A protection block at a harbor is provided to improve support rigidity against an external force, and to prevent subsidence and displacement of a wave dissipation block against wave by increasing lateral or longitudinal assembling force of the wave dissipation blocks stacked in multiple steps. A protection block(100) includes a base part(10) constructed in a seabed by rubble; a wave dissipation block(20) cylindrically formed, provided with a body with U-shaped links and first and second prismatic sets(22,23) radially arranged around the body and alternately stacked on the base part; and a clamp(30) combined with the link of the wave dissipation block to connect the laterally arranged wave dissipation blocks. The first and second prismatic sets of the wave dissipation block are contacted to the other prismatic sets of the other wave dissipation blocks stacked to connect the wave dissipation blocks. The clamp has an anchor with three assembling rods fitted to the center and both sides of the links overlapped, a cover having an assembling hole combined with the assembling rod of the anchor, and a fastening nut combined with the assembling rod of the anchor penetrating the cover. |
