Accuracy Control of Paving of CRTSⅡ Ballastless Track Slab on Passenger Dedicated Line

CRTSⅡ型轨道板的铺设精度是无砟轨道铁路的一道关键工序,控制好轨道板铺设精度,不仅能保证铁路的高平顺性,也能降低工程成本。结合在京石无砟轨道施工中的工程实践,通过对轨道板铺设各工序中影响铺设精度的因素的分析,提出了相应的控制措施。

The paving accuracy for CRTS II slab is one of the most important procedures in ballastless track construction.Controlling paving accuracy will not only guarantee a smooth railway,but also reduce the construction cost.Using experience from Beijing-Shijiazhuang passenger dedicated line construction,this paper discusses factors affecting the accuracy of paving ballastless track and suggests corresponding measures.It is hoped that this paper can provide some reference for CRTS II ballastless track slab construction.
