Description

Tripod type seaweed forest {Artificial reef for seaweed forest with tripod type}

The present invention is to install a connecting plate protruding algae attachment plate along the support legs for settlement resistance installed in the form of a tripod, while the spacing between the algae attachment plate to form a concealed space of shellfish and fry, various Ensuring that the surface provides sufficient surface structure for the natural survival of the algae, while simplifying the structure of the reef itself, the passages and spaces necessary for the feeding and hiding activities of shellfish and fry are based on the algae. Tripod-type marine forests that can be connected efficiently and organically and contribute to the improvement of convenience according to the facilities of the reefs and to prevent the fall and fall of the reefs, as well as to reduce the logistics cost by the stacked transportation of the reefs. It is about.

In recent years, the coastal waters of Korea have gradually disappeared various seaweeds inhabiting the seabed or seabed due to various complex environmental factors such as excessive inflow of various nutrients and abnormal high temperature phenomena. As non-calcite algae, which are the main culprit of whitening, grow rapidly, coastal waters are gradually being devastated.

The bleaching in coastal waters began in 1996, and in 2004, about 34% (4,540 ha) of Jeju coastal water and 14% (2,413 ha) of east coast waters. It is expected that the whitening of coastal waters will continue to increase.

When various seaweeds disappear due to the bleaching phenomenon as described above, shellfish and invertebrates such as abalone, hermit or sea urchin, which serve as a prey and hide, are also disappeared, as well as the spawning grounds and habitats of the fish by the seaweeds are destroyed. There is a serious problem that the rapid reduction of useful fish stocks that can be caught in the sea area.

Therefore, in recent years, artificial reefs have been installed in coastal waters, especially in shallow waters where the water depth is about 20m, so that seaweed forests can be formed by algae, which is necessary for the growth of various shellfish and fry. Efforts have been actively made to provide breeding grounds for shelter, hides and fish. In view of these conditions, various types of marine reefs have been developed and installed.

However, the marine reefs that have been developed so far do not deviate much from the frameworks of the existing rectangular or hemispherical artificial reefs, but are manufactured in a relatively simple structure such as a hexagonal frame, a house type, or a stepped shape, so that the seaweeds are naturally active. It was to expose a number of problems in terms of efficiency and performance of the habitats and the feeding and hiding facilities of shellfish and fry based on them.

In order to supplement the above problems, a rope artificially implanted with seaweed germination spores in a land tank can be wound around the surface of the reef to install the reef on the bottom of the sea, or to secure a natural active surface of the seaweed. It is known that the size and structure of the reefs is very large and complicated, but in this case, there is an uneconomical problem due to the excessive cost of the work of transplanting the algae and the manufacturing of the reefs and the facilities of the reefs.

In particular, in the state where the concentration (number of objects) of the algae germination spores can be implanted, the germination spores transplanted on the ropes and the like grow normally and have a very low probability of substantially rooting on the surface of the reefs. Since most of the ropes used for transplanting algae are hardly decomposable materials, the ropes should be removed from the sheath after a certain period of time to prevent environmental pollution. In this process, the seaweeds are additionally torn off. It was implicated.

In addition, since most of the marine reefs are installed in shallow shallow waters with a depth of about 10m to 15m, the reefs are often inverted or separated due to waves or tides, which is why Even if the construction and installation according to the plan after a certain amount of time has passed a problem that the artificial reef is inverted and separated and lose most of the function of the reef.

In addition, the conventional marine reefs have been designed mainly considering only the structures necessary for the swelling of algae, there was a problem that the space or passage structure necessary for the hiding and feeding activities of shellfish and fry based on the algae was not reflected. Because of this, even after a long time after the installation of artificial reefs, there was a problem that the culture of shellfish or fish by seaweed was not properly achieved.

In case of installing a conventional marine reef on the bottom of the sea, when the bottom of the sea where the artificial reef is installed does not form a flat ground but various rocks protrude to form an uneven ground, the artificial reef is considered in consideration of blue or algae. There was a problem that it is difficult to install stably, due to this there is a problem that the facilities of artificial reefs are limited by the geographic factors.

