Definitions

  • the invention relates to a process for coating and / or supporting the walls of natural or artificial excavations such as embankments, banks, trenches, wells, tunnels, etc., according to which anchoring reinforcements are sealed in the floor and covering and / or retaining elements are hung on the sealed reinforcement.
  • Such a method relates, in particular, to the protection, reinforcement, or stabilization of land.
  • the object of the invention is, above all, to provide a method of coating and / or supporting excavation walls which meets better than hitherto the various requirements of the practice and which, in particular, makes it possible to obtain with a minimum of coating operations. It is further desirable that such a process leads to a coating having good soundproofing and sealing qualities and which is aesthetic.
  • a method of coating and / or supporting excavation walls is characterized in that the coating elements are prefabricated elements which comprise, on their edges, connecting means with the adjacent elements, which these covering elements are assembled "in situ", that there are, over the entire height of the excavation wall, drainage means between this excavation wall and the covering, and finally we put in place a packing behind the assembled prefabricated elements.
  • the prefabricated elements are essentially full, that is to say that the total area of the openings possibly formed in these elements is less than 30% of the total area of the element.
  • the number of prefabricated elements fixed to reinforcements sealed in the ground (and therefore the number of reinforcements sealed in the ground) can be at most equal to half the number of prefabricated elements.
  • the number of sealing reinforcements, and therefore the number of prefabricated elements fixed to these reinforcements is equal to one third of the total number of prefabricated elements.
  • the jam may consist of a lean mortar or a swelling product.
  • the prefabricated elements can be identical; they can be placed alternately on the front and back.
  • connection means between the prefabricated elements can be constituted either by assembly means of the "dry” type such as grooves or notches male and female conjugate, or by assembly means involving a sealant of the mortar type, resin or other, the edges of the prefabricated elements being provided with grooves intended to receive the sealant.
  • the blocking of the prefabricated elements on the frameworks sealed in the ground is generally carried out after the injection of the tamping.
  • the invention also relates to prefabricated cladding and / or support elements, in particular for the implementation of a process as defined above, these prefabricated elements being characterized in that, preferably, they are essentially solid, (that is to say that the surface of any openings they can comprise is less than 30% of the total surface of the prefabricated element), and that they comprise, on their edges, means of connection with adjacent elements.
  • the prefabricated elements intended to be fixed to sealing reinforcements, may include a reinforced zone provided with a hole for passage of the sealing reinforcement, this reinforced zone being provided in particular in the central region of said element.
  • the prefabricated elements can have a hexagonal or circular shape. They can be made of concrete, binders or composite materials.
  • Anchoring frames 2 are sealed in the ground S and protrude from the wall 1, by parts 3 provided at their outer ends s with fastening elements such as a thread capable of cooperating with an appropriate nut Q.
  • the frames 2 are driven into the ground S with a percussion / vibration machine (not shown); alternatively, a hole can be drilled in the ground, and the reinforcement is introduced into this hole.
  • the frame can be sealed in the ground, which remains in place, with a cement grout or similar product.
  • Covering elements 4 are hung on the sealed frames 2.
  • covering elements 4 are constituted by prefabricated elements which are essentially solid, that is to say that if openings are provided inside the contour of each element 4, the surface of the openings is less than 30% of the total surface of element 4.
  • each opening has an area less than 1/20 of the total surface of element 4.
  • element 4 can have an area of the order of one square meter.
  • the elements 4 have, on their edges, connecting means L with adjacent elements.
  • the elements 4 can be flat or curved, for example partially cylindrical.
  • the edges 5 of the elements have, at mid-thickness, a recess 6 so that an edge 7 having a thickness substantially equal to half the thickness of the element, extends beyond the entire outline of the element.
  • the projecting edges 7 will come to bear against each other as shown in FIG. 10, which will ensure a connection of the elements or panels with each other.
  • connecting means L of the "dry” type may have shapes different from those shown in FIGS. 1 and 10.
  • protruding elements such as 8 could be provided.
  • FIG. 8 in the form of a "dovetail” intended to cooperate with corresponding recesses such as 9.
  • Figure 9 shows another variant of connecting means which can be provided on the edge of the elements 4, and which is constituted by a sort of tongue 10 of circular shape, which is connected by a portion 11 narrowed at the edge of the panel.
  • This tongue 10 is intended to cooperate with a corresponding recess, in the manner of the connecting means provided between the pieces of a puzzle.
  • the part 7a projecting over the entire periphery of the covering element is limited by a convex-concave surface 12 suitable for cooperating with the convex-concave surface. of the adjacent element arranged upside down.
