Definitions

  • the present invention relates to a device for assembling two adjacent segments of a tunnel lining, in particular a railway tunnel.
  • French patent 79 00 884 describes a device for assembling the segments of a tunnel lining, constituted by cylinder segments whose opposite flanks have a certain curvature. This device consists of two pairs of corners, each disposed at one end of the segments, placed in corresponding housings of these connected radially by bolts which bring each corner closer to one another while tightening them in contact with the sides adjacent to the segment.
  • French patent 73 29 114 also discloses a segment assembly system consisting of a series of prismatic wedges chosen from one. range of dihedral angles suitable for the angle according to which the segments are to be assembled, these shims being superimposed between the segments and the assembly being blocked by bolts and nuts.
  • This assembly device requires having a whole range of shims.
  • the object of the invention is to propose a device for assembling segments that does not have these drawbacks.
  • the device for assembling the segments comprises a shim extending substantially over the entire length of the flanks opposite the segments, and the opposite faces of which have curvatures conjugated with the curvature of the corresponding sides of the segments, as well as means for fixing the segments together and to the wedge interposed between their sides.
  • the faces of the wedge have concavities whose radii of curvature are equal to the radii of curvature of the associated sides of the segments, and the width of the wedge is practically equal to that of the sides.
  • FIG. 1 There is shown in Figure 1 two adjacent segments 1, 2, intended for the constitution of a tunnel lining in particular rail, and a device for assembling these segments according to the invention.
  • the segments 1, 2 are constituted by cylinder segments made of cast iron or another suitable material, each comprising end veils 3 belonging to the upper surface of the covering, an intermediate veil 4 belonging to the lower surface of the covering, thus that two end walls 5 and radial ribs 6, 6a.
  • the ribs 6 connect the sails 3 to the sails 4, the rib 6a projecting radially between the two sails 4 of the lower surface.
  • Each segment 1, 2 has a side 7, 8 having a convexity of appropriate radius of curvature, these convexities being directed towards one another.
  • the sides 7, 8 are each pierced, in the vicinity of their ends, with two pairs of holes 11 adapted to receive bolts 14 associated with fixing nuts 16, each bolt 14 passing through holes 11 opposite each other to a segment 1.2.
  • the segments 1,2 can be assembled by means of a device which comprises a calel2 which extends over practically the entire length of the sides 7, 8 and over their entire width.
  • the opposite faces 12a of the wedge 12 have curvatures conjugated with the curvature of the corresponding sides 7, 8, and therefore have concavities extending from one end to the other of the wedge.
  • the radii of curvature of these concave flanks 12a are equal to the radii of curvature of the convex flanks 7, 8.
  • the shim 12 is pierced with a pair of oblong slots 13, suitable for allowing the introduction of the bolts 14 which therefore each pass through two holes 11 located opposite and the corresponding oblong opening .13
  • the nuts 16, screwed onto the threaded rods of the bolts 14, make it possible to block together the segments 1, 2 and the wedge 12.
  • Openings 10 are formed in the vicinity of the ends of the wedge 12 between the lights 13, as well as openings 15 in the central region of the wedge 12, to lighten the latter.
  • the assembly of the assembly device for the segments 1; 2 constituted by the shim 12 and the bolt 14-nut systems 16 is carried out as follows.
  • the segments 1, 2 are first held with their sides 7 and 8 facing one another so that the pins 24 of the segment 1 are opposite corresponding housings 25 of the segment?, But remaining separated by a sufficient interval. Is introduced between them the wedge 12, whose openings 10 are crossed by the pins 24, then the bolts 14 are mounted through the holes 11 and the slots 13, and the corresponding nuts 16 are screwed without fully tightening.
  • the angle ⁇ between the planes tangent to the wings 3 of the respective upper surfaces of the segments 1 and 2, at the level of their interface materialized by the sides 7, 8, depends on the 'radial position of the wedge 12 between the segments.
  • FIG. 4 illustrates a first example of angular positioning of the segments 1 and 2 relative to one another, in which the angle ⁇ 1 is equal to 180 °, the planes tangent to the webs 3 thus being combined.
  • the shim 1 2 is pushed towards the upper surface of the covering, by lightly striking the lower edge 12b of this shim, until this edge 12b as well as the opposite edge 12c are practically located in the planes tangent respectively to the lower surface sails 4 and to the upper surface sails 3 ( Figure 4).
  • the extension of the slots 13 in the radial direction of the cylinder segments constituting the segments 1, 2 allows the radial sliding of the wedge 12 relative to the rods of the bolts 14 in these slots 13.
  • the nuts 16 are then fully tightened on the bolts 14, whose hexagonal heads come to bear on washers 17 engaged in the holes 11, as well as the nuts 16 are supported on washers 17 analogs engaged in the corresponding holes 11.
  • the angle ⁇ 1 can be slightly varied on either side of the value of 180 °, as illustrated in Figures 5 and 6.
  • this angle which has become 0 (2 is equal to 184 °, and was obtained by moving the shim 12 towards the underside of the covering by the desired value so that the planes tangent to the sails 3 of extrados make between them this angle of 184 °.
  • This operation requires first loosening the nuts 16, starting from the position of the segments 1, 2 shown in Figure 4.
  • the average radius of the segment assembly is obtained by placing them in their relative position in Figure 4, the minimum radius corresponds to their angular position in Figure 5, and the maximum radius corresponds to the position in Figure 6 .
  • the assembly device constituted by the single wedge 12 and its fixing members 14, 16 to the segments 1, 2 has the advantage of allowing easy and rapid adjustment of the angular position of the segments. Indeed, it suffices to place the shim 12 in the correct position with respect to the sides 7, 8 by exerting sufficient pressure on one of its edges 12b, 12c, then tightening the bolts 14 and the nuts 16 completely.
  • the wedge 12 is first installed in its position in FIG. 5 where the radius of curvature of the segments is minimal (angle ⁇ 2 equal to 184 °), then the wedge 12 is pushed back by striking lightly on its lower edge 12b .
  • this single wedge 12 Another advantage of this single wedge 12 is linked to the fact that it distributes almost uniformly over its entire length the stresses undergone by the segments 1,2, which prevents the appearance of significant plasticization of said wedge and segments 1, 2 in the load area. Indeed, the forces being distributed over practically the entire surface of the wedge 12, there is great "flexibility” in the connection between the segments 1 and 2 provided by this wedge. This connection can even be considered as “elastic", tests having shown that after application of significant efforts, the segments 1, 2 could resume their initial shape.
  • the tightening of the bolts 14 has a significant influence on this flexibility: the shim 12 better taking up the forces undergone, the bolt connection of the segments is less stressed.
  • the forces mentioned above are in practice bending forces due to the weight of the ground, and compression by arch effect between the adjacent segments.
  • the initial shape of the segments 1, 2 is, more precisely, that obtained at the assembly level. This is how, for example, when using segments to consolidate a tunnel with a radius smaller than that of the ring formed by the segments, the application of forces has the effect of opening the angle ⁇ initially planned. If these efforts cease, the angle returns to its initial value.
