Wave dissipating block and breakwater covered therewith

摘要

The present invention is a covering block of an inclined breakwater to prevent damage caused by waves while dissipating and absorbing waves from the shore. is a block In the present invention, four outer supporting pillars are vertically erected to form a quadrangle with each other in the form of a cylinder on the upper surface of a base plate that is horizontal in the form of a quadrangular plank board, and the central part of the four outer supporting pillars is parallel to the base plate A central column is vertically erected horizontally, and an intermediate slab plate is installed in the form of a quadrangular plank on the upper portions of the four outer supporting columns and the central column, and on the four sides of the base plate and the intermediate slab plate, a plurality of When the sofa blocks are mounted so that they are in contact with each other, concave grooves that are concave in a trapezoidal shape are formed between the sofa block and the sofa block, respectively. A central space concave in the form of a quadrilateral is provided in the central part between the quadrangular wall and the upper surface of the intermediate slab plate, and a wall water hole is formed through the wall of the quadrangular wall so as to communicate with the central space part, , A wave discharge hole is formed by penetrating the intermediate slab plate up and down, and one side is in contact with the inner wall surface of the quadrangular wall so as to be located in the central space portion and the other side is penetrating in the form of a long direction to face the central portion, At each corner of the tetragonal wall, a quadrangular protrusion of a trapezoidal shape gradually narrowing toward the end is protruded, and the center protrudes to form an angle of 45° with the tetragonal wall, and the quadrangular protrusion One or two protrusion through holes are formed in the transverse direction, and two wave dissipating protrusions are formed at a predetermined distance from each other on the four upper surfaces of the tetragonal wall and projecting upward in a trapezoidal shape. do. The sofa block of the present invention is a combination of a sofa block and an intermediate covering block by allowing the base plate to replace the intermediate covering block. It has the effect of satisfying both constructability and economy at the same time.