In addition, in the process of transporting the reefs manufactured on land for the facility of artificial reefs to the corresponding water, it is preferable to reduce the number of round trips by stacking the artificial reefs in terms of reducing the logistics cost, the conventional marine forest reefs Not only is the volume very large when stacked, it is almost impossible to stack the fish reliably unless a separate fixing means, due to this there is a problem that takes too much time and money due to the transportation of artificial reefs.

The present invention has been made in order to solve the conventional problems as described above, tripod-type marine deforestation in accordance with the present invention is laminated in the form of a connecting plate protruding the algae attachment plate along the support bridge for settlement resistance installed in the form of a tripod Meanwhile, the spacing between the algae attachment plates forms a concealed space for shellfish and fry, so that the surface structure of the reef itself can be simplified while providing sufficient surface structure necessary for the natural activity of various seaweeds. Therefore, the technical task is to reduce the costs associated with the manufacture and facilities of the fish and to significantly improve the ability to create a marine forest by the fish.

In addition, based on the algae that glides and grows along the surface of the reefs, the paths and spaces necessary for the feeding and hiding activities of shellfish and larvae can be more efficiently and organically linked with the algae. After the facility, it is possible to achieve the culture of shellfish and fishes by seaweed quickly and quickly, and based on the tripod-shaped support legs, artificial reefs are not easily turned over and separated by blue or algae. It is another technical task to contribute to the improvement of convenience according to the facility of artificial reefs for cotton and to reduce the logistics cost by stacked transportation of the reefs.

The present invention as a means for solving the above technical problem, and the support plate for settlement resistance arranged in a tripod form at regular intervals, and the connecting plate is installed in a stack along the space corresponding to each of the support legs; And, characterized in that the artificial reef with a bird-attached plate that is fixed at regular intervals along the upper surface of each connecting plate, wherein the upper end of each support leg is integrally connected and installed to form the upper connection, Both ends of each connecting plate is installed integrally connected with the support leg, the spacing between the bird attaching plate is characterized in that to form a concealed space of shellfish or fry.

In addition, the present invention allows each of the algae attachment plate to pass through the concealed passage of shellfish and fry along the longitudinal direction of the connecting plate, while the attachment protrusion for attachment of seaweed along the periphery of the algae attachment plate protrudes It characterized in that it is formed, the lower end of each of the supporting leg is formed so that the locking end is formed, while the lower side of each front of the support leg is characterized in that the projection jaw for the stacking of artificial reefs is formed, respectively While supporting the flow path of the fish is formed through the support leg, characterized in that the algae attachment groove is formed along the outer surface of the support leg.

According to the present invention as described above, it is possible to easily stack two to three artificial reefs to be transported by a trailer or barge, as well as to minimize the volume when loading artificial reefs, thereby artificial fish It is effective to reduce the number of round trips of the trailer or barge required for the second transportation and the logistics cost based on the same.

In addition, even when the artificial reefs are installed on the sea bottom, the tripod-shaped support legs are able to easily install the artificial reefs regardless of the topographical characteristics of the sea bottom. It has the effect of greatly improving convenience according to the facility, and it is possible to easily insert structures such as rocks on the sea bottom into the inner lower space of the artificial reef, thereby providing natural and additional structures for hiding and growing shellfish and fry. It has an effect.

In addition, the overall appearance of the artificial reef including the connecting plate by the support legs arranged in the shape of a tripod has a stable triangular pyramid shape of the lower light strait, so that the artificial reef can There is an effect of preventing the departure, and thus it is effective to fully exhibit the required fishery function even after a long period of time after the installation of artificial reefs.

In the state to prevent the fall and fall of the artificial reefs as described above, there is an effect to provide an excellent food place by sliding and growing with a large number of various kinds of seaweeds on the surface of the algae attachment plate and artificial reefs, By allowing the shells and fry to hide and feed the spaces and pathways necessary for the organic activity, the shellfish and fry escape the eyes of natural enemies, thus making them safer to feed and hide.

In addition, the narrow edge space or the moving passage is provided more sufficiently on the surface of the artificial reef, such as the flow passage of the support leg, while each algae acts as a wall or shading covering the internal space of the artificial reef. Thus, by providing enough space and shading necessary for hiding of shellfish or fry inside the artificial reefs, there is an effect that the various shellfish or fry can be more safely protected and fostered from natural enemies.

