城市轨道交通中小半径曲线轨道磨耗的主要原因是轨底坡设置不正确或不合理,从城市轨道交通整体道床轨道施工方面入手,详细介绍整体道床轨道施工工序,重点阐述施工中轨底坡的控制并分析造成轨底坡不足的原因;针对施工中轨底坡不足的原因提出了改进意见,以达到延长轨道使用寿命的目的。
The main reason of the track abrasion of the small and medium radius curve in urban rail transit is that the rail slope is not set correctly or unreasonably. Starting from the overall construction of the track bed for the urban rail transit, the whole construction process of the track bed is introduced in detail. The control of the rail slope And analyzes the reasons that cause the shortage of rail bottom slope. In view of the reasons for the shortage of rail bottom slope in construction, suggestions are put forward to prolong the service life of the track.
