Breakwaters are built in coasts and harbors, and the breakwaters act to attenuate the waves as the waves from the open sea collide with each other, and ships and other facilities anchored on the inland sea can minimize damage caused by the waves.

In general, the sofa block is a deformed concrete block designed to absorb the energy of the wave, and is installed in a place where a wave breaker or a lake receives a large wave to prevent wave attenuation or reflection wave generation. As such a sofa block, a tetrapod, a hexagon block, a tertahedron block, a hollow square, an arch tribar, and the like are used. The sofa block has to satisfy the sofa function and economic aspects of the waves evenly, the conventional sofa block has a disadvantage that the sofa performance is not satisfactory and the transport or construction is not easy compared to the size of the block.

The conventional breakwater is installed at a height capable of preventing a certain high wave, so that the section where the breakwater is installed is blocked from the inland and the outer sea. However, by constructing the breakwater in the form of confining the sea water, since the inflow and outflow of the sea water is not made smoothly, various wastes accumulate on the inner sea side, contaminating the sea water, there is a problem that the odor occurs, which causes the ecosystem on the inner sea side There was a problem that was destroyed.

Moreover, a large repulsion force is generated in the seawater hit the breakwater and the seawater coming in succession is combined to hit the breakwater with greater energy, as a result of the digging is getting higher, there is a problem that the so-called overflow over the breakwater occurs.

On the other hand, artificial reefs generally refer to artificial structures that are installed in the sea to provide hideouts, habitats, or spawning places for coastal mesmerizing fishes and fish and shellfish inhabiting the offshore.

Such artificial reefs have been produced in the form of spherical and polyhedrons using concrete or steel, but in recent years, the engraftment and habitat of seaweed spores, the engraftment and habitat of shellfish, the infestation and habitat of fish, and the formation of vortices By supplying nutrients and oxygen by means of the present invention, it is designed and manufactured in a complicated form to achieve various purposes such as providing a good habitat environment for fish and shellfish.

Also, it is a latent agent that absorbs the energy of waves to prevent wave attenuation or reflection wave generation. It is not designed as a structure that effectively provides the functions as (i) and as a breakwater, and it is not designed as a structure that prevents the waves from exceeding the breakwater and has artificial reef function. There was a structural problem in using the sofa block as a sleep and breakwater.

Recently, due to the rising sea level due to global warming or frequent typhoons, accidents are caused by the monthly waves, and efforts have been made to prevent them. Currently, the prevention of the monthly waves by simply raising the height of the breakwater is prevented. As a result, the construction cost of the breakwater was increased.
