Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete structure used for a wave-dissipating block, a consolidation block, a covering block, and the like, which is installed in a calm area before and after a breakwater, and a method of forming a water area using the concrete structure.

[0002]

2. Description of the Related Art Conventionally, concrete structures have been used as wave breakers in front of breakwaters and seawalls, and also as rooting and covering works to prevent scouring and stabilize foundation rubble. However, conventional concrete structures such as concrete caisson, wave-dissipating block, stiffening block, covering block, etc. have a smooth surface and no irregularities, so there is no stagnation area near the concrete structure. However, there were no functions such as spawning of fish, collecting fish, and formation of water algae.

[0003]

Accordingly, the present inventor has developed a concrete structure used for multifunctional and versatile applications as described above by providing an uneven surface on the surface of the concrete structure to increase the surface area. As a result of various studies to obtain the present invention, the present invention has been completed.

[0004]

That is, the present invention relates to a concrete structure in which a flexible structure having irregularities is provided on a concrete structure and a method of forming a water area using the concrete structure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in more detail with reference to the drawings, but the present invention is not limited only to the following description.

FIG. 1 shows a concrete structure according to the present invention in which a tire is used as a flexible shape having irregularities.
It is a perspective view of the concrete structure A which embedded this.

As shown in FIG. 2, the tire according to the present invention can be suitably used, for example, a tire 1 in a cross shape. In order to fix the cross portion of the tire 1, it can be fixed with, for example, bolts 2 or the like.

FIG. 3 is a plan view showing a concrete structure A when the cross-shaped tire 1 of the present invention is used. That is, the cross-shaped tire 1 is fixed to the concrete structure 3 in a state of being partially protruded. Specifically, for example, concrete is poured into a mold formed into an arbitrary shape, and when the concrete is solidified, the cross-shaped tire 1 is appropriately arranged before the concrete is solidified, and a part of the tire 1 is buried. The concrete structure can be manufactured by solidifying the concrete. Further, when the tire 1 is buried, a reinforcing bar is inserted into the recess of the tire to solidify the concrete, thereby retaining the shape-retaining structure of the tire and holding the tire without detaching from the concrete structure. . The depth at which the cross-shaped tire 1 is embedded may be appropriately adjusted depending on the purpose of use. FIG. 4 shows B in FIG.
It is sectional drawing in the -B 'part.

The concrete structure 3 may be provided with holes 4 as shown in FIG. The location and number of the holes 4 depends on the size of the concrete structure, but it is desirable that the number is large. The shape of the hole 4 is circular, oval,
Polygons such as a triangle, a square, and a hexagon are mentioned, and a hexagonal porous shape is particularly desirable. The holes 4 serve as anti-slip and breeding grounds for water algae when a concrete structure is installed. Further, the hole of the structure is a place for breeding such as rooting of water algae, spawning of fish and collecting fish. The shape of the concrete structure 3 can be various shapes such as a circle, a triangle, a square, a pentagon, and a hexagon. Among them, a hexagon is particularly preferable as the shape of the concrete structure.

The hole 4 of the concrete structure 3 is filled with a stone or the like to which spores of sand / water algae are attached. By doing so, the spores of the water algae propagate on the tire having the uneven shape. The same effect can be obtained by filling a horseshoe-shaped concave portion of a tire with a stone or the like to which spores of sand / water algae are attached. The concave portion of the tire is suitable for implantation of bottoms such as sea urchins, turban shells, abalones, etc. and spawning, and can coexist with water algae.

The concrete structure A is buried in the water bottom by the weight of the concrete structure A in the hole 4 provided in the concrete structure 3, and the hole 4 is filled with sand, earth and sand, etc. Adhering and obtaining an anchor effect. Further, it has an effect of collecting the flowed sand, earth and sand, etc. in the hole 4. In addition, by providing the hole 4 in the lateral direction on the side surface of the concrete structure 3 or the like, the hole 4 can be used as a spawning and collecting place for underwater animals such as fish that inhabit the low-rise area.

Further, in the concrete structure, as shown in FIG. 5, a part of the tire 1 can be embedded in the side surface of the concrete structure 3. By embedding the tire 1 on the side surface of the concrete structure 3, the excavation of the bottom portion due to water spilling under the concrete structure 3 is reduced, and the concrete structure A can be prevented from sinking in one side.

FIG. 6 is a plan view showing a state in which a concrete structure A comprising a hexagonal concrete structure 3 is connected and installed. Of the connecting surface of the concrete structure 3 The reed structures 3 are in close contact with each other and can prevent the outflow of the concrete structure.

Since the tire used in the present invention has a horseshoe shape, the tire has a large stagnation portion and is suitable for spawning fish, collecting fish, and breeding algae. Use of waste tires is extremely advantageous because industrial wastes can be effectively used. Further, in the invention, the tire is suitably used as a flexible shape having irregularities.

In the method of using a tire used in the present invention, a simple substance may be embedded in a concrete structure.
A good result can be obtained by embedding a cloth crossed, a tire connected, or the like in a concrete structure. Furthermore, as shown in FIGS.
In addition, it can be installed in various forms such as parallel, zigzag, spiral, and the like. These concrete structures are excellent as anchor blocks having a buffering property, and are excellent for mooring a pollution control membrane, a sign buoy, a boat, and the like.

FIG. 9 is a state diagram showing a state where a boat is moored to the concrete structure of the present invention.

[0017]

According to the concrete structure of the present invention, a flexible structure having irregularities is provided and a concrete structure 3 is provided.
The holes 4 are filled with sand, earth and sand, and stones to which spores of water algae are attached, and the tires are placed on the upper surface of the holes 4 to form spawning fish, collecting fish, and water algae. Can be used for functional applications. Further, the concrete structure of the present invention is suitable for a multipurpose water area where leisure, such as sightseeing, appreciation, fishing, etc. is added, by being installed in a calm area before and after the breakwater.
