Definitions

  • the invention relates to an elastomeric, strand-shaped sealing profile for a circumferential receiving groove tunnel segment with a base side, a rear side, the width of which is less than the width of the base side, and Flank sides that connect the base side with the back side.
  • Sealing profiles for sealing the gaps between tunnel segments are, for example from DE 35 26 063 A1, DE 37 20 919 A1, DE 40 26 076 A1, DE 41 03 089 A1, DE 196 03 188 A1, CH 679 510 A5, EP 306 581 A1 and EP 522 912 A1 known.
  • sealing tunnel segments with circumferential grooves are usually four sealing profiles by means of associated Frame corners to one in the circumferential receiving groove of the tunnel segment arranged sealing frame formed.
  • Those with sealing profiles in their tunnel segments or tubbings provided with circumferential grooves are assembled into rings, which in turn form a complete tunnel tube are composed, as is the case, for example, in DE 196 03 188 A1 is described.
  • the water pressure, against which a seal is reliable To be guaranteed is in the range of 1 to 4 bar, which is located at the English Channel tunnel Pressure in the range of 10bar, further tunnel projects are conceivable and planned, where this sealing pressure is significantly higher, for example at 30bar.
  • a reliable seal should also be used for relatively large ones Gap widths between the tunnel segments can be achieved. It can too a subsequent gap opening due to deformation of the original circular tunnel tube come through ovalization.
  • DE 35 26 063 A1 describes a sealing profile with two rows offset Channels known, which is too soft for high water pressures.
  • the end DE 37 20 919 A1 known sealing profile is relatively flat in height, which is why it is not able to seal high water pressures with larger gaps.
  • Seals according to DE 40 26 076 A1 move laterally attacking water pressure, causing the originally intended sealing effect the spreading foot is lifted.
  • DE 41 03 089 discloses a sealing profile known with two rows of channels arranged one above the other, vertical and obliquely continuous webs are formed. When pressed together without deform a lateral offset of the opposite grooves these sealing profiles so that they twist internally and a side Cause shifting of the tunnel segments to each other.
  • a sealing profile is also known, which in Area of his back has a groove-shaped recess into which a strip-shaped Insert part can be clipped in, which is made of a water-swelling material consists. If due to a deteriorating sealability water to this Penetrates insert, the water-swelling material increases its volume, causing additional sealing stresses are built up.
  • Seals made of water-swellable sealing materials for high, low and Civil engineering, especially for sealing joints and compensating for dimensional changes of components are known. Such water-swelling are described Sealing materials, for example in WO 99/35208, the documents cited therein, EP 0 692 584 B1 and the documents contained therein scripture in this context.
  • the object of the invention is to provide an elastomeric strand-shaped sealing profile Provide the type mentioned at the beginning, through which a safe and permanent Sealing against very high water pressures is made possible. According to the invention this is achieved by a sealing profile with the features of claim 1.
  • the sealing profile can move against the opposite one Support the groove flank and is only slightly shifted sideways.
  • the cantilever arms are essentially trapezoidal Base body of the sealing profile arranged.
  • the sealing profile can be designed that the profile can completely disappear in the groove and the restoring forces remain within acceptable limits.
  • the maximum sizes of the restoring forces should not be too high, for example, the groove surrounds of the Don't let the tunnel segments flake off.
  • the total cross-sectional area of the Sealing profile can for example be in the range of approximately 90% (+/- 5%) the cross-sectional area of the receiving groove.
  • the water-side sealing lip in the area of the corners between the base side and the respective flank side of the sealing profile outgoing sealing lips is pressed and sealed against the groove flank by the water pressure automatically.
  • the presence of water is due to training an additional sealing pressure is built up from a water-swellable material, by increasing the volume of the sealing lip. This will make the sealing lip against the groove wall on the one hand and the flank side of the sealing profile on the other hand pressed and seals effectively.
  • these can Sealing lips made of a softer material than the main body of the sealing profile exist, so that these sealing lips very well on the bumps can adapt to the concrete surface.
  • the Y-shaped structure of internal Includes webs, high restoring forces can be dissipated in the center of the groove.
  • that at least two rows of distributed across the width of the sealing profile Channels are provided.
  • the base side of the sealing profile is closed Stand area is formed, that is without starting from the stand area, Grooved grooves reaching inside the base part.
  • the footprint is therefore essentially just trained.
  • Such a full-surface footprint of the sealing profile allows an excellent gluing of the profile in the groove what in turn contributes to the stability of the seal formed.
  • a co-extruded in the web forming the back of the profile Insert made of a water-swelling material is arranged. If there is of water, especially as a result of a loss of force in the compression seal when the gap opens, the volume of this insert increases, thereby an additional compressive stress is generated which represents the loss of force of the compression seal compensates or overcompensates.
  • Fig. 1 two opposite grooves 1 are schematically in adjacent Tunnel segments 2 shown.
  • Each tunnel segment 2 has its own Side surfaces insert a circumferential receiving groove 1 in the sealing profiles are.
  • the grooves have a groove base 3 and groove flanks 4. Between the Tunnel segments 2 is a gap with the width a through which in the grooves sealing profile used is to be sealed.
  • the groove centers of the opposite Recording grooves can have a certain lateral offset d.
  • the embodiment shown in cross section in Fig. 2 of an inventive Sealing profile is shown in its relaxed state and the The groove in which it is to be inserted is indicated by dashed lines.
  • the elastomer, extruded sealing profile comprises a base side 6, a back side 7, whose width b is less than the width B of the base side 6.
  • the base side and the back side are connected by flank sides 8.
  • the sealing profile has an isosceles trapezoidal shape seen in cross section Base body 5, whose parallel sides from the base side and the back of the sealing profile.
  • the base body 5 is interspersed by a crossbeam 10 on the opposite flank sides 8 of the sealing profile protrudes beyond the base body 5.
  • the imaginary legs of the trapezoidal base body are in the area of the cantilever arms 9 indicated by dashed lines.
  • These cantilever arms 9 are in one piece with the base body 5 formed and made of the same material as the base body.
  • the cantilever arms 9 are located in an area of the flank sides that both of the Base side, as well as spaced from the back side. A co-extruded one Formation of these cantilever arms 9, the cantilever arms 9 made of a material of another Hardness like the basic body could exist would be conceivable and possible.
  • the section of the crossbar lying within the base body 5 10 runs approximately parallel to the base side 6 of the sealing profile.
  • the about the Base body 5 laterally projecting cantilever arms 9 rest with their free ends the groove flanks 4.
  • the width of the sealing profile distributed channels provided.
  • Above the crossbar 10 is a series of three channels 11, 12, 13 which are triangular in cross section arranged.
  • Below the crossbar is a row adjacent to the base side Channels 14-17 in the form of each closed by a wall 18 Groove grooves arranged.
  • the high points of these closed groove grooves form an imaginary parabolic arch, the maximum of which is in the center of the profile lies and the corners 19, 20 between the base side 6 and the adjacent Flank sides 8 cuts.
  • Between the two side channels 14 and 17 and the crossbar 10 are also circular channels in cross section 28, 29 arranged.
