Description

Reef block

The present invention relates to an ash block, and more particularly to an ash block having increased water resistance, corrosion resistance and high strength and service life.

In general, artificial fish is an artificial structure that is installed in the sea to provide habitat for aquatic organisms such as various fishes, plaques, and algae. It protects the fisheries from the trawler with high fishing ability, It is used for the purpose of nurturing fishery resources by establishing spawning grounds and hiding place for shellfish.

Such artificial fishes can be largely divided into submerged sediments that provide structures on the seabed ground and submerged fish reeds that moor the structures in the seas. In overseas countries, polyethylene terephthalate And various types of fish reefs such as abandoned ship reefs and scrapped reef reefs were used, including prefabricated reefs that consisted of a uniform shape, but the use of waste resources in relation to marine environmental problems is on the decline.

As a typical example of the above-mentioned various kinds of artificial fish super-sediment-type fishing reefs, a square artificial fish sash having a frame structure of a hexahedron shape using concrete and reinforcing bars is a typical example, and such a rectangular artificial fish sash is loaded on a barge The fishermen were then transported to the water area, and then the artificial fishes were laid on the bottom of the sea using a crane installed on the barge to provide spawning grounds and hiding places for fish and shellfish.

However, in the case of conventional simple artificial artificial fishes, when cracks occur, there is a risk of breakage due to penetration of water, and also there is a problem that it is easily corroded or cracked due to weak water resistance.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 to 3, an aseck block 100 according to the present invention includes a block body 110 and a partition member 120 installed inside the block body 110.

The block body 110 is formed in a square pillar shape having an upper surface and a lower surface opened, and has an internal space so that fish and shellfish can be used as spawning ground or concealment space.

The partition member 120 is formed to divide the internal space of the block body 110 into four parts.

The partition member 120 includes a first partition 121 connecting two opposing surfaces of the block body 110 and a second partition 121 extending along a direction intersecting the first partition 121, The first and second compartments 121 and 122 include a first compartment 121 and a second compartment 122. The first compartment 121 and the second compartment 122 collectively form a ten- do.

In the block body 110, first through holes 111 are formed in the side surface so as to communicate with the inner space. The first through hole 111 is formed to penetrate the outer circumferential surface and the inner circumferential surface of the block body 110 and is formed to have a size that allows the fish to be scattered or stealthed to pass through the fish block 100. In the present embodiment, the block body 110 is divided into four parts by the partition member 120, and two first through holes 111 are formed on four sides of the block body 110. Of course, only one through hole 111 may be formed on each side of the block body 110.

The partition member 120 is also formed with a second through hole 123 for communicating each compartment space. The first and second compartments 121 and 122 are provided with second through holes 123 so as to communicate with each other so that the fish and shellfish entering into the block body 110 can move through the adjacent compartment spaces. One hole may be formed, or a plurality of holes may be formed as in the present embodiment. The position, size, and number of the second through holes 123 may be variously formed according to the kind of fish or shellfish to be used in the fish block 100.

The block body 110 and the partitioning member 120 may be integrally formed by curing the concrete 140 or may be formed by separately molding the block body 110 and the partitioning member 120 and then passing through a fastening member such as a bolt Or may be formed by interconnecting them. In this embodiment, the block body 110 and the partitioning member 120 integrally cure the concrete 140, and the coating 130 is formed on the outer peripheral surface thereof.

The coating 130 is formed by using glass fiber to prevent penetration of moisture into the concrete 140 to improve corrosion resistance and water resistance. Of course, the coating 130 may be formed of any one selected from glass fiber reinforced plastic (FRP), polypropylene (PP), and polyethylene (PE) in addition to glass fiber.

The block body 110 and the concrete 140 for forming the partitioning member 120 are formed by mixing cement with aggregates such as sand and gravel and mixing them together with water. In particular, the reinforcing fibers 141 for reinforcing the strength Respectively.

