Description

Artificial reef and artificial reef complex

The present invention relates to artificial reefs and artificial reef complexes, and more particularly relates to artificial reefs and artificial reef complexes to increase the stability to external forces and simple manufacturing.

In general, the reefs, which are a form of fishing grounds with favorable conditions for fish gathering, occur frequently in the raised parts of the seabed where fishes gather, and depending on the shape, width, depth, geology, reef, retreat, and state, etc. In the vicinity of these reefs, upflows and downflows occur along the terrain, the circulation of seawater becomes active, and plankton grows in a large quantity, and the food chain of the ecosystem is naturally formed, forming a good fishing ground.

However, in recent times, natural reefs are gradually increasing due to environmental changes due to water temperature rise due to environmental pollution and photosynthesis inhibition of algae, and many of the reefs are gradually disappearing. The reduction of these reefs leads to the reduction of fish that use them to feed and hide.

Therefore, in order to prevent the decline of fish reefs, the group of artificial reefs has recently been formed on the coastal seabed to enable the aquatic plants such as algae to grow and protect naturally or artificially within a short time, and thus provide a habitat for fishes to increase fishes. To promote.

Artificial reefs create an environment where algae can attach to and propagate, allowing fish to live there or become spawning grounds.

It also allows abalone, conch, and other aquatic animals that feed on the seabirds to eat the seaweed. In addition, fisheries resources, which are the target of coastal fishing, can be overfished, and artificial reefs can be an obstacle when dragging the nets, thereby protecting the young from fishing nets with high fishing efficiency.

Generally used artificial reefs are hexahedral in overall shape, the through-holes are formed in the artificial reefs through the outer surface and the inner surface, allowing the current flow through the through-hole formed in the square cylinder and formed in the square barrel It will provide an environment for the fish to grow in the inner space and provide the hides and food for the fish.

However, a square barrel or cuboid-shaped artificial reef having such a hole has a disadvantage in that stability due to the blue color is significantly lower because the size of the fish reef and the weight are smaller than the size of the reef.

In addition, because the hexahedral artificial reefs have a certain shape, they are not only stacked in a staggered manner, but also because they have no interlocking parts when stacked, they have low stability due to blue and algae in the ocean. The entire bottom of the artificial reef can sink.

Therefore, it is possible to have a space volume without forming a through hole, to increase stability against external force, to minimize sinking even when laminated on soft ground, to be effective for the habitat of attached organisms, to be effective in generating vortices and turbulent flows, and It is necessary.

The present inventors have made efforts to solve the above-mentioned disadvantages and problems of the prior art as a result of having a plurality of the body to have a space volume even without forming a through-hole through the main body, it is not installed through the weight of the weight compared to the size The present invention has been completed by developing artificial reefs and artificial reef composites, which not only solve the disadvantages of light weight, but also have a simple manufacturing effect, thereby reducing manufacturing costs.

The artificial reef 100 according to the embodiment of the present invention includes a main body 110 and a plurality of grooves 117 formed in the main body 110.

The main body 110 consists of a central portion 111a and four protrusions 111b protruding from the central portion 111a, and has a vertical cross section X-shaped with respect to the bottom surface to be installed.

That is, the main body 100 is composed of both sides, that is, the outer circumferential surface 115 connecting the one side X-shaped side surface 111 and the other side X-shaped side surface 113 and both side surfaces 111 and 113, and the plurality of grooves 117 are It is formed on the outer circumferential surface 117, and is formed to connect both side surfaces 111 and 113 of the main body 110.

That is, the main body 110 of the artificial reef 100 has a shape in which a pillar having an X-shaped cross section is laid so that the X-shaped cross sections are both sides 111 and 113.

Both sides 111 and 113 of the main body 110 may be divided into four protrusions 111b having an X shape and a central portion 111a of the center of the four protrusions 111b, and each protrusion 111b may be disposed inwardly. Three recessed grooves 117 are formed at one corner and one at each end. That is, a total of 28 grooves 117 are formed on both side surfaces 111 and 113, respectively, to form irregularities.

Specifically, referring to the one side X-shaped side 111 of the main body 110 with reference to Figure 1, the length (a) between the spaced apart a predetermined distance from each end in both ends of the protrusions (111b) facing each other is 2200mm Preferably, this is the sum of the lengths b and b 'of each protrusion 111b plus 800 mm and the length e 600 mm of the central portion 111a.

