Zusammenfassung:PROBLEM TO BE SOLVED: To provide a removal method of an overhead transmission line capable of removing the overhead transmission line, while preventing an anticorrosive agent from scattering reliably.SOLUTION: A removal method of an overhead transmission line is a removal work method of an overhead transmission line (10) and has a step for winding a first anticorrosive agent scattering prevention tape (11) in the reverse direction (Z twist direction) of the twisting direction (S twist direction) of the outermost layer (10a) of the overhead transmission line (10). When winding the first anticorrosive agent scattering prevention tape (11) in the reverse direction (Z twist direction) of the twisting direction (S twist direction) of the outermost layer (10a) of an existing overhead transmission line (10), dropping of the anticorrosive agent from the wire surface and dropping of the anticorrosive agent in the wire due to turning of the wire twist in the loosening (laughing direction) can be relaxed, and the overhead transmission line can be removed while preventing the anticorrosive agent from scattering reliably.SELECTED DRAWING: Figure 1 【課題】防食剤が飛散することを確実に防止しながら架空送電線を撤去することが可能な架空送電線の撤去方法を提供する。【解決手段】架空送電線の撤去方法は、架空送電線(10)を撤去する架空送電線の撤去工事工法であって、第1の防食剤飛散防止用テープ(11)を、架空送電線(10)の最外層(10a)の撚り方向(S撚り方向)と逆方向(Z撚り方向)に巻き付けるステップを有することを特徴とする。このように既設の架空送電線(10)の最外層(10a)の素線撚り方向(S撚り方向)と逆方向(Z撚り方向)に第1の防食剤飛散防止用テープ(11)を巻き付けることにより、電線撚りが緩む(笑う)方向に回転し、電線表面の防食剤および電線内部の防食剤が落下しやすくなってしまうのを緩和することが可能となり、防食剤が飛散することを確実に防止しながら架空送電線を撤去することが可能となる。【選択図】図1
