Definitions
- the present invention relates to the construction of structures in reinforced soil or reinforced earth. This construction technique is commonly used to make structures such as retaining walls, bridge abutments, etc.
- a reinforced soil structure combines compacted backfill, siding and reinforcement usually connected to the facing. Reinforcements are placed in the soil with a density depending on the constraints that can be exerted on the structure, the thrust forces of the ground being taken up by the friction soil-reinforcements.
- the invention is more particularly concerned with the case where the reinforcements are in the form of strips of synthetic material, for example based on polyester fibers.
- the facing is most often made from prefabricated concrete elements in the form of slabs or blocks, juxtaposed to cover the front face of the structure. There can be horizontal recesses on this front face between different levels of the facing, when the structure has one or more terraces.
- Reinforcements placed in the embankment are usually joined to the facing by means of mechanical connection members that can take various forms. Once the work is completed, reinforcements distributed in the embankment transmit high loads, up to several tons. Their connection to the facing must be robust to maintain the cohesion of the whole.
- the facing elements are shaped to have at least one passageway for receiving a reinforcing strip.
- Document EP 1 662 050 describes a structure in reinforced soil, comprising a backfill, reinforcing strips extending in a reinforced area of the embankment located at the rear of a front face of the structure, and a facing placed on the along said front face, the reinforcing strips being anchored to the facing in respective anchoring regions.
- the cladding incorporates a path formed for a reinforcement strip between two emergence points located on a rear face of the facing adjacent to the embankment.
- This path comprises two rectilinear portions respectively adjacent to the two emergence points and each arranged to position the strip in the same emergence plane perpendicular to said rear face, two curved portions respectively extending the two rectilinear portions and arranged to deflect the strip off. the emergence plane, and a connecting portion interconnecting the two curved portions and having at least one loop located outside the emergence plane. It also describes a facing element adapted to such a work.
- such a structure is generally constructed by arranging at least one facing adapted along a front face of the structure delimiting a volume to be backfilled and by performing the following successive steps:
- a trench is hollowed in an area of the laying surface, corresponding for example to an area where it is expected to have the end of the reinforcing strips;
- a reinforcing strip is provided which follows said path in the facing member so that the two portions of strips emerging therefrom rest on the strip surface and in at least a part of the trench; the strip is tensioned by adding backfill material to the strip so as to at least fill the trench.
- the excavation step to dig a trench lengthens the duration of the construction and requires the use of labor.
- the object of the present invention is to propose a new method of anchoring reinforcement strips to a facing of a structure on reinforced soil which makes it possible to reduce the incidence of the above problems.
- the invention proposes a structure in reinforced soil, comprising a backfill, reinforcement strips extending in a reinforced area of the embankment located at the rear of a front face of the structure, and a facing placed along said front face, the reinforcing strips being anchored to the facing in respective anchoring regions, wherein the facing incorporates, in at least one anchoring region, a path formed for a reinforcement strip between two emergence points located on a rear face of the facing adjacent to the embankment, where the path comprises two adjacent portions respectively adjacent to the two emergence points and arranged to position the strip each in an emergence plane substantially perpendicular to said rear face, two curved portions respectively extending the two adjacent portions and disposed to deflect the strip out of the emergence planes, and a connecting portion connecting them curved portions characterized in that the two emergence planes are distinct, separated by a physical separator and substantially parallel to each other to form an upper and lower emergence plane and in that the connecting portion comprises at least one loop located outside of the emergence plans and out of the space between these
- the invention further provides a reinforced soil structure, comprising a backfill, reinforcement strips extending into a reinforced area of the embankment located at the rear of a front face of the structure, and a facing placed along of said front face, the reinforcing strips being anchored to the facing in respective anchoring regions, wherein the facing incorporates, in at least one anchoring region, a path formed for a web reinforcement between two emergence points located on a rear face of the face adjacent to the embankment, where the path comprises two adjacent portions respectively adjacent to the two emergence points and arranged to position the band each in an emergence plane substantially perpendicular to said rear face, two curved portions respectively extending the two adjacent portions and arranged to deflect the band out of the emergence planes, and a connecting portion interconnecting the two curved portions where the two emergence planes are distinct and substantially parallel between them to form an upper and lower emergence plane and wherein the connecting portion comprises at least one loop located outside the emergence planes and out of the space between these emergence planes.
- the embankment thus pushes the portion of the strip emerging from the upper plane towards that emerging from the lower plane, effectively ensuring a tensioning portions of the strip.
- a plane of emergence substantially perpendicular to a face, a plane whose angle relative to a plane perpendicular to the tangent plane of said face in the emergence zone is less than or equal to 25 °, for example less than or equal to 10 °, in particular equal to ⁇ °.
- the angle between these two emergence planes may be an angle measured relative to the plane perpendicular to the tangent plane of the face of the facing in the emergence zone in a direction perpendicular and / or parallel to said tangent plane.
- the term "physical separator” means a portion of material disposed in the anchoring region and adapted to separate the two emergence planes.
- the physical separator may be in continuity of material in the anchoring region of the facing. It may also consist of an insert in the siding anchoring region.
- the adjacent portions are rectilinear portions.

