Definitions

  • the present invention relates to a flexible support device for the walls of underground galleries.
  • metallic reinforcements are preferably used.
  • the latter can be carried out by a specific bolting in which one proceeds to a local treatment of the bad grounds met, and which applies to a good number of underground exploitations.
  • This punctual bolting consists of the installation in dangerous places of a reinforcement constituted by one or more anchor rods called bolts, which, introduced into the thickness of the wall, and fixed by means of plates and nuts against this, securing doubtful areas to areas considered healthy.
  • wedge expansion shell
  • resin cement
  • the metal reinforcements can also be produced by systematic bolting.
  • the reinforcement consists of a set of anchor rods placed at regular intervals according to a grid and a depth defined by the operator to systematically treat the whole of a gallery or a district. gallery, and this to promote the formation of an artificial supporting vault.
  • the density of this bolting must be sufficient to resist the thrusts of the ground. It is sometimes necessary to complete this support with the installation of wire mesh or gunite to remove the risks represented by the chipping of the rock between the anchor rods. This process has the same drawback as that reported in the occasional bolting, namely that no information is perceived by the operator in the event of local pressure on the ground.
  • the metal reinforcements can finally be produced by means of metal frames.
  • These frames then form a kind of gantry formed by two lateral bridges which serve to transmit to the ground, the forces resulting from the thrust of the ground being exerted on the upper hanger. They are placed at a certain distance from each other depending on the nature of the terrain crossed and are interconnected by longitudinal assembly bars.
  • This device consists of a set of reinforcements laid p er- right angles to the axis of the tunnel and spaced from each other, and characterized in that each reinforcement is made of iron plate whose shape conforms to the geometry of the wall and comprises an upper element pierced in the middle with an oblong hole and longitudinal grooves, and at least two lateral elements placed on either side of the upper element assembled together by overlap and also pierced with grooves, rods anchor threaded either in the hole or in the grooves, one end of which penetrates the wall and the other threaded end of which enables the said elements to be pressed against the wall by means of a support plate and a tightening bolt suitable for threading.
  • the device according to the invention does it consist of a set of frames each composed of flat iron elements, assembled together by overlap.
  • Each frame includes several elements.
  • a superior element the first to be installed and which therefore interests the vault of the gallery to be consolidated.
  • This flat iron carries at the top of its radius of curvature, a small oblong hole, through which is threaded an anchor rod in a hole previously drilled at the head of the gallery.
  • This anchor rod like all anchor rods, consists of a head which penetrates into the wall of the gallery via the hole previously drilled.
  • This head has either an expansion mechanism, a wedge type mechanism or any other solution well known to those skilled in the art of bolting (resin, cement, etc.) allowing it to either anchor itself definitively in the grounds by pushing or pulling, either to adhere to these grounds by resin or cements.
  • This thread allows, once threading, to "flatten” the flat iron against the wall using a steel plate tightened against the flat iron by a clamping nut adapted to the thread; preferably, a deformable steel plate is used which prevents the nut from being torn off under the pressure of the ground.
  • this flat iron which has longitudinal grooves over most of its length, allows the operator to drill with a minimum of safety through this flat iron as many holes as it wants depending on the bolting density he has chosen, then install these anchor rods which will make the flat iron adhere closely to the shape of the arch to be reinforced.
  • the grooves allowing the passage of the perforation florets and the anchor rods are preferably elongated, along the largest dimension of the element, so as to facilitate as much as possible the perforation and allow a greater choice as to the positioning of these rods.
  • each frame is made up of three elements: an upper element placed at the face of the wall and two lateral elements placed on either side in the extension of the first.
  • the side members are slightly different from the element su p E- laughing by the fact that they do not include in their oblong hole for guiding medium, as is the case for the element made. These two elements have a discontinuous groove over their entire length. Grooving stops increase the strength of the element.
  • these elements have at least one of their ends a nesting housing which facilitates their mounting.
  • the frame thus produced is relatively compact and is applied exactly against the wall of the gallery. It avoids all the problems of filling voids and makes it possible to reduce the digging section of the gallery due to its small thickness.
  • the dimensioning of the reinforcement can be different depending on the nature of the land and the operator's requests. The only constraint being a weight problem, so that the frame remains maneuverable by the staff.
  • the support device consists of a set of such reinforcements placed perpendicular to the axis of the gallery, spaced from each other by a distance depending on the nature of the ground.
  • This device can also be supplemented by the initial installation, on the wall, of a metal mesh which is then supported by all of the reinforcements and prevents the chipping of the ground between the reinforcements.
  • This trellis can also be covered with a layer of sprayed concrete capable of ensuring perfect homogeneity of the entire support.
  • the anchor rods or "bolts” (6) are threaded, after drilling the wall (1) in the hole (7 ') of the upper element and the grooves (7) of the three elements. They are either sealed or anchored in this wall and allow the reinforcing elements to be pressed there by means of the nuts (8) and the support plates (9).
  • the gallery wall (1) is covered with a wire mesh (10).
  • FIG. 2 shows, in section along the greatest length, a flat iron (2) constituting the upper element (3) provided with a hole (7 ') and grooves (7), on which is exerted, according arrow F, the thrust of the terrain wall.
  • FIG. 3 represents an upper element (3) seen from above, showing the arrangement of the grooves (7) which extend along the largest dimension of this element and of a central hole (7 ').
  • FIG. 4 an upper element (3) and a lateral element (4) are seen, the ends of which overlap by means of an interlocking housing (11) and are fixed to each other, and to the wall. . (1), with the wire mesh (10), using the anchor rod (6). The threaded end of the latter is threaded into two openings (7) of said elements placed opposite one another, and provided with a support plate (9) and a clamping nut ( 8).
  • Such a device makes it possible to support the wall under normal operating conditions without having recourse, either to conventional frames, .n to filling the voids and thus producing a support giving the gallery dimensions substantially close to those obtained after digging.
