在隧道內修建整体道床較木枕碎石道床具有很多优点:行車平稳;坚固耐久;整体性好,綫路維修量小;养护方便;減少了繁重的体力劳动;减少鋼軌爬行,道床整洁;对鋪設无縫綫路更为有利。經过两年多的运营实践,根据××鉄道条件取消了防爬器,鋼軌未見爬行。××鉄道一期工程,除道岔部分外,全部采用了鋼筋混凝土子制短軌枕式整体道床。經两年多的运营实践,除扣件定期涂油外,其他維修工作量很小,軌距、水平未显出变化,行車平稳,很受运营单位欢迎。道岔木枕碎石道床却不同,道岔軌距、水平均不易保持,隧道內綫路的維修工作量都集中在道岔部分,与
The construction of integral track bed in the tunnel is more stable than that of the sleeper bed. The road bed has a lot of advantages: stable running, strong and durable, good overall quality, small line maintenance, convenient maintenance, less heavy manual labor, less rail creeping and tidy track bed, Seams more favorable line. After more than two years of operational practice, according to × × 鉄 Road conditions to cancel the anti-climbing device, no crawling rail. × × 鉄 Road, a project, in addition to the switch part, all with a short-sleeper reinforced concrete sub-sleeper-type bed. After more than two years of operational practice, except for the regular oiling of fasteners, the other maintenance workload is very small, the track gauge and level have not shown any changes, and the traffic has been steady and is very popular with operating units. Turnout wooden pillow pillow bed is different, turnout gauge, the level is not easy to maintain the tunnel line maintenance workload are concentrated in the turnout part, and
