COLLAPSE PROTECTIVE BARRIER FOR PROTECTING SLOPE SURFACE FROM OCEAN WAVE EROSION

摘要

PROBLEM TO BE SOLVED: To provide a collapse protective barrier for effectively protecting a slope surface from ocean wave erosion even below a water surface.;SOLUTION: The collapse protective barrier for protecting the slope surface from ocean wave erosion, is comprised of a grating crib 1, filled mortar 2, and a cut-off underground beams 3. The slope surface 6 is at least partially placed below the water surface. The grating crib 1 is formed of concrete and arranged along the slope surface 6 over a predetermined area. The filled mortar 2 is placed inside frame beams 4 forming the grating crib 1 and adheres to a front surface of the slope surface 6 located below the water surface. The cut-off underground beam 3 is formed of concrete and arranged along the periphery of a grating crib formation region extending over a predetermined area. The cut-off underground beams 3 are constructed at least a part of the slope surface 6, which is located below the water surface.;COPYRIGHT: (C)2003,JPO
