IRON TOWER LAND SIDE MEMBER CORROSION PREVENTION DEVICE AND METHOD

PROBLEM TO BE SOLVED: To provide an iron tower land side member corrosion prevention device and a method capable of suppressing corrosion-rust development of a land side member of a transmission line tower.SOLUTION: A corrosion prevention device 10 comprises a body 11 for forming a discharge port 11a on an undersurface, first and second wind taking-in parts 12A and 12B provided on the body 1 and taking wind in the body 11 from the two directions, a rainwater taking-in part 13 provided in an upper part of the body 11 and taking rainwater of flowing down by going along an outer surface of a main column material 3 of a transmission line tower in the body 11 and a fixture 15 for installing the corrosion prevention device 10 on the inside of the main column material 3 of an iron tower land side part of the transmission line tower, and the wind taken in the body 11 by the first and second wind taking-in parts 12A and 12B and the rainwater taken in the body 11 by the rainwater taking-in part 13 are blown off downward from the discharge port 11a, so that air permeability of the iron tower land side part is improved, and sediment and fallen leaves are not deposited in the iron tower land side part.SELECTED DRAWING: Figure 1 【課題】送電鉄塔の地際部材の腐食・発錆を抑止することができる鉄塔地際部材腐食防止装置および方法を提供する。【解決手段】腐食防止装置１０は、下面に吐出口１１ａが形成された本体１１と、本体１の上に設けられた、かつ、２方向から風を本体１１内に取り込むための第１および第２の風取込部１２Ａ，１２Ｂと、本体１１の上部に設けられるとともに送電鉄塔の主柱材３の外面を伝わって流れ落ちる雨水を本体１１内に取り込むための雨水取込部１３と、腐食防止装置１０を送電鉄塔の鉄塔地際部の主柱材３の内側に取り付けるための取付具１５とを具備し、第１および第２の風取込部１２Ａ，１２Ｂで本体１１内に取り込んだ風および雨水取込部１３で本体１１内に取り込んだ雨水を吐出口１１ａから下方に向けて吹き出すことにより、鉄塔地際部の通気性を良くするとともに鉄塔地際部に土砂や落ち葉等を堆積させないようにしている。【選択図】図１
