Benefits of technology

[0004]These wall-building units, which hold more fill material than a conventional sandbag, are used in place of sandbags in the construction of retaining walls and erosion control structures.
[0005]In this specification, “fill material” means any material that is suitable for use in bags in the construction of walls, including sand, soil, gravel, dry mix concrete (which hardens after wetting and curing) and mixtures thereof, including fill material with seeds for vegetation. The term “sand-bag” as used in this specification means a bag containing any “fill material.” For further clarity, the term is not limited to a bag in which the fill material is sand. The term “wall” as used herein in relation to structures made of wall-building units includes any array of wall-building units that is suitable for the purpose of erosion control (for example along shorelines, riverbanks, etc.), flood control, retaining or stabilizing slopes or embankments, noise barriers, landscaping, and for similar applications.

Problems solved by technology

In a conventional sandbag, the bag fill volume is limited by the fact that the top edge of the bag must be gathered together and tied in order to close the bag.

Embodiment Construction

[0011]The invention provides wall-building units comprising a combination of two bags. A prior art sandbag containing fill material is shown in FIG. 1. Prior art bag 100 has sewn bottom edge 102 and a side edge 104. It is tied closed at top edge 106 by means of a tie 108. In order to be able to fill the bag, the top edge is pulled together in a cinched configuration, as a result of which the bag cannot be filled to its top edge. The shoulders 110 reflect the reduction in fill volume resulting from this closing requirement.

[0012]In wall-building unit 120, shown in FIGS. 2 and 4, this loss in fill volume is eliminated. Inner bag 122 has a bag wall 124, a closed bottom 126 and an open top edge 128. The bag wall 124 is sewn closed along longitudinal edge 130. Outer bag 132 is of equivalent structure, with a bag wall 134 sewn along longitudinal edge 136, and a closed bottom 138 and an open top edge 140. The outer bag is positioned to extend longitudinally over the inner bag 122 so that i...

Abstract

A wall-building unit for use in the construction of sandbag-type walls for erosion control, slope stabilization and similar applications comprises an inner bag filled with a fill material and an outer bag extending longitudinally over it so that the bottom of the outer bag is adjacent to and covers the open top edge of the inner bag. The wall-building unit holds more fill material than a conventional sandbag.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention pertains to sandbag wall systems for use in erosion control, flood protection, coastal protection, slope stabilization and similar applications.BACKGROUND OF THE INVENTION[0002]In the art of erosion control, flood protection, coastal protection, slope stabilization and the like, it is known to build stable and effective walls of sandbags, preferably using interconnecting plates to connect the bags together and stabilize the wall. See, for example, international patent publication WO 00 / 61880 (Kim), dated Oct. 19, 2000. The sandbags used in such systems have hitherto been conventional in design. In a conventional sandbag, the bag fill volume is limited by the fact that the top edge of the bag must be gathered together and tied in order to close the bag. It would be desirable to provide a sandbag configuration in which the bags could be filled to their top edge, thus holding more fill material.SUMMARY OF THE INVENTION[0003]The invent...
