时速350km铁路道岔板式无砟轨道施工工艺研究

On Construction Technology of Plate-type Ballastless Track for 350km/h Railway Switch

铁路道岔是列车安全运行必须通过的"咽喉"区,高速铁路道岔铺设的平顺性和总体施工质量,更是至关重要,决定着高速列车的平稳通过和安全运行。通过石武客运专线工程的施工实践,进一步探索和研究高速铁路道岔板式无砟轨道的施工工艺,使其不断完善和成熟,较好地实现道岔铺设的平顺性,保证工程总体质量,取得一定效果。

he railway switch is a ＂throat＂ for the running of trains. The smoothness and overall construction quality of the laying of high-speed railway switch guarantee the successful passing and safe running of high-speed trains. Through construction practice of Shijiazhuang-Wuhan passenger line project, this paper further explores, researches and improves the construction technology of plate-type ballastless track for high-speed railway switch, which better realizes the smoothness of switch laying, ensures the overall construction quality and achieves a certain effect.
