Abstract

As an artificial reef for propagation of fishery resources, the present invention relates to prefabricated forced reefs that can be made by assembling horizontal and vertical members of a certain standard without welding by the sea and making the volume as large as possible from sea to deep sea.

The present invention is assembled from the structural structural steel (ss400) or seawater-resistant steel to the assembly, the assembly of the assembly 10 that can assemble the horizontal, vertical, height member 12 in six directions of the steel reefs to form a small block of cube The small blocks are assembled in the left, right, and height directions to form the shape of fish that fits the characteristics of algae or fish.

Iron plate (13,14) is attached to the bottom surface and side rim of the prefabricated steel reef so that it can be installed in nizil or sani, not rock. To increase the effect of attaching fishery resources.

Description

Multi-stage prefabricated forage with internal spaces {omitted}

Artificial reefs infuse concrete reefs, forced reefs and needle tip reefs in the sea to increase fishery resources. In Korea, more than 90% of them are put into concrete reefs, but concrete reefs are heavy due to their weight per unit volume. Can't be produced in small size. Artificial reefs have a larger picking effect as they are larger and larger, but concrete reefs cannot be added because they have a heavy weight and weak material strength.

In order to reduce the manufacturing cost and to reduce the weight per unit volume in the manufacture of artificial reefs, the present invention has an internal space where fish can play. By attaching it, it can be installed without falling into nizil or sanizil.

As shown in Figure 1, the fabrication of the prefabricated forced reef is connected to the assembly 10 in six directions (10a) by connecting the horizontal, vertical, and height member 12 of the same specification with a bolt, nut (11la) cube Unit small blocks (figure 1) are completed, and when the small blocks are assembled in succession, they can be manufactured in multiple stages or in large-scale reefs. The surface volume of the reef can be increased with less

FIG. 2 is a perspective view showing the inclination plate 20 at a 45 degree angle attached to the unit small block, and the inclination plate is inclined to cause a rising flow of the algae rising upward, so that the plankton or floating materials rise up by the rising flow. It is possible to adjust the shade and shadow effect in the sea by increasing the amount of installation depending on the fish species according to the region. In addition, the inclined plate 20 has a number of holes can generate fluid sound waves when the algae or the current flows to attract fish that detect the sound waves.

Figure 3 shows the installation appearance of the natural stone or oyster shell gabions built in the upper or the inside of the reef, the gap between the natural stone and oyster shell can give a good living environment to the fry.

4 (A) and 4 (B) are a perspective view and a cross-sectional view of a 5-step height offshore forced reef completed by the continuous assembly of the small blocks of FIG. 1, and a side iron plate 13 at the lower end of the assembled reef. And the bottom iron plate 14 is connected to the horizontal, height member 12 with bolts, nuts (13a, 14a) and attached to the four bottom edges of the first stage. This space can be installed without falling into nizil or sani, and if necessary, this space is filled with natural stones, so that the senjo flow does not fall or slip.

As shown in Figs. 4A and 4B, the inclined plate 20 is provided so that algae flows over the central portion of the reef.

As shown in Figure 4 (B) by placing a large space 41 in the inside of the forced reefs to increase the external volume to achieve the effect of the reefs, and to reduce the weight per unit volume to have an effect when installed in nizil. In addition, the ponchos filled with natural stone or oyster shell were attached to the fishery to enhance the protective effect of the fry.

As shown in the detailed view of FIG.

5 (A) and 5 (B) are a perspective view and a cross-sectional view of a forced reef that can be used for near sea and deep sea. The reef has eight stages, and the inside of the reef has two spaces 51a and 51b. There is a dog.

6 (A) and 6 (B) are a perspective view and a cross-sectional view of a forced reef that can be used for the deep sea. The reef is a 10-stage large reef and has six spaces 61 inside the reef.

In manufacturing prefabricated forced reefs by assembling steel, the internal space is placed inside the reefs to reduce the weight per unit volume and manufacturing cost, and the slant plate 20 is inclined at an angle of 45 degrees so that the flow of algae flows upward. It raises a float or plankton of the bottom and raises it and raises an effect.

The inclined plate 20 has a plurality of holes to generate a fluid sound wave by passing a part of the algae to increase the picking effect of the fish to detect the sound wave.

At the bottom of the reefs, iron plate (13,14) is attached to the bottom and side to make a closed space, so that the reefs do not fall deeply into the poor terrain of nizil and sanizil, It is possible to prevent slipping and falling, and the gap of this natural stone has a high protection effect. After 5 years or 10 years after the installation of the reef, the results of the post investigation show that some reefs are buried and the depth of the burial is about 1 meter. Therefore, it is manufactured from 10 meters to 20 meters of prefabricated forced reefs, so even if some bottom is buried, the effect of the bottom can be seen. Rather, if the bottom part is buried, the installation stability of the bottom is increased.
