OVERFLOW WAVES-PREVENTING STRUCTURE

PURPOSE:To avoid the interruption of man's vision field as well as raise the economy of the structure by a method in which a projection is provided on the sea surface portion of a wall to be collided with waves in a marine structure by protracting it almost horizontally to the opposite direction of the advancing direction of waves. CONSTITUTION:A highly rigid concrete projection 1 is provided on the sea surface portion of the wall 21 to be collided with waves of a structure 2. In this case, the projection 1 is protracting almost horizontally to the opposite direction of the advancing direction of waves. Waves to ride on the wall 21 of the structure 2 collide with the downside of the projection 1 and U-turns to the opposite direction of the advancing direction of waves, or the direction of separating from the structure 2. As needed, through holes and shock absorbers are provided to absorb the impact energy of waves.