The length of the central portion 111a is obtained by adding 400 mm of the length d of the relatively narrow portion to the end of the protrusion 111b and 100 mm of the lengths c and c 'of the protrusion 111b contacting the central portion 111a. to be. That is, each protrusion 111b has a shape in which the width thereof becomes narrower toward the end.

In addition, the length f between two neighboring protrusions 111b is preferably 1840 mm.

Looking at the longer side of the protrusions 111b, the size of the grooves 117 formed in each of the protrusions 111b is 100 mm each of the lengths of the grooves 117 into the protrusions 111b. 150 mm each, and the lengths of the side portions of the first and third grooves 117 are 100 mm, respectively, so that the sum of all of them becomes the length of one protrusion 111b.

Looking at the short side of the protrusion 111b, one groove 117 formed at the end also has a length of 100mm, the length of both ends is 150mm, respectively, so that the length is 400mm.

Also, as shown in FIG. 2, the distance between the two side surfaces 111 and 113 is preferably 3000 mm.

The body 110 according to an embodiment of the present invention preferably has the size described above, but this value is not limited thereto and may be changed according to the state of the sea area where the artificial reef 100 is installed. In addition, the number of grooves formed on the outer circumferential surface 115 is not limited thereto.

The groove 117 formed on the outer circumferential surface 115 of the main body 110 according to the embodiment of the present invention increases the surface area of the main body 110 so that more marine life can be attached and inhabited.

The artificial reef 100 according to the embodiment of the present invention is manufactured by using a formwork having a shape corresponding to the main body 110 in which the groove 117 is formed. And cost can be reduced.

Specifically, the conventional hexahedron-shaped artificial reefs are complicated to manufacture, while the cost of manufacturing is at least about 1 million won, while the artificial reefs 100 according to the embodiment of the present invention have no internal through-holes, so the manufacturing cost is greatly reduced. Because it can be made, the production cost of 70 ~ 800,000 won per piece can be manufactured very economically.

Concrete mortar can be added to the formwork, and reinforcement can be optionally built inside. After curing the concrete mortar after curing sufficiently to remove the formwork is completed the manufacture of artificial reef (100).

In this case, the concrete may use general concrete and may be used in combination with porous concrete. Porous concrete is a lightweight concrete with a lot of small holes in the concrete and is manufactured to allow water to pass freely. When the artificial reef 100 is manufactured, seawater flows through the main body 110 to enable the interior of the main body 110. It is possible to inhabit the plankton and microorganisms that feed marine life, thus maximizing the effectiveness of the reefs.

Artificial reef (100) according to an embodiment of the present invention can be classified according to the type of living organisms in accordance with each part of the body (110).

For example, the upper outer circumferential surface of the main body 110, that is, the upper surface of the protrusion 111b formed on the upper portion of the protrusion 111b that does not contact the bottom surface 400 may receive sunlight, and thus may be inhabited by algae capable of photosynthesis. And, the lower surface of the protrusion (111b) in contact with the bottom surface 400 is blocked by sunlight can be inhabited by marine life unnecessary photosynthesis.

Shells such as abalone and seashell, which are mainly attached and inhabited, are suitable on the outer peripheral surface of the middle part of the main body 110.

In addition, the upper outer circumferential surface of the main body 110, that is, the upper surface of the protrusion 111b formed on the upper surface that is not in contact with the bottom surface 400 forms a slope because the cross section is V-shaped, but may receive sunlight all day long. For example, when the left side of the upper surface of the protrusion 111b receives sunlight in the morning, since the right side may receive sunlight in the afternoon, it is not flat but may receive sunlight all day, thereby maximizing time for photosynthesis. .

In general, if artificial reefs on the direct wall are installed in the sea area, wake areas occur when the birds strike the reefs. However, in the artificial reef 100 according to the embodiment of the present invention, the vertical cross section is X-shaped, and the outer circumferential surface 115 protrudes between the protrusions 111b based on the central portion 111a, not the straight wall, and is recessed between the protrusions 111b. Since there is a recessed portion, when the current strikes the outer circumferential surface 115 of the main body 110, there is an effect of easily generating vortices and melt flows.

3 is a view illustrating a state in which a working line is wound around the main body of FIG. 2.

Referring to Figure 3, the outer circumferential surface of the main body 110 is wound around the groove 117, the engagement line 200 for seaweed spore transplantation. 3 illustrates an example in which only one engagement line 200 is wound, but a plurality of engagement lines 200 may be wound.

