Abstract

PURPOSE: To obtain a wave-breaking block of a high and stable wave-breaking effect by forming a triangular block having three inclined feet whose end portions are crossed mutually and projectingly at specific intersecting angle and also forming a space inside.
CONSTITUTION: In a triangular block consisting of the first, second, and third block feed 1, 2, and 3, whose respective both end portions are crossed projectionally at 60° to form a space 4 inside, the block feed 1, 2, and 3 are mutually crossed in such a way that their respective upper portions are crossed with their respective lower portions. The porosity of the wave-breaking block is as high as 65%, and therefore, a high wave-breaking effect can be obtained. Also, because the crossing points of the three feet constituting the wave-breaking block are separated from each other, the gravity center of the block is low and stable.
