The present invention relates to a fish habitat creation device for rivers, and more specifically, to a fish habitat that can provide an environment such as a shelter and a spawning area for a variety of fish such as carp or crucian carp at the bottom of a river at a minimum cost. It is to be able to easily composition.

In recent years, as the land use of rivers increases and urbanization progresses, the river environment changes significantly. Especially in urban rivers with high land use density around rivers, maintenance of reservoirs and reservoirs for flood control purposes is required. In addition, the river environment is changing due to the maintenance of sewer line and the construction of river banks. Moreover, as the water channel descends, the curved line of the natural river is transformed into a straight line, and the slope of the water channel is concrete and the surrounding environment is uniform. It is true.

On the other hand, in general, the river is installed in the revetment facility is made of concrete, the most of these revetment facilities are often installed as a concrete retaining wall.

However, in the case of installing the concrete retaining wall described above, it is not possible to provide a spawning place for the fish inhabiting the river, so that the unique natural environment of the river, such as the number and type of algae as well as the fish in the river, decreases rapidly. There are many problems such as the destruction of the underwater ecosystem, which is a purification function.

Therefore, the present invention has been devised to solve the above-mentioned problems, the environment-friendly fish habitat that can provide an environment, such as a shelter and spawning habitat for a variety of fish such as carp or crucian carp on the bottom of the river The aim of the present invention is to provide a stream fish habitat creation device that can be easily created at the cost of the fish and thus protects the river aquatic ecosystem.

In order to achieve the above object, the present invention is a river characterized in that the first and second fish habitats are formed in the bottom and bottom and the left and right directions to form a lattice shape in the bottom of the river and the fishery block composed of artificial water plants A fish habitat establishment is provided.

In addition, the eoeo blocks are disposed in each corner portion and is formed in a hollow ball shape to the first fish habitat for large fish inhabiting, the center of each of the first fish habitats and the small fish to inhabit The second fish habitat is formed in a smaller size than the first fish habitat and has a hollow ball shape, and is characterized by consisting of artificial plants that are connected to each other by a support rod in the center of the inner peripheral surface of the second fish habitat.

In addition, a through hole is formed in the center of each of the first and second fish habitats, characterized in that a plurality of fish movement holes are formed at regular intervals on the outer peripheral surface of the first fish habitat.

And, both sides of the second fish habitat is characterized in that the support rods are inserted into and fixed to the fish moving hole of the first fish habitat to support the second fish habitat integrally formed.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object will be described in detail.

1 is a longitudinal cross-sectional view showing a state in which the Associate block is installed on the bottom surface of the river according to the present invention, Figure 2 is a perspective view showing the Associate block according to the present invention, Figure 3 is a cross-sectional view showing an Associate block according to the present invention, Figure 4 is a longitudinal cross-sectional view showing the main portion of the Associate block according to the present invention.

The present invention is a concrete retaining wall 20 is installed on both sides of the stream 10 flowing water, the bottom surface of the river 10, the first and second lattice shape is repeatedly formed in the vertical and horizontal directions to inhabit the fish A fishery block 30 composed of a fish habitat 40, 50 and an artificial herb 70 is provided.

That is, the fishery block 30 is formed in a hollow ball shape at each corner portion, so that the first fish habitat 40 for inhabiting large fish is disposed, and in the center of each of the first fish habitat 40 A through hole 42 is formed, and a plurality of fish movement holes 44 are formed on the outer circumferential surface of the first fish habitat 40 at regular intervals.

In addition, a second fish habitat 50 is formed in a smaller size than the first fish habitat 40 and has a hollow ball shape in the center between the first fish habitat 40 so as to inhabit small fish. The through-hole 52 is formed in the center of the second fish habitat 50, and inserted into the fish movement hole 44 of the first fish habitat 40 on both sides of the second fish habitat 50, respectively. It is fixed and the support rod 60 for supporting the second fish habitat 50 is integrally formed.

And, the center of the inner circumferential surface of the second fish habitat 50 is connected by a support rod 62, respectively, so that the artificial aquatic plant 70 is installed.

1 to 4, the present invention configured as described above, as shown in Figures 1 to 4, the first and second fish habitat 40 is formed in a lattice shape is repeated in the vertical and horizontal directions to inhabit the bottom surface of the river (10) Since the fishery block 30 composed of the 50 and the artificial herb 70 is installed, the through-holes 42 and 52 of the first and second fish habitats 40 and 50, while the fish are less affected by the flow rate, Through the fish moving hole 44, the first and second fish habitats 40 and 50 can provide a comfortable habitat environment such as refuges and spawning places of fish, thereby effectively protecting the underwater ecosystem of the river.

In addition, since the Associate block 30 according to the present invention is an assembly type, even when the construction work on the river 10, the construction is very easy to take less construction time, thereby minimizing the construction cost of the Associate block 30 You can do it.

As described above, the present invention facilitates, at a minimum cost, a fish block, which is an environmentally friendly fish habitat that can provide an environment such as a refuge and spawning area for a variety of fish such as carp or crucian carp on the bottom of a river. In addition, it is possible to protect the underwater ecosystem of the river, and the construction work of the Associate block is easy to prefabricated and minimizes the construction cost, which is a very useful design that greatly improves the efficiency and reliability of the device.
