CRTSⅡ型板式无砟轨道无缝线路换板施工技术

摘要

Based on the practice of plate change of CRTS Ⅱ ballastless track slab on a high-speed rail passenger line bridge in curve location,this article summarizes a set of well developed construction technology.The techniques avoids the seamless rail line cutting,loosening the fasteners,turning away from rail ballast and other processes,which save construction time and reduce the economic loss,and it is well worth promotion in the future slab change of CRTS Ⅱ ballastless track slab.%通过对某高铁客运专线特大桥桥梁在曲线位置的CRTSⅡ型板式无砟轨道轨道板换板实践进行总结,形成了一套成熟的施工技术。该技术避免了对无缝钢轨长线切割、钢轨长线扣件松脱、钢轨翻离道床等工序,节约了大量的施工时间,同时减少了经济损失,可以在今后的铁路工程CRTSⅡ型板式无砟轨道轨道板换板施工中推广应用。
