不同的适用范围、敷设要求及优、劣势,必须引起地铁工程设计人员慎重选择。

In view of the crossing-rail problem of water supply and drainage pipelines in subway depot,this paper introduces some common laying ways of crossing-rail water supply and drainage pipelines combine with subway depot projects,which has direct buried laying,protective casing laying,overhead laying,and integrated trench laying.This paper introduces the different applications,laying requirements,advantages and disadvantages of the different methods,which must be carefully selected by subway engineering designers.