- the band may be set up along the path as soon as the body material is molded, with or without the aforementioned protective sheath.
- the two curved portions of the path direct the band towards the same side of the emergence planes. It is considered that the curved portions of the path direct the band towards the upper side, respectively the lower side, if these portions each is oriented above, respectively below, each of the emergence planes.
- a first possibility is that the path is formed so that the band is received in the two adjacent portions with the same face of the band oriented towards this side of the emergence planes. The path is then formed so that said face of the strip is placed either on the outer side or on the inner side of the loop located outside the emergence planes.
- a second possibility is that the path is formed so that the band is received in one of the two adjacent portions with one face of the band facing said side of the emergence planes and in the other of the two rectilinear portions with said face of the strip facing away from said side of the emergence planes.
- the two curved portions of the path respectively direct the strip towards two opposite sides, one above and one below the emergence planes

- FIGS. 5 to 9 are perspective views of paths that reinforcement strips may follow in facing elements according to the invention.
- Figure 1 illustrates the application of the invention to the construction of a retaining wall 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 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.
- 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 typically made of reinforced concrete. In the example shown, they are in the form of panels. They could also have other forms, including block.
- one or more reinforcement strips 2 are installed in the mold along a path described later in order to to perform the band-element anchoring. After taking the concrete, each band has two sections that leave the element to be installed in the embankment.
- the mounting and positioning of the facing elements can be facilitated by connecting members placed between them.
- the strips 2 are positioned on the facing elements 4 so that some of them are placed at the same horizontal level during the assembly of the facing; b) providing backfill material and progressively compacting it to the next planned level for placing reinforcement strips 2; c) spread the reinforcement strips 2 on the embankment at this level; d) provide backfill material over the reinforcement strips 2 that have just been installed.

- a reinforcing strip 2 is placed in the mold when casting the concrete and maintained until the setting of the concrete. Its guidance can be achieved using the reinforcing bars of the concrete (not shown), possibly supplemented by rods or deflection members attached to these bars, so that the band follows the desired path in the anchoring zone. This path is defined inside the element 4 between the two emergence points PE1, PE2 of the two sections of the strip on the rear face 7 of the element (face adjacent to the backfill).
- the physical separator 41 in continuity of material, allows the shift between the two emergence planes.
- FIG. 5 The path corresponding to the element of FIG. 4 is illustrated in FIG. 5. It has two adjacent portions, here rectilinear 21 and 22 extending perpendicular to the rear face 7 of the element from the emergence points PE1. and PE2. In each adjacent portion 21, 22, the band remains in each of separate emergence planes P1, P2. Portions rectilinear 21, 22 extend over at least half the thickness of the body of the element 4, measured perpendicularly to its rear face 7. This avoids improper solicitation of the concrete in the vicinity of the rear face 7.
- Each rectilinear portion 21, 22 of the path of the strip is extended by a respective curved portion 23, 24 where the strip is deflected out of each of the emergence planes P1, P2.
- 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 strip is directed towards the same side P12, P22 of the emergence planes P1, P2 in the two curved portions 23, 24 of its path within the facing element 4.
- This path is formed so that (i) in the two rectilinear portions 21, 22, the strip has the same face oriented towards the sides P12, P22 of the emergence planes, and (ii) this face of the strip is placed on the outer side of the loop 25. Accordingly, in the middle of the loop 25, the band is placed substantially perpendicular to the rear face 7 of the element.
- the loop 25 ' is oriented in the opposite direction, that is to say that the face of the strip oriented towards the sides P12, P22 of the emergence plane is placed on the inner side of the loop 25 '.
- the band comprises a loop
- FIG. 8 shows an example in which the connecting portion interconnecting the two curved portions 31, 32 comprises two loops 30 on either side of the planes P1, P2.
- the two curved portions 31, 32 of the path respectively direct the band towards the two opposite sides P1 1, P21 and P12, P22 of the emergence planes P1, P2.
- the connecting portion has a portion 33 which passes through the planes P1, P2 and interconnects the two loops 30.
- the emergence points PE1, PE2 are offset from each other, and when a strip is installed in a structure, the two slots situated on the rear face of the facing and from which emerges the band are shifted so as not to meet the same vertical plane.
- the emergence points PE1, PE2 are not offset from each other, and when a strip is installed in a structure, the slots situated on the rear face of the facing and from which they emerge the band meet the same vertical plane.
- This figure illustrates such an embodiment where the path is of the type illustrated in FIG. 5 and where the two rectilinear portions 21 and 22 are located one behind the other.
- the width of the strip 2 is less than or equal to at least half the thickness of the facing element 4. This thickness is typically between 14 and 16 cm. It will then be possible to use strips approximately 45 mm wide.
- the reinforcing strip has components (eg polyester fibers) sensitive to basic environments, it may be advantageous to place between this strip and the concrete facing a plastic protective sheath.
- This sleeve prevents the alkalinity of concrete from spreading to the sensitive component.
- the flexible sheath receives the band before being put in place with it in the mold. He is thus surrounded by the molded concrete and receives the reinforcing tape along its path to isolate it from the concrete.
- the slots corresponding to the emergence points PE1, PE2 for the same strip are situated in distinct vertical planes, so that a space, for example between 2 and 5 cm , separates the vertical planes PV1 and PV2 separating the emergence points closest to the same band.
- the physical separator 41 in continuity of material, allows the shift between the two emergence planes.
- the two slots corresponding to the emergence points PE1, PE2 are situated between two same vertical planes and meet the same vertical plane PV3.
- the physical separator 42 in continuity of material, allows the shift between the two emergence planes.
- FIGS. 10 and 11 require an operation of threading the strips along their paths. But it provides the advantage of providing the ability to choose the strip length regardless of the manufacture of the facing element.
- the proposed method of connection between the facing of a reinforced soil structure and at least some of its reinforcement strips is compatible with a large number of structural configurations, strip lengths, setting up bands, etc.
