Sandbag Wall Ststem with Multi-Compartment Sandbag

Abstract

A bag for holding fill material for use in the construction of sandbag retaining walls and erosion control has two or more longitudinally-extending compartments formed by a line of attachment between opposed bag wall sections. In use, if one compartment wall fails, the bag as a whole will remain functional within the wall. The compartments can also be filled with different fill materials, for example soil and dry mix concrete, to provide walls having characteristics suited for particular applications.

1 . A bag for holding fill material, said bag being for use in the construction of sandbag walls, comprising a bag wall, a closed bottom and a top edge, said bag wall having opposed wall sections attached together along a line extending from said bag bottom towards said top edge, forming two compartments in said bag that are open to said top edge and adapted to receive said fill material therein. 
   
   
       2 . A bag according to  claim 1  wherein said line of attachment is generally perpendicular to said top edge. 
   
   
       3 . A bag according to  claim 1  wherein said line of attachment is a sewn line. 
   
   
       4 . A bag according to  claim 1  wherein said bag is made of geotextile. 
   
   
       5 . A bag according to claim wherein said bag is filled with said fill material and is closed at said top edge. 
   
   
       6 . A bag according to  claim 5  wherein one of said compartments is filled with a first fill material and a second said compartment is filled with a second fill material. 
   
   
       7 . A bag according to  claim 6  wherein said first fill material is one of soil, dry mix concrete, gravel and sand, and said second fill material is one of dry mix concrete, gravel and sand. 
   
   
       8 . A bag for holding fill material, said bag being for use in the construction of sandbag walls, comprising a bag wall, a closed bottom and a top edge, said bag wall having opposed wall sections attached together along a plurality of lines extending from said bag bottom towards said top edge, forming a plurality of compartments in said bag that are open to said top edge and adapted to receive said fill material therein. 
   
   
       9 . A bag according to  claim 8  wherein there are two said lines of attachment and three said compartments. 
   
   
       10 . A bag according to  claim 1  wherein one of said compartments is larger than the other of said compartments. 
   
   
       11 . A sandbag wall comprising a plurality of courses of bags according to  claim 6  wherein said bags in a course are positioned such that said compartments filled with said first fill material are aligned end to end with each other and said compartments filled with said second fill material are aligned end to end with each other. 
   
   
       12 . A method of constructing a sandbag wall comprising the steps of:
 (a) providing a bag for holding fill material, said bag comprising a bag wall, a closed bottom and a top edge, said bag wall having opposed wall sections attached together along a line extending from said bag bottom towards said top edge, forming two compartments in said bag that are open to said top edge and adapted to receive said fill material therein;   (b) filling a first said compartment with a first fill material;   (c) filling a second said compartment with a second fill material;   (d) closing said bag;   (e) positioning a plurality of said filled bags to form said wall.   
   
   
       13 . A method according to  claim 12  wherein said first compartments of said plurality of filled bags form an outer face of said wall. 
   
   
       14 . A method according to  claim 12  wherein said first fill material is one of soil, dry mix concrete, gravel and sand, and said second fill material is one of dry mix concrete, gravel and sand. 
   
   
       15 . A method according to  claim 14  wherein said first fill material is soil and said first compartments of said plurality of filled bags form an outer face of said wall.
