Porous underwater breakwater for preventing shore erosion and forming a fishing ground, and method for producing environmentally-friendly blocks for the underwater breakwater

Abstract

The present invention relates to a porous underwater breakwater for preventing shore erosion and forming a fishing ground, and to a method for producing environmentally-friendly blocks for the underwater breakwater, wherein the underwater breakwater is formed by the environmentally-friendly blocks made of a mixture of effective micro-organisms (EM) and red clay such that valleys and ridges are formed on a seabed of a sea area, to thereby purify water and to prevent red tide outbreaks, and thus achieving early marine afforestation, and wherein the wave energy of swelling waves is absorbed, dispersed, and diffracted at a base layer, an intermediate layer, and a top layer of the breakwater to decrease the wave energy and to thereby significantly decrease a gap between wave heights and restore an eroded area by means of beach nourishment. According to the porous underwater breakwater for preventing shore erosion and forming a fishing ground and the method for producing environmentally-friendly blocks for the underwater breakwater, an energy-absorbing unit formed by stacking multiple blocks on the seabed of the sea area absorbs, disperses, and diffracts the wave energy to effectively decrease the wave energy, and fish can migrate through the pores, the sizes of which correspond to the length of pore-maintaining protrusions formed at each block and communicating spaces, thereby providing a fish habitat and spawning ground. Further, the effective micro-organisms and red clay mixed with concrete mortar neutralize the toxicity of the concrete, purify water, and prevent red tide outbreaks.

Description

technical field [0001] The present invention relates to a submerged dike that reduces the wave force of waves and prevents coastal erosion, and in particular relates to a multi-valley porous submerged dike and an environmentally friendly block for submerged dikes that have the following functions and are used to prevent coastal erosion and form fishing grounds Production method. That is, in order to form peaks while forming valleys on the seabed surface in coastal sea areas using eco-friendly blocks formed by mixing Effective Microorganisms (EM, Effective Micro-organisms) and loess when forming concrete mortar, a plurality of blocks are used to form Submerged dikes, thereby purifying water quality and preventing red tides, thereby accelerating the formation of marine forests, while absorbing and dispersing wave energy of swell waves and diffracting swell waves in the bottom layer, middle layer, and upper layer respectively, thereby reducing wave energy , so that not only can ...

Problems solved by technology

[0004] However, although the breakwater building has the advantage of providing resting spaces such as fishing places accessible to ordinary people, it is structurally poor in absorbing and dispersing wave energy, so that waves hit the breakwater building and are reflected to form Standing waves, which can cause severe erosion, and in severe cases, the breakwater structure will be destroyed and lose its function

[0005] Also, the breakwater building is constructed to protrude above the water surface, thus destroying the natural landscape and failing to contribute to regional economic development due to the loss of tourism resources
