Cathode Protection Method and Apparatus for Reinforced Concrete Structure and Composite Structure and Processing Method for Reinforced Concrete Structure

摘要

A cathode protection method of embedded CFRP anode for reinforced concrete structure includes the following steps. Provide a preformed groove with a predetermined shape and size in a surface of a protection area of a reinforced concrete body, and remove dust in the preformed groove. Provide a CFRP member on the surface of the protection area of the reinforced concrete body. Coat an electrical conductive adhesive material between side surfaces of the reinforcing column of the CFRP member and the preformed groove and between the reinforcing plate and the reinforced concrete body. Connect the CFRP member with a positive electrode of an external DC power supply and the steel reinforcing element with a negative electrode of the external DC power supply.

1. A cathode protection method of embedded CFRP anode for reinforced concrete structure, comprising the steps of:
(a) providing a preformed groove with a predetermined shape and size in a surface of a protection area of a reinforced concrete body, and removing dust in said preformed groove; (b) providing a CFRP member on said surface of said protection area of said reinforced concrete body, wherein said CFRP member comprises a reinforcing column shaped and sized with respect to said preformed groove and at least at least a reinforcing plate integrally connected with said reinforcing column and affixed on said surface of said protection area of said reinforced concrete body; (c) coating an adhesive material with electrical conductive ability on side surfaces of said reinforcing column of said CRFP member and said preformed groove of said reinforced concrete body to be connected with other and between said reinforcing plate and said reinforced concrete body, so as to embed said reinforcing column in said preformed groove of said reinforced concrete body and connect said reinforcing plate with said reinforced concrete body; 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 reinforced concrete body, said CFRP member and said external DC power supply to form a close electrical conductive circuit.
