EROSION PROTECTION BLOCK AND ARRANGEMENT STRUCTURE THEREOF

摘要

The present invention relates to an erosion protection block and an arrangement structure thereof. A first body part of a plate type is formed from one side toward the other side in the longitudinal direction, is gradually reduced in thickness, and extends in the width direction with the same thickness. Two protrusion parts for connection in the first longitudinal direction protrude at the edge of the other side of the longitudinal direction of the upper side of the first body part toward the upper side in the width direction, a first empty space is formed between the two protrusion parts for connection in the first longitudinal direction, a width direction cross section structure has a hemispherical form at the upper part in order to form an eddy at one side of the longitudinal direction of the first body part and has a first eddy forming part formed on the lower side to a height corresponding to the height of the upper side of the other side of the first body part. The upper side of the first eddy forming part is continuously connected with the upper side of the first body part. The lower side of the first eddy forming part is connected from the lower side of the first body part in the form of stairs. A first groove part for connection of the longitudinal direction to which the protrusion of another erosion protection block is inserted is formed on the lower side of the first eddy forming part. A first protrusion for connection of the width direction protruding in one side direction is formed on one side of the first body part, and a first groove part for connection of the width direction to which the first protrusion for connection of the width direction of another erosion protection block is inserted is formed in the other side of the first body part.
