Definitions

  • the present invention relates to the techniques of building structures in reinforced soil.
  • These structures traditionally comprise a siding, a fill that fills a rear side of the facing, reinforcement elements distributed in the backfill to mechanically stabilize it, and a connection system between the reinforcing elements and the embankment.
  • facings there are different types of facing each having their preferred areas of application.
  • connection of reinforcement strips to concrete is traditionally a source of difficulty. Wherever possible, intermediate connecting parts working in bending or shearing should be dispensed with.
  • One possibility is to provide in the concrete facing element a passage that will follow the request for reinforcement once installed and to anchor the band facing.
  • a solution of this type is described in WO2007 / 102070 . However, this type of solution forces the direction of reinforcement strips immediately behind the siding, which may, in some configurations of the retaining structure, pose difficulties in implementation.
  • connection mode retaining good mechanical properties while offering good flexibility as to the possible configurations of the reinforcing strips.
  • Trellis-type facings are rarely associated with embankment reinforcement elements in the form of flexible synthetic bands.
  • One reason may be that by hanging the bands on the trellis, they are made directly visible on the front of the book, which exposes them to accidental or intentional damage.
  • trellis-type facings are often associated with stony embankments that do not provide an environment conducive to the use of reinforcement based flexible bands. There is also a need to overcome these limitations.
  • a construction structure comprising a cladding, a backfill on a rear side of the cladding, synthetic reinforcement strips distributed in the backfill, and a connection system between the reinforcement strips and the backfill.
  • the connection system comprises continuous closed loop fasteners each having two first clipping portions to the cladding and, alternately with the first portions along the closed loop shape, two second portions extending rearwardly. facing where they are folded to form two loops within which passes at least one reinforcing strip.
  • the use of continuous closed loop fasteners makes it possible to firmly connect the strips to the facing avoiding intermediate parts subjected to shear forces.
  • the continuity of the closed loop limits the risk of losing the connection by deformation of the fasteners due to the large tensile forces that they may suffer from the reinforcement strips because of the backfill load.
  • the topology of the fastener allows it to be put in place in various configurations.
  • a guiding device between on the one hand the two loops formed by the second portions of a fastener and on the other hand the reinforcement strip passing inside these two loops, so that this device works in compression in response to traction exerted by the reinforcing tape.
  • the fastener is metallic and substantially rigid. Such an embodiment is particularly suitable when the facing is in the form of a lattice, the first portions of a fastener then being placed around at least one bar belonging to the lattice.
  • the cladding comprises several elements of lattice, it may be possible to use a fastener to contribute to the assembly of these elements, placing its first portions around at least two bars respectively belonging to two adjacent lattice elements.
  • the embankment of a retaining structure may consist of two layers, one adjacent to the truss facing, made of a material of coarse granulometry, such as pebbles, and the other located in greater depth and made finer material such as earth or sand.
  • the rigid fastener makes it possible to remove from the facing the cusp points of the synthetic reinforcement strips, by making them extend essentially into the layer of finer material, while rigid fasteners extend into the layer. of coarser material to connect the reinforcement strips.
  • the fastener is a flexible belt based on closed loop wound fibers.
  • the guiding device if there is one provided between the two loops formed by the second portions of a fastener and the reinforcement strip passing inside these two loops, may comprise a first curved surface for receiving the reinforcing strip and a second curved surface for receiving the two loops of the second portions of the flexible belt, the first and second surfaces having their respective curvatures in two perpendicular planes. Spacers may be provided to separate the second portions of the flexible belt received on the second curved surface of the guide device to ensure better transmission of forces at the connection.
  • the fastener in the form of a flexible strap is particularly suitable when the facing is made of molded material incorporating, in at least one anchoring region, a passage of flattened section formed between two emergence points located on a rear face of the facing adjacent to the embankment.
  • the first portions of the flexible belt are then placed inside the passage formed in the anchoring region of the facing.
  • the flexibility of the belt allows to orient the reinforcement strips in the embankment without being too constrained by the directions imposed by the passage at its points of emergence of the facing.
