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 pressures.
  • 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.
  • It also preferably meets at least one of the following characteristics: - It has on its face opposite to that which is to be housed in the bottom of the throat a layer of water-swelling elastomer. - The thickness of the layer of water-swelling elastomer is 2 to 3 mm. - It is provided with longitudinal cells in the shape of an arch above the legs of its central area, and in the shape of a crescent moon turned towards its axis above its side legs. - The free volume occupied by its grooves, and possibly its alveoli, is equal to the volume of elastomer located at rest above the throat, increased by approximately 10%.
  • FIG. 1 shows in section two seals arranged opposite one another in opposite facing grooves, each provided with a sealing lip and with 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 each other has a groove in which a seal (3, 4) is arranged.
  • 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 comes the pressure of the water coming from surrounding terrain represented by the arrow to the left of the figure, is provided with a lip (20, 21) improving the tightness , the fact that the pressure of the water the plate against the corresponding flank of the groove in which is housed the seal, 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 represented 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.
