1 CRTSⅡ型板式无砟轨道系统简介CRTSⅡ型板式无砟轨道系统主要由两布一膜滑动层、混凝土底座板、砂浆垫层、轨道板、扣件、钢轨组成,侧向挡块限制其横向位移,如图1所示。箱梁和底座板之间的滑动层由两层无纺布中间加一层聚乙烯薄膜组成,下层土工布采用合适的胶合剂将其粘贴在喷涂防水层上;底座板为连续通长结构,连续跨
1 Introduction of CRTS Ⅱ slabless track system The CRTS Ⅱ slabless ballastless track system mainly consists of two layers of cloth sliding layer, concrete base plate, mortar cushion, track plate, fastener and rail, and lateral stop to limit its lateral displacement ,As shown in Figure 1. The sliding layer between the box girder and the base plate is made of two layers of non-woven fabric with a polyethylene film in the middle. The lower geotextile is glued to the waterproof layer by a suitable glue. The base plate is a continuous long- Continuous cross
