Interlocking segmental retaining wall

Abstract

An interlocking segmental retaining wall. The wall includes a plurality of blocks stack upon each other. Each block includes a void filled with aggregate. In addition, each block includes an extension and slot for interlocking the blocks together to form the retaining wall. Each block also includes a plurality of lugs and an indentation for aligning and stacking the blocks on each other. The blocks may also be stacked to form a curved retaining wall. In an alternate embodiment, the blocks may have tabs located on an upper portion of each block. Each block is laterally positioned by centering the block upon the top of two lower block.

       2 . A retaining wall block for use in forming a retaining wall having at least a lower row and a upper row, said block comprising: 
 front, back, left, and right body portions forming a void within an interior area of the block; and    a plurality of tabs located on an upper surface of said block, said plurality of tabs operable to be received by the void of a block of said upper row, and wherein said plurality of tabs are located rearward of the void of said block.    
   
   
       3 . The block of  claim 2 , wherein said plurality of tabs are substantially rectangular.  
   
   
       4 . The block of  claim 2 , wherein a lower surface of said block is substantially planar.  
   
   
       5 . The block of  claim 2 , wherein said plurality of tabs are operable to receive a portion of a geogrid.  
   
   
       6 . The block of  claim 2 , wherein a front face of said plurality of tabs aligns with a rear interior face of said void.  
   
   
       7 . The block of  claim 2 , wherein the plurality of tabs are arranged laterally between the left and right body portions.  
   
   
       8 . The block of  claim 2 , wherein said front, back, left, and right body portions comprise: 
 exterior side faces; and    interior side faces.    
   
   
       9 . The block of  claim 8 , wherein the plurality of tabs are located forward of the exterior face of said back body portion.  
   
   
       10 . The block of  claim 8 , wherein said plurality of tabs comprise front, back, interior, and exterior faces.  
   
   
       11 . The block of  claim 10 , wherein the exterior face of one of said plurality of tabs aligns with the exterior face of said left body portion.  
   
   
       12 . The block of  claim 10 , wherein the exterior face of one of said plurality of tabs aligns with the exterior face of said right body portion.  
   
   
       13 . The block of  claim 10 , wherein the interior face of one of said plurality of tabs aligns with the interior face of said left body portion.  
   
   
       14 . The block of  claim 10 , wherein the interior face of one of said plurality of tabs aligns with the interior face of said right body portion.
