500kV输电线路两柱式钢管塔施工

Construction of 2-Column Type Tubular Steel Tower for 500 kV Lines

500kV双回华电芜湖电厂送出工程输电线路全长约105km,其中当涂县黄池镇规划区境内共18基采用钢管塔,沿线均位于河网地带的农田中,单节长且重,运输和施工十分困难。实践证明,运输道路较差、吊车无法进入塔位的两柱式钢管塔采用□800落地抱杆分解组立的方法,不失为一种有效、经济的施工方法。

The 105-km-long 500 kV double-circuit output line of Huadian Wuhu Power Plant has 18 tubular steel towers built within Huangchi, Dangtu County, which are all located in river zone farmland, and each section is long and heavy, resulting in difficulties in transportation and construction. It has been proved through practices that to 2-column type tubular steel towers in places inaccessible by cranes, assembling by parts through square type800 lifiug pole is an effective and economic way.
