Sediment control device and system

Abstract

Sediment control devices and systems are provided. The device generally includes a core made up of granular material encased within a puncture resistant fabric, a compressible layer enwrapping the core and a geotextile fabric outer casing. A plurality of such devices provide a system for controlling erosion and sedimentation.

1 . A sediment control device comprising: 
 an inner member structured to be effective in substantially confining a granular material, the inner member including an openable portion for enabling filling of the inner member with such a granular material;    a compressible layer substantially surrounding the inner member; and    an outer member substantially surrounding the compressible layer and including a sealable opening positioned to facilitate access to the inner member openable portion.    
   
   
       2 . The device of  claim 1  wherein the inner member is separable from the outer member.  
   
   
       3 . The device of  claim 1  wherein the outer member opening is substantially aligned with the inner member openable portion.  
   
   
       4 . The device of  claim 1  wherein the outer member sealable opening comprises a hook and loop fastening mechanism.  
   
   
       5 . The device of  claim 1  wherein the inner member openable portion comprises a hook and loop fastening mechanism.  
   
   
       6 . The device of  claim 1  wherein the compressible layer comprises a fibrous material.  
   
   
       7 . The device of  claim 1  wherein the compressible layer comprises fiber layer and a netting layer secured to the fiber layer.  
   
   
       8 . The device of  claim 1  wherein the compressible layer is separable from the outer member.  
   
   
       9 . The device of  claim 1  wherein the inner member comprises a geotextile material.  
   
   
       10 . The device of  claim 1  wherein the inner member comprises a puncture resistant geotextile material.  
   
   
       11 . The device of  claim 6  wherein the outer member comprises a geotextile material.  
   
   
       12 . The device of  claim 1  wherein the compressible layer comprises a material effective for filtering sediment from water passing into the device.  
   
   
       13 . The device of  claim 1  wherein the compressible layer comprises an erosion control blanket.  
   
   
       14 . The device of  claim 1  wherein at least one of the inner member and the outer member is effective to filter sediment from water passing into the device.  
   
   
       15 . A package of sediment control devices, the package containing: 
 a plurality of sediment control device products; and    a shipping container containing the products;    the products being useful for controlling sedimentation when the products are each filled with a granular material, each of the products comprising 
 an inner member structured to be effective in substantially confining a granular material, the inner member including an openable portion for enabling filling thereof with such a granular material,  
 a compressible layer substantially surrounding the inner member, and  
 an outer member substantially surrounding the compressible layer and including an openable, sealable portion positioned to facilitate access to the flexible member openable portion.
