Description

improved square reef {artificial reef of square type}

The present invention relates to an improved rectangular reef, and more particularly, by improving the conventional rectangular reef structure to prevent subsidence in soft ground, and at the same time to provide a space for fish and shellfish to inhabit, and to protect aquatic resources by creating a marine forest, It is about a square reef that can be nurtured.

In general, artificial reefs are composed of artificial structures for increasing aquatic resources in coastal waters and are provided as spawning or habitat for fish and shellfish, and as a hiding place to protect fry or adult fish.

Such artificial reefs can be expected to have the effect of improving the efficiency of fishing by resource multiplication and swarms of fish groups, and the effect of shortening the operating time due to the proximity of the fishing grounds. In particular, in the sea area where tidal greening (whitening) has occurred, the effect of preventing tidal greening in coastal waters can be expected through the transplantation and cultivation of seaweeds.

Recently, in the coast of Korea, useful seaweed such as seaweed, kelp, and rhubarb that inhabited the coast disappeared due to the succession of seaweed due to the strong Kuroshio warm current, El Niño phenomenon, and other environmental pollution. Lime coral algae reproduce in large numbers, causing a lot of glacial greening (whitening) that covers the bedrock.

Although the exact cause of this bleaching phenomenon has not yet been identified, it is attributed to the spread of the Kuroshio turbulent force and the increase in water temperature due to environmental changes and inhibition of photosynthesis of seaweeds. The bleaching phenomenon is currently rapidly spreading in the East and Jeju coasts, deteriorating coastal aquaculture farms, and rapidly decreasing seaweeds such as seaweed and kelp. The situation is worsening, and the income from fishing in coastal waters is declining.

One of the methods to restore a fishery where bleaching has occurred is to install a reef, an artificial structure.

In general, artificial reefs are divided into coastal reefs installed within 15 m of water and offshore reefs installed at depths of 15 to 70 m. As algae collide with the reef, upwelling currents and turbulences are generated, and through this, nutrients accumulated on the seabed are floated to the upper layer to create an environment where various plankton can reproduce in large quantities, thereby increasing the productivity of coastal fisheries.

There are various types of artificial reefs, and among them, rectangular artificial reefs are representative.

A conventional rectangular artificial reef is disclosed in Korean Patent Registration No. 10-0787828.

The artificial reef has a structure in which the inside is empty in the shape of a hexahedron and holes are formed on each side. These conventional artificial reefs have a small contact area with the bottom, so there is a problem in that they are easily settled in soft ground such as pearl or sand. In addition, there is a problem that it takes a lot of time to create a marine forest.

Hereinafter, an improved square reef according to a preferred embodiment of the present invention will be described in detail.

The improved square reef of the present invention is used for the habitation of fish and shellfish and the composition of the marine forest.

1 to 3, the improved quadrangular reef 10 of the present invention has a body 20 in the form of a hexahedron with an empty interior, an opening 25 formed on each side of the body 20, and the body 20 ) has a protrusion formed by protruding at regular intervals on the slopes except for the front and rear surfaces.

The body 20 is formed of concrete and has a hexahedral structure with an empty interior. Since the inside of the main body 20 is empty, it provides a space for fish and shellfish to inhabit or hide.

In the illustrated example, the body 20 is a hexahedron in which all six faces are quadrangular. Openings 25 are formed in each of the six surfaces of the body 20 . That is, the main body 20 has an opening 25 formed on each side thereof. The opening 25 may be formed in an octagonal or quadrangular shape. In the illustrated example, the opening 25 is formed in an octagonal shape. The octagonal opening 25 may have a larger area without reducing the strength of the edge portion of the body 20 .

The opening 25 is formed in the center of each side of the same size. The main body 20 penetrates in the front-rear direction, the left-right direction, and the up-down direction by the opening 25 . Accordingly, the seafood can freely enter and exit the inside and outside of the body 20 through the opening 25 in any direction. In addition, the circulation of seawater is made smoothly through the opening (25).

The body 20 is formed with a protrusion. The protrusions are provided on all sides except for the front and rear surfaces of the main body 20 , that is, the left and right sides, and the upper and lower surfaces.

