大跨度防电棚搭设施工技术

On construction technique of large-span electricity defense canopy erection

结合湘桂线衡阳—永州段扩能改造工程周家坳特大桥连续梁工程施工实例,探讨了跨越站场大跨度防电棚施工技术,对防电棚支架体系搭设、过轨施工技术、安全处理措施等做了分析和研究,为类似工程施工提供了一定的指导和借鉴。

Combining with the construction examples of the continuous beam project at Zhoujia＇ao Super Bridge in the capacity expansion project at Hengyang to Yongzhou section along Hengyang-Youyiguan railway,the study explores the construction technique of the large-span electricity defense canopy crossing the station field and analyzes and researches the erection of the support system of the electricity defense canopy,the rail-transferring construction technique and the safety treatment measures,so as to provide some direction and reference for similar projects.
