Definitions

  • the invention relates to a method and a device for anchoring the scales of a reinforced earth wall.
  • Some reinforced earth walls are made up of unreinforced concrete scales on their outside facing which hold the ground by means of metal reinforcements embedded in the ground, and moored to the scales. Certain walls thus constructed are threatened with ruin due to the oxidation of the frames embedded in the ground.
  • the subject of the invention is a method and a device making it possible to effectively repair such walls and to avoid their ruin.
  • the scales are anchored by means of support plates which retain them and which are properly anchored to the ground.
  • the first plates used had a square shape, then a four-pointed star, as we can see, by reading the provisional document of SETRA, dated November 9, 1987 and entitled: "Reinforcement of reinforced earth structures with stainless steel frames".
  • the branches of these stars are suitably ribbed and directed each substantially 90 ° from the next.
  • the central zone of these stars is pierced with a hole which allows the passage of the head of a tie rod and the support of the tightening nut.
  • the star support plane comprises, on the side of the star support plane, a projecting crown and, on the opposite side, a hub, which constitutes, with the crown, a central sleeve.
  • the invention also relates to a device allowing the implementation of the above-mentioned method, and more specifically to a support plate having the general shape of a star with four suitably ribbed branches, each directed substantially at 90 ° from the next, and from a central area.
  • This zone is pierced with a hole for the passage of the head of a tie rod and for the support of a tightening nut which fixes the plate to the tie rod.
  • the central zone of the support plate comprises, on the side of the support plane of said plate, a projecting crown, and, on the opposite side, a hub which constitutes, with the crown, a central sleeve, as known from SETRA document mentioned above.
  • FIG. 1 there is illustrated in longitudinal section, at the level of the head of a tie rod, the positioning of a support plate making it possible to retain a scale of unreinforced concrete from the facing of the wall. in an armed land threatened with ruin.
  • the terrain is referenced and in 11, a scale of the facing which is of substantially rectangular shape with recesses facilitating the staggered laying of these scales, as it appears more clearly in FIG. 2.
  • FIG. 1 it can be seen that, in the unreinforced concrete scale 11, a hole 12 has been drilled substantially in the center of the scale, as also identified in FIG. 2.
  • the hole 12 has been made at an angle determined by calculation, suitably inclined to the horizontal as it appears more clearly in figure 3.
  • the drilling was done, through the scale and over a calculated length, in the ground. This length depends on the nature of the ground and the height of the embankment to be maintained.
  • the length of the tie rod, at the level of the median scale 11 was of the order of 5 meters.
  • a tie and drill length of 4 meters may be sufficient, while at the underlying level 11 ', the calculation will indicate a tie length of 6 meters for example.
  • the tie rod has been identified, which may be constituted by a steel bar comprising, at its head 14, a thread for placing a tightening nut over a support washer 16 and a gasket 17 (for example, made of Shore hardness rubber 80) holding the support plate 18 which comes to bear, by its pads 19, on the outer surface of the scale 11.
  • a gasket 17 for example, made of Shore hardness rubber 80
  • the support plate 18 has, on its internal face turned towards the terrain, a sort of crown 20 towards the rear and a hub 41 towards the front forming a central sleeve, the whole inclined along an axis 42 on the horizontal and therefore, at an angle to the general support plane of the plate 18.
  • a tube 21 made of suitable plastic such as PVC is engaged.
  • another section of plastic tube of similar quality 22 comprising a truncated cone 22a uniting a part of reduced diameter 22b which encloses the tube 21 and a part 22c of enlarged diameter fitting, with a certain clearance, inside the borehole 12.
  • this section 22c of enlarged diameter is also received a third section of tube 23 of similar quality.
  • the total length of the three sections engaged end to end 21, 22, 23 is chosen so as to correspond substantially to the thickness of the scale 21.
  • These sections can be joined together, for example, by gluing or heat sealing, and the tube 21 can be fixed, for example, by gluing to the crown 20.
  • the support plate 18 is in the form of a star with 4 ribbed branches, marked 34 to 37, oriented at 90 ° from each other, and positioned on each scale such that 11, so that the support pads 19, located at the ends of each branch, are on the diagonals 38, 39 of the scales, at a certain distance from their center 40, where the orifice 12 was drilled the passage of the tie.
  • the scales such as 11 were of a substantially square shape 1.50 m on a side, while the 4-pointed star 18 was inscribed substantially inside a 40 cm square side, a distance from pad 19 to pad 19, opposite on the same diagonal, of the order of 50cm.
  • the plate 18 is made of cast iron, as well as the pads 19 which are part of this plate.
  • the abovementioned support plates make it possible to limit, to precise regions of the unreinforced concrete flakes 11, the rigid support contacts, which allows the abovementioned scales to withstand, in much better conditions, the forces brought by the anchors.
