郑西客专桥上CRTSⅡ双块式无砟轨道机械施工技术

The Mechanical Execution Technique of CRTSII Double -block Ballastless Track on the Special Bridge of West Zhengzhou Station

CRTSⅡ双块式无砟轨道是在德国旭普林无砟轨道的基础上，经过改进而中国化的一种轨道类型。其优点是成型后的轨道精度高，轨道几何尺寸能够持久保持，更换受损的无砟轨道更为方便。桥上CRTSⅡ双块式无砟轨道机械施工的重点是混凝土道床板的施工技术。该机械施工方法对测量技术有较高的要求，具有便于操作、速度快、精度高、社会效益明显等优势。

CRTSII ballastless track is a revised Chinese rail type on the basis of German Xupulin ballastless track. Its advantages lie in high trajectory accuracy, long - lasting rail and convenient exchange. The main part of bridge mechanical execution of CRTSII ballastless track is the execution of concrete slab. This kind of execution requires exact measuring technique. It has the advantage of convenient operation, fast speed, high precision and obvious social benefit.
