Abstract

According to an embodiment of the preset invention, the present invention relates to a method for restoring sand erosion using a supporting post structure, wherein the supporting post structure is manufactured on land to be easily constructed and assembled and disassembled, thereby being constructed to be suitable for a natural environment, such as water level, in a costal area. The supporting post structure has a fabricated structure to be manufactured to meet an installation site condition, and the fabricated supporting post structures can be used by being stacked on top of each other and extending forward, backward, leftward, and rightward according to the purpose of use. When seawater moves toward a coast, an upper floodgate installed in the supporting post is automatically closed to make the seawater to flow fast under the supporting post, so that sand is deposited near the coast. When seawater moves from the coast to the sea, the floodgate is opened and the flow speed of seawater is reduced to prevent sand from being deposited. Also, the floodgate moves according to a direction of water flow, so that the floodgate has a size and a shape to be suitable for the natural condition of erosional forms in a coastal area. The supporting post structure can be installed to be fixed or movable depending on a site condition, so that the supporting post structure can be moved when the restoration is completed. The supporting post structure can be removed when the restoration is completed according to the need, can be environmental-friendly by permanently preventing and restoring coast erosion using the supporting post structure left in some sections at the time of completion, and can significantly reduce time and economical costs by shortening restoration period by controlling flow speed according to the size of floodgate.

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a sand-

The present invention relates to coastal sand erosion restoration, and more particularly, to coastal sand erosion in a section where the flow rate of seawater is artificially changed due to a breakwater and a coastal structure installed near a coastal coast, It has been progressed to the danger of human accidents due to sand cliffs deformed by erosion and the collapse of buildings near the coast. In order to overcome these problems, we are trying to solve them by the methods of submerged, coastal, and seaward land. And the ecosystem is destructed due to the change of the coastal beach topography, the sandy erosion restoration method of the present invention is a sandy erosion restoration method in which coastal seawater is eroded and coastal structures are arranged in the seawater, Using the installed gate to the sea The waters close to the coast are closed by the seawater coming into the coast, and the waters are blocked. At this time, the waters are narrowed to the lower part of the wingless structure where the waters are not installed, and many waters are passed through at once to rapidly flow the waters. The seawater exiting from the coast to the sea restoring the coastal sand is related to a sandy erosion restoration method that prevents the sand erosion by reducing the flow of water by opening the water gate.

Generally, a breakwater and coastal structures are installed in order to reduce wave crests on the coast. Therefore, since the coastal sand is eroded, a coastal structure, such as a tetrapod, is stored at a point where the flow rate of the seawater is increased. Although it reduces the flow velocity, there is a limit to prevent sand erosion due to erosion due to the lack of tetraparts per coastal zone. As the seawater flow rate is accelerated due to typhoons, And to prevent natural erosion such as tsunamis. In addition, to solve the coastal sand erosion, concrete structures are installed on the coastal sand to prevent erosion. However, .

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to solve the above-mentioned problems, and an object of the present invention is to provide a water- When a large amount of water passes through a narrow channel below the hull structure, the flow velocity is rapidly shifted. At this time, it is possible to move the sand by moving the sand toward the coast due to the seawater having a higher speed, and the hull structure is a hypothetical structure installed to construct a building or a civil structure, and is composed of a column, a beam, It is a wall-less structure that, when built into the sea, will not interfere with the flow of waves or seawater. Therefore, by installing a hydrological gate in the resistivity state to resist the flow velocity, Since the structure of the shore is prefabricated structure, it can be made considering the natural environment of the coast and the water depth of each section, and the shore produced on the land can be easily used by barge or crane on coastal beach. Fixed installation of the hull structural body Sand erosion and restoration can be done permanently and it is possible to complete the sand restoration in each section by installing it by mobile type using barge or crane depending on the terrain condition and situation, The present invention relates to a coastal sand restoration method capable of shortening a restoration period as needed, thereby reducing a lot of time and cost.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and other matters not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a sandy erosion restoration method for a sandy beach, comprising: a sandy erosion restoration method according to an embodiment of the present invention; part; When the flow rate of seawater is moved to the coast, the upper sluice gate installed on the river is automatically closed, so the sluice gate controlling the flow rate of the seawater to the lower part of the river; A free-form anchor portion supporting a flow velocity resistance applied to the hull when receiving the flow resistance at the hydrological portion; A skid portion that allows the boat to move when the coastal sand restoration is completed; The skid portion is mounted on the lower portion of the hull structural body and can easily remove the hull structural body when the hull structural body is moved. The skid portion can be removed when the hull structural body is fixedly restored.

Also, the above-mentioned frosted structure may have a prefabricated structure that can be manufactured to meet the size and height according to the purpose of installation, and the frosted structure assembled for the purpose of use may be stacked up, down, left, and back.

In addition, the gates mounted on the horseshoe can be used by other methods than the method of installation and installation, and it is possible to reduce and control the flow rate according to the purpose of the gates. The size and shape of the gates are dependent on the natural conditions of the coastal erosion topography It can be manufactured and assembled.

The sand restoration method is classified into three types. The restoration method is to restore the coastal structure from the coast to the sea, to restore from the sea to the coast, to restore the coastal erosion, Which can be categorized in the same way.

The details of other embodiments are included in the detailed description and drawings.

The sandy erosion restoration method according to the embodiment of the present invention as described above is an eco-friendly method because it installs the assembled shore according to the height of the water depth at which the coast erosion occurs, thereby restoring the sand lost by the coast structure, through the restoration of sand by controlling the wave velocity it can be widened coastal sandy areas, and sand piled on route to the ship route due to the erosion of sand will be capable of solving that interfere with the passage, and Shore coastal beaches The structure can be installed as a fixed type, and it can be installed as a movable structure according to the field conditions, so that it can be moved when the restoration is completed. In case of mobile type, it can be removed if necessary after completion of restoration, and it is possible to prevent coastal erosion forever by leaving a hull structure on some sections at the time of completion. Therefore, Therefore, the restoration period can be shortened according to the degree of risk, thereby reducing the time and economic cost.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
