铁路无缝线路应力放散与锁定技术研究

Rail Stress Relief Pipe and Seamless Locking Technology Research

无缝线路技术是重要的轨道结构新技术,无缝线路应力放散和锁定是新建无缝线路的一项重要工作内容,也是运营线路工务部门必做的工作之一。近年来,随着铁路行业的大力发展,无缝线路已经成为主导线路,而应力放散和锁定是无缝线路必须使用的一项施工工艺,其施工水平直接影响着施工进度和施工安全。通过对无缝线路应力放散的条件、方法、质量控制、线路锁定的温度时机等进行分析研究,得出了宝贵的施工经验。

Seamless line technology is an important new technology of track structure, stress relief pipe and seamless lock is an important content in the work of the new seamless lines, is one of the operating line works departments will work. In recent years, with the development of railway industry vigorously, has become the leading line, seamless and stress relief pipe and lock is must use a seamless construction technology, its construction level directly affects the construction progress and construction safety. Through the condition of stress relief pipe seamless, methods, quality control, the temperature of the line lock timing analysis, obtained valuable construction experience.
