CRTSII型双块式无砟轨道施工技术与病害处治技术探讨

The CRTS II Type Double Block Type Ballastless Track Construction and Disease Treatment Technology

在郑西客运专线CRTSII型双块式无砟轨道施工中,采用了德国技术旭普林机械施工和人工轨排施工方法。针对两种施工方法的施工工艺、关键技术及后期运营效果进行了技术性总结,并针对施工过程和后期运营存在的常见病害提出处治措施。

In the construction of the double block CRTSII type ballastless track of Zhengzhou- Xi＇ an Passenger Dedicated Line, German Züblin mechanical construction and artificial construction were used. For the two kinds of construction process, key technology and later operation effect, the technology is summarized and treatment measures for common prob-lems during the construction and later operation are put forward.
