带上盖开发地铁车辆段室外综合管线设计研究

Design and Research of Outdoor Integrated Pipelines for Metro Depot with the Upper Cover Development

研究目的:根据"资源节约型、环境友好型"两型社会建设要求,带上盖开发地铁车辆段逐渐增多,而车辆段室外综合管线布置直接制约总图布置。通过本研究,拟找到制约室外综合管线布置因素及解决方法。研究结论:(1)在轨道交通建设中,为了集约用地,利用车辆段进行上盖开发项目日趋增多,而带上盖开发车辆段总图布置受其制约;(2)车辆段室外综合管线设计需充分考虑上盖开发的影响,并提前对室外综合管线通道进行规划,在上盖开发开展初步设计时,就必须明确上盖开发与车辆段室外管线设计接口,并对关键节点的开发立柱承台和基础梁等标高及尺寸进行控制;(3)带上盖开发车辆段需增加的室外管线,与其开发的形态有关,一般主要为生活污水管、雨水管、电力电缆等;(4)车辆段上盖开发后,其室外管线布置较常规车辆段,在站场排水沟、道路坡度设置、室外管线数量等方面均有不同,室外综合管线设计时,需充分考虑立柱承台和基础梁对管道敷设的影响,需考虑上盖开发塔吊基础的预留以及总图布置时需留出相应的管线敷设空间等;(5)本研究成果可供类似带上盖开发车辆段室外综合管线工程设计参考。

Research purposes： According to the two type society construction requirements of resource saving and environment friendly, the construction is increasing for metro depots with the upper cover development, however, the layout of outdoor pipelines directly restricts the general layout for depot. Through this research, the factors hindering outdoor pipelines layout and solutions are found. 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.
