Abstract
Described herein is a protected container employed to prevent soil erosion. The protected container is a geotextile container having a debris shield disposed thereon. The debris shield protects the integrity of the geotextile container by providing a strike barrier which has air and water flow capabilities. The debris shield is a composite fabric comprising a woven protective layer having abrasion resistance and a woven three-dimensional layer which provides impact dampening and energy dissipation.
Claims41
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric, and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising a plurality of intertwined tubular structures and having no more than about a 10% compression at a load of 20 pounds/inch2.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric, and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising a plurality of intertwined tubular structures and having no more than about a 10% compression at a load of 32 pounds/inch and an air flow of at least 700 cubic feet/minute.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising a plurality of intertwined tubular structures and having no more than about a 10% compression at a load of 32 pounds/inch, a water flow between about 20 gallons per minute/foot2 and about 350 gallons per minute/foot2, and an air flow of at least 750 cubic feet/minute.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric and another layer comprising a three-dimensional, plain 4-layer tubular weave fabric having an air flow of at least 750 cubic feet/minute, the debris shield having an impact resistance of at least 105 feet/second as measured in accordance with American Society for Testing and Materials International (ASTM International) Standards E1886-05 and E1996-12.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric, and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising polypropylene yarn and polyethylene yarn and having no more than about a 10% compression at a load of 20 pounds/inch2.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric, and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising at least one shrink yarn and at least one non-shrink yarn and having no more than about a 10% compression at a load of 20 pounds/inch2.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric, and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising non-shrink yarns having a size in a range between about 8 mils and about 30 mils and having no more than about a 10% compression at a load of 20 pounds/inch2.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric, and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising 20 mil, round polypropylene yarn and 315 denier, round low density polyethylene monofilament and having no more than about a 10% compression at a load of 20 pounds/inch2.
A debris shield comprising at least two layers, one layer being an abrasion resistant woven fabric, and another layer comprising a single-weave three-dimensional, plain 4-layer tubular weave fabric comprising a thickness of about 500 mils and having no more than about a 10% compression at a load of 20 pounds/inch2.