As a result, after the establishment of artificial reefs, the composition of marine forests by seaweeds and the cultivation of various shellfish or fishes based on them can be quickly achieved, thereby preventing the deterioration of fisheries caused by bleaching. On the other hand, furthermore, it has the effect of achieving the increase of fishery resources and the ranching of coastal waters, and it is possible to achieve all these functions effectively by the relatively simple fishery structure, so that the optimum marine artificial reef with excellent economy and functionality It can have a very useful effect such as to provide.

Hereinafter, with reference to the accompanying drawings, the tripod type marine forest reef in accordance with the present invention will be described in detail.

As shown in FIG. 1, the tripod-like marine reef 10 according to an embodiment of the present invention has a support frame 1 for settlement resistance disposed in a tripod form at regular intervals as a base frame. In the space corresponding to each of the supporting legs (1), a plurality of connecting plates (2) are installed in a stacked manner, along the upper surface of each connecting plate (2), the bird attachment plate (21) at regular intervals It is fixed and installed.

Although the support legs 1 are illustrated as having three legs arranged in a tripod shape in the drawing, the number of support legs 1 may be arranged in a minimum of three to a maximum of five, and a support leg 1 Although the structural strength of the artificial reef (10) is increased with increasing number of), the support area (1) is increased by 6 because the sliding area of the seaweed by the connecting plate (2) and the algae attachment plate (21) is relatively reduced. It is not desirable to install more than two in consideration of the production cost aspect of the reefs and the functional aspects of forming the deforestation.

In addition, by reducing the number of the support legs 1 to 3 while ensuring the structural strength of the artificial reef 10, to contribute to the time and cost savings associated with the manufacture of the artificial reef 10, at the same time, the connecting plate (2) and the upper end portion of each support leg (1) so as to secure the maximum space between the algae active area, that is, the support leg (1) by the algae attachment plate 21 to improve the composition capacity of the sea While forming the upper connection portion 12 is preferably to be connected integrally installed.

The upper connecting portion 12 serves as a load support point for substantially supporting the overall load of the artificial reef 10 applied through each support leg 1 arranged in a tripod shape, the artificial reef 10 In the case of pouring and curing of concrete for the production of), it is preferable that each support leg (1) part is integrated by a reinforcing material (deformed rebar, etc.) in the formwork.

As described above, the upper connecting portion 12 to which each supporting leg 1 is connected may also be provided with a narrow edge space for hiding shellfish or fry and a surface for sliding of algae, each supporting leg 1 While having a rectangular pillar shape, it is preferable that the upper surface of the upper connecting portion 12, that is, the top end surface of the artificial reef 10 to form a flat portion.

However, the support leg 1 may be formed of a circular pillar or a triangular pillar or a hexagonal or octagonal pillar as needed, and, of course, when the artificial reef 10 of the present invention is installed on the sea bottom, the supporting leg 1 It is preferable to form the lower end of each support leg (1) with a pointed penetrating blade so that the lower end of the bottom end can be easily dug into the rock or the ground of the sea bottom.

As shown in FIG. 2, the tripod-type marine deforestation reef 10 according to another embodiment of the present invention allows each support leg to be formed with a locking end 13 inside the lower end of each support leg 1. The lower side of the front surface of the (1) is formed so that the protruding jaw (15) is caught to the engaging end portion 13 of the support leg (1) located at the top when the artificial reef (10) is stacked, the support leg (1) A bird attachment groove 14 is to be formed along the outer surface (front side in the drawing) of the incision.

In another embodiment of the present invention, the most important part is, based on the deforestation fishes 10 according to the embodiment, the stacking operation of the artificial reefs (10) on each support leg (1) to be a base frame The hooking end 13 and the protruding jaw 15 for assisting are additionally formed, and the rest of the structure except for the structural change of the support leg 1, that is, will be described later including the bird attachment groove 14. Losing connection plate 2 and the algae attachment plate 21, etc. means that they can be used in combination with each embodiment (混用).

In other words, the largest measure that distinguishes one embodiment shown in FIG. 1 from another embodiment shown in FIG. 2 is a locking end 13 and a protruding jaw 15, and the rest of the rest of the configuration is divided into embodiments. It means that it can be applied irrespective of, and the shape and position of the locking end 13 and the projection jaw 15 and the position and spacing of the bird attachment groove 14 is also not limited to the form shown in FIG. It is to be noted that the manufacturer can change it at will.

