The present invention relates to an artificial reef combined tetrapod that can provide resting spaces and spawning places for various fish and shells, and more particularly, includes an opening and a lower space generating member in the body to offset algae resistance and hides of fish and shellfish. In addition to providing a combination of artificial reefs and tetrapods at the same time can be used to provide the convenience of use, thereby greatly improving the quality and reliability of the product.

As is well known, tetrapod is a concrete structure that functions to disperse waves by stacking in and out of the breakwater. It is a triangular block with four horns made of concrete and is installed in the part affected by the wave on the breakwater. It is an artificial concrete structure to protect the elements stone blocks and blocks. In addition, the block has a low center position and good safety, so that the weight can be lighter than that of concrete, and the block can be interlocked with each other and can be installed on the slope of a steep slope, so that an economic cross section can be obtained.

In addition, artificial reefs can be called fishing facilities aimed at attracting, protecting, and cultivating marine animals by artificially installing structures on the seabed or in the sea. Reefs are usually installed in waters of 10-50 m depth. Fish have an instinct to protect themselves while staying close to or in contact with other objects in the ocean. Artificial reefs are therefore adapted to this instinct of fish. And artificial reefs slow the flow of water and slow the speed of water, which not only causes the fish to gather but also serves as a spawning ground.

Where the artificial reef is installed, the fish density is three to four times higher than the natural fishery. Also, fish species such as rock dome and rockfish are used as hide places for artificial reefs when they are chased by large fish. Artificial reefs should be created with caution because they should not harm marine ecosystems. It is usually made of concrete or stone, and its shape is rectangular, hexagonal, cylindrical and hemispherical.

However, the above-described conventional artificial reefs and tetrapods have the following problems.

That is, the artificial reefs can not play the role of breakwater, and as shown in Figure 1, tetrapod (T) has a problem that can not serve as a hiding place for various fish, shellfish and fish.

In addition, since the prior art tetrapod is placed in contact with the floor without a gap with the ground, there is a problem that can not serve as a hiding place for fish and shellfish.

In addition, there is also a problem that can not be used as a habitat for the fish because there is no opening that can be inhabited as the fish pass through.

The present invention has been made to solve the above problems of the prior art, and the first object of the present invention is to provide a tetrapod combined artificial reef to provide a resting place and spawning place for various fish and shellfish, The second purpose of the present invention is to provide an opening and a lower space generating member in the body so as to provide algae resistance cancellation and a hideout of fish and shellfish, and the third purpose is to use the artificial reef and the tetrapod at the same time. In order to provide convenience of use, the fourth object of the present invention is to provide a tetrapod combined with artificial reefs, which can greatly improve the quality and reliability of the product.

In order to achieve the above object, the present invention provides a tetrapod, which is a concrete structure having a function of dispersing waves by stacking in and out of the breakwater, the body having an opening so as to communicate with each other in four directions at the center; Legs extending in all directions of the body and formed with bent portions to easily inhabit fish and shellfish in the longitudinal direction; And a protruding portion at the end of the leg, the lower space generating member having the body spaced apart from the ground to serve as a habitat and hiding place for fish and shellfish, and at the end of the bent portion to serve as a hideout for fish and shellfish. It is characterized in that the shade is further provided.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention for achieving this purpose are as follows.

The artificial reef combined tetrapod applied to the present invention is configured as shown in Figs.

In the following description of the present invention, if it is determined that specific descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The following terms are terms set in consideration of functions in the present invention, which may vary depending on the intention or custom of the producer, and their definitions should be made based on the contents throughout the specification.

The present invention provides an artificial reef combined tetrapod to provide a resting space and a spawning place for various fish and shellfish, in particular, the body 10 is provided with an opening 12 and the lower space generating member 13, the algae resistance It was designed to provide an offset and a hideout for fish and shellfish, and to provide convenience for use by using both artificial reef and tetrapod at the same time.

Specific technical configuration of the present invention for this purpose is as follows.

That is, in the tetrapod, which is a concrete structure that functions to disperse waves by stacking the inner and outer ports of the breakwater, protrudes at the end of each leg 11 extending in all directions of the tetrapod body 10, and the body 10 extends from the ground. The lower space producing member 13 is provided to be spaced apart to serve as a habitat and a hiding place for fish and shellfish.
