Description

{Versatile artificial marine structure}

The present invention relates to a multi-purpose marine artificial structure that protects the coast from the flow of seawater and prevents loss of the seashore, and more particularly, to a horizontal multi-purpose artificial structure having a catch function, and attenuates the flow of seawater entering from the sea A multi-purpose marine artificial structure that acts as a submerged and sofa block, protects the coast, prevents loss of the coast, and has a fishing reef function.

Generally, a breakwater is constructed in the area that comes into contact with the sea such as a pier, a port, a coastal area, and a coastal road to reduce the damage caused by waves. Particularly, around the breakwater, the sofa blocks for preventing the wave from directly hitting the breakwater are arranged regularly or irregularly according to the shape thereof. In other words, there is a case where the sofa block is constructed by regular arrangement according to the terrain condition in which the breakwater is built, but there is a case where the soap block in a specific form is built up from the bottom.

The most common conventional sofa block is often called a tetrapod and has a truncated conical shape protruding outward in four directions. As the tetrapods adjacent to each other by the truncated cones formed in four directions are tangled with each other, the tetrapods can be maintained in a state of being constructed for a certain level of external force or less.

As described above, the exemplary sofa blocks are arranged and laminated in a vertical or inclined shape on one side wall of a breakwater constructed by concrete pouring or the like to be fixed to a breakwater.

However, some of the conventional sofa blocks described above have a problem that the energy of the waves coming from the outside sea is lowered, and the sofa function for preventing safety accidents can not be sufficiently exhibited.

In addition, some of the conventional sofa blocks described above have a structure that requires separate fixing means when installed on the side of the breakwater, so that it is difficult to install quickly and stably, or the installation cost is increased.

In addition, some of the above-mentioned conventional sofa blocks exhibit a function of lowering the wave energy to a certain extent, but they are insufficient in functioning as a stable fishing reef in the form of fish and seaweed.

2 and 3, the multi-purpose marine artificial structure 10 according to the embodiment of the present invention is provided on the base plate 100 and is separated from the sofa partition wall 250 by a predetermined distance, The upper and lower portions of the first and second tail wall portions 260 and 270 are integrally formed with the lower portion of the roof plate 300 And left and right tail passages 531 and 532 through which the seawater is moved into a space separated from the first and second tail wall portions 260 and 270 and the sofa partition wall portion 250 can be formed.

Each of the first and second tail wall portions 260 and 270 is symmetrical with respect to the first and third wall portions 210 and 230 with respect to the sofa partition wall portion 250, The first and second wall portions 260 and 270 may be smaller than the first and third wall portions 210 and 230, respectively.

Thus, the first and second tail wall units 260 and 270 are brought into contact with each other through the return flow in which the seawater reduced to the coast returns.

The size of the first and second tail wall portions 260 and 270 may be a reduced size in the longitudinal direction of the first and third wall portions 210 and 230.

The first and second tail wall portions 260 and 270 and the sofa partition wall portion 250 on the rear side of the multipurpose marine artificial structure according to the present invention are caused to rapidly escape due to the bending of the bottom of the seabed after returning to the coast And is guided to the first and second tail wall portions 260 and 270 so as to collide against the rear portion of the sofa partition wall portion 250 so that the speed is lowered and discharged through the left and right tail hole portions 531 and 532, .

The tail of the multi-purpose marine artificial structure according to the present invention can be used to balance the artificial structure by acting as a reaction against collision of the return flow from the back even if strong seawater flows and collides with the front of the artificial structure It also functions.
