Abstract
A permeable breakwater for submerged offshore or seawall retentive installation includes a base and permeable opposed sides terminating at an upwardly projecting permeable wave wall. The breakwater is located offshore to cause moderate to heavy waves to break further offshore thereby dissipating their energy before reaching the beach.
Claims18
A reclamation wall disposed adjacent a land-water interface to retain the slit in spoilage placed on the landward side thereof while permitting water to drain out of the spoilage through the reclamation wall to the waterward side thereof, comprising:
- a base;
- a permeable wall projecting upward from one end of said base;
- a retention wall projecting upward from the other end of said base and attached to said permeable wall at its other end;
- said retention wall including a retention means therein for retaining the slit on the landward side of said retention wall and a filter means for permitting drainage of the water out of the spoilage through said retention wall from said landward to the waterward side thereof while retaining slit on said landward side thereof;
- wherein said retention means includes apertures therethrough and a plurality of guides disposed adjacent said apertures for supporting and aligning a plurality of stacked retention blocks which may be located to block said apertures to selectively close said apertures to restrict flow of water therethrough.
A reclamation wall disposed to selectively drain water from solids placed thereadjacent to form a built up land area thereadjacent, comprising:
- a base;
- a permeable wall projecting upward from one end of said base;
- a retention wall projecting upward from the other end of said base and attached to said permeable wall at its other end, said base, permeable wall and retention wall forming the perimeter of a cavity;
- said retention wall including a retention means for retaining the slit on a first side of said retention wall and a filter means for selectively draining the water out of the spoilage through said retention wall from said first side of said retention wall to the other side of said retention wall;
- said retention means includes a plurality of guides thereon for supporting and aligning a plurality of stacked retention blocks thereon;
- said retention wall includes a series of open spaces therethrough including mounting means disposed inward said open spaces;
- and, said retention blocks disposed over said mounting means.
A land building wall for reclaiming land along river, lake and ocean shores by placing water having solids therein on a first side of the wall and permitting the solids to settle out of the water while permitting the water to drain through the wall to a second side of the wall, comprising;
- a wall projecting upward from a base and having a series of vertical slots therethrough having upper and lower termini;
- a support means projecting upward and supporting said wall;
- and,
- fill means for filing said vertical slots to vary the percentage of slot area which is open in comparison to total slot width to permit solids to settle out of the water and build land on the first side of the wall;
- said vertical slots configured to receive said fill means adjacent said lower terminus until the land level on the first side of the wall reaches the upper level of said fill means in said slots when additional fill means may be incrementally located in said slots to further build the land area on the first side of the wall.
