110kVA超长电力管线架空保护施工技术

PROTECTION CONSTRUCTION TECHNIQUE FOR OVERHEAD 110 kVA SUPER-LONG POWER LINES

当前城市地铁、隧道及管廊等基础设施项目中基坑开挖及主体作业与既有管网的交叉越来越多,不可避免受地下市政管网的影响,西安高新区创业新大陆地下隧道及综合体工程施工过程中,采取多项技术措施对长180m、架空高度19.5m的110kVA超大型高压电缆进行保护,取得了良好的效果。

At present,foundation pit excavation and main body construction of infrastructure projects,such as urban subway line,tunnel and pipe gallery,have more and more cross with existing pipelines,and they are inevitably affected by the underground municipal pipelines.Many technical measures were adopted in the construction of Chuangye Newland underground tunnel and complex building,to protect the 110 kVA super-large high-voltage cable with a length of 180m and an overhead height of 19.5m,achieving favorable effects.
