Cathode Protection Method for Reinforced Concrete Structure and Apparatus Therefor

摘要

A cathode protection method for reinforced concrete structure includes steps of: a. removing loose concrete within a protection area, and filling adhesive materials with conductive ability into cracks of a concrete; b. implanting CFRP member as a impressed current auxiliary anode material into the concrete, and spacedly arranged the CFRP member with steel reinforcing elements within the concrete; c. coating adhesive materials on a side of the CFRP member, and firmly pressing the adhesive materials to bonding the CFRP member and the concrete with each other; and d. electrically connecting the steel reinforcing elements and the CFRP member to a negative electrode and a positive electrode of an external DC power supply respectively, such that the concrete, the steel reinforcing element, the CFRP member, and the external DC power supply generate serially-close conductive circuit.

1. A cathode protection method for reinforced concrete structure, comprising steps of:
A. removing loose concrete within a protection area, and filling an adhesive material with conductive ability into cracks of a concrete; B. implanting a CFRP member as an impressed current auxiliary anode material into said concrete, and spacedly arranged said CFRP member with steel reinforcing elements within said concrete; C. coating said adhesive material on a surface of said CFRP member facing towards said steel reinforcing element, and firmly pressing said adhesive material to adhere said CFRP member and said concrete with each other; and D. connecting said CFRP member with a positive electrode of an external DC power supply and connecting at least a steel reinforcing element in said reinforced concrete body with a negative electrode of said external DC power supply, wherein said steel reinforcing element and said adhesive material are electrically connected via said concrete, said CFRP member and said external DC power supply to form a close electrical conductive circuit.
