Sandbag Wall System With Sandbags Having A Waist Portion

Abstract

The invention provides a sandbag having a waist portion. The waist has a smaller cross-sectional area than the remainder of the bag, forming a bag shape that has greater resistance to movement when embedded in the backfill material supported by a sandbag wall. In use, the sandbags with a waist portion are positioned so as to extend from the wall face into the backfill, thus stabilizing the wall.

1 . A sandbag comprising a bag having a wall, a closed bottom and a closed top, said bag containing a fill material, said bag having a waist.  
   
   
       2 . A sandbag according to  claim 1  wherein said bag has at least two waists.  
   
   
       3 . A retaining wall structure comprising: 
 (a) a plurality of courses of sandbags forming a wall face supporting a mass of backfill, each of said courses comprising a plurality of sandbags;    (b) interconnecting members positioned between adjacent courses to connect sandbags of each course to said sandbags of each adjacent course;    (c) at least one sandbag extending from said wall face into said backfill, said extending sandbag having a waist; and    (d) said extending sandbag being attached by means of an interconnecting member to one or more of said sandbags forming said wall face.    
   
   
       4 . A retaining wall structure according to  claim 3  wherein there is a plurality of said extending sandbags, spaced apart from each other and extending from said wall face into said backfill, said extending sandbags each being attached by means of said interconnecting members to one or more of said sandbags forming said wall face.  
   
   
       5 . A retaining wall structure according to  claim 3  wherein said extending sandbag has two or more waists.
