摘　　要：为解决跨越电化铁路桥梁改造施工中铁路“天窗”时间短、施工干扰大、施工空间狭窄、安全防护难度大等难题,文章针对南浦立交桥改造工程跨越4条繁忙铁路干线和1条专用线桥梁改造施工,提出了一种可移动吊装防护施工作业平台方法,从而避免了拆除电化设备和长时间的既有线施工作业,减小了对哈齐高速铁路及平齐电化铁路的影响,解决了公路、铁路施工安全防护问题,有效提高了“天窗”时间利用率,以期为相关工程提供借鉴。In order to solve the problems of short railway“skylight”time,large construction interference,narrow construction space,and difficult safety protection in the construction of bridge renovation across electrified railways,this article proposes a movable lifting and protection construction platform method for the Nanpu Overpass Bridge Renovation Project,which spans four busy railway trunk lines and one dedicated line bridge renovation.This avoids the dismantling of electrified equipment and long-term construction operations on existing lines,reduces the impact on the Haqi high-speed railway and Pingqi electrified railway,solves the safety protection problems of highway and railway construction,effectively improves the utilization rate of“skylight”time,and provides reference for related projects.
