Description

Corrosion-resistant marine artificial fish reef

Technical Field

In fact, although the ocean area is very wide, many sea areas are barren of organic matters and are not suitable for the survival of marine organisms, so that the phenomenon that the coral reef with the area less than 0.1% of the ocean area provides a living home for 25% of the marine organisms occurs. The coral reefs facilitate the adsorption and survival of organisms such as algae, conchs and the like, and further form habitat sites for the organisms such as fishes and shrimps and the like to induce the fishes and shrimps and the like to breed. Therefore, the artificial reef is an effective measure for solving the problems, and people put in stones, trees, abandoned vehicles and vessels, tires, concrete prefabricated bodies and the like in proper sea areas to play a role similar to a coral reef as the artificial reef.

The construction of artificial fish reefs has been carried out in coastal areas in the early 80 s in China, and good effects are achieved. At present, most artificial fish reefs are precast structures formed by concrete pouring, and have the advantages of being simple in manufacturing, low in cost and the like. However, since the concrete contains a large amount of alkaline substances, the alkaline substances are continuously released within a period of time after the concrete is put into the ocean, thus affecting the settlement and survival of marine organisms, and since the seawater contains a large amount of chloride ions and the scouring action of ocean currents, the concrete is corroded, and the service life of the concrete artificial fish reef is affected.
