Method and device for strengthening reinforced concrete structure with cathode protection function

Abstract

The invention discloses a method and device for strengthening a reinforced concrete structure with a cathode protection function. The method comprises the steps of: chipping loosen concrete at the strengthening area of a reinforced concrete structure body, and polishing smoothly; arranging a CFRP (Carbon Fiber Reinforced Plastics) sheet on the surface of the strengthening area of the reinforced concrete structure body; electrically connecting a plurality of main reinforcements buried in the strengthening area of the reinforced concrete structure body; and connecting an external power supply for applying cathode protection to the main reinforcements between the main reinforcements and the CFRP sheet, and regulating the size of protective current to the reinforcements through a control device and a detection device in a circuit. Therefore, the reinforcements can be protected while the structure bearing capacity is improved, the problems of secondary corrosion and repeated repair and damages can be avoided, and the security and durability of the structure can be enhanced.

Description

technical field [0001] The invention relates to the field of reinforced concrete structure reinforcement, in particular to a reinforced concrete structure reinforcement method and device with cathodic protection function. Background technique [0002] Reinforced concrete structure is the most important structural form in civil engineering, and its safety is closely related to the healthy development of the national economy. However, with the increase of the service life and the change of the service environment, the deterioration and functional failure of reinforced concrete structures are more common and serious, which has aroused the attention of scientific researchers on the durability of concrete structures. In short, the durability of concrete refers to the ability of concrete to resist various destructive factors under actual use conditions and maintain the integrity of strength and appearance for a long time. [0003] From the point of view of materials science, the ...
