中新网贵阳11月11日电 (记者 瞿宏伦)记者11日从中国铁路成都局集团有限公司(以下简称:国铁成都局)获悉,11月10日,随着川黔铁路七龙星至民福寺区间线路大机捣固施工作业完毕,标志着为期33天的川黔、渝怀铁路2026年集中修圆满收官。

川黔铁路于1965年开通运营,北起重庆,南至贵州,是中国西南地区路网骨架的重要组成部分,也是西部陆海新通道铁海联运的重要干线之一。渝怀铁路作为连接重庆市与湖南省怀化市的国铁Ⅰ级双线电气化铁路,是西南地区衔接长江经济带与西部陆海新通道的关键交通要道,承担着保障区域客货运输高效运转的重要任务。自10月9日起,国铁成都局同步启动两条线路的设备集中整治施工。

为确保此次集中修安全稳定、有序推进,国铁成都局在重庆、遵义设立现场指挥部,统筹重庆工务段、贵阳工务段、涪陵工务段、成都工务大机段、成都工务大修段、重庆电务段、贵阳电务段、重庆供电段等10余家单位、超5000余名作业人员协同作战,有序开展换轨、清筛、捣固、打磨等养护维修作业。

期间,各单位积极创新工艺工法,不断提升作业质效。重庆工务段针对线路弯道多、半径小的实际,首次在同一个天窗时段内,采用高难度闪光焊接工艺,分别处理线路的“起始接头”和“中间合龙点”两处焊接点;贵阳工务段创新推行“当日切筛卸捣”一体化作业新模式,并采用“闪光焊+气焊”同步焊接工艺,让道床清筛、换轨施工质效大幅提升;成都工务大机段对既有设备进行改造,首次采用“彻底大扫除”的方式,利用大型机械对铁路轨道两侧的道床石砟进行深度清洁和维护。

此次集中修圆满完成川黔铁路大修换轨75公里、大机贯通清筛35公里、道岔清筛23组、线路大机捣固207公里、道岔大机捣固187组;渝怀铁路大机捣固217公里、线路大机打磨323公里、大修换枕23550根等重点任务,有效消除了各类设备隐患,进一步提升了线路设备质量,为冬季客货运输及后续春运安全畅通提供坚实保障。
