杭甬客专无砟轨道无缝线路敷设施工技术探讨

Jointless Track Laying Construction Technology for Ballastless Track of Hangyong Passenger Dedicated Railway

探讨杭甬客专无砟轨道无缝线路敷设;500 m长轨条之间的现场焊接、锁定及应力放散的研究;通过检测无缝线路的敷设过程中的轨温和锁定轨温,分析确定合理的无缝线路锁定和放散方式,使无缝线路的敷设能满足高速铁路的要求。

The paper discusses of ballastless track laying for passenger dedicated seamless line;it studies the 500 meters long rail welding,locking and distressing.Through the detection of rail temperature and locked rail temperature during seamless track laying,it analyzes and determines the reasonable seamless line locking and releasing means to make seam line laying satisfy the requirement of high speed railway.
