摘要
在电网建设架空输电线路架线施工过程中,跨越高速铁路是近年来输电线路张力放线施工过程中遇到的新课题.介绍了利用本塔辅助横担封网跨越高速铁路的施工方法.该方法在500 kV输电线路工程跨越运行的高速铁路中采用并顺利实施,在国内外500 kV输电线路跨越高速铁路中采用该方法的尚无先例.依据该方法首例顺利实施所取得的经验对该跨越施工方法进行探讨,为后续电网工程建设提供一定的借鉴和指导.
Abstract
With the continuous power grid construction,crossing the high-speed railway is a new problem during the overhead transmission line construction in recent years.This paper describes the construction method of using the auxiliary crossarm installed on the original tower and insulation protective net for crossing high-speed railway.This method has been successfully implemented in the 500kV transmission line crossing the running high-speed railway.This unprecedented method has not been used in the domestic and overseas engineering.This method is discussed based on the first successful implementation experience,providing reference and guidance for the future grid construction.
