Description

Efficient wave energy reduction shoreline structure {Coastal zone shore protection structure reducing wave energy}

FIELD OF THE INVENTION The present invention relates to coastal zone (i) shore revetment structures. Generally, shoreline structures are constructed on banks such as seashores, shorelines, and riverbanks, or on slopes such as incisions, to prevent erosion. To reduce energy efficiently. More specifically, the present invention relates to a revetment structure for efficiently reducing wave energy in a coastal revetment structure, the shape of an artificial sandstone applied thereto and the construction of the artificial sandstone.

Our country is geographically three-sided, and the sea's multipurpose use is emphasized along with economic growth and globalization. In order to keep related facilities safe in the coastal area, it is necessary to secure the stability of the waves. For this purpose, shoreline structures such as breakwaters and breakwaters are used.

In general, coastal areas are damaged by waves and lanyards, which are damaged by sand dunes, earth and sand, coastal structures collapse, gravelized beach erosion, erosion and sediment imbalance. This serious condition has been reached, and coastal coastal coastal structures have been installed to prevent such damage and protect coastal areas. The method of filling the sandstone in the Yeonak revetment structure has also been used conventionally.

On the other hand, recent changes in the strength and direction of waves, lanyards and coastal streams have occurred due to artificial structures such as breakwaters, wave breakers, and coastal roads installed in coastal areas, resulting in unexpected erosion and deposition. The situation is causing serious damage to coastal areas. Therefore, in order to prevent and protect the damage of the coastal area, researches have been made on the coastal coastal revetment structure and the filled sandstone to reduce erosion and sedimentation by installing a permeable layer such as rubble or gabion in the coastal area.

However, a large amount of rubble or sandstone is used to construct a coastal shoreline revetment structure. However, the sandstone used for the existing shoreline revetment structure is empirically applied focusing on the wear characteristics and weathering degree of the material. There is no direct consideration of the reduction of energy.

The present invention is to provide a more efficient artificial stone shape in consideration of the contact surface of the dead stone and the wave energy applied to the revetment structure. In addition, the present invention proposes a method for installing artificial stone.

The present invention to solve the above problems, the bottom side and the land side vertical side and the sea side hypotenuse and is formed between a plurality of shape maintaining frames and a plurality of shape maintaining frames arranged at regular intervals along the coast Disclosed is an efficient wave energy reducing revetment structure including a plurality of wave energy reducing artificial stone filled in space and efficiently reducing wave energy.

The plurality of wave energy reducing stones that effectively reduce the wave energy, which is the biggest feature of the present invention, are characterized by its shape. Unlike the typical non-standard type of sandstone of the revetment structure, the sandstone is an artificial sandstone, and is characterized by being cylindrical or thin plate type in order to efficiently reduce wave energy . It is more preferable in the case of a thin disk shape which can be regarded as an overlapping region of a cylindrical shape and a plate shape. This is because this type has the largest surface area per unit volume, resulting in a large energy reduction through contact with blue.

In the case of installing the disk-like sandstone as described above, it can be assumed that the disk-shaped artificial sandstone is laid down and installed in the filling space of the revetment structure, and when it is installed upright, it is again parallel to the direction of blue again. It can be divided into vertical arrays and vertical arrays. Due to the nature of the blue, the process of entering and exiting the revetment structure is repeated, and considering the aspect of reducing energy in this process, the disk-shaped stone structure is erected in the arrangement, but the horizontal arrangement is perpendicular to the direction of the blue .

When the disc-shaped artificial stone is installed in a horizontal array as described above, it is installed in a plurality of rows at regular intervals, it is preferable that the disc-shaped stone is arranged in two adjacent rows are not arranged in the same column and alternately arranged . The artificial sandstones are not aligned with each other, but are staggered with each other, so that when the inflow and outflow of the blue waves flow into and out of the heat, the blue energy can be reduced more effectively.

On the other hand, the artificial stone may be formed of a circular plate portion for reducing the energy of the blue through the contact and the fixing projection for fixing to the filling space in order to be installed in the filling space between the shape maintaining frame. More specifically, the bottom plate is formed under the filling space of the frame for maintaining the shape, the bottom plate is formed with fixing grooves at regular intervals, the fixing projections of the artificial stone is fixed to the fixing grooves the artificial It may be characterized in that the dead stone is fixed to the filling space between the shape maintaining frame.

The present invention can effectively alleviate the impact energy of blue waves continuously applied to the shoreline structure to protect the harbor or coastal facilities, and easy installation, maintenance and management by suggesting the installation method of artificial sandstone It can be done.

In order to reduce the wave energy, it is necessary to increase the contact surface between the shoreline structure and the wave. Therefore, the shaped stone having a larger surface area for the same volume can reduce the wave energy more effectively.

Conventional sandstones are generally used after being collected in nature, and most of them are atypical forms. In order to more effectively reduce the wave energy, the present invention discloses a specific type of artificial stone.

Shapes that can be applied to artificial stone, tetrahedron, cube, octahedron, dodecahedron, icosahedron, sphere, cylinder, thin plate thin plate), etc. For each of these, comparing the surface area to unit volume, it can be seen that the thin plate-shaped artificial stone has the largest value. Table 1 below is a table comparing the surface area for the shape compared to the unit volume.

The plurality of wave energy reducing stones that effectively reduce the wave energy, which is the biggest feature of the present invention, are characterized by its shape. Unlike the typical non-standard type of sandstone of the existing shoreline structure, the sandstone of the present invention is an artificial sandstone, and in order to effectively reduce the wave energy, as shown in the above table, it is a cylinder having a large surface area. It is characterized in that the plate (Thin plate) type. It is more preferable in the case of a thin disk shape which can be regarded as an overlapping region of a cylindrical shape and a plate shape. This is because this type has the largest surface area per unit volume, resulting in a large energy reduction through contact with blue. Considering the convenience of construction and aggregate used in the pre-fabrication of concrete in application to general revetment structures, the ratio of the thickness and diameter of the thin disc-shaped artificial stone is 1/18 to 1/22. Preferably, this experiment was based on 1/20.