In addition, as a component corresponding to another essential part of the present invention, the connecting plate 2 which is installed in a stacked manner along each support leg 1, the upper connecting plate 2a and the intermediate connecting plate ( Three connecting plates 2 composed of 2b) and a lower connecting plate 2c are integrally installed between the supporting legs 1 and the supporting legs 1, and an upper portion of the connecting plate 2 is provided. The bird attachment plate 21 is fixedly installed on the surface.

When the connecting plate 2 is stacked and installed along each support leg 1 as described above, as shown in FIGS. 3 and 4 more clearly, the intermediate connection from the lower connecting plate 2c. As the plate 2b and the upper connecting plate 2a are disposed in the shape of a cover covering the inner space of the artificial reef 10, the shell and the fry of the shellfish and the fry inside the supporting leg 1 and the connecting plate 2 are fed. Provide space for activities.

In other words, in the initial installation of the artificial reef (10), even if each connecting plate (2) is spaced at a predetermined interval, each of the connecting plate (2) and the algae attachment plate (21) is affixed to the predetermined algae When grown to the length of, the gap formed between the connecting plate (2) can be covered by the algae, thereby the house type (House type) hiding space that the algae as a wall or awning inside the artificial reef (10) This can be provided.

Considering that the house-type hiding space as described above is formed inside the artificial reef 10, each support leg 1 has a flow passage 11 of shellfish or fry at a position excluding a connecting portion of the connecting plate 2. It is preferable to form the through, the flow passage 11 may also be formed in a variety of other shapes, such as circular or triangular or hexagonal or octagonal passages in addition to the square-shaped passage shown in the drawings, the flow passage Of course, the direction in which the 11 is formed may also be forward, backward or left and right directions.

However, it is preferable to form each of the flow passages 11 in a triangular or square passage so that a narrow corner space for concealing shellfish or fry can also be provided inside the flow passage 11. In order for the passage 11 to be easily covered by the seaweed, it is preferable that the passage direction of the flow passage 11 be in the left and right directions of the support leg 1, and each support leg 1 as necessary. It is also possible to form two or more flow passages 11 for each).

In addition, although the connecting plate 2 is shown to be installed to form three layers between each support leg 1 in the drawings, the number of installation of the connecting plate 2 can be adjusted from a minimum of two to a maximum of four. Of course, the structural strength of the artificial reef (10) can be improved as the number of connecting plates (2) is increased, but it is uneconomical in view of the actual sliding area of the seaweed and the cost side according to the manufacture of the artificial reef (10). Becomes

In other words, if the number of installation of the connecting plate 2 is increased to five or more, a situation in which the surface of each connecting plate 2 overlaps up and down on the basis of the state shown in FIG. 3 occurs. Because of this, there is a high possibility that the actual swelling and growth space of the algae will be offset by the corresponding overlapping areas, and thus, considering the time and cost aspects of the manufacture of the artificial reef 10 and the functional aspects according to the composition of the marine forest, it is uneconomical. It is.

In the case of the connecting plate (2), the artificial fish is to be integrated with each support leg (1) by reinforcement (deformed reinforcing bar, etc.) in the formwork during the casting and curing of the concrete for the manufacture of the artificial reef (10) It is preferable in terms of securing structural strength of the candle 10, and each connecting plate 2 is provided so that a narrow corner space can be provided even at a portion where each connecting plate 2 is connected to the support leg 1. It is desirable to form a rectangular plate (trapezoid on drawing) shape.

In addition, along with the structural strength reinforcement side of the artificial reef 10 according to the installation of the connecting plate 2, the weight of the connecting plate 2 of the concrete material and the weight of the algae attachment plate 21 and various external pressures As shown in FIGS. 1 to 3 more clearly, each connecting plate 2 is convex toward the upper direction so as to prevent the connecting plate 2 from being broken or broken while sagging in the downward direction. It is most preferable to bend in an arch shape.

In addition, in the case of the lower connecting plate (2c) of the connecting plate (2) it is preferable to install at a height of about 50cm ~ 1m 20cm from the lower end of the support bridge for settlement resistance (1), the reason of the present invention When the artificial reef 10 is installed on soft ground such as sand, sand or nizil, the lower end of the support leg 1 goes to the seabed to a certain depth. This is because it is possible to prevent the composition function of the detrimental forest by the connecting plate 2 from being lowered even if it is settled.