  • the passage comprises two portions adjacent to the two emergence points and each arranged to orient parallel to an emergence plane substantially perpendicular to the rear face of the facing an elongated element engaged in said passage, two curved portions. respectively extending the two portions adjacent to the emergence points and arranged to deflect the element out of the emergence plane, and a connecting portion interconnecting the two curved portions and having at least one loop lying outside the plane of emergence.
  • a method of constructing a reinforced soil structure comprising: (i) forming a siding on a front side of the structure; (ii) installing on the facing continuous closed loop fasteners each having two first clipping portions to the cladding and, alternating with the first portions along the closed loop shape, two second portions extending towards the cladding portion; back of the facing where they are folded to form two loops; (iii) connecting synthetic reinforcing strips to the facing, by passing at least one reinforcing strip inside the two loops formed by the second portions of a fastener; and (iv) backfilling a back side of the facing where the reinforcing strips connected to the facing extend with the fasteners.
  • the fasteners When the facing is in the form of a lattice, the fasteners may be substantially rigid and arranged by passing their first portions around at least one bar belonging to the lattice.
  • the fastener may be a flexible belt based on closed-loop coiled fibers.
  • the siding connection of the reinforcing synthetic strips can then include the steps of folding the flexible belt back onto itself and engaging one end of the folded belt in said passage at one of the emergence points, threading the belt folded in the passage until the exit to the other point of emergence of the passage, to balance the belt lengths out of the two emergence points by leaving said first portions in the passage, to join the two ends of the belt opposed to the facing to form the loops of said second portions, and to pass at least one reinforcing strip within the two loops.
  • the figure 1 illustrates the application of the invention to the construction of a retaining wall in reinforced soil.
  • a compacted embankment 1, in which reinforcements 2 are distributed, is delimited on the front side of the structure by a facing 3 which, in the example shown in FIG. figure 1 , is constituted by juxtaposing prefabricated elements 4 in the form of panels, and on the rear side by the ground 5 against which is erected the retaining wall.
  • the reinforcements 2 consist of synthetic reinforcements in the form of flexible strips extending in horizontal planes behind the facing 3. It may in particular be reinforcing strips based on polyethylene fibers wrapped in polyethylene.
  • the reinforcing strips 2 are attached to the prefabricated elements 4 assembled to form the facing 3.
  • These elements 4 are for example reinforced concrete. In the example shown, they are in the form of panels. They could also have other forms, including block.
  • a passage is reserved along a predefined path for a reinforcement strip in order to perform the anchoring strip-element. After being installed along this route, each band has two sections that leave the element to be installed in the embankment.
  • reinforcement strips 2 already installed in the lower levels are stretched. This tensioning results from the friction between the strips and the backfilled material and ensures the reinforcement of the structure.
  • FIG. 2 and 3 illustrate a possible configuration of reinforcement strips at concrete siding, as described in WO 2007/102070 A2 .
  • the two sections of a strip 2 are parallel to an emergence plane P, with no offset perpendicular to the plane P (as shown in FIG. Figures 2 and 3 ) or with such an offset (see international application no. PCT / FR2009 / 052353 ).

  • the rectilinear portions 8 s 'extend over at least half the body thickness of element 4, measured perpendicular to its face 7.
  • Each rectilinear portion 8 of the path of the strip is extended by a respective curved portion 9 where the strip is deflected out of the emergence plane P.
  • the strip 2 extends along the front face of the element, slightly set back from this front face so as not to be visible on the surface of the structure.
  • the two curved portions 9 are interconnected by a connecting portion which has a loop 10 located outside the emergence plane P.
  • the concrete of the element 4 is not poured by having installed the synthetic strip directly in the mold. Instead, a guide piece 15 such as that shown in FIG. figure 4 .
  • This part 15 comprises a rigid plastic sheath whose inner section is of flattened shape to form the passage which will receive a reinforcing strip 4.
