         The present invention is that facilities such as coastal roads, residential areas, or agricultural lands installed adjacent to the coastline are eroded by the waves of waves periodically generated at sea, resulting in the loss of facilities and economic damage and encroachment of land. In order to prevent the waves of repetitive waves by installing the shoreline coating structure interconnecting each block with the link ring to include a scour prevention block, a sofa block and a bottom block block in order on the coastal ground formed along the shoreline in order. It is a construction method that prevents the coast from being eroded and protects the facilities at the same time.

       The construction method of the coastline coating structure is to clean up the coastal ground to be installed, and then to install the bottom mat for fine soil sediment prevention on the arranged coastal ground, the scour prevention block, sofa block and a predetermined area from the beach on the bottom mat Each base block is installed, but each of the installed blocks is connected to a connector such as a "U" bolt to maintain flexibility.

       Conventionally, only the sofa block is installed on the coastal ground to reduce the wave power, or the coastline or the embankment is covered with tetraports, sandstones, etc. to prevent the erosion of the shoreline due to the wave. If the ground of the part installed adjacent to the ground is lost, the sofa block is also automatically lost, and it is impossible to effectively prevent the loss due to the wave force generated continuously. Also, the coastline or the embankment is covered or laid with sandstone. Even if the ground is lost due to the waves of waves, installations such as the sandstone or tetra-port, etc. are not interconnected, so that each of them is lost individually, so that the shoreline cannot be effectively protected.

       The present invention has been proposed in order to improve the above problems, the coastline ground from the coastal to the place where the facilities such as the quay, the erosion prevention zone, the front end portion adjacent to the coastline and the middle portion of the sofa area and the lower part of the eyepiece area with facilities. It is divided into three zones, each with an anti-wash block in the erosion zone, a sofa block in the sofa zone, and a foot block in the bottom zone, and these are connected to each other by a connector such as a "U" bolt. If the ground on which the scour prevention block is installed is scoured by the repeated wave force, the scour prevention block installed in the erosion prevention zone, which is the tip part, is leaned forward at a predetermined angle by the weight of the scour prevention block. Interconnect the scour prevention block with a connector so that it has an overall flexure and thus When the block is leaned forward, the whole is gently inclined so that no further scouring is progressed. Also, the sofa block installed in the middle sofa area distributes and reduces wave energy by the sofa protrusion installed on the sofa block. At the same time, the reflected energy of the wave force is remarkably weakened to prevent erosion of the coast and the outflow of soil, and the earth and sand pushed by the wave is caught and deposited on the sofa protrusion of the sofa block, thereby keeping the sofa block stable. The underfloor block installed in the underfloor area is installed in contact with a quay wall installed to protect the facility where the shoreline is installed, and the protrusions are weakened by the sofa block so that the sediment pushed by the waves interconnects the underfloor block. Stone filling is made in the space formed by To ensure that the protection by the coast to coast so that the coating structure is deposited on a minute is to a land facility, and installed on the shore to provide a construction method for preventing the erosion.

       The present invention provides a method for constructing a shoreline coating structure in which the respective blocks are interconnected by using a connector while being installed over a predetermined area in the order of scour prevention blocks, sofa blocks, and bottom blocks on the coastal ground formed along the shoreline. As for

       The construction method of the coastline coating structure is to arrange the shoreline ground to be constructed, and then install the bottom mat for fine soil sediment spill prevention, and install the bottom mat on the shoreline ground where the bottom mat is installed from the shore to the place where the facilities such as the inner wall are located. Each zone is divided into three zones: the erosion prevention zone, which is adjacent to the front end, the sofa area, which is in the middle, and the lowering area, which is the eyepiece, where the facility is located.The erosion prevention block in the erosion prevention area, and the sofa block in the sofa area. In the space, each underlay block is installed, and these are interconnected by a connector such as a "U" bolt to have flexibility, and in the space forming part formed by the protrusion of the underlay block when the underlay blocks are mutually constructed.
