随着我国铁路事业的高速发展,越来越多的客运专线开始开工建设,作为CRTSⅠ型板系统的应用也将越来越广泛。轨道板底座及凸形挡台是CRTSⅠ型板系统的重要结构设施,轨道板底座砼连接着桥面和轨道板有着承上启下的作用,凸形挡台是固定轨道板控制其移动的最重要设施。因此轨道板底座及凸形挡台的质量的好坏直接关系到无砟轨道的整体工程质量,稍有松懈就可能出现重大质量问题。
With the rapid development of the railway industry in our country, more and more Passenger Dedicated Lines are under construction and will be more and more widely used as the CRTS Ⅰ type slab system. The base plate of the track slab and the convex block are the important structural facilities of the CRTS Ⅰ slab system. The slab base of the rail slab is connected with the deck and the track slab. The convex stop is the most important facility for controlling the movement of the slab track plate. Therefore, the quality of the track plate base and convex block is directly related to the overall quality of the ballastless track, a slight slack may occur major quality problems.
