高压架空输电线路跨越高铁施工工艺的研究

Research on High-speed Overhead Transmission Lines CrossingHigh-speed Railway Construction Technology

我国高铁技术迅猛发展,高铁运营里程和覆盖面日益扩大。目前我国的高速列车均采用电力驱动方式,铁路线以全封闭或全立交形式为主,因此在架设高压架空输电线路时,常出现需要跨越高铁的情况。对此,高压架空输电线路架设对安全施工的要求很高,这就对高压架空输电线路的架设技术提出了新的问题和研究方向。本文通过对高压架空输电线路的架设进行研究,总结高压架空输电线路跨越高铁的施工工艺和注意要点,为今后的高压架空输电线路跨越高铁架设提供技术支持。

With the rapid development of China’s high-speed rail technology,the mileage and coverage of high-speed rail are expanding.At present,China’s high-speed trains are driven by electric drive.The railway system is mainly closed or fully interchanged.Therefore,high-voltage overhead transmission lines are set up.At times,there is often a need to cross the high-speed rail.In this regard,the requirements for safe construction of high-voltage overhead transmission lines are high,which raises new problems and research directions for the erection technology of high-voltage overhead transmission lines in China.Through the research on the erection of highvoltage overhead transmission lines,the construction technology and attention points of high-voltage overhead transmission lines crossing the high-speed railway are summarized,which provides technical summary and support for the future erection of high-voltage overhead transmission lines across the high-speed railway.
