客运枢纽车站改造施工方案研究

客运枢纽车站改造施工是一个复杂的综合性工程项目,涉及路基、桥涵、轨道、接触网、通信、信号、电力等专业,技术复杂、相互干扰多、安全风险高,且天窗内施工要在有限的时间和空间内按计划完成施工任务,施工方案必须成熟可靠、思虑周全,具有可操作性才能确保行车安全、施工安全、设备安全。本文结合银川站站场改造实践经验,对客运枢纽站场改造的设计方案优化进行研究,从保障运输秩序、降低安全风险、提高营业线及邻近营业线施工工效等方面考虑,为后期类似的站改施工可以安全、高效、有序地进行,并将行车干扰降至最低提供了可借鉴的技术和经验。

Scheme Research on Reconstructing Passenger Terminal Station

The reconstruction of passenger terminal station is a complex and comprehensive project,involving subgrade,bridge and culvert,track,catenary,communication,signal,electric power and other disciplines,with complex technology,multiple mutual interference,high safety risk,etc.In addition,the construction during permitted time should be completed according to the plan in limited time and space,and the construction scheme must be mature,reliable,thoughtful and operable to ensure driving safety,construction safety and equipment safety.With the practical experience of Yinchuan Station reconstruction,this paper studied the optimization of the design scheme for the station reconstruction of the passenger transport hub in consideration of ensuring the transportation order,reducing the safety risk,improving the construction efficiency of the business line and the adjacent business line.The technology and experience could be served as reference for similar station reconstruction in the later period with safety,efficiency and order,minimizing the impact on the traffic interference.
