浅谈架线施工索道式跨越电力线施工方法

500 kV天广Ⅳ回输电线路在云南、广西、广东经济发达地区走线,跨越多处电力线路,仅110 kV及以上有42条,其中500 kV线路2条,因此架线施工的难度大大增加。然而,跨越电力线路施工方法及安全技术措施是否得当,将成为本工程安全保障的重点,也是制约工程施工进度的关键工序。文章介绍了采用索道式跨越电力线路施工方法、选材,以及应采取的安全技术措施和应注意的安全事项。

Brief Introduction of the Telpher Type Overhead Line Construction Method Which Spanning the Transmission Line

500 kV Tianshengqiao-Guangzhou IV circuit transmission line has been constructed in economic developed areas of Yunnan,Guangxi,Guangdong province,and spaned several power transmission line,it has 42 lines of 110kV and over it,and among this,it has 2 lines of 500kV,thus made the construction becomemuch more difficult.Therefore whether the construction method and security measures suitable became the emphasis of the security safeguard of this engineering, also it's the crucial procedure that could restrict the schedule of the engineering.The paper introduces some key points of construction technical measures of using telpher type spanning the transmission line,and the relevant security measures that should be adopted.
