Conventionally, in order to overcome the scour phenomenon, artificial maritime work of coastal structures was replaced with high density sandstone. In addition, as shown in FIG. 1, Japanese Unexamined Patent Publication No. 2002-005960 discloses a civil support mat in which a wire net, a synthetic resin net, and various kinds of fiber netting are filled with stones and disposed below the coastal structures.

However, these techniques have caused cost increase and prolonged working period, and have adversely affected ecological environment.

The present invention also relates to a mat block (M) disposed on the front surface of a coast structure to prevent scouring.

Specifically, the mat block M has a rectangular bottom portion 10 parallel to the sea bottom surface. The bottom portion 10 has a protruding portion 20 formed on the bottom portion 10, .

As shown in FIGS. 2A to 2D, the projection 20 may be formed on the mat block M to prevent the submarining of the sea floor. The submarine surface is naturally submerged by the flow of the water, which forms a wavy bend.

The mattress block M is artificially disposed on the seabed surface so that the projection 20 is formed on the mattress block M while the mattress block M Are continuously joined to the adjacent mat block (M) in the length or width direction to form a wavy shape as a whole.

As a result, it is possible to prevent the submergence phenomenon caused by the flow of water on the sea floor, and even if strong wave energy is induced, it is possible to positively prevent the barging phenomenon as a physical barrier.

Further, the bottom portion 10 is formed parallel to the sea bottom surface, so that the bottom portion 10 is brought into close contact with the floor.

The protruding portion 20 of the mat block M may have a tapered rising portion 21 on the side where the flowing water flows and a tapered down portion 22 on the other side to have a triangular cross sectional shape .

The inclined rising portion 21 of the protruding portion 20 is preferably configured such that the flow of the flowing water is guided, and when the inclination is excessively high, the natural flow of the flowing water can be blocked, so that the resistance is small.

In addition, it is preferable that the inclined lowering portion 22 of the protruding portion 20 is formed so as to have a somewhat higher inclination so as to increase the resistance so that the flow of the upper stream can be attenuated, as opposed to the inclined rising portion 21.

In addition, the inclined lowering part 22 also functions to prevent the loss of sea water due to the rainwater, and it is preferable that the inclined lowering part 22 has a high inclination.

On the other hand, the length of the inclined rising portion 21 of the protruding portion 20 may be longer than the length of the inclined lowering portion 22.

This is a difference in shape caused by a difference in function between the inclined rising portion 21 and the inclined lowered portion 22 of the projecting portion 20 described above.

Specifically, it is preferable to form the projecting portion 20 in a wavy shape, and to form the inclined rising portion 21 and the inclined lowering portion 22, it is preferable to form a triangular or streamlined projecting portion 20, The resisting force by the water flow can be adjusted through the length of the hypotenuse of the slope rising portion 21 and the slope descending portion 22. In this case,

On the other hand, a coupling protrusion 23 is formed on the inclined rising portion 21 of the protruding portion 20 and a concave recessed portion 24 is formed on the inclined lowering portion 22, So that they can be bound together.

Specifically, when the wave energy is relatively large and the coast structure is large, a plurality of the mat block M are arranged in the longitudinal direction of the mat block M to form a wide width of the mat block structure S formed by the mat block .

At this time, the coupling protrusion 23 of the inclined rising portion 21 and the coupling recessed portion 24 of the inclined lowering portion 22 are formed so as to correspond to each other, .

A fitting protrusion 25 is formed on one side surface of the protrusion 20 of the mat block M and a fitting recessed portion 26 is formed on the other side of the protrusion 20 to be engaged with the mat block M adjacent in the width direction .

Specifically, the mat block M is disposed on the front surface of the coast structure, and is preferably disposed to correspond to the length of the coast structure.

The fitting protrusions 25 of the protrusions 20 fit into the fitting recesses 26 formed in the protrusions 20 of the adjacent mat block M so that the fitting protrusions 25 of the protrusions 20 are continuously bound And the length of the mat block structure S is adjusted.

The bottom protrusion 11 and the bottom recess 12 may be repeatedly formed on the bottom surface of the bottom portion 10 of the mat block M. [

It is preferable that the bottom portion 10 of the mat block M does not allow the bottom surface and the mat block M to be in close contact with each other and the floor bottom portion 10 and bottom bottom portion 12 are repeatedly formed, so that the bottom projection 11 is inserted into the marine bottom by the own weight, whereby the mat block M is not easily lost or flowed even in strong wave energy.
