In general, artificial reefs are habitats for fish and shellfish and are artificial structures in the sea where algae and other aquatic plants are implanted and planted. The artificial reefs are artificially introduced into structures under the sea or in the sea to collect, protect and cultivate aquatic animals such as fish and shellfish. It refers to a fishing facility for the purpose.

These artificial reefs are mainly installed in waters of 10 to 50 m depth, and provide habitat for protecting fish spawning and living, as well as allowing the implantation of aquatic plants.

The artificial reef, which is a conventional artificial structure, can be largely divided into a type of tetrapod block having an open hole communicating with a type of porous concrete block.

At this time, the porous concrete block-type artificial reefs enable the rapid conception of aquatic plants by the formation of voids, and the tetrapod block-type artificial reefs facilitate the easy habitat of fish and shellfish through the communicating open holes. .

However, the artificial reef of the conventional porous concrete block type has a problem of strength deterioration, such as the compressive strength and the bending strength is reduced because the porous structure formed a plurality of voids in the concrete block.

On the other hand, the tetrapod block-type artificial reef having a conventionally communicated open hole is made of a concrete structure having four protruding legs in one body, and has a structure in which opening holes communicating with each other are opened in the legs of the concrete structure. .