The mixture of the reinforcing fibers 141 is cut into 1 to 3 mm and mixed with water to form a slurry state. The slurry cellulose fibers are put into the concrete 140, The concrete 140 and the cellulose fibers are mixed in a mixer so as to be dispersed appropriately.

The cellulosic fibers may have a diameter of 10 to 20 탆, preferably 14 to 17 탆. The cellulose may be cut so that the number of fibers contained per g is 1,600,000, the density is 1 to 1.5 (g / cm 2), and the surface area of the entire fiber strands per 1 g is 25,000 (cm 2 / g).

Alternatively, the cellulose fibers may be cut to a length of 1.0 to 3.0 mm, a diameter of 5 to 30 μm, and a surface area of 10,000 to 40,000 cm 2 / g, followed by pressing to produce a cellulose compressed fiber sheet. At this time, the number of fibers contained per 1 g of weight may be 50,000 to 3,000,000.

The reason why the cellulosic fiber has a unit length of 1.0 to 3.0 mm is that when it is 1.0 mm or less, a sufficient length required for attachment can not be secured and the reinforcing effect is reduced. When the fiber length is 3.0 mm or more, The surface finish is deteriorated, and the fibers are entangled in the concrete 140. As a result, slump degradation occurs at the same mixed water and cement mixing ratios, so that the amount of mixed water used increases to obtain the same workability. As a result, And the durability is deteriorated.

The reason why the surface area of the cellulose fiber is 10,000 to 40,000 cm 2 / g is that the contact area between the cement paste and the fiber in the concrete 140 becomes smaller when the density is less than 10,000 cm 2 / g, It is difficult to expect. If the surface area is more than 40,000 cm 2 / g, the tensile strength of the unit fiber is decreased due to a decrease in the thickness of the unit fiber, resulting in a decrease in adhesion with the concrete 140.

Therefore, it is suitable for the production of the impact resistant concrete 140 that the cellulose fibers have a diameter of 5 to 30 占 퐉 and the number of fibers included in 1 g is 50,000 to 3,000,000. The cellulose fibers are mixed with 100 to 500 wt% of water based on the weight of the cellulose fibers, mixed in a slurry state, and then spun into a slurry state before mixing with the concrete 140. This is because the cellulose fibers are homogeneously mixed with the concrete 140 This is because the fibers can be prevented from accumulating in the concrete 140 and the mixing time can be shortened when the concrete 140 is manufactured.

The concrete 140 containing the reinforcing fibers 141 is cured to form the block body 110 and the partitioning member 120 and the coating 130 is applied to the outer circumferential surface of the block body 110 to form a reed with improved water resistance, The block 100 may be formed and the ash block 100 thus formed may be submerged in water as shown in FIG. 1 to be used as a spawning ground or hiding place for fish or shellfish.

4 and 5 show a second embodiment of an ash block 200 according to the present invention.

The aspherical block 200 of the present embodiment is formed by assembling the unit members 220 in a rhombic shape to form a body 210 of octahedron having upper and lower surfaces opened.

The unit member 220 is formed in a rhombic shape having a gradually increasing width as it extends from the upper end to the lower end. The body 210 formed with the unit members 220 assembled together has a hexagonal shape with a gradually increasing cross- It becomes a horn shape.

The unit member 220 also includes a base portion 230 cured with concrete containing reinforcing fibers and a coating 240 formed on the outer surface of the base portion 230. The concrete constituting the base portion 230 Since the constitution of the mortar and the coating 240 is the same as that of the previous embodiment, detailed description is omitted.

In addition, the unit member 220 is formed at one side edge of the lead-in groove 250 to be fastened to each other, and the other side edge thereof is formed with a fastening protrusion 260. When the unit members 220 are adjacent to each other to be assembled, the fastening protrusions 260 of the unit member 220 of one unit are inserted into the fastening grooves 250 of the adjacent unit member 220 of the adjacent unit and fastened.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
