摘要:
无砟轨道结构优势明显，自遂渝试验段成功运营后，在我国得到了广泛的推广和应用。但近年来，时有发生的线下基础变形等问题也给无砟轨道的维修工作带来了一些困扰，尤其是基础发生上拱变形的问题。为解决此类问题，文章以某铁路隧道上拱病害段无砟轨道的整治为例，提出了一个维修天窗期间无砟轨道拆换的技术方案。从施工准备和天窗作业两个主要方面着手，阐述并探讨了测量方法、数据分析、轨道状态调查、轨道结构拆换工序等关键技术及流程，为运营铁路利用天窗期整治该类无砟轨道病害提供了一种有效的技术措施。
Abstract:
Since the test section of Suining-Chongqing railway was put into use, the ballastless track has been greatly popularized and applied in China because of its obvious structural advantage. in recent years, some problems such as foundation deformation, etc. bring some difficulties to maintenance work. Therefore, in this paper, a technique scheme of ballastless track replacement during maintenance time is put forward, the key technologies such as measuring method, data analysis, track state investigation and track structure replacement, etc. are expounded and discussed from construction preparation and maintenance time, which provides an effective technical measure for diseases repairing of ballastless track of railway in operation during maintenance time.
