Definitions

  • the invention relates to a profiled elastomeric seal intended to be installed and glued in a peripheral groove of a tunnel segment or the like.
  • the segments are segments of tubes, having a substantially rectangular or square outline comprising a peripheral groove in which a seal is received.
  • seals are in contact with one another and are compressed in the grooves of the segments, to form a sealing barrier with regard to the fluids contained in the surrounding land and also of a fluid contained in the tunnel or the well formed by the segments.
  • a segment joint generally comprises two parallel flat faces which are connected together by inclined flanks.
  • One of these faces intended to be applied to the bottom of the peripheral groove of the segment, comprises longitudinal support legs which determine between them parallel longitudinal grooves.
  • longitudinal channels parallel to these grooves, are formed in the joint, between these grooves and the other face of the joint.
  • the subject of the invention is an improved seal of this type, which is simpler to use than the seals known from the prior art.
  • the invention also relates to a joint of this type, which is capable of improving the seal between segments.
  • the invention also relates to a joint of this type, the characteristics of which are provided to facilitate the construction of the segments themselves.
  • a seal of the aforementioned type intended to be laid and glued in a peripheral groove of a tunnel segment or the like and comprising two parallel faces connected by inclined flanks, one of which, intended to be applied to the bottom of the groove, comprises longitudinal support legs delimiting between them parallel longitudinal grooves, characterized in that at least two neighboring longitudinal legs are connected together by a sole plate intended to be applied to the bottom of the throat of the segment.
  • Such a sole has several functions and has several advantages: - it prevents the longitudinal legs to which it is connected from lying under the compressive force of the joint during the assembly of the segments, - It plugs the bubbles or cavities that can be formed in the bottom of the peripheral groove of the segment, which in particular avoids the operations of taking up the grooves of the concrete segments. - it increases the bonding surface of the joint in the groove, and therefore allows better resistance of the joint to deformation and to extrusion or creep under the combined effects of the compressive force of the joint, the pressure of the fluid and the stresses due to slight positioning defects of the segments relative to each other.
  • Such a sole can be formed between all of the longitudinal legs of the joint, or else between some of them, in particular between the legs formed by the two longitudinal edges of the joint and the neighboring legs.
  • the inclined flanks of the joint which are connected to the abovementioned face comprising the longitudinal grooves, form an angle between approximately 12 and 60 ° and preferably between 30 and 60 ° with a perpendicular to this face of the joint.
  • the groove of the segment which has a shape conjugated with that of the part of the joint that it receives, then has flanks making an angle of between 12 and 60 ° approximately with the perpendicular to the flat bottom of the groove. This results in a simplification of the manufacturing of the segments, in particular at the mold level, when this angle is greater than or equal to approximately 30 °.
  • the segment joint comprises corner pieces which join together sections of joint, and these corner pieces are made either of hydro-swelling elastomer, or of elastomer of the same kind as the joint sections, but having a lower Shore hardness.
  • the aforementioned soles are interrupted in certain zones, in particular in these corner pieces.
  • the grooves which are closed by these soles can thus fill with the fluid in respect of which the sealing is carried out, which makes it possible to form several successive sealing barriers and to improve the resistance of the joint, thanks to the fact that the grooves in question are internally subjected to fluid pressure.
  • the joint also comprises parallel longitudinal channels formed in line with certain support legs and having in cross section an arch shape with curved walls, comprising a concave wall situated on the side opposite to corresponding supporting leg and two convex walls joined together on the side of the supporting leg.
  • FIG. 1 essentially represents a part of a concrete segment 10, comprising a peripheral groove 12 of trapezoidal section, in which a sealing gasket 14 is placed and glued.
  • this seal 14 is an elastomer profile, for example Neoprene or EPDM, or other similar material, having a Shore A hardness of between 50 and 80, depending on the conditions of use of the seal.
  • the joint comprises two parallel flat faces 16 and 18, connected together by inclined flanks 20, 22 forming a dihedral on each side of the joint.
  • the face 18 of the seal which is applied to the bottom of the groove 12, comprises parallel longitudinal grooves 24 which are delimited by parallel longitudinal support legs 26.
  • the grooves 24 have in cross section an isosceles triangle shape with a rounded apex, the short side of which is on the bottom of the groove 12, and the longitudinal legs 26 have a conjugate shape, that is to say a trapezoidal shape in cross section, except for the end jambs formed by the longitudinal edges of the joint, the shape of which is different due to the presence of the inclined sides 22.
