青藏铁路格拉段开通运营以来,采用大型养路机械成为线路维护的主要手段。通过分析青藏铁路大型养路机械的维修特点、现状、配置和能力,提出坚持线路能力适度超前和质量必要储备原则,积极推进“预防修”;坚持线路状况动态检测为主和动态静态综合分析维修指导原则,积极推进“状态修”;坚持线路结构等强均衡原则,强化道床和基床管理,积极推行“均衡修”;坚持线路精度绝对值管理原则,先测量,后作业,积极推行“精确修”。为提高大型养路机械作业质量,提出开展作业试验分析,创新施工理念,探索先进的作业方式,以及大型养路机械优先配置的原则和建议。
Since the opening of the Qinghai-Tibet Railway Ge La segment operation, the use of large-scale maintenance machinery has become the main means of line maintenance. By analyzing the maintenance features, status quo, configuration and capability of the large-scale maintenance machinery for the Qinghai-Tibet Railway, the paper puts forward the principle of keeping the line capacity moderately advanced and the quality necessary reserve, proactively advancing “preventive repair ”; insist on dynamic detection of line conditions and dynamic static comprehensive analysis Maintenance guidelines, and actively promote the “state repair ”; adhere to the principle of equal balance of line structure, strengthen bed bed and bed management, and actively promote “balanced repair ”; adhere to the absolute principle of line accuracy management, first measurement, , Actively promote “precise repair ”. In order to improve the operation quality of large-scale maintenance machinery, it is proposed to carry out operation test analysis, innovate construction concept, explore advanced operation methods and give priority to large-scale maintenance machinery.
