利用再用轨焊接成长轨的旧轨无缝线路已在汉(汉西)丹(丹江)线铺设,该线在1980年铺设12.9公里,1981年铺设9.6公里,累计已铺设22.5公里。一年多运营表明,旧轨无缝线路与原有普通线路相比较,其优越性与新轨无缝线路相似。铺设地段原有接头的喷碴、翻浆、混凝土轨枕断裂等线路病害得以有效的控制和改善,线路养护工作量大大减少。 汉丹线旧轨无缝线路的再用轨一部分采用 The old rail seamless track, which welded the long rail with reusable rails, has been laid on the Han (Hanxi) Dan (Danjiang) Line, which was laid 12.9 kilometers in 1980 and 9.6 kilometers in 1981 and has been laid 22.5 kilometers in total. More than one year of operation shows that the advantages of the old track seamless track are similar to the new track seamless track, compared with the original common track. Laying the original joints piers ballast, dumping, concrete sleeper rupture and other line diseases can be effectively controlled and improved, the line maintenance workload greatly reduced.
