Wave absorbing concrete armor stone block for coastal port facilities

摘要

The present invention has a function as a covering stone by replacing and installing natural stone covering stones collected from natural stones by stony mountain development, which is generally used as a covering material installed on the inclined surface of the sloped sandstone of coastal and harbor structures where the stone is mainly constructed. At the same time, the present invention relates to a sofa concrete cladding block for coastal and harbor structures, which also has a sofa effect such as wave dispersion and attenuation.;The upper part of the block has four cylindrical cylinders having a predetermined diameter (D) and a height of 1/2 of the diameter (D), and three cylindrical cylinders having the same diameter as the cylindrical cylinder. In the sofa concrete cladding block consisting of two semi-cylindrical connections, the lower part of the block consisting of two S-shaped horizontal projections and one triangular horizontal projection projecting from the upper portion, One at the center position and one at the vertex position of the equilateral triangle, centered on it, and horizontally integrally connected by the three semi-cylindrical connections between the central cylinder located at the center and the cylindrical column located at the vertex of the equilateral triangle. Is formed in a structure that is connected, the surface of all the connection connecting portion where the cylindrical portion and the semi-cylindrical connecting portion meet each other is formed of a curved surface of a predetermined radius, Two S-shaped horizontal protrusions and one triangular horizontal protrusion are two reverse arcs in which the lower part of the left-right symmetrical connection of the block among the three connections where the semi-cylindrical connection part and the semi-cylindrical connection part meet each other has a predetermined radius. In the S-shape, it is characterized in that the sofa concrete covering stone block, characterized in that the lower portion of the other one connection portion is formed in a projected structure in the form of a two-sided triangle with a predetermined base.
