The function as a fish reef for seawater communication and evacuation or habitation of aquatic animals or seaweeds can be realized through the sheltered habitat formed by the distribution hole, etc. It relates to a sofa block that enables stable installation.

In general, breakwaters are built to reduce damage from waves in areas that are in contact with the sea, such as piers, harbors, shorelines, and coastal roads.

In particular, in the vicinity of the breakwater, the sofa blocks for preventing the waves from directly hitting the breakwater are regularly or irregularly arranged according to their shape.

That is, depending on the topographical conditions in which the breakwater is constructed, there are cases where the sofa blocks are constructed by regular arrangement, while there are cases where they are constructed by stacking sofa blocks of a specific shape from the bottom of the sea.

As the most common sofa block in the prior art, it is often called a tetrapod, and a truncated cone protruding outward in four directions is used.

As these tetrapods are in a state of mutual entanglement with neighboring tetrapods by a truncated cone protruding in four directions, the construction state can be maintained for external forces below a certain level.

On the other hand, in the form of a sofa block installed around a breakwater by a regular arrangement, 'breakwater using assembly block' in Korean Patent Publication No. 10-2004-0090619, 'for sofa disaster prevention' in Korean Patent Publication No. 10-0583595 Block', 'Coastal Port Protection Block' in Korean Patent Publication No. 10-0642342, 'Prefabricated sofa block used in breakwater' in Korean Patent Publication No. 10-650480, 'Breakwater slope' in Korean Patent Office Registration No. 10-0720312 There is a prefabricated sofa block for clothing.

As described above, the conventional sofa blocks are arranged and masonry in a vertical or inclined form on one side wall of the breakwater constructed by pouring concrete, etc., and are fixed to the breakwater.

However, some of the above-mentioned conventional sofa blocks have problems such as not being able to fully demonstrate the sofa function to prevent safety accidents by lowering the energy of waves coming from the open sea.

In addition, some of the above-mentioned conventional sofa blocks have problems such as difficult and high installation costs or difficult to install quickly and stably as they have a structure that requires a separate fixing means when installed on the side of the breakwater.

In addition, some of the above-mentioned conventional sofa blocks have a problem in that it is difficult to function as a stable fish reef in the habitat of fish or algae, although the function of lowering the wave energy is exhibited to some extent.

Therefore, it is possible to offset the waves coming in from the open sea to prevent safety accidents around the breakwater, and to implement the function as a fish reef for seawater communication to the inner harbor and evacuation or habitation of aquatic animals or seaweeds through the sheltered habitat space. As a fixing means for separate blocks is not required, research and development of a sofa block that can be quickly and stably installed through a simple masonry method is required.
