摘要
A three dimensional high strength tightly woven turf reinforcement mat (TRM) or reusable sediment filtration mat designed to trap soil particles in water flow and provide a shear plane to prevent soil wash-out from within and beneath the mat. The mat includes a corrugated body structure integrally extruded or interwoven with a bottom layer that together form a plurality of parabolic sediment entrapment chambers. As sediment bed load moves with water flow into the woven structure, water flow forces sediment through openings in the woven surface of the corrugated body structure and into the chambers where the captured sediment serves as ballast to self-anchor the mat. The mat may also be incorporated during manufacture and/or during/after installation with polyacrylamides, chitosans or other soil flocculating/ aggregating chemicals for increased sediment aggregation and capturing.
