Definitions

  • the present invention relates to a device for positioning a segment joint for a tunnel in its housing groove.
  • the segments for tunnels in areas exposed to water infiltration are made up of polygonal elements, generally quadrilateral and delimited by two generators or two straight segments, especially when it comes to key or key elements.
  • the joints tend to form projections at angles of the segment.
  • the joint of the other segment no longer finds its place and partially leaves its groove, which leads to a leak in the contact zone of the two angles.
  • Such a seal if it largely remedies the possibility of leakage at the angles of the segments, is complex and requires that one has the seal elements in a vulcanization mold, in that one uses in the areas of the seals intended to come on the corners with a more compressible elastomer, in that one fills an area of the corner left free with a plastic material, then in that one carries out the vulcanization so as to remove any continuity solution in corner areas.
  • This device is complex and requires special treatment of the joint on site.
  • the object of the present invention is to provide a device for positioning a segment joint which is simple and allows easy and rapid installation of the joints in the grooves of the segments, and of the segments in the tunnel as it is excavated. .
  • the positioning device is characterized in that it comprises, in the vicinity of each angle of the groove of a segment, and on either side of this angle, two blind holes, and on the joint area intended to surround the segment around this angle, two fingers of cross section and depth close to that of the blind holes, at a distance from one another equal to that separating the blind holes in the groove, and intended to come s 'insert into them.
  • Figure 1 shows in perspective a segment angle and the blind holes for housing the positioning fingers of the seal, on either side of this angle.
  • Figure 2 shows in section and in perspective the seal in the area of a positioning finger.
  • Figure 3 shows in section through the median plane of the groove of a segment this segment and the joint around an angle.
  • FIG. 4 is a section along the axis IV-IV of FIG. 3.
  • FIG. 5 is a section along the axis V-V of FIG. 3.
  • the segment 1 is provided on its periphery with a groove 2 for housing the seal 3.
  • the latter has a flat face 4, which protrudes beyond the surface of the segment before the positioning of the adjacent segment, which will compress the joint, and on the other side of this planar face inclined sides 5, 6.
  • the other face of the joint is provided with grooves, for example a central groove 7 and grooves side 8, 9 separated by legs.
  • Housing 10, 11 near the angle 12 are intended to accommodate the fingers of the joint of cross section and corresponding depth. They are of rectangular cross section substantially constant over their depth, but could be of different cross section and decreasing with depth, provided that they allow good attachment of the fingers of the joint.
  • Figures 3, 4 and 5 show how to adjust the seal 3 in the groove 2 of the segment.
  • the seal engages in the groove 2 a little below the level of the edges of the groove, and its finger 13 is housed in the blind hole 10 in the throat of the segment, so as to ensure its precise positioning at the in the vicinity of the angle 12.
  • the adjacent segment When the adjacent segment is put in place, it compresses the seal in the groove, the grooves 7, 8, 9 allowing this material from the seal to be pushed back.
  • the retention of the fingers such as 13 of the joint on either side of the angle in the housings 11, 12 prevents the joint from projecting above the angle, and it ensures the maintenance of the sealing.
