摘要
以新建襄渝铁路二线拆除跨既有线石拱桥施工为实例,介绍了采用搭设带绝缘板的钢结构临时防护拱架,拆除跨既有电气化铁路石拱桥施工技术。施工时确保既有线行车安全,对同类型既有线施工具有借鉴意义。
Based on the example of removing the stone arch bridge across the existing railway in the construction of the newly-built railway fi＇om Xiangfan to Chongqing, this artiele introduces the construction technology of removing stone arch bridge over the existing electrified railway by ereeting steel arch support structure with insulation board to ensure the safety of the existing electrified railway, which can provide reference for the similar projects in the future.
