Corrosion-resistant concrete structure of a sea-crossing bridge

Abstract

The invention discloses an anticorrosion concrete structure of a sea-crossing bridge, and belongs to the field of architecture. The anti-corrosion concrete structure of a sea-crossing bridge includesconcrete, A first reinforcing steel plate and a second reinforcing steel plate are connected to the outside of the concrete, A plurality of third reinforcing steel plates are connected between the first reinforcing steel plate and the second reinforcing steel plate, A plurality of the third reinforcing steel plates divide the concrete into a plurality of pieces, A low end of that second reinforcing steel plate is coat with a coating, A surface of that coat is coated with an adhesive coat, A low end of that second reinforcing steel plate is connected with a corrosion-resistant foam plate through an adhesive coating, A low end of that corrosion-resistant foam plate is connected with a self-detachment type lure attachment, the self-detachment type luring attachment induces marine microorganisms to attach centrally, and then the attache marine microorganisms are detached into the sea in a self-detachment manner, thereby greatly reducing the bridge damage caused by the adhesion of marine microorganisms on the coating.

Description

technical field [0001] The invention relates to the construction field, and more specifically relates to an anti-corrosion concrete structure of a sea-crossing bridge. Background technique [0002] In the marine environment, the corrosion of steel bars caused by chloride ion corrosion and the decrease in the durability of marine engineering concrete structures have attracted great attention from the marine engineering community. At present, effective methods to improve the durability of reinforced concrete in the marine environment include the use of high-performance concrete, sprayed concrete protective coatings, and coated steel bars. Among them, concrete coating anti-corrosion is an economical and effective method commonly used. In the design of port terminals and sea-crossing bridges in my country, the anti-corrosion requirements of concrete structures are clearly stipulated. [0003] Anti-corrosion coatings for concrete cannot use anti-corrosion coatings for steel stru...

AI Technical Summary

Problems solved by technology

Generally, coatings are used on concrete. Because marine microorganisms adhere to the bottom of the bridge for a long time, they will damage the coating and erode the concrete and steel bars inside, resulting in bubbling. The cracking of concrete will also cause cracking of the coating, which will lead to the failure of the anti-corrosion coating.