In addition, the algae attachment plate (藻類 附着 板) 21 is installed at regular intervals along the upper surface of the connecting plate (2) is a variety of seaweed along with the algae attachment groove (14) of the support leg (1) In order to provide a practical and effective protruding surface structure on the artificial reef (10) and to provide a practical and effective concealed space (22), such as shellfish and fry feeding algae, An exemplary configuration is shown in FIGS. 5A and 5B.

The most preferable form of the algae attachment plate 21 that can be applied to the present invention is a semi-circular form as shown in (a) and (b) of Figure 5, in addition to the square plate, triangular plate or polygonal plate, etc. It can be applied to the attachment plate 21, of course, the space between the bird attachment plate 21, the concealed space 22 in the drawing to have a spacing of about 5cm ~ 10cm suitable for hiding and moving shellfish or fry. It is preferable.

In addition, it is preferable that the thickness of the algae attaching plate 21 is about 5 cm corresponding to the width of the root of the kelp or seaweed, etc., the algae attaching grooves 14 formed on each support leg (1) The spacing is also preferably about 5 cm corresponding to the root width of kelp or seaweed, and the bird attachment grooves 14 are particularly capable of providing a hiding space such as a young clam. It is desirable to make the incision width about 2cm ~ 4cm.

In the drawing, a plurality of algae attaching plates 21 are installed at the center of the upper surface of the connecting plate 2, and the algae attaching plates 21 are not installed at both ends of the connecting plate 2, which is supported. As both ends of the connecting plate 2 connected to the bridge 1 are gradually formed in a narrow width, due to the situation that the installation and regular arrangement of the algae attachment plate 21 due to the casting and curing of concrete becomes difficult will be.

However, the plurality of algae attaching plate 21 having a smaller size may be fixedly installed at regular intervals on both sides of the upper surface of the connecting plate 2 as well as to each of the algae attaching plates 21. While additionally forming a concealed passage 23 for the movement and concealment of shellfish and fry, while additionally forming an attachment protrusion 24 for easy sliding of seaweed along the periphery of the algae attachment plate 21. Most preferred.

The concealed passageway (23) is a variety of shellfish and fry along the concealed space (22) formed between the algae attachment plate 21 to facilitate the feeding and stealth activities by algae, algae It is preferable not only to form a step with the connecting plate 2 at the lower end of the attachment plate 21, but also to form a hole having a diameter of about 5cm corresponding to the gap between the bird attachment plate 21.

In addition, in the case of the attachment protrusion 24, so that the roots of the seaweed can be more firmly and easily sticking, protruding to form a gear (cogwheel) at regular intervals along the circumferential portion of the bird attachment plate 21 Most preferably, the position and number of the concealed passageway 23 and the shape and spacing of the attachment protrusions 24 are matters that the manufacturer can arbitrarily adjust.

In the manufacturing of the tripod type marine reef 10 according to the present invention, the substantial dimension thereof is about 5m in the case of large reefs, while about 2m to 2m 50cm in the case of medium and small reefs. The thickness of the support leg 1 is about 30 cm, and the width and thickness of the connecting plate 2 are about 50 cm and 20 cm, respectively, and the thickness and height of the bird attachment plate 21 are about 5 cm and 25 cm, respectively. The gap between the tidal attachment plate 21 and the diameter of the concealed passageway 23 is about 5 cm to about 10 cm as described above.

However, the above-described design dimensions include the depth of the coastal sea where the artificial reef 10 is to be installed, the ground state of the sea floor that is the facility area of the artificial reef 10, and the blue or algae in the water body. In addition to the strength of the artificial fish (10) in consideration of the main fish resources and ecological habits to be cultivated by the reefs can be adjusted to various dimensions.

Hereinafter, with reference to the accompanying drawings, the facility and operation relationship of the tripod type marine forest reef according to the present invention having the above configuration will be described in detail.

First, the tripod-like marine reef 10 according to the present invention is supported by a support leg 1 arranged in a tripod shape, and by a connecting plate 2 installed in a stacked manner between each support leg 1, Since the side space is wide and the upper space is narrow, the shape of the Hagwangsanghyup (下 廣 上 狹), two to three artificial reefs (10) can be easily stacked and transported by a trailer or barge, of course When loading the artificial reef (10), the volume can also be minimized.

