摘要： PURPOSE:To provide a system, in which lowering of pH at the surface part of an electrode is restrained and also contact of the generated gas with the electrode is restrained by diffusing the gas into the ground so as to extend the service life of the electrode, by positively supplying liquid to the near part of the electrode. CONSTITUTION:A liquid supplying pipe 9 is arranged near the electrode 3 for corrosion protection and the liquid is supplied to the near part of the electrode 3 from a liquid supplying device 10 through the liquid supplying pipe 9. By supplying this liquid, the lowering of the pH at the near part of the electrode is relaxed and further, the gas generated from the electrode 3 for corrosion resistance is diffused to the surroundings of this electrode 3 by the supplying pressure of this liquid to prevent the contact of the gas with the electrode 3. By this method, the deterioration of the electrode 3 is restrained and the cathode corrosion protection of a metal to prevent the corrosion is attained without executing the exchange or the repair of the electrode 3 for corrosion protection for a long period.

摘要： PURPOSE:To perform replacement and repair of an anode at an optimum timing by measuring potential difference between the anode and an electrode for monitor with the elapse of time while allowing fine current to flow to the electrode for potential monitor having constant potential. CONSTITUTION:A corrosionproof body 2 to be protected is made anticorrosive by conducting electricity between an anode 6 for anticorrosion provided in the soil or underwater and the corrosionproof body 2 to be protected. The potential difference between the anode 6 and an electrode 10 for monitor is measured by a potential difference detector 13 with the elapse of time while allowing fine current to flow to the electrode 10 for potential monitor having nearly constant potential. Thereby the potential of the anode is detected. Therefore replacement and repair of the anode can be performed at an optimum timing.

摘要： PURPOSE:To extend a place to which an electrode body is applicable as well as to improve the workability by making it possible to easily attach the electrode body even to the vertical surface, the bottom or a narrow spot of a concrete structure. CONSTITUTION:Joining members 2 are fixed on a concrete structure and an electrode member 5 is fixed in the joining members 2. A back filler 6 is filled into a support vessel 3 having an opening, and the vessel 3 is joined to the joining members 2 so that the opening confronts the surface of the concrete structure. By the joining, the back filler 6 is pressed against the surface of the concrete structure. Thus, an electrode body 1 consisting of the joining members 2, the electrode member 5, the support vessel 3 and the back filler 6 is attached to the cencrete structure.

SOLUTION: A sliver and a silver chloride electrodes coated by silver chloride layer on the surface of a silver base connecting to a positive terminal and a negative terminal of a power source device are dipped in water solution containing chloride ion with a specific distance. By impressing voltage in the power source device, a weak signal with small distortion is generated between the negative and the positive electrodes. This silver and silver chloride electrodes are produced, for example, by applying chemical polishing or electrolytic polishing on a machined silver base, electrolytic-oxidizing in solution containing chloride ion and chloridizing the surface layer of the silver base.

摘要： PURPOSE: To remove the tip of an anchor from a head by utilizing a reaction a jig receives, and to pull out the anchor from the hole of a concrete structure, by screwing a base to the anchor, and squeezing the projection at the tip of the jig to the tip of the head through the hollow of the anchor. CONSTITUTION: An anchor 1 is driven in to the hole 3 of a concrete structure, the tip of the anchor is expanded by a head 2, and the irregular surface 1b on the outer surface of the tip is fixed solidly with the wall surface of the hole 3. In this case, when the anchor 1 is removed, the male screw 4a of a jig 4 is screwed to the female screw 1a of the anchor 1, so as to advance the jig 4, and the tip of the projection 4b of the jig 4 is abutted to a head 2. Furthermore, the head 2 is squeezed to the bottom of the hole 3, and the anchor 1 is pulled out from the head 2 by receiving the reaction of the head 2. As a result, the tip of the anchor 1 expanded by the head is contracted, and the anchor is separated from the wall surface of the hole 3 of the concrete structure. Then a friction force between the wall surface and the irregular surface of the tip of the anchor 1 is eliminated, and the anchor 1 is picked out from the hole 3 easily by the jig 4.