  • FIG. 12 represents connection means L of the tenon type 13 provided on the edge of an element and mortise 14 provided on the edge of the adjacent element.
  • the connecting means L involve a keying by sealant M, of the mortar, resin or other type, between the elements 4a, 4h which have, on their edges, grooves or grooves g, X intended to receive this sealant.
  • sealant M of the mortar, resin or other type
  • a strong inclusion such as steel bars, fibers, or the like can be provided in the sealant.
  • the covering elements 4 or 4a, 4b are assembled “in situ” and are fixed to the end parts 3 of the sealed frames.
  • the elements 4, 4a, 4b are put in place as the excavation E progresses. As visible from FIG. 1, the elements 4, 4a, 4b are put in place top to bottom.
  • the assembled system is self-stable.
  • the number of elements 4 that are fixed on the reinforcements 2 and therefore the number of sealed reinforcements 2 is at most equal to half of the total number of prefabricated elements.
  • Drainage means D are arranged over the entire height of the excavation wall 1, between this wall 1 and the covering R.
  • These drainage means D may be constituted, for example, by a draining curtain such as a sheet 16 of fibers, in particular a geotextile sheet unwound along the wall 1.
  • a channel 17 provided with a drain 18 is provided at the bottom of this wall to collect drainage water.
  • the drainage means D can be constituted by strainers (not shown) formed by plastic pipes provided with holes in their wall and arranged against the wall 1 while being inclined downwards.
  • a stuffing B is injected.
  • This stuffing can be formed by a thin mortar or by a swelling product, or even by sand.
  • the stuffing B is put in place using holes existing in the elements (either anchoring holes or specific stuffing holes).
  • Figures 15 and 16 show anchoring devices with a head in particular self-locking between adjacent elements.
  • the edges 7 of the adjacent elements 4 are inclined substantially at 60 * - 70 * relative to the mean plane of the element.
  • the frame 2 passes between two adjacent edges.
  • a self-blocking head T made of resistant material (metal, concrete, hard plastic), in the shape of a trunk of a pyramid or a truncated cone, whose wall matches that of the edges, acts like a wedge under the action of the anchoring force, this head T being retained by the nut d.
  • the head T1 is formed by a sort of plate with projecting edges u engaged in the notches provided on the adjacent elements, with possibly self-locking effect.
  • the frames 2 can be provided with an adjustable internal stop w (for example plate metal) ( Figures 15, 16), allowing correct positioning of the prefabricated elements.
  • an adjustable internal stop w for example plate metal
  • the elements such as 15 (FIG. 6) intended to be fixed to the sealing reinforcements 2 comprise a reinforced zone 20, of greater thickness, in particular provided in the central region of said element and provided with a through hole for the frame 2.
  • the prefabricated elements 4 can be identical or complementary.
  • the coating R involves different coating elements.
  • elements 21 in the form of regular octagons fixed on the frames 2.
  • the spaces 24 delimited by a contour formed by elements 21 and elements 22, 23 can be open or, possibly, provided with other elements or with own means to retain stuffing B, in the case where the space 24 has a large surface.
  • FIG. 4 shows a variant according to which the elements 21 of octagonal shape, anchored on the frames 2, ensure the maintenance of other elements 26 of square shape of which one diagonal is substantially vertical and the other diagonal substantially horizontal.
  • These prefabricated elements, of two different types, are coupled to each other in a determined order.
  • FIG. 5 shows a coating obtained using identical elements 27 substantially of square shape but whose angles have been cut.
  • An element 27, fixed on a frame 2 is arranged "front” while other elements 27 &, adjacent to this element 27 are arranged “back” (in a manner similar to that shown in FIG. 1) to allow the attachment of the connecting means L, of the type shown in FIGS. 10 and 11, provided on the edges of these elements.
  • FIG. 7 shows an embodiment in which the prefabricated elements 28 have a circular shape.
  • One element in three, as in the case of FIG. 6, is fixed on a connecting frame 2, the distribution of the fixed elements among all the other elements being regular, as in the case of FIG. 6.
  • the method of the invention allows a rapid coating of natural or artificial excavation walls, having interesting properties on the phonic level, in particular because of the nature of the surface, and on the aesthetic level.
  • FIG. 17 shows a variant in which longitudinal elements 4f (vertical, horizontal, oblique) are fixed at several points, on several anchors 2, these longitudinal elements 4f serving to maintain transverse elements 4g ensuring the coating.
