Definitions

  • the present invention relates generally to building, shoring, drainage and flood control structures and, in particular, to these structures having at least one side covered with synthetic turf.
  • gabions As described in U.S. Patent No. 5,472,297 , certain structures are known by the name “gabions” and comprise essentially wire mesh cages having a block shape, which are filled with rock, stone, rubble and the like. Although such gabions are made up of wire mesh cages filled with stone and other rubble, in effect they often function like solid blocks which can be used for building, for shorings for hillsides, for sea walls and the like, for walls and for other purposes.
  • U.S. Patent No. 5,472,297 also describes that such gabions can be filled with a much looser particulate as compared to being filled with rock. That patent describes that the filling material can be sand, concrete, ash, soil colliery waste and small particular aggregate. The patent also describes that to use the loose particulate material, the interior of at least some of the gabion is lined with flexible sheet material, and the cage is filled with a particulate of a nature which, but for the lining, would pass through the meshes of the cage.
  • the present invention relates to earthwork basket-like structures utilizing synthetic turf to improve weatherability (longevity in spite of being exposed to wind, rain, and sun) and to improve the visual aesthetics.
  • These earthwork baskets are typically made of wire or mesh cage or a basket and have common industry names of gabion, gabion mattress, gabion basket, reno mattress, or concentainer.
  • These earthwork baskets are typically used for applications involving flood control, flood barriers, retaining walls, walls and barriers, drainage channels, grade control, erosion control, shoreline and coastal protection, and slope reinforcement.
  • the present invention comprises an earthwork basket including a multi-sided wire or mesh cage or basket which optionally can be erected from a flat, folded configuration to an erect, fillable configuration.
  • the earthwork basket also includes a liner for lining at least part of the multi-sided cage.
  • the liner is made from a synthetic turf comprising a backing and a plurality of synthetic grass blades tufted into and extending from the backing.
  • the backing is comprised of one or more geotextile(s), which optionally may be coated to increase tuft bind.
  • the synthetic turf is placed along at least one side of the multi-sided cage. In example embodiments, the synthetic turf is placed along one side or face of the cage, while in other embodiments the synthetic turf is placed along multiple sides or faces of the cage.
  • the earthwork basket can take various shapes, such as cylindrical, cubic, brick, block, triangular, oval, L-shaped, V-shaped, etc.
  • the multi-sided cage has 2 sides. In a preferred form, the multi-sided cage has 6 sides.
  • the synthetic turf faces outwardly from the multi-sided cage and optionally the synthetic turf is positioned along multiple sides of the multi-sided cage.
  • the synthetic turf is installed on the inside face(s) of the multi-sided cage and optionally the synthetic turf is installed on the outside face(s) of the multi-sided cage.
  • one or more sides of the multi-sided cage can be lined with a geotextile and/or sheet film liner.
  • the synthetic turf need not be used on every face or side of the cage, although it can be so used if desired.
  • the present invention relates to a bundle of earthwork basket-like blocks including a plurality of earthwork basket-like blocks mechanically fastened to one another to form a bundle.
  • Each earthwork basket-like block has a wire or mesh cage or basket structure optionally erectable from a folded configuration to an erect fillable configuration and a liner for containing loose fill material within the earthwork basket-like block.
  • the liner includes a synthetic turf positioned along at least one portion of the earthwork basket-like block, with the synthetic turf including a synthetic backing and a plurality of synthetic blades tufted to and extending from the synthetic backing.
  • the synthetic turf is oriented in the earthwork basket-like block so that the synthetic blades extend and face outwardly from the earthwork basket-like block.
  • the present invention relates to earthwork basket constructions for preventing erosion on flood control structures, channels, and slopes; for providing reinforcement to walls and slopes; and for creating a barrier.
  • Figures 1-2 show an earthwork basket 10 according to a first example embodiment of the present invention.
  • the earthwork basket 10 generally includes a multi-sided wire or mesh cage or basket 20 and a liner 30 for lining at least a part of the basket 20.
  • the liner 30 is placed on one face of the basket 20.
  • the liner 30 is made from a synthetic turf comprising a backing and a plurality of synthetic grass blades tufted into and extending from the backing.
  • Patent Application No. 2012/0064262 and U.S. Patent Application No. 2012/0064263 show examples of synthetic turf and are incorporated by reference herein in their entirety.
  • the backing of the liner 30 comprises one or more geotextile(s), which may be coated to increase tuft bind.
  • the earthwork basket 10 is filled with rock, gravel, soil materials, sand, shredded tires, ash, soil colliery waste, small particular aggregate, other loose material, or cementitious material.
  • the earthwork basket is filled with soil.

  • the earthwork basket 10 has a first face comprising the liner 30 (e.g., synthetic turf) and a second face (generally opposite the first face) comprising the secondary liner 40.
  • the secondary liner 40 can be in the form of a geotextile and/or sheet film liner that is preferably UV resistant and substantially durable.
  • the secondary liner 40 can be provided in addition to the liner 30 or can be omitted.
  • the basket 20 can be constructed from steel, galvanized steel, zinc-coated steel, stainless steel, PVC-coated steel, aluminum, fiberglass, or polymeric material. Generally, the basket 20 has junctions that are welded, fused, single twisted, double twisted, or woven together. In typical forms, the basket is double twisted or welded together.
  • the earthwork basket 10 can take various shapes, such as cylindrical, cubic, brick, block, triangular, oval, L-shaped, V-shaped, and various other shapes as desired.
  • the basket 20 can be erected from a flat, folded configuration to an erect, fillable configuration.
  • the synthetic turf is affixed to the one or more faces of the basket 20 by heat bonding, adhesive bonding, stitching or sewing, mechanical fasteners, or combinations thereof.
  • the earthwork basket 10 is modular and is capable of being stacked on top of another earthwork basket 10.
  • the earthwork basket 10 can be placed side-by-side or butted end-to-end with one or more additional earthwork baskets 10.
  • FIG 3 shows an earthwork basket 100 according to another example embodiment of the present invention.
