摘　　要：既有线改造施工通常面临线路运输繁忙、牵引供电复杂、接触网改造施工难度大、技术要求高的问题。在既有线改造过程中,接触网是整体性、针对性较强的专业,为不影响线路拨接,将既有接触网支柱改移或过渡是必要的,且应在线路拨接插入前进行拆除,在施工中采用正确的施工方案是取得良好工程质量效果的重中之重。针对接触网改造施工中天窗时间短、改造施工复杂、专业接口多等特点,对接触网改造施工技术方案及基本施工方法进行研究和总结,确保铁路运输的效率和工程建设有序进行,为既有线接触网改造施工提供借鉴。The reconstruction of existing lines usually faces the problems of busy line transportation,complicated traction power supply,great difficulty in OCL reconstruction and high technical requirements.During the reconstruction of the existing line,the OCL is a discipline with strong integrity and pertinence.In order not to affect the line connection,changing or transition the existing OCL masts is necessary,and they should be removed before the line connection and insertion.The correct construction scheme is the top priority to achieve good project quality.In view of the characteristics of short time of skylight,complicated reconstruction construction and interfaces among the multiple disciplines in the reconstruction of the OCL,the technical scheme and basic construction methods for the reconstruction of the OCL are studied and summarized to ensure the efficiency of railway transportation and orderly construction of the project,and it is able to provide reference for the reconstruction of the existing OCL.
