Beach nourish work on shore using bed for wave dissipation having lattice frame and construction method thereof

Year	Description
1997	Invention patented by Kenji Ishikura on August 10th, 1997. Abstract: Beds for wave dissipation having a lattice frame are arranged near a shore line of a shore and wave dissipating materials are stacked on the beds to make a wave dissipating structure, and sand is accumulated on the land side behind the wave dissipating structure. The wave dissipating structure (20) constructed by placing and stacking wave dissipating materials on a lattice frame (10) sinks in proportion to the amount of sand scoured away around the structure or at the bottom thereof, without scattering of the wave dissipating materials by ocean waves, the sinking stops when the effect of ocean waves is not exerted, ocean waves collide with the head part of the wave dissipating structure, crushed waves containing a lot of sand rushes up, and the carried sand is left in backwashing to be accumulated on the land side behind the wave dissipating structure (20). Thus, the sand ground surface (8) rises to a place (9).
