Definitions

  • the invention relates to an erosion prevention sheet material, and to products produced therefrom, for use in preventing, or at least alleviating, erosion, particularly in coastal, maritime, land and riverine shores, artificial reefs, dams, lakes, tailings storage facilities and the like.
  • a further problem is encountered at the seam lines of geo-containers.
  • the yarn that is used in stitching the seams of the geo-cpntainers during manufacture is exposed to and abraded over time by the natural elements, which results in failure of the geo-containers.
  • the applicant has identified a need for an improved erosion prevention sheet material which is lighter in weight than conventional bi-layered sheet material, but with improved inter-layered peel strength.
  • the applicant has also identified a need to protect the seams of geo-containers or the like bags, which are produced from such sheet material, against the abrasive conditions in which these products are used.
  • Geo-container - a bag which is designed and manufactured from high-strength fabrics, called geotextiles, which is typically filled with gravel, soil, sand, recycled material, treated material or a combination thereof, and which is used for stabilising banks and slopes, and for controlling erosion and/or pollution of soil so as to protect coastal, maritime, land and riverine shores, artificial reefs, dams, lakes, tailings storage facilities and the like from erosion caused by environmental factors.
  • Geo-containers also find application in de-watering industrial and contaminated sludges generated by various industries, polluted waterways, ponds, dams and stilling basins.
  • Figure 3 is one embodiment of a geo-container according to the invention, illustrating the sewn seam edge
  • Figure 4 is an enlarged sectional end view of the sewn seam edge of the geo-container of
  • Figure 5 is a side elevation of the sewn seam edge of Figure 4.
  • the reinforcement layer [14] may include high tenacity, low elongation filament yarns for maintaining the form of the laminated sheet material [10] and products produced therefrom.
  • the high tenacity, low elongation filament yarns may be derived from glass fibre, synthetic or natural continuous filaments, spun filaments, grids and/or scrims.
  • the grids and/or scrims may be derived from knitting, CrenetteTM, woven and/or extruded origin. More particularly, the grids and/or scrims may be manufactured either from cotton, flax filament yarns and the like natural filament yarns, or from synthetic filament yarns.
  • Figures 1 and 2 depict a woven or knitted layer with a warp [17] and a weft [19].
  • the reinforcement layer [14] further may include non-woven fleece fabric [23].
  • the non-woven fleece fabric [23] may be manufactured from natural fibres, synthetic fibres or a combination thereof.
  • the non-woven fleece fabric [23] may be manufactured from polyethylene terephthalate and/or other polymer materials.
  • the laminated sheet material [10] may have a cross-sectional thickness range of 5mm to 100mm and a mass range of 50g/m 2 to 5000g/m 2 .
  • a method of manufacturing a laminated sheet material [10] suitable for use in minimizing erosion and/or pollution of soil comprising the steps of - providing an entrapment layer [12] for trapping gravel, soil, sand or the like particles; providing a filtration layer [16] for allowing through-filtration of water and other moisture through the laminated sheet material [10]; providing a reinforcement layer [14] between the entrapment and filtration layers [12, 16] for reinforcing the laminated sheet material [10] and increasing inter-layer peel strength between the entrapment and filtration layers [12, 16]; and
  • the laminated sheet material [10] of the invention may be shaped and dimensioned to be used as a ground cover, wrap-around envelope sheet and/or a geo-container.
  • the invention extends to a ground cover, wrap-around envelope sheet and a geo-container produced from the laminated sheet material [10] of the invention for preventing, or at least alleviating, erosion, particularly in coastal, maritime, land and riverine shores, artificial reefs, dams, lakes, tailings storage facilities and the like.
  • a method of manufacturing a geo- container [24] for use in minimising erosion, particularly in coastal, maritime, land and riverine shores, artificial reefs, dams, lakes, tailings storage facilities and the like comprising the steps of - providing a laminated sheet material [10] including an entrapment layer [12] for trapping gravel, soil, sand or the like particles, and a filtration layer [16] for allowing through-filtration of water and other moisture through the laminated sheet material [10];
  • the laminated sheet material [10] may be sewn with a high strength polymeric yarn, including polyester, polypropylene, polyethylene and other synthetic yarns.

Abstract

L'invention concerne un matériau stratifié en forme de feuille (10) et un géoconteneur (24) produit à partir de celui-ci et conçu pour être mis en œuvre dans la prévention ou au moins l'atténuation de l'érosion, en particulier dans les espaces littoraux et les rivages maritimes et fluviaux, les récifs artificiels, les barrages, les lacs les installations de digues à rejets et similaires. Ledit matériau stratifié en forme de feuille (10) est caractérisé en ce qu'il comprend au moins trois couches, à savoir : une couche de piégeage (12) destinée à piéger le gravier, la terre, le sable ou des particules similaires; une couche filtrante (16) permettant le filtrage de l'eau et autres traces d'humidité à travers le matériau stratifié en feuille (10); et une couche de renforcement (14) disposée entre la couche de piégeage et la couche filtrante (12, 16) pour renforcer le matériau stratifié en forme de feuille (10), accroître la résistance au pelage entre la couche de piégeage (12, 16) et réduire l'allongement du matériau stratifié en forme de feuille (10). Le matériau stratifié en forme de feuille (10) comprend en outre des moyens de liaison [21] pour lier les couches de matériau les unes aux autres.
