Abstract

This invention relates to a novel water ballasted wave attenuator that can be used to diminish or eliminate the impact of waves on shorelines or objects located in or on water bodies. A water ballasted wave attenuator comprising: (a) a hollow shell formed of reinforced concrete; (b) a flotation medium disposed in the upper region of the interior of the reinforced concrete shell (a); (c) an air chamber disposed below the flotation medium (b) in the lower region of the interior of the reinforced concrete shell; and, (d) at least one water vent located in the interior of the reinforced concrete shell (a), said vent connecting the interior of the shell with the exterior of the shell.

Claims

exact text as granted — not AI-modified
1 . A water ballasted wave attenuator comprising:
 (a) a hollow shell formed of reinforced concrete;   (b) a flotation medium disposed in the upper region of the interior of the reinforced concrete shell (a);   (c) an air chamber disposed below the flotation medium (b) in the lower region of the interior of the reinforced concrete shell; and,   (d) at least one water vent located in the interior of the reinforced concrete shell (a), said vent connecting the interior of the shell with the exterior of the shell.   
     
     
         2 . A water ballasted wave attenuator as claimed in  claim 1  wherein the flotation medium is foamed polystyrene. 
     
     
         3 . A water ballasted wave attenuator as claimed in  claim 1  including an air vent which enables air in the air chamber (c) below the polystyrene flotation medium to escape to the exterior of the reinforced concrete shell at the top region of the concrete shell. 
     
     
         4 . A water ballasted wave attenuator as claimed in  claim 2  wherein the reinforced concrete shell has an elongated hollow cubical configuration. 
     
     
         5 . A water ballasted wave attenuator as claimed in  claim 1 , including connection mechanisms for linking together a plurality of wave attenuators. 
     
     
         6 . A water ballasted wave attenuator as claimed in  claim 1  including at least one wave deflector extending downwardly from the base of the attenuator.
