Description

Dolharbang Artificial Reef {Artificial reef having dolharbang shape}

The present invention relates to an artificial reef, more specifically, an artificial fish that is not lost by algae and other external forces, and is eco-friendly and has a porous surface, so that the implantation of aquatic plants and animals is easy, and an artificial fish is configured to have a beautiful appearance by having a dolharbang shape. It's about seconds.

China's fisheries is an important food and life industry that complements the limitations on land, and contributes greatly to the national economic development. Korea's aquatic products, including marine fishery and aquaculture, are about 3 million tons per year, which is an advanced fishery country.

However, the offshore fishery is reduced due to the declaration of exclusive economic zones in Japan and China, the expansion of large-scale landfilling and reclamation projects, the deterioration of coastal fishing grounds due to urbanization and industrialization, and the increase in water temperature due to global warming. Resources are also changing every moment. In addition, in the 1990s, the renovation of the new international maritime order following the launch of the WTO system and the entry into force of the UN Convention on the Law of the Seas led to the reduction of ocean fisheries, the reduction of resources in coastal fisheries, and the conclusion of fisheries agreements with neighboring countries. The focus was on resource creation, environmental conservation, fisheries restructuring, resource management fishery development, and development of aquaculture technology for high-income varieties. In order to prevent such fisheries from lowering productivity and to raise incomes of fishers and to build a foundation for fishing villages, in 1985, the coastal fisheries ranching plan was established to convert coastal fisheries from the conventional production center to the management center. Fisheries seedling discharge business is carried out.

Fishing reef (魚 礁) refers to a natural reef where many fish live as ridges of the seabed, such as rocks or rocks protruding from the bottom of the seabed, and plays a role as a land tree or forest in the sea. It provides the environment for fish and shellfish to live by altering the flow of seawater, providing food, and providing a hideout for fish.

These reefs are called reefs, sediments, and shrubs depending on their shape, area, and bottom quality. Upstream and downward flows occur along the terrain and the nutrients are transported to the upper layer where the sunlight is shining. Because of this, the breeding of plankton is vigorous, and the fry that feed on it gather, and the large fish that feed on these fry feed together to form a good fishery. The fish catch is considered to be a good fishery element because its complicated structure is suitable for fish to protect the body from the outside and vortexes are formed around the fish catches. The reefs are classified into volcanic reefs, structural reefs and coral reefs depending on the adults.

Artificial structures of concrete and iron are installed in the sea to function as natural reeds, which is called artificial fish reef. If artificial fishes are added, fish catches will be increased, and catches due to planned fisheries will be increased. Efficiency of fisheries and safe operation can be improved by reducing fishery operation cost through development of fishery near the fishery. You can expect. In addition, when an artificial fish is installed on the seabed in the coastal area, overfishing of the fishing boat is prevented.

Artificial reefs should be created with caution because they should not harm marine ecosystems. Materials used for artificial reefs are various, such as natural stone, steel, concrete, wood, tires, plastics, etc. Among them, concrete or steel has been used the most. The general shape of the artificial reef is provided with a hollow rectangular or hexahedral body, but the main body is composed of a skeleton only in the outer border to form a cylindrical, square or hexahedral shape with a through-hole formed on the wall of the body.

Concrete artificial reefs using cement are produced by mixing aggregate, sand, etc., and then demolding them in the formwork, so the outer surface itself is smooth, so that the concept of aquatic plants is not easy to grow. There was a problem that occurred. In addition, artificial reefs that are connected to form a plurality of steel structure, there is a disadvantage that the risk of loss due to damage and fall when the algae or other external force is applied. In particular, there is a problem that the installation position can be easily changed by the blue at the low depth point.

In addition, the conventional artificial reefs are simply produced for the purpose of implantation and growth of aquatic plants and animals generally have a simple shape. Accordingly, when the artificial reef is installed in the area where underwater leisure such as snorkeling is performed, there is a disadvantage that the pleasure of underwater leisure is halved.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of Dolharbang artificial reefs according to the present invention.

1 is a perspective view of the Dolharbang artificial reefs according to the present invention, Figure 2 is a perspective view of the support block included in the present invention, Figures 3 and 4 is a front view and a side view of the Dolharbang artificial reefs according to the present invention.

