Definitions

  • the present invention relates to a profiled elastomeric seal intended to be placed in a peripheral groove of a tunnel segment, with a flat bottom and inclined edges, and having a face which must be housed in the bottom of the groove provided with several grooves extending parallel in the longitudinal direction, framed by support legs, and a substantially planar opposite face.
  • the object of the present invention is to provide a seal for a tunnel segment which has a better seal than known seals in the presence of high liquid pressure.
  • the seal according to the invention is characterized in that its leg located on the side where the pressure of the liquid is exerted against which it is desired to seal, or its two lateral legs, have a bearing lip on the corresponding inclined edge of the segment groove.
  • Figure 1 shows in section two seals arranged opposite one another in opposite facing grooves, each provided with a sealing lip and a layer of water-swelling rubber.
  • Figure 2 shows two seals arranged face to face, each provided with a sealing lip and longitudinal cells in the shape of an arch and crescent moon.
  • each of the segments (1, 2) facing one another has a groove in which is placed a seal (3, 4).
  • the seals each have a flat face, these square faces pressing against each other along the contact plane 5.
  • the opposite faces of the seals are each provided with three longitudinal grooves, a central groove (6,7) and two lateral grooves (8, 10; 9, 11). These grooves are framed by legs (12, 14, 16, 18; 13, 15, 17, 19).
  • the lateral jamb (18, 19) disposed on the side from which the pressure of the water coming from surrounding terrain comes, represented by the arrow to the left of the figure, is provided with a lip (20, 21) improving the seal. , the fact that the pressure of the water the plate against the corresponding flank of the groove in which the seal is housed, and against the bottom of this groove, as shown by the arrows near the side legs of the joints.
  • the area of the two seals near their flat face is made of a water-swelling elastomer, preferably with a thickness of 2 to 3mm. It is known that such elastomers can undergo volume increases of 100% in contact with water.
  • the seals shown in FIG. 2 allow a greater crushing stroke of the seals for an identical force exerted by the segments.
  • Each joint is drilled above of its central legs (12, 14 or 13, 15) of longitudinal arch-shaped cells 24, 26 or 25, 27, and above its lateral legs of longitudinal crescent-shaped cells facing towards axis of the joint 28, 30 or 29, 37. These cells prevent the appearance in the joints during crushing of shear zones liable to cause their deterioration, as would be the case if they were pierced with circular cells.
  • the free volume corresponding to the grooves, and optionally to the cells, is preferably chosen to be approximately 10% greater than the volume occupied by a seal at rest above the groove, so as not to subject the seal during its crushing to excessive stresses likely to degrade it.
