Abstract

The invention relates to marine concrete ecological engineering, particularly to a method for constructing an ecological high-durability concrete structure in a marine environment, and belongs to thefield of marine ecological engineering. The construction method comprises the following steps: (1) investigating the sea area of a construction position of a concrete structure; (2) culturing oyster eyelid larvae; (3) constructing the concrete structure; (4) carrying out field attachment; and (5) monitoring larva attachment and management. According to the invention, a novel anti-corrosion technology of marine fixation organisms is adopted, so that the durability of reinforced concrete can be greatly improved, the ecological environment of the sea area is improved, the current situation that the ecological environment is damaged by constructing concrete engineering is changed, and the damaged ecological environment can be repaired.

Description

technical field [0001] The invention relates to a marine concrete ecological engineering, in particular to a method for constructing an ecological high-durability concrete structure in a marine environment, and belongs to the field of marine ecological engineering. Background technique [0002] The ocean is not only a treasure house of human resources, but also a natural corrosive environment. In marine concrete structures, the corrosion of steel bars caused by chloride ion attack greatly reduces the durability of concrete. In order to improve the durability of concrete and thus increase the service life of marine concrete structures, scholars and technicians have proposed anti-corrosion measures such as high-performance concrete, surface coating, FRP bars, steel bar rust inhibitors, and electrochemical protection technologies. However, these anti-corrosion technologies all have one or more of the disadvantages of difficult construction, easy aging of materials, insufficien...