  • the joint also comprises three longitudinal channels 28, formed in line with the three longitudinal legs 26 included between the longitudinal edges of the joint.
  • the seal 14 has a height greater than the depth of the groove 12 of the segment.
  • the support legs 26 are connected to neighboring legs by flanges 30 which close the corresponding grooves 24, on the side of the bottom of the groove 12.
  • the seal 14 comprises two soles 30 of this type, which close the grooves 24 extending along the longitudinal edges of the bottom.
  • the other two grooves 24 located on either side of the median longitudinal plane of the joint could also be closed by soles of this type.
  • the soles 30 have several functions. First, they prevent the longitudinal legs 26 to which they are connected from lying under the stress of crushing the joint. It is easily understood that the small base of a longitudinal leg 26, which is applied to the bottom of the groove 12 and which is connected to a sole 30, cannot move transversely on the bottom of this groove. This therefore improves the strength of the seal and avoids excessive deformation, detrimental to sealing.
  • the flanges 30 form an additional bonding surface for the seal on the bottom of the groove 12. This improves the resistance of the seal and its resistance to deformation and to extrusion or creep under the effects of the forces to which it is subject.
  • the soles 30 also have the function of closing off the bubbles or small flush cavities which can be formed in the bottom of the groove 12, which avoids any risk, ie leakage of fluid by these bubbles or small cavities. Consequently, it is no longer necessary to carry out an operation for recovering the bottom of the grooves of the concrete segments, aiming to obtain a substantially flat and smooth bottom.
  • the sides 32 of the groove 12 are more inclined than in the prior art makes it possible to increase the volume in which the seal 14 is housed when it is completely flattened. We can therefore use a joint which will be a little more solid than in the prior art, and therefore a little more resistant.
  • the channels 28 formed in line with the longitudinal legs 26 have in cross section an arch shape, comprising a concave curved wall located on the side of the face 16 of the joint, opposite the corresponding leg 26, and two convex curved walls interconnected on the side of the longitudinal leg 26, substantially on the axis thereof.
  • This particular shape of the channels 28 has many advantages. When the joint is crushed, it reduces the shearing forces, in particular ment thanks to the convex curved sides which allow a flattening of the channel 28 on the corresponding jamb 26. In the prior art, where the channels 28 generally have a circular section, this flattening causes an inversion of the curvature of the wall of the channel, and therefore a significant deformation and shearing force of the material. The lifetime of the seal according to the invention is, for this reason, much longer than that of the seals of the prior art.
  • the concave wall of the channels 28, located on the side of the face 16 of the seal is relatively slightly curved. This shape facilitates the insertion of the face 16 of the joint at the level of the channels 28, in particular when the joint is offset transversely relative to the joint of the adjacent segment such as that shown in phantom line.
  • the two faces 16 of the seals, bearing one on the other, are then wavy and nested one inside the other, to better oppose a displacement or a transverse deformation of a seal relative to the 'other.
  • FIG. 2 is a partial perspective view of a corner piece 34 connecting together two rectilinear sections of joint 14.
  • the corner piece 34 is substantially square and is molded by injection or by transfer to the ends of the joint sections 14.
  • the two branches of this part 34 have substantially the same cross section as the joint sections 14, but, as seen in FIG. 2, the flanges 30 can be there interrupted or have orifices 36, allowing the fluid in respect of which it is desired to seal, to penetrate into the corresponding grooves 24.
  • Several successive sealing barriers are thus produced, and the resistance of the seal is increased, thanks to the fact that the grooves 24 are then subjected internally to the pressure of the fluid.
  • each corner piece 34 can be made of hydrogonflating elastomer.
  • the part 34 in contact with the fluid, the part 34 will increase in volume and tend to completely close the segments of the segment groove in which it is housed.
  • each corner piece 34 can be made of an elastomer of the same kind as the profiled seals 14, and with a Shore hardness of 10 to 15 units less. This lower hardness of the corner pieces also improves the tightness at the angles or tops of the segments.
  • the profiled joint 14 comprises two longitudinal grooves 24 open, two longitudinal grooves 24 closed by flanges 30 and three longitudinal channels 28 formed in line with the longitudinal legs 26 defining the open grooves 24.
  • These numbers of legs and grooves depend on the maximum acceptable value of the transverse displacement of one joint with respect to the other, it is generally accepted that this maximum value must remain less than the half-width of the external face 16 of the joint.
