The present invention relates to a method of protecting reinforcing reinforcing bars 2 of utility poles from galvanic corrosion using galvanic anode material 6.
（イ）、第１図のコンクリート電柱１の根入れ深さ８部

はボールト等５に電気的に接続する。(a), The concrete utility pole 1 in Fig. 1 has a penetration depth of 8, Fig. 2 of the A-A cross section, Fig. 3 of the C-C cross section, and B-
As shown in FIG. 4 of cross section B, a metal material 3 in the form of a rod or strip for forming a ground electrode is embedded in the concrete outer wall of the outer periphery of the utility pole, a ground conductor 4 is connected, and a conductor for an extraction terminal or a vault, etc. electrically connected to 5.
本電柱１を大地９に建柱して、使用状態にすると、地中
の湿度によって、コンクリートの比抵抗は小さくなり、
接地極形成材３と大地９は直接に相互が接触したと同程

極としての機能を発揮させることができる。When this utility pole 1 is erected on the ground 9 and put into use, the specific resistance of the concrete decreases due to the humidity in the ground.
The ground electrode forming material 3 and the earth 9 are in contact with each other with the same electrical resistance as if they were in direct contact with each other, and can automatically function as a ground electrode.

Elutes and corrodes.
この様な腐食を防止するため、■２図及び■４図に示す
ように、鉄材２より自然電位の低い亜鉛、アルミニウム
、マグネシウム等のような流電陽極６を、電柱の地中埋
設深さ範囲８内の底面又は側面に埋め込みし、導線７に
よって補強鉄筋材こと電気的に接続する。In order to prevent this kind of corrosion, as shown in Figures 2 and 4, galvanic anodes 6 made of zinc, aluminum, magnesium, etc., which have a lower natural potential than the iron material 2, are buried at the depth of the underground poles. It is embedded in the bottom or side surface within the range 8 and is electrically connected to the reinforcing reinforcing bar material using the conductor wire 7.

鉄筋が溶出するのを防止する流電陽極式電気防食法回路
が自然に形成される。When a utility pole is used in this way, the underground part of the concrete absorbs moisture and becomes highly conductive, and through the concrete, the electric current ■ flows through the arrow 10 as shown in the equivalent circuit in the figure.
Flows from the (-) side to the (+) side through the conductor 7, as shown in
A galvanic anode cathodic protection circuit is naturally formed to prevent reinforcing steel from leaching out.
以上のように防蝕すると、コンクリート電柱の耐用年数
低下を防止することができる。Corrosion prevention as described above can prevent a decrease in the service life of concrete utility poles.
