The jointless track on bridge is different from the jointless track laying on the traditional subgrade.

桥上无缝线路不同于一般铺设在路基上的无缝线路,本文分析了桥上无缝线路的特点.

Ballast cleaning machine is an essential maintenance machinery of modern railway which performs track-laying, maintenance and the repair of the railway. Its working quality directly affects the quality of the railway and the safety of train travel.

道碴清筛机是现代铁路线路铺设、养护及检修必不可少的铁路养护机械，其工作质量的好坏直接对铁路线路的质量及车辆的运行安全产生影响。

Therefore, rigid jointless track laying must be carried out under specific thermal conditions to avoid dangerous tensile and compressive stress in the rails during extreme weather.

因此在铺设无缝线路时，钢轨温度需要保持在一定的范围内，以避免恶劣气候条件下钢轨内部产生的拉伸应力对其产生的损害。

During the laying works of the railway track, there are higher demands on the building of railway bridge and the work is more difficult than other works.

在铁轨铺设工程当中，对铁路桥梁的架设要求较高，施工的难度也相对较大，这就势必推动相关技术的发展。
