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 surely perform electrolytic protection of a duct or pipe connected to an iron reinforcing bar in a reinforced concrete structure by enclosing most of the region of the structure kept in contact with earth or water with electrifiers for vanishing macro-cells and by supplying electric current to the entire region kept in contact with earth or water. CONSTITUTION:In order to perform electrolytic protection of a duct or pipe 1 connected to an iron reinforcing bar 5 in a reinforced concrete structure 4, many electrifiers 2 for vanishing macro-cells are arranged so that most of the region of the structure 4 kept in contact with earth or water is enclosed with the electrifiers 2. An electrifying anode 13 is then placed so that the duct or pipe 1 and the bar 5 act as a counter electrode and electric current 20 for electrolytic protection is supplied to the entire region of the structure 4 kept in contact with earth or water. Macro-cell voltage Ec is minimized, contact resistance Rc is relatively increased and the dispersion of the electric current 20 is prevented to inhibit the corrosion of the duct or pipe 1.

摘要： PURPOSE:To detect the protective potential approximate to the true value of an object to be electrolytically protected by attaching a probe consisting of a small leaf of the material equiv. to the material of the object to be electrolytically protected and an electrical insulating material to said object and interrupting the connection between both. CONSTITUTION:Protective current 5 is passed between a buried and coated pipe 1 and an underground energizing electrode 4 from an electrolytic protective power supply device 3 to protect a holiday 6 of the coated pipe 1. The probe 7 consisting of the small leaf consisting of substantially the same material as the material of the coated pipe 1 and the electrical insulating material is stuck to the coated pipe 1 by an adhesive agent 15 in such a manner that the surface of the small leaf is in parallel with the surface of the coated pipe 1 and faces the same direction. The connection of the probe 7 and the coated pipe 1 is thereafter interrupted by an interrupter 13 and the potential difference between the probe 7 and a reference electrode 8 is read by a voltmeter 10. The protective current 5 of the holiday 6 and the probe current 5' are thereby maintained under nearly the same conditions and the protective potential approximate to the true protective potential is detected.

摘要： PURPOSE:To easily carry out the electrolytic protection of a pipe buried underground and to easily detect corrosion and electrolytic protection by drilling a hole in a concrete wall in the earth near the part where the pipe pierces through the wall, properly combining an electrode for supplying electric current, a reference electrode, a probe for detecting corrosion and electrolytic protection, etc., and fitting them in the hole in a projecting state. CONSTITUTION:A pipe 2 buried underground pierces through the concrete wall of a reinforced concrete structure 1 having iron reinforcing bars 3. A hole 7 is drilled in the wall in the earth near the part where the pipe pierces through the wall. A tubular assembly 9 for electrolytic protection is fitted in the hole 7 in a projecting state and fixed in the concrete wall. The assembly 9 is composed of 1-3 kinds of components such as an electrode 12 for supplying electric current, a reference electrode 11 and a probe 10 for detecting corrosion and electrolytic protection so as to enable the supply of electric current, the measurement of electric potential and the monitoring of corrosion and electrolytic protection. Thus, the electrolytic protection of the pipe 2 buried underground is carried out.

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.

摘要： PURPOSE: To allow a much significant effect to be shown as compared with a conventional method by surely holding plural metallic bodies in a superimposed state by adhesion so that electric conduction is ensured in the superimposing direction.
CONSTITUTION: An electrically conductive adhesive 11 is applied to both sides of foil 12 of a metal such as stainless steel, Al, Cu or Zn, and the adhesive 11 is coated with strippable paper 10 as a protector. A part of the bottom plate 9 of a seawater storage tank corresponding to the metallic foil 12 is polished, and the foil 12 is adhered to the polished part of the plate 9 with the adhesive 11 after stripping the paper 10. A corrosion preventing zinc plate 1 similar in shape to the foil 12 is then adhered to the foil 12 with the adhesive 11.
