Definitions

  • the present invention relates to a lightweight protection element and filter of the mattress type, and in particular, though in a non-limiting manner, to a ballasted filtering mattress for protecting and covering terrain, more preferably a seabed.
  • Another limitation of the elements of known type is constituted by their limited overall dimensions, which are linked to the dimensions of the gabions and/or the forms which are used for constructing them.
  • An object of the present invention is to provide a protection element and filter of the mattress type which has significantly reduced weight, which allows easier installation, which has overall dimensions which are variable in accordance with the type of application necessary and which can successfully constitute protection elements and a filter without longitudinal discontinuities, for example, but in a non-limiting manner, up to 200 linear metres.
  • Another object of the present invention is to provide a protection element and filter which is economical, easy and rapid to construct and which therefore allows a substantial saving in terms of the time and cost of installation.
  • the present invention relates to a lightweight protection element and filter of the mattress type as defined in the main claim below.
  • the protection element further comprises a three-dimensional internal structure with a high cavity index, in which filler material is inserted, such as gravel, silt, finely crushed stone, or any other natural granular element which is available in situ. That advantageous feature avoids the need to create internal diaphragm openings for stabilizing the filler material.
  • the mattress type element also comprises a double layer of geotextile material, for example, an upper layer and a lower layer, which, being connected to the three-dimensional internal structure, allow the protection element to act as a filtering element and, at the same time, to remain fitted closely against the terrain to which it is applied owing to the ballast weight of the granular filler material.
  • a double layer of geotextile material for example, an upper layer and a lower layer, which, being connected to the three-dimensional internal structure, allow the protection element to act as a filtering element and, at the same time, to remain fitted closely against the terrain to which it is applied owing to the ballast weight of the granular filler material.
  • FIG. 1 is a schematic perspective view of a lightweight protection element and filter of the mattress type according to the present invention.
  • FIG. 2 is a schematic sectioned view along line A′-A′ of the element illustrated in FIG. 1 .
  • a lightweight protection element and filter of the mattress type comprises an external containment structure.
  • the external containment structure comprises a lower portion, for example, a bottom sheet 10 , and an upper portion, for example, a cover sheet 20 .
  • Both the sheets 10 and 20 can be constructed from synthetic material, preferably geosynthetic material, for example, woven geotextiles or woven geogrilles, geomembranes, geonets.
  • the sheets 10 and 20 can be constructed from natural material, preferably a biomat and/or a biodegradable bionet, for example, of straw, coconut fibre or wood shavings, and generally natural fibres.
  • a reinforcement element 48 for example, a metal net and/or a geogrille, can be engaged with the bottom sheet 10 so as to increase the resistance to traction of the whole mattress.
  • a three-dimensional internal structure 30 with a high cavity index preferably a non-woven goetextile, even more preferably a three-dimensional structure comprising monofilaments of heat-sensitive material, for example, synthetic polymers and/or polyamides.
  • the monofilaments of heat-sensitive material can be extruded onto the reinforcing metal net and/or geogrille 48 .
  • Granular filler material for example, gravel, sand, silt, finely crushed stone or any other natural element which is preferably available in situ, is inserted inside the three-dimensional internal structure 30 with a high cavity index.
  • the granular filler material serves as an auxiliary in the filtering action of the three-dimensional draining structure 30 , to maintain the thickness of the three-dimensional geosynthetic even under great loads and to weigh down the whole lightweight protection element and filter.
  • the bottom sheet 10 and the cover sheet 20 are engaged with each other by way of engagement means, preferably of the mechanical type, for example, but in a non-limiting manner, a pair of plates 50 , or continuous strips, constructed from synthetic and/or metal materials.
  • the plates 50 are arranged, in an aligned, opposing state, on the external surfaces of the bottom sheet 10 and the cover sheet 20 and distributed over the surfaces in the region of respective openings formed in the surfaces of the two sheets 10 and 20 .
  • Each plate 50 comprises a through-hole, inside which there is passed a fixing bar 52 with a thread 54 , scarfed in the plate 50 or lower strip.
  • Two blocks 56 are screwed to the ends 54 of the bar 52 so as to secure the position of the two plates 50 along the bar 52 and to engage the bottom sheet 10 and the cover sheet 20 with each other.
  • the engagement means are distributed uniformly over the entire extent of the bottom sheet 10 and cover sheet 20 so as to bring about through-fastening of the protection element and filter.
  • the ends of the sheets 10 and 20 are fixed to each other, for example, by means of continuous seams 53 so as to close the protection element and filter and retain inside it the three-dimensional structure with a high cavity index and the filler material.
  • the external containment structure of the protection element and filter comprises, for example, but in a non-limiting manner, a pouch or a container of synthetic or natural material, as described above, which is open at one side and inside which there is inserted the three-dimensional structure with a high cavity index and the filler material.
  • the open ends of the external structure are fixed to each other, for example, by means of continuous seams 53 so as to close the protection element and filter and retain inside it the three-dimensional internal structure and the filler material.
  • the filler material may comprise fertile soil, seeds and/or other similar material, should the sheets 10 and 20 have been constructed from geosynthetic materials of natural fibres.
  • the lightweight protection element and filter can thereby be used for covering terrain, embankments and inclinations which have to be renewed.
  • the embodiments of the invention may change in accordance with the various dimensions and pieces of equipment of the finished mattresses.
  • finished mattresses of great linear extent, generally over from 6 to 7 metres in length
  • pontoons or rollers on which the elements roll whilst for single shorter mattresses there can be used lifting frames of various forms and dimensions.
  • the fixing bars 52 can be provided with engagement means, for example, end ring bolts, so as to be able to allow them to be connected to the lifting frame during the installation operations.
