Definitions

  • the present invention relates to the technical field of construction in the general sense, that is to say including the realization of buildings or works, as well as earthworks, roads, etc ...
  • level backfilling in the case of buried constructions executed from an open excavation, in the case of the construction of a parking area or a traffic lane established on sites of different levels or, again, in the case of construction of a raised load-bearing base which must have characteristics of good mechanical, sound, thermal and / or acoustic insulation with respect to a level slab of a building.
  • Such materials also induce forces and thrusts on structures in contact with or near massifs and, mainly, on structure abutments, supports, etc.
  • an acceptable proposition consists in using, for the production of a body of solid mass, materials of low density, such as, in particular, of expanded polystyrene.
  • the density of this material is, in fact, generally between 20 and 40 kg / m3, which represents a significant gain compared to traditional backfill materials.
  • This technique which has been the subject of a number of previous publications, such as FR-1 398 975, AT-352 639, US-A-4 080 793 and FR-2 380 375, consists in disposing, in superimposed layers or in vertical piles, used or rejected tires which, in most cases, are linked together by links or anchoring means.
  • the cells, delimited by the tires and / or between the tires are then filled with backfill materials which are thus immobilized.
  • Such a technique therefore aims, mainly, the immobilization of retaining masses, but does not make it possible to significantly reduce the density of the latter. It is therefore a technique which is not suitable for achieving the objective of the present invention which is that of making it possible to produce a light mass to reduce the stresses applied, either to the underlying layers or to the benches supporting them, either, again, to the underlying or surrounding constructions.
  • the present invention proposes, precisely, a new process for the construction of a lean and flexible massif, responding exactly to the objective sought, by enabling it to be produced at a cost significantly lower than that of all the proposals which have been made in the same technical area.
  • Another object of the invention is to propose a new process for producing a lighter mass making it possible to use materials which, ordinarily, constitute waste which is difficult or not recyclable.
  • Another objective of the invention is to propose a new process for constituting a lighter mass offering, in addition, additional new properties, such as flexibility, sound, thermal and acoustic insulation, damping, even localized hygrometric balance (by water retention).
  • the method according to the invention is characterized in that it consists in: - constitute the solid mass by means of tires devoid of permanent effective mutual connection and of filling material to form an alveolar body of low density, - associate the body thus formed with an immobilization and anchoring layer.
  • the invention also relates to a lighter solid mass obtained by implementing the above method.
  • Figs. 1 and 2 illustrate an example of implementation of the object of the invention in the case of the construction of a parking or circulation area raised above ground S whose nature or composition gives it character compressible. So as to be able to execute an embankment on such a soil allowing the parking or circulation area to be placed at the required level, the method according to the invention consists, first of all, in producing an upright seating surface î and, in the present case, adjusted.
  • This surface 1 can be formed directly by the ground S or, alternatively, by a drainage base 2 constituted in any suitable manner in the art and, in particular, by a layer of clean sandy sand.
  • the lightened solid 3 is then covered with a layer 5, such as a sheet or sheet of woven or non-woven material.
  • layer 5 can consist of a sheet of a material, such as that frequently used in the construction field to facilitate upwelling while ensuring containment and retention of materials.
  • the sheet 5 can be constituted, for example, by a sheet of material sold under the name "BIDIM U 44".
  • the layer 5 is designed to assume a function of immobilization and anchoring of the mass 3 to maintain a sort of cohesion or volume confinement of the tires 4 which are simply relatively stacked, without involving any links or fasteners between them.
  • the surface of the ply 5 is calculated so as to leave, on either side of at least two opposite sides of the solid mass 3, two overhanging lateral bands 6 whose function appears in this following.
  • Fig. 1 shows that it can also be provided, for the same purpose, to place, at intermediate levels of the height of the bed 3, sheets 5 a of a material identical or similar to that of the web 5 and comprising at least one lateral strip 6 has overflowing. This may be the case, in particular, in the horizontal plane of each tiered level, as shown in FIG. 1.
  • the light mass 3 is thus in the form of a honeycomb volume, constituted by discarded tires piled up or stacked, and which is isolated by the surface 1 and the ply (s) 5.
  • Another phase of the process then consists in making, at least along the sides corresponding to the presence of the strips 6 and 6 a , lateral support embankments 7 raised from the surface 1 to the plane of the upper ply 5.
  • the lateral retaining embankments 7 are formed in the form of natural slopes, from traditional embankment materials.
  • Another phase of the process consists in covering the layer 5 as well as the upper surfaces of the lateral retaining embankments with a layer 8 of load distribution, for example in a semi-crushed material.
  • the last phase of the process consists in associating, with the load distribution layer 8, either a reinforced concrete slab 9 representing the surface of wear, parking or circulation, or a flexible bituminous pavement.
  • the embankment according to the invention can then be finished by adding a layer of topsoil 11 along the natural slopes of the lateral support embankments 7.
