Definitions

  • the invention relates to the rehabilitation of a soil consisting of a solid and healthy substrate, a screed in hardened hydraulic mortar made on the substrate and a wear coating adhering to the screed, the screed has excessive porosity which reduces or limits the mechanical properties of the soil.
  • a new use of the land consists of example to allow a floor originally designed for a pedestrian use to be operated as part of a industrial use.
  • micropiles from 100 to 150 mm in diameter approximately.
  • the pins are distributed so that the micropiles are substantially contiguous.
  • the anchors are also used to temporarily maintain the coating so to prevent it from lifting during the injections, possibly until the bonding or sealing, which makes it possible to implement a high injection pressure, favorable to distribution of the product in the voids of the yoke.
  • a pressure in the range 2-5 bars should be sufficient for this purpose, at least in the generality of the cases, without excluding more pressures high if necessary, for example up to 20 bars.
  • the invention also relates to a device for rehabilitate a soil consisting of a substrate, a hydraulic mortar screed made on the substrate and which has voids and a wear coating adhering to the screed by gluing or sealing, which includes a set of micropiles made up of tubular and hollow steel dowels which pass through vertically the screed and are anchored in the substrate and a bonding product which has been injected under pressure in the ankles, diffused in the voids of the yoke around the ankles by lateral perforations of the ankles and hardened, thus constituting micropiles armed by ankles.
  • the invention also relates to the ankles.
  • pegs are made, for example, by removable tubes and end pieces, for example screwed or clipped to the tubes, these end pieces carrying flanges capable of maintaining the coating when the ankle is in place.
  • the pin shown in Figure 1 includes a hollow steel metal tube (1), with a diameter of 6 to 8mm, and a ferrule (2). Both parts can be fixed temporarily to each other, for example by screwing.
  • the tube (1) has lateral holes (3) and has a lower end (1A) provided with slots (4).
  • the tube has a thread (6) at its upper end.
  • the end piece (2) is capable of being screwed onto the thread (6) of the tube and has a transverse flange (7).
  • the number and distribution of boreholes to be drilled and corresponding pegs, as well as the volume of injection by drilling are chosen according to the case of application and the volumes of vacuum to be filled, determined in advance, so that the product injected in an anchor is spread in the screed at least in an area (Z) of 100 to 150mm in diameter around the ankle, across the entire height of the yoke. Of preferably, these zones (Z) are almost contiguous, as this is shown diagrammatically in FIG. 7.
  • a simple method consists, for example, in taking a carrot in the screed mortar, steaming and hydrate it, weighing the carrot after steaming before hydration, and weighing it after hydration.
  • the boreholes are divided into so that in any direction on the covering, any ankle is at most 35cm, preferably at most 30cm, even better at most 20cm, if necessary, from another ankle.
  • the number of pegs increases with the volume of the screed void. For example, 30, 40 or 50 dowels per m 2 are used depending on whether the porosity of the screed is greater than 20%, 30% or 40% of the volume of the hardened screed. It goes without saying that these values are given for information only.
  • drilling are preferably made in the joints between the slabs, for example due to drilling near each slab angle.
  • Drilling can also be carried out in slabs themselves, especially if the covering must be subsequently hidden or changed.
  • a faulty floor or for pedestrian use having an operating load limited to 300 kg / m 2 can support loads equal to or greater than 8000 kg / m 2 and equal or greater than 4000 kg per wheel. handling equipment.
  • Sealing the ankles in the solid and healthy substrate provides the unit with inertia and tensile strength capable of resuming hydrostatic thrusts of more than 5000 kg / m 2 .
  • the invention is not limited to the embodiments which have been described and applies to any type of coating, continuous or discontinuous, and to any substrate, with or without an intermediate screed, the covering as the substrate being, vertical, horizontal or other, plane or not plan.