Dolharbang artificial reefs according to the present invention, as a structure for creating a growth environment of fish and shellfish by providing a habitat space, spawning space and fry growth space of the fishery resources, the upper block (100) having a face shape on the front and rear The connection block 200 is connected to the lower side of the upper block 100, and is coupled to the bottom of the connection block 200 to support the connection block 200, but the upper block 100 or the connection block 200 It is configured to include a support block 300 is made wide to have a horizontal cross-sectional area larger than). At this time, the artificial stone reef Dolharbang according to the present invention has a structure in which the center of gravity is located so that it does not fall easily, that is, the connection block 200 has a larger horizontal cross-sectional area than the upper block 100, the support block 300 is It is preferable that the horizontal cross-sectional area is larger than that of the connection block 200.

On the other hand, the connection block 200 is provided with a through-hole so that water can pass through the inner side when the water flow caused by algae or blue. When the through-hole is formed in the connection block 200 as described above, when seawater pressure is applied to the side of the Dolharbang artificial reef according to the present invention by the horizontal seawater flow will pass through the through-hole, Dolharbang has the advantage that can be prevented from falling or moving by the flow of sea water.

At this time, the dolharbang artificial reefs according to the present invention do not fall to the seawater flow in the left and right direction, and do not fall in the forward and backward seawater flow, the through hole is the left and right through-hole 210 through which the water flowing in the left and right direction and the water flowing in the front and rear direction It is preferable that the front and rear through-holes 220 passing therethrough are manufactured. In this embodiment, only two cases, that is, the right and left through holes 210 and the front and rear through holes 220 which are arranged at right angles to the connection block 200 are shown, but the tidal current at the point where the artificial reef is installed The direction and number of through holes formed in the connection block 200 may be variously changed according to various conditions such as the characteristics of the blue wave and the intensity of the water current.

On the other hand, the bottom of the sea floor on which the artificial reef is installed is not flat and bumpy, if the bottom of the support block 300 is formed in one plane, that is, the support block 300 is made in a rectangular parallelepiped, the artificial fish according to the present invention A problem may occur that the candle may not be stably settled and may be easily shaken by algae or blue. In particular, many kinds of fish and shellfish are gathered in artificial reefs, and as mentioned above, when artificial reefs are not reliably settled on the seabed and easily shaken, artificial reefs are inverted or rolled when marine organisms such as fish collide. The disadvantage is that the concern becomes very large.

The support block 300 included in the artificial reef according to the present invention is formed in a square plate shape so as to reduce the above-mentioned fear of loss and the support plate 310 is connected to the center portion of the upper connection block 200 and In addition, the bottom of the support plate 310 is characterized in that it consists of a support leg 320 extending downward from each corner. When the support block 300 is formed of the support plate 310 and the support leg 320 as described above, only the support leg 320 having a relatively narrow horizontal cross-sectional area is seated on the seabed surface of which the surface is uneven, and the support plate 310 is wide. ) Is spaced upward from the sea floor, so that it can remain stable without being shaken by external forces. In addition, when the support plate 310 is installed so as to be spaced apart from the bottom, the space between the bottom and the bottom of the support plate 310 may be utilized as a habitat space or spawning space and the fry growth space of the fish and shellfish, A very large effect on the growth environment can be obtained.

In addition, the artificial reefs according to the present invention have a structure similar to a sculpture carved into a meaningful shape such as a face, rather than a geometric shape, so that it is installed on a shallow sea surface and is noticeable to tourists enjoying underwater leisure. There is an advantage that can give an aesthetic when done. In particular, if you want to install the artificial reef in accordance with the present invention in the sea near Jeju Island, as shown in this embodiment by forming a face shape of the stone block in the upper block 100, it can be promoted to one tourism target Will be.

At this time, the shape formed in the upper block 100, various patterns in addition to the Dolharbang face shown in this embodiment may be added. That is, the shape formed in the upper block 100 may be replaced with any shape if it can give an aesthetic sense to tourists enjoying underwater leisure.

On the other hand, the four support legs 320 extending downward from each corner of the support plate 310 is radially opened so as not to fall easily when a lateral external force is applied to the upper block 100 or the connection block 200. That is, it is preferable that the structure is manufactured to be inclined to extend in a direction away from the vertical central axis of the support plate 310 toward the lower end. When the four support legs 320 are inclined to extend outwardly as described above, the distance between the ends of the support legs 320 becomes farther and the center of gravity of the artificial reefs is lowered, so that the artificial reefs fall down due to lateral external force. This has the advantage that it is more reliably prevented. In this case, as the support leg 320 is located far from the center of the support plate 310, the phenomenon of falling down the artificial reef can be prevented, and the support leg 320 has a support plate (as shown in the present embodiment). It is preferable that each of the four corners of the bottom of the 310 is provided.

