城市轨道交通车辆基地室外综合管沟的应用研究

室外管线综合设计是城市轨道交通车辆基地设计的重点和难点,通常室外管线多以直埋的方式敷设于地下,但这种方式在设计、施工、运营维护阶段均存在着一些问题,因此提出了在室外设置综合管沟的方式,尽可能解决目前出现的问题.针对相关问题,提出了设置室外综合管沟的必要性和意义,从入沟管线种类分析、综合管沟管线布置原则、断面设计、特殊节...

Theoretical Study about Utility Tunnels in Base for the Vehicle of Urban Rail Transit

The layout design of outdoor pipelines is a key and difficult task for the construction of the base for the vehicle of urban rail transit. Outdoor pipelines are always buried directly underground. However, there are some problems with this approach in the stages of design, construction, operation, and maintenance. Therefore, the installation of the utility tunnel provides an idea for solving existing problems. Aiming at these related problems, the necessity and significance of setting up outdoor utility tunnels are described. This paper introduces a theoretical study on utility tunnels from many aspects, including the analysis of the type of pipelines, the layout principle of the utility tunnel, the design of the section, the design of special nodes, and the auxiliary engineering of utility tunnels.
