STEEL TOWER REBUILDING METHOD
To provide a steel tower rebuilding method capable of reducing costs and shortening work time in a case of rebuilding a steel tower using an enclosing method.SOLUTION: A steel tower rebuilding method according to the present invention is a steel tower rebuilding method used for the tower rebuilding work for removing the existing steel tower over which a transmission cable is hanged and laid and installing a new steel tower at a position where the existing steel tower was installed, having configuration so as that the existing steel tower has a square shape with four leg portions and four side surfaces, the new steel tower is a square shape with two first and second triangular steel towers with three leg portions, a first triangular steel tower is built on one cable side of the existing steel tower, one cable that the existing steel tower is hanging and laying is moved to the first triangular steel tower, a second triangular steel tower is built on the other cable side of the existing steel tower, the other cable that the existing steel tower is hanging and laying is moved to the second triangular steel tower, and the existing steel tower is removed.SELECTED DRAWING: Figure 2
【課題】包込工法を用いて鉄塔の建替えを行う場合におけるコストの低減および作業時間の短縮を図ることが可能な鉄塔建替工法を提供することを目的とする。【解決手段】本発明にかかる鉄塔建替工法の構成は、送電線を張架する既設鉄塔を撤去し、既設鉄塔が設置されていた位置に新設鉄塔を設置するための鉄塔建替工事に用いる鉄塔建替工法であって、既設鉄塔は、４本の脚部を備え４つの側面を有する四角状であり、新設鉄塔は、３本の脚部を備える第１の三角鉄塔と第２の三角鉄塔を２つあわせて四角状にするものであり、既設鉄塔の一方の回線側に第１の三角鉄塔を建設し、既設鉄塔が張架している一方の回線を第１の三角鉄塔に移設し、既設鉄塔の他方の回線側に第２の三角鉄塔を建設し、既設鉄塔が張架している他方の回線を第２の三角鉄塔に移設し、既設鉄塔を撤去することを特徴とする。【選択図】図２
