PROBLEM TO BE SOLVED: To provide a precast concrete armor unit for a breakwater, which is excellent in wave-dissipating performance against ocean waves and which can be easily constructed.SOLUTION: A precast concrete armor unit for a breakwater comprises: a central body 110; a plurality of first connection parts that are formed by extending in a radial shape from the central body 110 and that are integrated with the central body 110; a first block 135 that is formed at an end of the first connection part; a second connection part which is formed by extending upward and downward, rightward and leftward, and forward and backward from the central body 110, and which is integrated with the central body 110; and a second block 155 that is formed at an end of the second connection part. Additionally, the first block 135 of one central body 110 and the first blocks 135 of a plurality of other adjacent central bodies 110 are coupled to each other to form a first coupling body. |
