高速铁路道岔是轨道结构的最薄弱部分,是限制列车运行速度的关键设备。结合郑西客运专线无砟道岔施工情况,为进一步优化和完善高速道岔铺设方法,本文对无砟道岔施工的施工技术作了初步的总结探讨,分析了铺设中存在的一些问题,并提出了相应的改进意见,以期对类似工程起指导借鉴作用。 High-speed railway turnout is the weakest part of the track structure is to limit the speed of the train running the key equipment. In order to further optimize and improve the laying method of high-speed turnout, this paper makes a preliminary summary of the construction technology of the turnout construction, analyzes some problems existing in the laying, and puts forward the corresponding problems Improvement suggestions, with a view to similar projects from the guidance role.
