180min天窗一步到位更换接触网承力索和接触线施工工艺

Construction Process for One-step Replacement of OCS Catenary and Contact Wire During 180min Window

随着我国铁路建设持续发展,既有电气化铁路接触网换线改造项目日益增多。为解决既有铁路接触网改造施工与日常运输之间的矛盾,提高接触网改造施工天窗利用率,以确保在运营线路安全、优质、高效地完成施工任务,并更好地适应灵活多变的施工要求,结合京原铁路工程实践,从施工组织方式和施工工艺等方面,提出相关改进优化措施。

With the continuous development of railway construction in China, there are more and more OCS line replacement and upgrade projects of existing electrified railways. In order to solve the contradiction between the OCS upgrade of the existing railway and daily transportation, improve the utilization rate of the construction window for the OCS upgrade to ensure that the construction tasks can be completed with safety, quality and efficiency in the operation line, and better adapt to the flexible construction requirements, in combination with the engineering practice of Beijing-Yuanping Railway, relevant improvement and innovation measures are put forward in terms of the construction organization mode and the adoption of new construction technology.
