摘要
500kV贺罗Ⅱ线476号铁塔发生基础下陷,造成杆塔严重倾斜,主材严重弯曲,其中部分斜材被拉裂。经过技术经济分析,选择了一个"校正杆塔、及时恢复送电"的方案,采取"杆塔利用四根抱杆加固、塔腿垫高、更换变形塔材、增加4根临时拉线保护"等措施3天内将铁塔修复。
The No. 476 pylon of the 500 kV Hezhou-Luodong line Ⅱ suffered a serious inclination due to the sedimentation of pylon base. The primary shank was serious bended and some minor slanted struts were ripped apart. Considering the technical and economical aspects, a solution of ＂rectifying pylon and restoring power transmission ASAP＂ is chosen, and with measures of ＂solidified the pylon, underlaid the legs of pylon, replaced the distorted parts and set 4 additional temporary stay wire＂ the pylon is restored within 3 days.
