Definitions
- a reinforced embankment structure includes a fill, a siding and reinforcements connected or not to the facing.
- the facing ensures the aesthetics and stability of the structure vis-à-vis erosion by covering the front face of the retaining wall, that is to say the visible face. It is most often made from prefabricated elements juxtaposed concrete, slabs or blocks. It may also consist of metal welded mesh panels or gabions made with braided metal son.
- polyester fibers have the disadvantage of being sensitive to the surrounding alkalinity and can degrade when the stabilizing strips which contain them are used for example in basic soils. This is for example the case of fine soils treated with lime or hydraulic binders to improve their workability and / or stability.
- the functionalized polyolefin advantageously comprises 0.01% to 45% functionalization.
- the functionalized polymeric material advantageously has a functionalization gradient with a maximum in contact with the reinforcing fibers and which decreases as one moves away from the reinforcing fibers.
- the functionalized polyolefin is a polyolefin substituted with a chemical element having a functional group chosen from mono or di-carboxylic acid anhydrides or on which the chemical element has been grafted.
- the chemical element is a maleic anhydride, phthalic anhydride or acrylic acid group.
- shaping of the functionalized polymeric material is effected by coextruding the functionalized polymeric material around the reinforcing fibers and the non-functionalized polymer around the functionalized polymeric material forming the non-functionalized zone of the sheath surrounding or enclosing the functionalized polymeric material.
- PVAL fibers are preferred.
- these materials are not sensitive to the nature of the backfill (and especially to the soil pH used in the backfill composition).
- the reinforcing fibers 12 may also be present in the form of son parallel to each other.
- a "thread" results from spinning the fibers. That is, the fibers are all oriented in the same direction and twisted together.
- a yarn made of fibers is more tensile than all the fibers simply put next to each other, in fact, the spinning strengthens the mechanical properties of the fibers.
- the sheath 11 may comprise at least one longitudinal edge 113 high adhesion free of reinforcing fibers and having notches 114 (see Figures 3 and 4), as described in EP2247797.
- the notches 114 of this longitudinal edge 113 high adhesion function to rub against the embankment of the reinforced embankment work to maintain the stabilizing band 1 in place.
- the stabilizing strip 1 has a length of about 3 m to 10 m, although longer or shorter stabilizing strips 1 may also be provided.
- the width of the stabilizing strip 1 is between 4 cm and 6 cm, although it is possible to manufacture strips of greater width of up to 10 cm or even 25 cm.
- the thickness of the stabilizing strip 1 varies between 1 mm and a few centimeters, but preferably between 1 mm and 6 mm.
- such a reinforced embankment structure 2 also comprises a cladding 22 and connectors 23 for connecting at least a portion of the stabilizing strips 1 to the facing 22.
- the cladding 22 can be made from prefabricated elements 221 and juxtaposed concrete , in the form of slabs or blocks. It may also consist of metal welded mesh panels or gabions made with braided metal son.
- the connectors 23 may be stabilizing strips 1, in particular in the form of loops made by winding and assembling. In this case, the adhesion between the wires and the sheath is essential to ensure the strength of the loop.
- the stabilizing strips 1 comprise a PVAL reinforcement in the form of strands present inside the sheath.
- the PVAL reinforcing fibers are distributed in 5 channels 13 inside the sheath 11 and whose central channel 131 is 7 mm wide and 2 mm high.
- the shape and constitution of the stabilization bands are identical for all the mass ratios PEBDL-f: PEBDL-nf tested and for the control example.
- a cut is made on two opposite side edges of the stabilizing strip, leaving only the central channel 131 intact.
- a transverse incision is made through the central channel 131 over the entire its width, thus cutting the strands in the central channel 131.
- the stabilizing strip 1 is left intact on 10 cm (see Figure 9).
