CORROSION PREVENTION DEVICE AND CORROSION PREVENTION METHOD
PROBLEM TO BE SOLVED: To provide a corrosion prevention device and a corrosion prevention method capable of preventing corrosion of a part of an angle steel close to the ground, which is a main column member of a power line tower vertically installed on a foundation.SOLUTION: Rain water W running down on an outer surface 2b of a main column member 2 reaches a guiding through-hole 8, subsequently reaching an inner surface 2a after passing through the guiding through-hole 8, and drops on a first inclined upper surface 9a of a reinforcement member 9, which is drained along the first inclined upper surface 9a in a direction apart from a part 5 close to the ground, or drops on the first inclined upper surface 9a of the reinforcement member 9 to reach a second inclined upper surface 10a of an inclined concrete material 10, which is drained in a direction apart from the part 5 close to the ground to prevent corrosion on the part 5 close to the ground.SELECTED DRAWING: Figure 1
【課題】 基礎に立設された送電鉄塔の主柱材である山形鋼の、地際部の腐食を防止可能な腐食防止設備、および腐食防止方法の提供。【解決手段】 主柱材２の外面２ｂを伝って落ちてくる雨水Ｗは、貫通誘導孔８に至ると貫通誘導孔８を通過して内面２ａに至り、補強材９の第一傾斜上面９ａに落ち、第一傾斜上面９ａを伝って地際部５から離れる方向へ排出され、あるいは、補強材９の第一傾斜上面９ａに落ちて、傾斜コンクリート材１０の第二傾斜上面１０ａに至り、地際部５から離れる方向へ排出されて、地際部５の腐食が抑制される。【選択図】 図１