In other words, when the artificial reef 10 is loaded on a skid of a trailer or a deck of a barge, two to three parts of the supporting leg 1 of the artificial reef 10 overlap with each other. When the two artificial reefs 10 are superimposed, the stacking state of the artificial reefs 10 can be stably maintained even if a separate fixing means is not used, and the end 13 and the protruding jaw of the support leg 1 are supported. In the case of forming 15, the lamination work of the artificial reef 10 can be performed more easily and accurately in a state as shown in FIG.

In addition, as the artificial reef 10 positioned at the bottom when the artificial reef 10 is loaded is inserted into the internal space of the artificial reef 10 located at the top, the volume of the artificial reef 10 may also be increased. It can be minimized, thereby reducing the number of round trips of the trailer or barge required for the transportation of the artificial reef (10) and the logistics cost based on this.

In addition, even when the artificial reef 10 of the present invention is installed on the sea bottom, the lower end of each support leg 1 can easily dig into the gap or the sea bed of the rock existing on the sea bottom to be stably positioned. As it is, it is possible to easily install the artificial reef (10), regardless of the topographical characteristics of the sea floor, thereby greatly improving the convenience of the facility of the artificial reef (10).

In particular, as shown in Figure 3, as the space corresponding between the lower connecting plate (2c) and the support leg (1) can be easily inserted into the structure such as a rock existing on the sea bottom, artificial reef ( 10) of the facility can be further improved, as well as natural and additional structures for hiding and growth of shellfish and fry in the inner lower space of the artificial reef (10) can be located.

In addition, since each support leg 1 constituting the base frame of the artificial reef 10 is arranged in a tripod shape, the overall appearance of the artificial reef 10 including the connecting plate 2 is lowered. 삼각 上 狹) has a stable triangular pyramid shape, and thus the situation that the artificial reef (10) installed on the sea bottom is not easily conducted or separated by blue or algae.

Therefore, even after a long period of time after the installation of the artificial reef (10), the artificial reef (10) is able to fully exhibit the required reef function in place, as well as the support leg (1) and each connecting plate (2) In the process of smooth communication of birds through the gap formed between the), various seaweeds can easily grow and grow on the algae attachment plate 21 installed along the upper surface of the connecting plate (2), while the support bridge Various algae can also glide and grow along the algae attachment grooves 14 formed on the surface of (1).

As described above, the seaweeds and the fry based on the seaweeds in the state to provide a good feeding place of shellfish or fry by sliding and growing in a large number of various kinds of seaweeds on the surface of the artificial reef 10 according to the present invention as described above Since the concealed space (22) and the concealed passage (23), etc. necessary for hiding and feeding activities are organically connected and arranged with the algae attaching plate (21), shellfish and fry avoid the natural eye's eyes for safer feeding. And stealth activities.

In addition to the concealed space 22 and the concealed passage 23 as described above, the flow passage 11 and the upper connecting portion 12 of the supporting leg 1 and the connecting portion of the supporting leg 1 and the connecting plate 2 are also narrow. While sufficient corner space is provided, algae slid to grow on the algae attachment plate 21 serves as a wall or shading covering the inner space of the artificial reef 10, and also inside the artificial reef 10. By providing enough space and shadows for the hiding of shellfish and fry, various shellfish and fry can be protected and nurtured more safely from natural enemies.

Due to this, the composition of the marine forests by the seaweeds and the resource culture of various shellfish or fish based on the marine forests after the facility of the tripod type marine forest reef 10 according to the present invention can be achieved quickly in a short time. In addition, it is possible to suppress the deterioration of fisheries caused by bleaching, and furthermore, to increase the fishery fishery and the ranching of coastal waters.

In addition, all of the above-described functions are supported on the support legs (1) arranged in a tripod shape, the connecting plate (2) installed in a stacked manner between the support legs (1), and the upper part of the connecting plate (2) Since it can be achieved by a relatively simple reef structure consisting of a bird-attached plate 21 installed along the surface, the optimum tripod type deforestation can be greatly improved while the manufacturing cost of the reefs can be greatly improved. Echo 10 will be able to be provided.