When the inclination of the support leg 320 is excessively gentle, the fall of the artificial reef can be more reliably prevented, but the spacing between the sea bottom and the support plate 310 is narrowed, so as not only to reduce the efficiency of the shellfish growth environment composition, When the lower external force is applied to the upper block 100 and the connection block 200, the support leg 320 may be broken. Therefore, it is preferable that the inclination of the support leg 320 is appropriately set according to the overall size, size, use, etc. of the artificial reef.

In addition, the narrower the area that the support leg 320 is seated on the sea floor, but the artificial reef can be stably fixed, but if the support leg 320 is made thin, the upper block 100 and the connection block 200 The problem arises that it cannot be stably supported. Therefore, the support leg 320, as shown in the present embodiment, the side connected to the support plate 310 is thick, the lower end portion is preferably made relatively thin.

Artificial reefs according to the present invention may be made of a general reinforced concrete structure, or may be made of a material in which ocher or synthetic resin is mixed with concrete. At this time, in order to improve the attachment effect of the aquatic organisms and the composition efficiency of the benthic creatures accordingly, it is preferable that a plurality of grooves are formed on the surface of the upper block 100, the connection block 200, the support block 300. The upper block 100, the connection block 200, and the support block 300 may be manufactured so that irregularities are formed on the surface by mixing two or more materials, or the grooves are formed on the surface through a separate processing operation. In addition, it may be made of basalt so that a plurality of grooves are provided on the surface without additional processing.

As mentioned above, artificial reefs according to the present invention can be made of any material if a plurality of grooves can be formed on the surface, it will be most preferable to be made of basalt in consideration of environmentally friendly aspects.

5 is a cross-sectional view of the Dolharbang artificial reefs according to the present invention cut along the line A-A shown in Figure 3, Figure 6 is a bottom view of the Dolharbang artificial reefs according to the present invention.

In order to make the growth environment of fish and shellfish more effective, an empty space that can be utilized as a habitat, spawning space and fry growth space of fish and shellfish should be secured inside the artificial reef. There is a risk of falling easily by, and increasing the total size of the artificial reefs not only increases the manufacturing cost of artificial reefs, but also has the disadvantage that it is difficult to transport the artificial reefs to the sea and to drop to the sea floor.

Therefore, the artificial reef according to the present invention is plate through hole 330 is formed in the center portion of the support plate 310, so as to secure a larger internal space in a limited standard, the left and right through holes of the connection block 200 210 and the front and rear through holes 220 are preferably formed to communicate with the plate through hole 330. When the plate through-hole 330 is formed in the support plate 310 as described above, the space for spawning or spawning and cheering space of the fish and shellfish is secured more, and the lower space of the support plate 310 is left and right through-hole 210. ) And the front and rear through-holes 220, there is an advantage that the growth environment of the fish and shellfish is significantly increased because the space for hiding the fry more.

In addition, if the left and right through holes 210 and the front and rear through holes 220 are configured to communicate with the lower space of the support plate 310, even if the algae toward the artificial reef is formed in an obliquely inclined direction, the left and right through holes 210 ) And the flow of water introduced into the front and rear through holes 220 is introduced into the lower side of the support plate 310 and exits between the support legs 320, so that a large external force is not transmitted to the artificial reef, and thus the present invention. There is an advantage that the artificial reef can be kept more stable by the state.

Meanwhile, an inlet groove connected to a central portion of the upper block 100 from a point corresponding to the plate through hole 330 of the bottom surface of the connection block 200 so that an empty space inside the artificial reef can be more secured. It is preferred that 110) be further formed. When the inlet groove 110 is formed to the inside of the upper block 100 as described above, since the space inside the artificial reefs according to the present invention has a wider and more complicated structure, it becomes easier to inhabit or spawn fish and grow fry. There is an advantage. In particular, small-sized fish and shellfish can hide the body in the inlet groove 110 to avoid attacks from other aquatic organisms, there is an advantage that the growth of fish and shellfish can be made more active.

The shape of the inlet groove 110 is not limited to the wedge shape that narrows toward the upper side as shown in this embodiment, it can be replaced by various shapes in accordance with the growth characteristics of fish and shellfish.

While the present invention has been described in detail with reference to the preferred embodiments thereof, the scope of the present invention is not limited to the specific embodiments but should be construed in accordance with the appended claims. Those skilled in the art will appreciate that many modifications and variations are possible without departing from the scope of the present invention.