Since the groove 117 is formed in the protrusion 111b, it is easier to wind the engagement line 200. Thus, the algae can be implanted by winding the engagement line 200 in the groove 117 formed in the protrusion 111b or the protrusion 111b, so that it can be used not only to provide a habitat for marine life, but also as an artificial reef for forming a seaweed ground. Do.

The conventional hexahedron-shaped artificial reefs have no grooves for winding the working wires, but the working reefs are put on the artificial reefs using a fixing means such as nails, but the artificial reefs 100 according to the embodiment of the present invention It is more economical because the method of winding the working line 200 is very simple because it only needs to be wound tightly in the groove 117 so that the working line 200 does not turn out.

Artificial reef (100) according to an embodiment of the present invention is generally preferably a plurality of facilities to form the artificial reef composite (300). An example of the artificial reef complex 300 will be described with reference to FIGS. 4 and 5.

4 to 6 is a view showing the artificial reef complex according to an embodiment of the present invention.

As shown in FIGS. 4 and 5, at least two artificial reefs 100 may be installed, and a plurality of artificial reefs 100 may be placed on the bottom surface 400 of the sea area and stacked on top of each other.

The artificial reef 100 according to the embodiment of the present invention may be installed in a sea area having a minimum depth of about 7 m. However, when the facility is installed in a sea area of such a depth, the stability of the artificial reefs due to the blue waves is remarkably decreased. The artificial reef (100) is X-shaped and not only through-holes are formed, but also when the facility is equipped with a number of X-shaped interlocking, high stability due to blue or algae, so the facility is possible in low waters.

In a low sea area, the artificial reef 100 may be installed as a single layer, and in a deep sea area, the artificial reef complex 300 may be stacked in multiple layers so that the total height of the artificial reef complex 300 is suitable for the depth of the sea area.

In addition, when the bottom surface 400 of the sea area is made of sand or the like, if the artificial reef 100 is laminated in multiple layers, the bottom artificial reef 100 is moved to the bottom surface 400 by the weight of the artificial reef composite 300. Since it may sit, the height of the stack may be changed in consideration of the state of the bottom surface 400 and the depth of the sea area.

When installing a plurality of artificial reefs 110, it is preferable that the facilities are staggered with each other. Specifically, the space volume 120 between the artificial reefs 100 by installing the protrusions 111b of the other artificial reefs 100 to be inserted into the concave portion formed between the two protrusions 111b of the artificial reefs 100. Can be used to provide space for fish to inhabit.

That is, the three-dimensional artificial reef composite 300 can be configured by adjusting the number of layers stacking the artificial reefs 100 and the number of staggered facilities according to the depth of the sea area and the state of the bottom surface 400. In this case, marine organisms may be inhabited by being divided into the upper part, the middle part, and the lower part of the bottom man-made artificial reef 100.

Conventional hexahedron-shaped artificial reefs can not be crossed when the layer is laminated construction, the artificial reefs 100 of the present invention because the X-shaped projections formed of a concave portion between the protrusion 111b and the protrusion 111b projecting portion (111b) ) And the concave part can be crossed and installed.

Therefore, the artificial reef 100 of the present invention can improve the stability against the current, even if one of the stacked artificial reefs (100) fall to the ground can be maintained constant in the shape installed on the ground.

In addition, since the surface area of the artificial reef 100 of the present invention is increased due to the protrusion 111b and the concave portion, the ground pressure on the bottom surface 400 is increased. Because of the weight, the bottom of the artificial reef (100) sinks much less than conventional hexahedral artificial reefs.

In general, in the case of a conventional hexahedron-shaped artificial reefs are stacked in one case the entire artificial reefs are often subsided, but in the artificial reef composite 300 of the present invention even when stacked in multiple layers as shown in Figure 6 There is an effect that only the protrusion 111b directed toward the bottom surface 400 of the artificial reef 100 of the layer sinks.

As a result, the present invention develops an artificial fish that includes a main body consisting of an outer circumferential surface connecting both sides and both sides having an X-shaped vertical cross section, and an artificial reef including a plurality of grooves formed to connect both side surfaces of the main body to the outer circumferential surface, and having a plurality of artificial reefs. By developing a super complex, it is possible to increase the stability to external force, to secure a space volume, to be effective in the habitat of attached organisms, to be suitable for the living organisms of various organisms, and to effectively generate vortices and dissolved flows.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various changes and modifications will be possible.
