Definitions

  • the present invention relates to a stabilizing reinforcement for use in reinforced soil structures, as well as the use of such a reinforcement for the construction of structures in reinforced soil.
  • a reinforced soil structure combines a compacted embankment, a siding and reinforcements connected or not to the facing.
  • the facing is for example made from prefabricated concrete elements, in the form of slabs or blocks, juxtaposed to cover the front face of the structure.
  • a book thus produced is known in particular under the commercial reference Terra Class of Terre Armée Internationale.
  • the facing may also be made from a grid, in particular consisting of metal rods welded together.
  • a siding may comprise a geotextile and may be vegetated.
  • a book thus produced is known in particular under the commercial reference Terra Trel of Terre Armée Internationale.
  • reinforcements may be used: metal, for example comprising rods of galvanized steel, of synthetic material such as stabilizing strips for example based on polyester fibers.
  • the reinforcements are placed in the ground with a density depending on the stresses that may be exerted on the structure, the thrust forces of the ground being taken up by the friction soil-reinforcements.
  • the stabilizing reinforcements are attached to the facing and / or to a wall located at a distance from the facing.
  • Stabilizing reinforcements for use in reinforced soil structures include longitudinal, elongated portions. Their length is of the order of magnitude of the meter. They can reach several meters in length.
  • the longitudinal portions of the reinforcements may be arranged one by one in the ground, or may be assembled together by different means. The width and the thickness of such longitudinal parts are of the order of a centimeter, and generally do not exceed ten centimeters.
  • the longitudinal portions may be arranged substantially perpendicularly to the facing or be arranged at an angle to the facing. In the latter case, there are generally longitudinal portions on either side of an axis perpendicular to the facing. In general, the longitudinal portions of the reinforcements are arranged in a substantially horizontal plane.
  • An example where the longitudinal parts are at an angle to the facing is the modular reinforcement arranged in a triangular network according to FR-A-2233857 . This document represents the prior art closest to the reinforcement of claim 1.
  • Metal stabilizing reinforcements are often considered advantageous in terms of price and generally consist of metal rods welded together to form for example ladders or trellis.
  • a ladder-shaped reinforcement generally consists of two substantially parallel metal rods, each constituting a longitudinal portion, and transverse rods which connect the longitudinal rods together to provide rigidity to the assembly.
  • transverse is meant a portion of a reinforcement that connects two longitudinal portions to each other. Such parts are for example made of rods. As a result, the transverse portions are arranged to be substantially parallel or angled with respect to a facing.
  • transverse rods of the ladder-shaped reinforcements are generally arranged perpendicularly to the longitudinal rods. They may, however, be inclined relative to the longitudinal rods.
  • transverse rods are generally distributed over the entire length of the longitudinal rods and in particular spaced regularly.
  • the spacing between two transverse rods is of the order of a few tens of centimeters for a usual ladder-shaped reinforcement.
  • one end of the ladder-shaped reinforcement comprises a fastening means to the facing, in particular hooks formed or arranged on one end of the longitudinal rods, or a flat and pierced piece connecting the ends of two longitudinal rods, where the pierced portion of said part is intended to receive means of connection with the facing.
  • the metal rods used for such reinforcements are generally steel rods. They are often cylindrical and their diameter is generally of the order of a centimeter. These rods are advantageous to use because their cost is very moderate. However, the medium in which they are disposed is corrosive, especially because of the pH of the soils and ions they include, which may further vary with time, rainfall or other parameters.
  • Such ladder-shaped stabilizing reinforcement has several disadvantages. It is often necessary to move it, or even to transport it from a remote production site, before setting it up on a soil reinforcement site. The associated transportation costs can be high because such reinforcements are bulky.
  • welds are sometimes weak points of a ladder-shaped reinforcement. It seems indeed that protection by galvanizing is often imperfect in the weld zones, thus potentially allowing localized corrosion and significantly reducing the robustness of the whole.
  • One solution may be to increase the safety coefficients for a given structure, for example by increasing the density of reinforcements. Such a solution is nevertheless expensive and unsatisfactory.
  • An object of the present invention is to overcome the aforementioned drawbacks and in particular to provide a reinforcement free of risks associated with corrosion of welds between longitudinal and transverse parts.
  • the invention thus proposes a stabilizing reinforcement defined precisely in claim 1.
  • transverse moving parts transverse parts may be displaced relative to at least one longitudinal portion. This displacement may correspond to a translation, in which case the transverse part moves as a whole with respect to the two longitudinal parts. This displacement can also be a rotation. In some cases of rotation, a point, in particular an end of a transverse part may remain fixed relative to a longitudinal portion, while the remainder of this transverse portion moves relative to the two longitudinal portions. It is also possible to combine a translation and a rotation.
  • the displacement of a transverse portion relative to a longitudinal portion may be effected from the zone of the reinforcement where the two longitudinal portions are farthest from each other to the zone where these longitudinal portions are the closest, especially to the point where the axes of these two longitudinal portions overlap, that is to say in the direction of the interior of the embankment to the facing when the reinforcement is disposed in a structure.
  • angular stops to limit the angular spacing of two longitudinal portions any means for limiting the angular spacing of the two longitudinal portions, in particular by limiting a distance between two points of two separate longitudinal parts.
  • a stabilization reinforcement according to the invention it is possible to avoid welding the longitudinal parts to the transverse parts. As a result, such a reinforcement no longer presents a risk of preferential corrosion.
  • the combination of a non-zero angular difference ⁇ + ⁇ between two longitudinal portions and the use of transverse portions comprising angular stops makes it possible to ensure the stiffening of the reinforcement when said longitudinal parts come into contact with said abutments of the transverse parts.
  • the invention also relates to a structure in reinforced soil comprising a facing along a front face of the structure and / or a wall delimiting a backfill, wherein said backfill is stabilized by at least one stabilizing reinforcement according to the present invention.
  • the invention also relates to such a reinforced soil structure where the angles ⁇ and ⁇ are substantially equal to each other, the angles ⁇ and ⁇ each measuring the angular difference between an orthogonal axis facing and one of the two longitudinal portions.
  • the structure thus produced is preferably obtained with a plurality of said stabilizing reinforcements, each comprising two longitudinal parts, where these different reinforcements are spaced from each other, without them touching or being interconnected by something else. only fill material.
  • these various reinforcements are connected to the siding at intervals regular, both in a horizontal plane and in a plane parallel to the facing. In this way, a reinforced structure is obtained efficiently and easily.
