Research conclusions:(1)In the construction of rail transit, in order to intensive use of land，projects for depot with cover are increasing. Meanwhile，depot layout design is conditioned by it.(2)Design of outdoor comprehensive pipeline for depot needs to give full consideration to the effect of cover, and comprehensive pipeline of outdoor channel is planned in advance. At the moment of the preliminary design for cover, the interface of outdoor pipeline design must be clear， and the height and size for the key nodes of foundation beam for cover are controlled.(3)Numbers of outdoor pipeline for depot with cover are related with forms of development planning，Which mainly contain the domestic sewage pipe，rain pipe，power cable，etc.(4)The outdoor pipeline layout for cover depot is different from regular depot，such as the station drainage，road slope settings，line numbers，and so on .The design of outdoor pipeline layout for a cover depot should give full consideration to foundation beam of pipe laying，to consider the reserved of tower crane foundation，and the pipeline installation space for general layout，etc.(5)The research results can provide a reference for similar project of depot comprehensive outdoor pipeline design with cover.
