东非既有米轨铁路轨道修复施工方法及验收标准研究

Research on Track Repair Construction Method and Acceptance Criteria of Existing Meter Gauge Railway in East Africa

东非地区米轨铁路修复施工不同于国内既有铁路的大修工程,一是既有米轨铁路处于废弃及半废弃状态,修复难度大。二是当地近百年未进行铁路建设,铁路相关产业空白,没有相关国家或行业标准、规范等,施工缺乏参照标准。文章以乌干达米轨铁路为例,根据其线路状况及乌干达国情,采取修复施工的主要方法,制定修复过程中的关键控制指标,以确保铁路线路的畅通运行,提高火车运行效率。

The repair construction of meter gauge railway in East Africa is different from the major repair project of existing railways in China.Firstly,the existing meter gauge railway is in a state of abandonment and semi-abandonment,making repair very difficult.Secondly,there has been no railway construction in the local area for nearly a hundred years,the railway related industry is blank,there are no relevant national or industry standards,norms,etc.,and the construction lacks reference standards.Taking Uganda meter gauge railway as an example,according to its line conditions and Uganda's national conditions,this paper adopts the main methods of repair construction,and formulates key control indicators in the repair process,so as to ensure the smooth operation of railway line and improve the efficiency of train operation.
