Research on the Rectification and Maintenance of Dedicated Railway Line Defects

铁路运输业在国民经济发展中发挥着至关重要的作用。随着工业4.0时代的到来,中国铁路工业不仅完成了工业设计领域的多项技术研发创新,而且在运营管理方面建立了较为完善的管理体系,构建了适合新时代中国经济发展的产业链。然而,随着我国重载技术的发展,列车轴重不断增加,牵引质量不断提高,线路设备长期超负荷运行。轨道几何尺寸难以维护,甚至出现路基下沉、路基变形、曲线侧磨耗、钢轨及其连接件磨损失效等病害,影响列车运行安全。

In the process of national economic development,the railway transport industry plays a vital role.With the arrival of the industry 4.0 era,China's railway industry has not only complete a lot of technological research and development innovation in the field of industrial design,but also establish a relatively complete management system in operation and management,and constructed an industrial chain suitable for the development of China's economy in the new era.However,with the development of heavy-duty technology in China,the train axle load continues to increase,the traction mass continues to increase,and the line equipment equipment operates under long-term overload.The geometric dimensions of the track is difficult to maintain,and there are diseases such as even the subgrade settlement,track bed deformation,curve side wear,rail and its connecting parts wear failure,which affect the safety of train operation.
