铁路客运专线站前施工单位为站后"四电"施工单位提供预留接口的时间与质量,直接影响站后"四电"施工单位的施工工期与质量。结合杭甬铁路客运专线"四电"专业的施工,对施工过程中站前施工单位为站后"四电"施工单位提供预留接口时间、质量提出建议,按接触网基础、供电线上网预留孔、路基过轨管预留、接地端子几方面,分别对隧道、桥梁、路基、无砟轨道等4个方面分析接口中常见质量问题,提出针对性防治方法。
The time and quality of the reserved interface of passenger dedicated railway station by construction contractor decides the construction periods and quality of the ＂four electric＂ contractor.Combined with the Hangzhou-Ningbo Railway Passenger Dedicated Line ＂four electric＂ construction,suggestions are proposed for the post construction ＂four electric＂ reserve in interface reserved time,quality.Based on the contact net foundation,power supply line preformed hole,roadbed track tube reservation,grounding terminal,problems in four aspects of tunnel,bridge,ballastless track subgrade are analyzed and prevention methods are put forward.
