Description

An artificial reef for purifying sea water and making sea weed field}

The present invention relates to an artificial reef block having a shell made of porous concrete having continuous pores on the outer surface of the reef block as well as water purification in coastal waters.

Artificial reef blocks are structures that are artificially installed in the ocean to enable them to be used as habitats for aquatic life, especially fish and shellfish and benthic life.

Conventionally, artificial reef blocks made of general concrete containing cement and sand have been mostly. Artificial reef blocks made of ordinary concrete have little continuous pores in the reef blocks themselves, making it difficult to attach and inhabit seaweeds and have no ability to purify seawater. Therefore, when the water quality of the coastal waters is contaminated, the algae and fish and shellfish cannot live, and thus cannot function as an artificial reef block.

On the other hand, artificial reef blocks made of porous concrete as a whole are not suitable for long life due to their low durability due to the characteristics of porous concrete. It loses its function as.

Therefore, it has the function of purifying water quality at the same time as the habitat of the seabed organisms, and it can be expected to have a long life due to improved durability, and plankton and algae, which are food for fish and shellfish, are easily implanted or multiplied to protect and feed and rest of fish and shellfish. There is a need for artificial reef blocks that can provide.

The present invention was devised in consideration of this point. ① It can be provided as a habitat for maximizing the attachment and reproduction of seaweeds and shellfishes. ② It can purify seawater by artificially formed continuous voids. ③ Echo block due to algae and blue waves. Forming shell made of porous concrete outside the body made of ordinary concrete to prevent the loss of material, especially when the joints installed at the three corners of the reef block are bound together to form artificial reef group, it is possible to obtain great stability in the seabed. The objective is to provide artificial reef blocks useful for the conservation of marine ecosystems and the protection of marine resources.

Artificial reef block of the present invention for solving the technical problem is characterized in that the shell (shell) made of porous concrete is installed on the outer surface of the body made of ordinary concrete. (Claim 1) Here, the porous concrete is the inventor The porous concrete disclosed in Japanese Patent Application No. 490919 may be used.

The artificial reef block or the body may be made in the form of a box or generally known artificial reef block as in the prior art, but not to fall easily by an external force such as algae or blue in the state placed on the sea floor. It is desirable to be manufactured in the shape of a structurally stable triangular pyramid (claim 2).

In addition, it is recommended to install a moving ring at the top of the body or the upper block so that it can be easily lifted by a crane when it is dropped onto the seabed or when moving from place to place on the ground. It is preferable to form a connecting ring that can bind to each other at the bottom of the body so as to (claim 3).

In addition, in the case of forming ① a plurality of dimples (grooves), ② forming a plurality of protrusions, or ③ mixing dimples and protrusions in an appropriate ratio on the surface of the artificial reef block or shell (shell), the specific surface area is widened to the seaweed ( (Days 4 to 6) In this case, the dimples and the projections can be arbitrarily determined by the manufacturer, as well as the depth of depression and the height of the protrusions.

Hereinafter, an artificial reef block according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Example

1 is a perspective view of an artificial reef block according to an embodiment of the present invention, Figure 2 is an exploded perspective view of Figure 1, Figure 3 is a plan view of Figure 1, Figure 4 is a front view of Figure 1, Figure 5 is an artificial An example of an artificial reef group connecting a plurality of echo blocks is shown.

In Fig. 1, the flat plate-shaped cell 1 is made of porous concrete artificially giving continuous pores, through which water and microorganisms can pass, and plants such as algae take root and grow. Done. In addition, the growth of microorganisms between successive pores produces the same effect as a natural purification facility in a river, thereby purifying seawater, thereby reducing water pollution in coastal waters.

On the other hand, the body (2) manufactured in the shape of a triangular pyramid is made of general concrete, which is heavier than porous concrete, to prevent the loss of the echo block due to the weight reduction when the entire echo block is made of porous concrete. In other words, a structure having a large stability capable of responding to algae or blue is provided.

In addition, when installing or dropping the Echo block in the coastal waters because it is impossible to move by manpower and difficult to install, the mobile ring 8 is installed on the top of the body (2) is mounted on the crane winch Hooks, etc. can be hooked to facilitate the installation work. In addition, at the three corners of the lower end of the body (2) is provided with a support (4) having a connecting ring (6), respectively, when these connecting rings (6) to each other can be obtained very large stability in the seabed. In particular, between the support (4) formed in the lower end of the body (2) is not only a movement path of the fish and shellfish, but also a lot of room to be used as a spawning space, to form an environmentally friendly artificial reef group that can be preserved in various marine ecosystems Can be.

Here, in the present embodiment, an anchor bolt-type coupling screw 7 is used as a method of integrating the cell 1 into the body 2, and as a method other than this method, the body is cured with general concrete and then It is also possible to use a method of pouring porous concrete to integrate it.

On the other hand, the six hemispherical protrusions 5 protrude on the surface of the cell 1 of the present embodiment, and a considerable number of dimples 3 are formed on the rest of the cell 1, so that the specific surface area is very wide. Therefore, compared to the artificial reef block of the conventional configuration, not only the adhesion of the seabed plants is very good, but also the contact area with the sea water is remarkably widened, and when the microorganisms are propagated between the pores, Can be purified.

In addition, by using the connecting ring (6) in the three corners as shown in Figure 5 to integrate each of the reef blocks with each other, it is possible to prevent the loss and individual departure of the reef block due to algae and blue, etc. Greater stability can be ensured.

As described above, the present invention is an artificial reef block combining a body made of general concrete and a shell made of porous concrete to improve the attachment and reproduction of algae and fish and shellfish, and to form the artificial reef group between the bottom of the reef block and the bottom of the reef block. The space reserved can be used as habitat for undersea organisms.

In addition, by forming artificial continuous voids and by creating a myriad of dimples (grooves) and protrusions on the outer surface of the artificial reef block to enlarge the specific surface area, the adhesion of the seabed living organisms and the possibility of habitat is maximized, as well as the circulation of water to the continuous voids Since seawater has a function to be purified, there is an advantage to form a concrete structure to reduce the environmental load.
