1生产实践背景2000年上海铁路局在沪宁繁忙干线上创造的线路大修综合施工方法打破了无缝线路大修道床破底清筛后应通过列车运行获取道床稳定,即道床清筛作业来和长轨条铺设需分期(年度)实施的施工技术观念,实现了道床清筛、铺排换枕和铺设无缝线路长轨条施工的三同步。这一新的施工技术大大减少了线路大修所占用的线路封锁总时分,提高了
1 Production Background In 2000, the Shanghai Railway Bureau created a line overhaul on the Shanghai-Nanjing trunk line comprehensive construction method to break the seamless line overhaul bed broken bottom cleaning should be obtained through train operation ballast bed stability, that is, And the construction of long-rail laying need to be phased (annual) implementation of the concept of technology to achieve the track bed cleaning, laying and replacement of the pillow and the laying of seamless track long track construction of the three synchronized. This new construction technology greatly reduces the total time required for line blockage in line overhaul and improves
