PURPOSE:To give uniform anticorrosive effect to the longitudinal direction of metal boy by digging a shaft so as to expose a part of burried long metal body and by inserting a bar-like anode along the metal body through the shaft for electrically connecting the both. CONSTITUTION:The shaft 3 is digged to a depth at which a part of the metal body 1 is exposed at any point in the longitudinal direction of the burried long metal body, and then the bar-like anode 2 is inserted along the metal body by using the pusher 4. Then, the metal body 1 and the anode 2 are connected electrically through the lead wire 5 and then the shaft 3 is filled up. Since this anode bar 2 is continuous, uniform and sufficient anticorrosive effect can be obtained, thus permitting predetermined anticorrosive work to be obtained easily. |
