悬挂式单轨交通车辆基地站场设计关键技术研究

Key Technologies of Vehicle Base Station Design for Suspended Monorail Transit

[目的]悬挂式单轨交通车辆基地的总平面布局形式直接影响列车作业及工程造价。道岔选型对车辆基地站场总平面布局影响较大,运用库单线列位数的选择也将直接影响道岔数量及段场规模,因此需对悬挂式单轨交通车辆基地站场设计的关键技术进行深入研究。[方法]依托武汉光谷生态大走廊悬挂式单轨交通工程的龙泉山车辆段,阐述了该车辆段的总平面布局形式及创新点,分析了该车辆段道岔选型及场坪标高的制定方法,建立了理想条件下车辆段运用库单线列位数模型。[结果及结论]悬挂式单轨交通车辆基地总平面布置宜采用贯通式洗车方案,将洗车库放在出入线上;咽喉设计时,需同时考虑桥墩布置的美观性;需联合道岔厂家加快对三开道岔及五开道岔的研发,并合理选用不同道岔组合以更进一步节省投资;在不考虑其他作业干扰的理想条件下,悬挂式单轨交通车辆基地运用库最多可采用1线5列位,实际设计过程中需结合车辆基地条件、综合考虑列车出库的便捷性、扣除其他作业干扰等因素选择合适的运用库单线列位数。

[Objective]The overall plane layout of the suspended monorail transit vehicle base directly affects train′s operation and engineering cost.The turnout type selection has a great influence on the overall layout of the depot,and the selection of single line train position number in the depot also directly affects the number of turnouts and the scale of the depot.Therefore,it is necessary to make in-depth research on the key technologies for the depot layout design.[Method]Based on the Longquanshan Vehicle Base of suspended monorail transit project in Wuhan Optics Valley Ecological Corridor,its overall plane layout and innovation points are introduced.The turnout type selection and the formulation of the field elevation in the depot are analyzed,and a model of single line train position number under ideal condition is established.[Result&Conclusion]The overall plane layout of the suspended monorail vehicle base should adopt the through type train washing scheme,and the access line is suitable for the train washing location.The aesthetics of bridge pier layout should be considered in the throat design.It is necessary to cooperate with turnout manufacturers to speed up the research and development of three-way turnout and five-way turnout,and rationally select different turnout groups to further save the investment;under ideal conditions without considering other operation interference,up to 5 train positions on a single line can be adopted in the suspension monorail depot.In the actual design process,the proper single line train position number is selected considering the factors such as the vehicle base condition,the train exit convenience and other operation interference.
