随着社会经济的不断发展,人们对出行的要求也越来越高。目前,铁路运输已经进入高速时代,为了满足高速列车运行时平稳的需求,全部高铁正线均建成无砟轨道高速道岔。但是无砟轨道长枕埋入式高速道岔的施工工艺比较复杂,因此本文主要以合福客专的无砟道岔铺设作为例子,探讨长枕埋入式高速道岔施工技术特点及工艺流程,总结施工经验,以供同行参考应用。
With the continuous development of social economy, people’s requirements for travel are also getting higher and higher. At present, rail transport has entered a high-speed era. In order to meet the steady demand of high-speed trains, all the high-speed rail lines are built into ballastless high-speed turnouts. However, the construction process of ballastless long sleeper buried high-speed turnout is rather complicated. Therefore, this paper mainly takes the laying of ballastless turnout as a example to discuss the construction technical features and process flow of long-sleeved buried high-speed turnout, summarizes the construction Experience for peer reference applications.
