Description

Coastal erosion prevention block {BLOCK FOR PREVENTING COASTAL EROSION}

The present invention relates to a coastal erosion prevention block, and more specifically to a prefabricated block for coastal protection that protects the coastline of a beach from erosion by waves and currents.

In general, coastal erosion prevention blocks are structures installed in coastal waters to prevent coastal erosion by attenuating the movement of seawater invading the land. In addition, coastal erosion prevention blocks allow various types of seaweed to attach and grow, and are also used as habitats for fish, spawning grounds, and growth centers for fry. In other words, in the vicinity of the coastal erosion prevention block, upward and downward currents occur along the terrain and nutrients are transported to the upper layer where sunlight reaches the surface. As plankton proliferates in the upper layer, small fish that feed on it gather, and large fish target it. By gathering together, a good fishing ground is formed.

This coastal erosion prevention block is a structure manufactured using concrete and is formed in the shape of a long rectangular pipe or block, and has multiple water passage openings on the sides to allow sea water to pass through.

However, the coastal erosion prevention blocks have the problem of being difficult to stack on top of each other, and also have the problem of easily falling over or moving due to the strong external force of seawater or waves.

Therefore, we would like to suggest a plan to solve this problem.

Meanwhile, the present invention is not particularly limited, but as shown in Figures 3 and 4, the coastal erosion prevention block 10 according to an embodiment of the present invention has a thickness of the outer wall forming the edge, other than the edge. It may be thinner than the thickness of the inner wall. Here, the outer wall may refer to a wall provided on the outside of the coastal erosion prevention block 10, and the inner wall may refer to a wall of the coastal erosion prevention block 10 excluding the outer wall.

At this time, the present invention is not particularly limited, but preferably the thickness of the inner wall is twice the thickness of the outer wall.

This is because, as will be described later, the coastal erosion prevention block 10 with a triangular fractal structure, when a coastal erosion prevention block 10 with another triangular fractal structure is combined with one side of a triangle, multiple coastal This is because all inner walls except the edges of the structure formed by combining the erosion prevention blocks 10 can have the same thickness.

Of course, on the contrary, in the coastal erosion prevention block 10 according to another embodiment, the thickness of the outer wall forming the edge may be thicker than the thickness of the inner wall other than the edge.

Meanwhile, on at least one side of the coastal erosion prevention block 10 having a triangular fractal structure according to an embodiment of the present invention, at least one engaging protrusion 111 is formed to protrude, and the engaging protrusion 111 is fitted and coupled.

The two protruding plates (1111, 1112) are spaced apart and arranged parallel to each other, and the free ends of the two protruding plates (1111, 1112) have locking protrusions (1113a, 1113b) protruding outward about the direction in which they are extended. ) can be provided.

At this time, when the two protruding plates 1111 and 1112 arranged opposite each other are pressed in the inward direction, an elastic restoring force is formed in the outward direction, which is the protruding direction of the locking protrusions 1113a and 1113b, and are coupled to the coupling groove 112. When the protrusion 111 is fitted, it is desirable to make the insertion coupling easy but make the separation difficult to secure the coupling.

In addition, the position of the coupling protrusion 111 is not particularly limited, but the coupling protrusion 111 according to an embodiment of the present invention may be provided on the upper end of the coastal erosion prevention block 10, and is attached to the coupling protrusion 111. A corresponding coupling groove 112 may also be provided at the upper end of the coastal erosion prevention block 10.

That is, when the coastal erosion prevention blocks 10 according to an embodiment of the present invention are coupled to each other in the lateral direction, they may have a barbed coupling structure, and accordingly, as shown in FIG. 6, any coastal erosion prevention block 10 can be used to prevent coastal erosion. The block (10a) is laterally coupled to another coastal erosion prevention block (10b), and each of the coupling protrusions (111) and coupling grooves (112) of one coastal erosion prevention block (10a) is, It can be mutually coupled with each of the coupling groove 112 and the coupling protrusion 111 of the other coastal erosion prevention block (10b).

Here, Figures 8(a) and 8(b) are views showing the plane and bottom of the coastal erosion prevention block 10 according to an embodiment of the present invention, respectively, as shown in Figures 8(a) and 8(b). As mentioned, it is preferable that the passage groove (R) formed at the upper end of the coastal erosion prevention block 10 and the passage groove (R) formed at the lower end of the coastal erosion prevention block 10 are not formed on the same wall.

That is, the hatched portion in FIG. 8(a) and the hatched portion in FIG. 8(b) may not share the same wall (inner wall or outer wall).

This is because, even if a plurality of coastal erosion prevention blocks (10) are stacked in various shapes or arrangements, between the lower end of the stacked coastal erosion prevention blocks (10) and the upper end of the stacked coastal erosion prevention blocks (10), they face each other. This is because it is desirable to ensure that the portion is not closed and that as many portions are opened by the passage groove R as possible.