  • the sheath is shaped according to the predefined path to be followed by the strip 4 in the thickness of the concrete element. It thus comprises portions 18, 19, 20 which define the rectilinear portions 8, the curved portions 9 and the connecting portion 10 described with reference to FIGS. Figures 2 and 3 .
  • the ends 16 of the sleeve widen to facilitate the introduction of the strip 4. Between these two ends 16, the piece 15 has a tongue 17 projecting from the concrete to stiffen the sleeve and ensure its positioning during the casting of the concrete of the element.
  • a traction member such as a cable, a cord or a strap 12 may be placed inside the sleeve to subsequently set up the reinforcing strip.
  • This flexible belt-shaped fastener 30 is made of closed loop wound fibers, for example polyester fibers of the Same type as those used in reinforcement strips 2.
  • a cladding for example canvas, may be placed around the wick formed by the winding of the fibers.
  • the representation of the figure 5 suggests what will be the configuration of the flexible belt fastener 30 once installed in the structure: two portions 30A are curved and will form two loops engaged together along the path defined by the sleeve 15 in the facing element , while two other portions 30B, which alternate with the portions 30A along the closed-loop shape of the fastener 30, will be used to connect a reinforcing strip 2.
  • the guiding device 40 comprises two guides 32, 33 nested one inside the other.

  • the reinforcing strip 2 comes to bypass the guide 33, following the wings 37 and the curved surface 36.
  • the surfaces 34, 36 have their respective curvatures along two perpendicular planes. They will be positioned so that the plane in which the first guide 32 has its curvature is substantially horizontal, which allows to position the reinforcement strips 2 horizontally in the embankment. Between the curved surfaces 34, 36, the guiding device works in compression, which is a preferred mode of solicitation. Between these two surfaces 34, 36, the two guides 32, 33 can abut one another by means of a flat surface. In a variant, the guiding device 40 may be made as a one-piece piece of the same shape as that formed by joining the two guides 32, 33 previously described.

  • the device 40 is installed in the two loops formed by the portions 30B of the belt, applied against the curved surface of the guide 32. These two loops are made parallel and spaced from each other in the guide device 40 using spacers 38. Then the reinforcing strip 2 is passed inside the two loops 30B by making it follow the curved surface of the other guide 33. It may be possible to use the strap 12 to hold the band 2 in place by tying this strap around the device 40. The band 2 can then be put in tension. Its orientation in a horizontal plane can be chosen as desired by the designer of the structure taking into account the flexibility of the fastener 30.
  • the facing is made of wire mesh 54 and the fastener 80 in the form of continuous closed loop is rigid.
  • the rigid fastener 80 can be made by shaping one or more metal rods and welding the ends to themselves to ensure continuity of the closed-loop shape.
  • the shaping of the fastener gives it two curved portions 80A intended to hang behind one or more metal bars belonging to the lattice 54 and, alternately with the portions 80A along the closed loop shape, two other portions 80B curves for the connection of a reinforcing strip.
  • This connection uses a guiding device which, in the example, comprises a single plate-shaped guide 90 folded so as to have an inner face bearing against the curved portions 80B of the fastener and a curved outer face to receive a reinforcing strip 2.
  • the plate forming the guide 90 works in compression when the connected reinforcing strips are taut at the back of the facing.
  • the rigid fastener 80 is robust and very easy to set up on the mesh-type facing 54. It may possibly contribute to the assembly of adjacent lattice panels 54A, 54B as shown in FIG. figure 10 , being placed around several bars respectively belonging to these panels 54A, 54B.
  • a system of connection strips-siding of the kind of the figure 10 is well adapted to multi-layer embankments, including a first layer against the ground 5 against which the structure is erected and a second layer of relatively coarse material, such as pebbles, placed on the front face of the structure to aesthetic purposes.
  • the first layer, where the strips 2 extend, is made of a finer material than the second layer to avoid damaging the synthetic strips.
  • the fastener 80 makes it possible to prevent the reinforcement strips 2 from being visible on the front face of the structure. In addition, shifting the bands 2 backward improves the fire resistance of the structure because they are less quickly exposed to a rise in temperature in front of the facing.