The protrusion consists of a plurality of protruding jaws 31 and 35 . Each of the protruding jaws 31 and 35 is formed to protrude outwardly of the main body 20 . The body 20 can greatly enlarge the contact area with the underwater floor by these protruding jaws 31 and 35. When the floor is installed on a soft ground such as pearl or sand, the subsidence of the main body 20 can be effectively prevented by widely distributing the load of the main body 20 . It facilitates in-place seating and ensures stability due to increased ground friction.

The projecting jaws 31 and 35 may be divided into corner projecting jaws 31 and square projecting jaws 35 according to positions.

The corner protrusion 31 is located at the edge of the slope of the main body 20 . In the illustrated example, the corner protruding projections 31 are respectively formed at the four corners where the four sides of the main body 20 are in contact. The corner protruding jaw 31 is formed to be elongated back and forth from the front to the rear of the main body 20 . These corner protruding jaws 31 serve to strengthen the corner portion of the body 20 . Meanwhile, as shown in FIG. 10 , the corner protruding jaws 32 may be formed to be adjacent to the corner with the corner therebetween.

Referring back to FIGS. 1 to 3 , the square protruding jaws 35 are formed between the corner protruding jaws 31 . Square protruding jaws 35 are formed on each of the four sides of the body 20 with the opening 25 therebetween.

In the illustrated example, two square protruding jaws 35 are positioned to face each other with the opening 25 interposed therebetween. These square protruding jaws 35 are positioned so that one side is in contact with the opening 25 . Each of the square protruding jaws 35 is formed in a trapezoidal shape whose cross section is gradually narrowed as it progresses toward the end.

Since a recessed space is formed between the square protruding jaws 35, it is easy to inhabit shellfish such as abalone and conch. The recessed space between the square protruding jaws 35 may also be used as a collection space in which organic materials that are sedimented in seawater are collected. As the organic materials floating in the seawater collide with the body 20 by the current, the organic materials are collected into the empty space between the square protrusions 35 . When organic matter accumulates, plankton that feed on organic matter are gathered, and fish and shellfish, which are top predators of plankton, naturally gather in the square reef 10, providing a food supply for many fish and shellfish.

As such, the present invention can provide a space for fish and shellfish to live or hide while preventing subsidence in soft ground by improving the conventional rectangular reef structure.

On the other hand, an improved square reef according to another embodiment of the present invention is shown in FIG. 4 .

Referring to FIG. 4 , the present invention further includes a seaweed rope 1 to which imitation or spores of seaweed are attached, and a support means installed in the body to support the seaweed rope 1 .

In the illustrated example, the main body 20 and the protrusion are the same as in the embodiment of FIG. 1 described above.

The seaweed rope 1 may use a conventional seedling or seedling rope. The seaweed rope 1 is preferably made of an eco-friendly material such as hemp.

After transplanting the spores or imitation of seaweed into the seaweed rope (1), it is fixed to the main body (20) by a support means. The seaweed rope 1 may be installed before the main body 20 is put into the sea or after the main body 20 is put into the sea.

Seaweeds generally refer to algae such as green algae, red algae, and brown algae that inhabit the sea, and algae refers to mature seaweeds that generate spores. The seaweed rope 1 is fixed so as not to be separated from the main body 20 by the support means.

It consists of a plurality of poles 40 installed on the upper part of the main body 20 as a support means, and a pin (not shown) for fixing the seaweed rope 1 to the pole 40 .

A plurality of seating grooves 45 are provided in the main body 20 , and a square tree 40 is installed inside the seating grooves 45 . The seating groove (45) is formed in the corner protrusion (31) and the square protrusion (35). In addition, it is also formed in the recessed portion between the protruding jaws.

The square wood 40 is installed so as to be buried in concrete in the process of pouring the body 20 with concrete, or after forming the seating groove 45 in the body 20, the square wood 40 is inserted into the seating groove 45 can be installed.

The seaweed rope 1 is fixed to the upper part of the wooden 40 installed in the main body 20 . As a fixing method, the seaweed rope 1 can be fixed by driving a straight pin or a U-shaped pin into the square tree 40 using a taka tool.

As described above, in the present invention, by installing the seaweed rope 1 on the main body 20, the composition of the seajung forest is easy. Accordingly, by creating an environment in which seaweed, shellfish, fish, etc. can coexist, it provides usefulness to improve or restore the aquatic environment.

Another example of the support means is shown in FIGS. 5 to 7 .
