摘要
根据武汉市轨道交通2号线采用的B1型车三轨下部受电的特点,提出在土建设计时,不管转辙机安装在道岔内侧还是外侧,只需根据信号专业的要求,考虑转辙机安装空间的预留、限界专业的要求以及道岔内外侧的加宽量。对曲线进站、设有停车线及人防隔断门等的车站限界要点进行分析,在确保行车安全的前提下节省土建投资。
Considering the features of type B1 vehicles adopted on Wuhan rail transit line 2 with third rail traction, the paper deems that during civil engineering design of the station the switch machine can be installed either on the inside or on the outside of turnout, only accounting for the requirements of signals, the space for the instalhtion of switch machine, requirements of clearance, line widening inside and outside of the turnout. The key requirements of structure clearance for the metro stations with curve approach line, stabling line, civil air defence door and so on are also analyzed in order to save the cost of civil engineering accounting for operation safety.
