Marine Structure Assembly for Forming Artificial Fishing Reef and Weakening Wavers for Wave Energy Reduction Caused by Artificial Reef Formation or Erosion and Sand Loss

The present invention relates to an offshore structure assembly for reducing wave energy causing artificial reef formation or erosion and sand loss. Specifically, the present invention relates to the function of an artificial reef that is a habitat for fish or is transmitted to the shore and The present invention relates to a module in an offshore structure assembly for reducing artificial wave formation or erosion that can reduce wave energy that causes sand loss and wave energy that causes sand loss.

Artificial reefs are reefs formed by waste ships or artificial structures that have been put into the sea to allow fish to live or spawn while they are inhabited by seaweed. Artificial reefs may be formed in order to prevent the degradation of the sea due to causes such as a sharp decrease in algae. Artificial reefs can be the basis for ocean forest formation by providing a habitat for fish such as bullocks, reticulated fish or domes.

In general, blue is a wave phenomenon caused by wind at sea level and develops when wind continues to blow in a constant direction. Blue waves can transmit energy along the sea surface to erode the shore, or change the shoreline topography by losing the sand on the shore. On the other hand, various types of infrastructure, such as breakwaters or breakwaters, can be built on the shore or in the shallow waters for sea use. Loss or erosion of sand by blue energy can cause natural disasters, such as erosion or collapse of shores, and can affect the ecological environment and cause environmental degradation, as well as destroy the survival of people living on the coast. . In addition, maintenance costs can be increased due to the erosion of infrastructure built offshore. Therefore, it is necessary to form artificial reefs by the installation of appropriate structures to prevent desolation of the sea and to prevent or mitigate such terrain changes or damage to the infrastructure due to the waves.

As a prior art for preventing terrain changes or damage to infrastructure due to blue waves, there is a patent registration No. 0657180, 'Soil erosion prevention structure on the coast'. The prior art reduces the force of the sea water flowing to the shore and at the same time to install the floating plate to move up and down according to the height of the sea water to effectively stack the float and sand according to the height of the support, support plate, and sea level Disclosed is a coastal soil erosion prevention structure consisting of a floating plate moving up and down and a mesh fixed to the floating plate.

The prior art has the advantage of preventing the drift of sand or floats by back-wash (bash wash) where the sea water is pushed back to the sine, but it reduces the energy of the wave itself, It is difficult to prevent erosion and sand loss. Another problem with the prior art is that it can cause environmental problems later by being installed at sea. Therefore, in order to prevent erosion or sand drift caused by the wave energy and to mitigate changes in the existing coastal environment, the energy of the wave itself can be reduced to effectively block the transmission of the wave energy, and at the same time, for example, due to the installation of the structure There is a need for structures with the ability to create a favorable environment for fish farming.

The present invention is to solve the above problems with the prior art has the following object.

It is an object of the present invention to reduce the wave energy that is installed on the shore or in the shallow sea to prevent coastal erosion or sand loss, and at the same time to form artificial habitats or erosion and sand loss that can create a habitat for fish. It is to provide an offshore structure assembly for reducing the cause wave energy.

According to a preferred embodiment of the present invention, there is provided a unit module comprising horizontally and vertically arranged unit modules, each supporting column supporting one or more precast concrete plates at a predetermined height;
A natural stone disposed to protrude from the precast concrete plate;
