Definitions

  • the invention relates to a bottom and bank facing mattress, comprising a mat consisting of a waterpermeable, but sand and soil-tight structure of plastics material, such as a fabric, which is provided with fascine-substitutes.
  • plastics material such as a fabric
  • fascine-substitutes for the fascines of such mattresses, there has hitherto been used willow, osiers or like natural material of more or less irregular shape. The preparation of such fascines and their attachment to the mat is laborious and cumbersome.
  • fascines are dependent on the occurrence of willow, osiers or like wood in nature.
  • this material is increasingly scarcely available.
  • it is subject to rot and other harmful influences, especially when used as a bank facing and similar uses, in which the fascines are located in the wind-and-water line zone. At the coast, this material is liable to damage from shipworm.
  • the known fascines are moreover voluminous and heavy, which renders their shipment and handling difficult. Often the buoyancy of a bottom or bank facing mattress constructed with such fascines is insufficient, because the specific gravity of the wood may be increased to a value in excess of 1 when it has been exposed to water or heavy rain for some time.
  • the object of the invention is to provide a bottom and bank facing mattress of the kind defined in the opening paragraph of this specification, which avoids the above and similar disadvantages of hitherto known constructions.
  • fascine-substitutes each consist of at least one reinforcing tube to be filled with ballast material, said tube being likewise formed of plastics material, such as water-permeable plastics material and/or impermeable plastics foil material, or a bundle of flexible or relatively rigid plastics tubes.
  • the first-mentioned reinforcing elements will be oriented parallel to the bank, so that the required extra firm grip of the fascines on the mat is ensured in a simple manner. This will also effectively prevent the rolling off of ballast rocks during or after sinking of the mat-
  • the plastics reinforcing elements may be formed by striplike portions of the mat proper, such strip portions being of a single layer and being interwoven with each other along their longitudinal edges, the mat being for the rest formed as a double cloth fabric.
  • the hollow portions of the double cloth fabric are located in a grid pattern, and the fields" between them thus consist of a double layer so that they are extremely resistant to the ballast material with which they are to be loaded.
  • a reinforcing element formed of plastics fabric there may be provided an impermeable sleeve of plastics foil, a bundle of thin flexible or relatively rigid plastics tubes, or a second sleeve of plastics fabric.
  • the reinforcing elements are then in fact formed as doublewalled, hollow tubes, or as a bundle of flexible or relatively rigid plastics tubes with an envelope.
  • the reinforcing elements are provided with impermeable linings, or when the elements as a whole consist of an impermeable plastics tube, a number of the elements can be used as floats for the mattress when the tubes are closed at their ends and filled with air during the floating period. When the mattress is sunk, the internal cavities are flooded. [t is also possible to fill the tubes with colloidal, pumpable cement grout, a sand mixture stabilized, for example, with asphalt, or any other ballast material, e.g., plastics. In such cases, the impermeable inner sleeves or the tubular elements are provided with valves.
  • Reinforcing elements of permeable fabric may be filled, for example, with a pressure-resistant foam, e.g., polyurethane foam. It will be understood that this is a permanent filling for a number of elements.
  • the other elements may be filled, during or after the sinking, with a colloidal cement solution, a stabilized sand mixture, or another suitable filling.
  • a quick-drying adhesive may be applied to the crossings of the elements to prevent them from shifting relative to the mat and to each other.
  • Long reinforcing elements can be made by joining the ends of prefabricated lengths together, as by employing connecting sleeves.
  • the construction according to the invention is productive of highly sturdy, relatively rigid mattresses, which can be properly ballasted and are nevertheless sufficiently flexible to adapt themselves to the contours of the bottom or bank.
  • the invention further relates to a method of applying mattresses of the kind described hereinbefore, and to a mattress applied by said method.
  • FIG. 1 is a plan view of a portion of a first embodiment of a mattress according to the invention
  • FIG. 2 is a part-sectional view on the line lI-II in FIG. 1;
  • FIG. 3 is a perspective view of a corner portion of a different embodiment of the mattress construction according to the invention.
