构建线路质量保障体系 确保提速线路持续稳定

Build up the Quality-Security System of Track and Ensure Sustaining Stability of Speed-up Lines

南昌铁路局管内沪昆线是全路第六次大提速线路改造中任务最重、养护维修难度最大的线路。南昌铁路局主要通过运用三维精测定位系统、强化断面控制,建立严格的检查监控模式、强化对线路状态的严密监控,建立养护维修新机制、强化线路质量动态保持等措施,建立适应时速200km要求的线路质量保障体系,并取得了成效。

The section of Shanghai-Kunming line in the terriitory of Nanchang Railway Administration is the one with the heaviest workload and the greatest maintenance difficulties during the upgrading for the sixth round speed-up campaign of China Railways. Nanchang Railway Administration has built up a quality security system that meets requirements of lines with running speed of 200km/h and has produced evident effect by taking measures of employing three-dimensional accu- rate positioning system to strengthen control over cross-section of track, building strict inspection and monitoring mode to enhance close monitoring of track state, and establishing a new maintenance mechanism to consolidate dynamic maintain- ing of track quality.
