PURPOSE: A unit block for constructing a breakwater and a breakwater construction method thereby are provided to combine the unit block firmly by forming fitting sills in the upper plate and fitting recesses in the lower plate, to prevent marine pollution by activating the tidal current, and to protect harbors and bays stably by reducing wave efficiently. CONSTITUTION: An upper plate(10) is connected to a lower plate(20) by plural columns(30) arranged alternately, and a unit block for a breakwater is manufactured by integrally combining the upper plate and the lower plate with the columns. A fitting sill(15) is formed in the upper plate, and a fitting recess(25) is formed in the lower plate. An uneven part is formed successively in the surface of the column. After laying the foundation, unit blocks are arranged regularly, and vertically or horizontally in the seabed. The unit blocks are arranged in the upper part of the platform, and stacked alternately repeatedly. |