  • the method described above can, of course, be implemented in a substantially analogous manner for the execution or construction of a platform and in such a case, the layer 5, 5a, the side retaining embankments 7 and topsoil layers 11 are then provided on the whole perimeter defining such an area, such perimeter is defined by a continuous, curved periphery or, on the contrary, by rectilinear sides.
  • an embankment 5 m thick (including pavement) will lead to a ground stress four times smaller than that of an embankment which would have been formed, constituted or erected from traditional backfill materials.
  • Such a light backfill has, moreover, the advantage of being able to be built quickly and at a very attractive cost, due to the low, or even non-existent, market value of the tires 4.
  • Another advantage of the process is that its use implemented provides a solution to the general pollution problem posed by the accumulation of discarded tires.
  • Fig. 3 shows an alternative embodiment according to which the light weight 3 consists of stacks or stacks of tires 4 placed in rows and in alignment, as opposed to the staggered geometric arrangement illustrated in FIG. 2.
  • the tires 4 could just as easily be chosen of any size and stacked in an all-purpose presentation to constitute piles, even irregular ones, the final stability of which is ensured by the layer 5 and by the lateral support embankments 7.
  • each ply 5 can be associated with a lattice 1 metallic or not, constituting a tension reinforcement.
  • the trellis 12 can be placed under or on the sheet 5 or 5 a and have overhanging lateral areas similar to the strips 6, 6 a . These areas are intended to be embedded in the lateral support embankments and may, as the case may be, be bent downwards or not.
  • Fig. 5 schematically shows another example of application of the object of the invention in the case of making a buried structure, for example constituted by a tunnel T constructed from an open excavation 14.
  • the excavation 14 is, usually after construction, filled according to the prior art with an embankment material whose mass volume exerts a significant compression stress on the roof 15 of the tunnel T.
  • the excavation 14 is, at least in part, filled by lateral embankments of support 16 which are, substantially, raised up near the ridge of the vault 15.
  • the method of the invention consists then to raise, simultaneously, the lateral support embankments 16 and to constitute, in abutment on the external surface 17 of the arch representing the seat surface 1, a light mass 3 by stacking tires 4 arranged, either in bulk or in stacks, either in superimposed beds or layers matching the seating surface 17.
  • the block 3 is, as before, made stable by the presence of at least one layer 5 covering the stack of tires 4, so as to leave two overhanging side strips 6 which are embedded in the upper mass of the side fill materials support 16.
  • a load distribution layer 8 which can also, if necessary, be associated with a slab 9 or pavement 10 similar to the previous example.
  • the method of the invention makes it possible to constitute, above the vault 15, a lightweight backfill body with a significantly reduced density compared to that of traditional backfilling materials. It thus becomes possible to reduce, in large proportions, the compression stresses exerted on the roof 15 and to reduce the mechanical strength characteristics leading to a reduction in the cost of the construction of the tunnel T as a whole.
  • the cohesion of the lightened solid mass 3 is ensured by the layer or layers 5, 5 a thus, possibly, only by the trellis or trellis 12 and also by the presence of embankments lateral 7 or 16.
  • the solid mass 3 can be devoid of lateral embankments or associated with embankments incapable of assuming the transverse blocking function which is partly assigned to them.
  • the cohesion of the block 3 can then be obtained by ensuring the stacking of the tires 4 on a sheet or ply previously placed on the sole 2. This sheet or ply has an area greater than that which must be occupied by the block 3, so that its lateral edges can be raised along the periphery of the massif. In association with the layer (s) 5, 5 a , it thus becomes possible to form an envelope surrounding the block 3 and ensuring the overall cohesion of the tires 4.
  • Fig. 6 is a voluntarily schematic elevation of another example of application of the method of the invention. In this example, it is a question of producing a load-bearing sole 18 which has to be isolated from the structure, itself load-bearing of a building and, for example, of a level slab 19.
  • the slab 19 is produced to form, at least locally, the seat surface 1 according to a horizontal level lower than its general upper surface.
  • the slab 19 thus has, locally, a sort of pit 20 which is occupied, at least in part, by a lightened solid mass 3 constituted as said previously.
  • the block 3 it is preferable to give the block 3 a height less than the depth of the pit 20, so as to be able to fit, at least in part, the base 21 of the sole 18 carried by the block 3 and then also constituting the load distribution layer and, simultaneously, the surface of use.
  • an immobilization layer 5 in the form of a sheet or envelope, as said previously.
  • the layer 5 can also include overhanging bands which can be anchored in the lateral mass of the slab 19 when the latter is formed from the seating surface 1 after the formation of the light mass 3. It can also be provided to have a distribution layer 8 independent over layer 5, possibly associated with a trellis or a reinforcing reinforcement.
  • the method of the invention makes it possible, taking into account the nature of the tires 4, to produce a solid mass 3 having, in addition to its low density associated with high mechanical strength, certain characteristics of thermal and sound insulation, shock absorption, flexibility, vibration filtration and can thus be implemented to achieve, at low cost, a massif 3, each time at least one of the above objectives must be achieved (sports floors, floors, protection of structures against falling blocks, pavements and parking lots ).