  • FIGS. 4a-4d are end views of the synthetic yarn fabric tubular elements of FIGS. I and 2, shown as containing various different materials;
  • FIGS. Sa-Sd are end views of the synthetic yarn fabric tubular elements of FIG. 3, shown as containing various different materials.
  • a mat l of strong polyethylene yarn woven so as to be waterpermeable, but sand and soil-tight, and having a tensile strength of at least 2 ton/m.
  • Woven into the mat are bands 5 of abt. 30 threads of the same or similar yarn of a color contrasting with that of the mat, said bands being spaced axial distances of 50 cm apart, and having floating or nomwoven portions 4 of abt. 20 25 cm every 2 m.
  • impermeable tubes 3 of PVC or polyethylene having an external diameter of abt.
  • tubular elements 3' formed of synthetic yarn fabric such as polyethylene, and the tubular elements are received; under the series of loops 4 thus formed, thereby to form reinforcing elements extending in the longitudinal direction of the mat.
  • tubular elements 2' are inserted as transverse reinforcing elements under the longitudinal elements 3, 3 intermediate each two corresponding pairs of loops 4. to be likewise spaced axial distances of abt. 2 m apart.
  • the transverse elements 2 can be tied to the loops 4 which are grouped in pairs along each band of threads 5.
  • the ends of the reinforcing tubes 2 and 3 are closed with plastics caps 7, so that the air-filled tubes form floats.
  • the fabric of the mat Adjacent the ends of the inserted elements 2 and 3, the fabric of the mat is connected with the elements by means of rope 6 inserted through the last loops 4' of the bands 5.
  • the caps 7 are removed. By injecting colloidal cement grout into the internal cavities of the tubes 2 and 3, the mattress can be ballasted.
  • the mattress 11 as shown in FIG. 3 consists generally of a mat 12 of double cloth fabric with single-layer fabric portions l3, l3 and 14, 14, arranged in pairs and extending at right angles to each other in the desired grid pattern of the reinforcing elements. Along their edges, these portions pass into the double cloth fabric, which forms the fields between the reinforcing elements.
  • sleeves l5 and 16 of impermeable plastics foil Inserted into the communicating cavities thus formed, are sleeves l5 and 16 of impermeable plastics foil. which cross each other at the nodes of the grid.
  • the sleeves of plastics foil can be filled with ballast material in one direction. In the case of a mattress for use in bank revetments, this should be the direction parallel to the bank.
  • the plastics foil in the other direction can be temporarily inflated and closed to serve as floats.
  • FIGS. 4a 4d show one of the separate tubular elements 2' or 3' of FIGS. 1 and 2, where the tubular element 2' in FIG. 4a is filled with a ballast material 18', the element 2' of FIG. 4b has a plastic tube 2 received therein; the element 2' in FIG. 4c has a plastic tube 2received therein, said tube being filled with a ballast material 18', and, FIG. 4d has a bundle of plastic tubes 19 received therein.
  • FIGS. Sa-Sb show the tubular elements of synthetic yarn fabric as formed in the modification of FIG. 3, wherein the single layer portions which are not interwoven define the grid of elements 2" and 3".
  • FIG. 5a shows an element 2" filled with ballast material 18
  • FIG. 5b shows an empty plastic tube 2 received in the element 2
  • FIG. 5c shows a tube 2 received in the element 2" and filled with a ballast material 18
  • FIG. 5d shows an element 2" having a bundle of plastic tubes 19 received therein.
  • a mattress for the protection of soil surfaces comprising a water-permeable, but sand and silt-tight synthetic yarn fabric in the form of a relatively large continuous mat, a plurality of elongated tubular elements arranged in a grid form, and means connecting said elements to said mat, wherein each said elongated element is formed by a tube of synthetic yarn fabric.
  • a mattress according to claim 1 wherein the synthetic yarn fabric of the mat is a double cloth, and, wherein the tubular elements of the grid are formed between the single layers of the double cloth, said layers being interwoven at spaced areas to form a plurality of squares spaced apart by said tubular elements.
  • a mattress according to claim 1 further comprising a plurality of plastic tubes received respectively in the interior of the respective synthetic fabric elements of the grid.
  • a mattress for the protection of soil surfaces according to claim 3, wherein at least selected ones of said plastic tubes are filled with ballast.
