随着既有线的几次提速,普通无缝线路已大规模投入使用,促进了百米长轨的生产与新旧轨更的换作业模式的出现,鉴于我国铁路大型养路机械在换轨施工作业尤其是旧钢轨换轨大修作业中还处于不够成熟的阶段,所以现场换轨还是人工作业模式为主。因此在施工中需要通过各部门的全力配合,充分调查准备和核算分析,按照严格的换轨施工要求去进行线路换铺。
With the speed-up of the existing lines, ordinary seamless lines have been put into large-scale operation, which has promoted the emergence of the production mode of 100-meter long tracks and the replacement of old and new tracks. In view of the large-scale construction of track maintenance machinery In particular, the old rail track overhaul operation is still not mature stage, so the scene or manual mode of change-based. Therefore, in the construction needs through the full cooperation of all departments, and fully investigate the preparation and accounting analysis, in accordance with the strict requirements of track change to carry out the line shop.
