Definitions

  • the invention relates to a tunnel lining with segment rings arranged one behind the other in the longitudinal direction of the tunnel, each of which is made up of segment-shaped segments made of reinforced concrete arranged one behind the other in the circumferential direction of the tunnel, the longitudinal joints running between the segments of a segment ring being staggered with respect to the longitudinal joints of the neighboring segment rings, the segment segments also being offset are provided on their one ring end face with at least one segment-shaped recess and on their other ring end face with segment-shaped elevations encompassing the recesses of the tubbings of an adjacent tubbing ring, and finally, joint inserts are interposed between the adjacent ring end faces.
  • the individual segments are mounted in the area of the shield by means of an erector.
  • the ring closure is formed by a keystone, which closes the segment ring as the last segment element.
  • This keystone and the tubbings on both sides are wedge-shaped. With this construction, the tubbing ring receives the necessary contact pressure for the ring closure.
  • the individual segments are arranged so that the segment rings are each offset by half a segment element. Problematic cross joints are avoided.
  • Sharp-edged tongue and groove constructions are usually chosen for the construction of the ring joints. Due to this relatively filigree sharp-edged construction, chipping occurs repeatedly when installing the segments if the sharp-edged contours come into unscheduled pressure contact due to dimensional deviations during assembly. This fact can lead to severe restrictions on the usability of a tunnel structure, especially if cracks and gaps occur on the earth side due to these flaking.
  • sealing frames are usually inserted and glued into a groove construction in the tubbing. These sealing frames ensure the watertightness of the tunnel structure in the long term through a defined contact pressure. In the described spalling of the concrete structure, however, the sealing frame in question is no longer able to guarantee permanent water resistance.
  • the invention has for its object to develop the tunnel lining of the type mentioned so that it takes into account increased construction speeds on the one hand, and on the other hand meets special requirements for stability and usability.
  • the recesses and elevations have a rounded shape with a wavy contour in radial section and the joint inserts are provided at least in the turning point areas of the wavy contour.
  • the wavy contour of the recesses and elevations in the radial section each has a central circular arc section and flat contact surfaces in the adjoining turning point regions, the central circular arc sections of the recesses having a smaller radius of curvature than that of the elevations and the mutually associated contact surfaces running parallel to one another.
  • the central sections of the circular arc can also be flattened at the apex.
  • the recesses and elevations should have a trapezoidal contour with rounded corners in the circumferential section. If, as in a preferred embodiment, the adjacent ring end faces between the joint inserts have different thicknesses, ovalization effects resulting from assembly tolerances or deformations in the final state can be compensated for.
  • joint inserts running radially and / or in the circumferential direction along the contact surfaces.
  • circumferential, mutually associated sealing frames should be introduced, for example glued, into the ring end faces of adjacent tubbing rings in the outer edge region.
  • neoprene, kaubite, softwoods, etc. controls the load-deformation behavior of the joint inserts and additionally the load distribution in the flanks so that there is a high level of work capacity to absorb coupling forces and constraining forces in the segment construction.
  • the variation of the material of the joint inlays enables a defined coupling rigidity.
  • the overall system of the segment lining can be easily adapted to all conceivable load and deformation conditions.
  • the forced construction of the segments with each other which is required for fast ring construction, can also be ensured by the new design.
  • the inclination of the pot flanks can be matched to the size of the press forces acting on the shield.
  • the smooth joints in the area of the press shoes are used to compensate for tolerances, for example in the case of imprecise positive locking as a result of ovalization in the ring direction. These joint zones have the same effect as the constrictions that were customary up to now.
  • the option of guiding the selected joint training over the entire ring joint there is of course the option of guiding the selected joint training over the entire ring joint.
  • the flattening in the area of the press shoes can then be omitted.
  • the necessary tolerance compensation with possible ovalization takes place over larger joint widths, especially on the flanks.
  • the deformability of the segment ring is controlled and limited by the joint inserts. This is possible on the one hand by adapting the surface pressures and on the other hand by materials with appropriate stiffness gradations.
  • the shape of the press shoe must of course be adapted to the shape of the ring joint. With a geometrical assignment to the direction of advance, the press shoe must be shaped like a recess.
  • the press shoe must be one Get elevation-like shape.
  • the driving forces are transferred to the already installed segment rings via joint inserts in the center of the recess / elevation construction.
  • the advantage of this alternative solution is the equalization and adaptation of the joint inserts to the coupling force transmission.
  • the geometric changes in the ring joint as a result of ovalization can be further equalized and improved.
  • Another advantage is the simplification of the tubbing formwork.
  • the tunnel extension system can be adapted to all possible load and deformation conditions.
  • a variation between the alternative or resistance principle is possible.
  • the parts shown in the figures belong to a tunnel lining with segment rings arranged one behind the other in the longitudinal direction of the tunnel.
  • the segment rings are each made up of segmented segment segments 1 made of reinforced concrete arranged one behind the other in the circumferential direction of the tunnel.
  • the longitudinal joints running between the segments 1 of a segment ring are offset from one another to the longitudinal joints of the neighboring segment rings.
  • the tubbing rings 1 are provided on their one ring end face with at least one segment-shaped recess 2 and on their other ring end face with segment-shaped elevations 3 which surround the recesses 2 of the tubbing rings 1 of an adjacent tubbing ring.
  • joint inserts 4, 5 are interposed between the adjacent ring end faces. All of this is only partially apparent from the figures, since the construction of such a tunnel lining is well known in the prior art.
  • the recesses 2 and elevations 3 have a rounded shape with a wavy contour in radial section and the joint inserts 4 are provided at least in the turning point areas of the wavy contour.
  • the arrangement is such that the wavy in radial section Contour of the recesses 2 and elevations 3 each have a central circular arc section 6 and in the adjoining turning point areas flat contact surfaces 7, the central circular arc sections 6 of the recesses 2 having a smaller radius of curvature (Ra ⁇ Ri) than that of the elevations 3 and the mutually associated contact surfaces 7 run parallel to each other (see FIG. 2).
  • the recesses 2 and elevations 3 have a trapezoidal contour with rounded corners in the circumferential section (cf. FIG. 3).
  • joint inserts 4 are arranged to run radially along the contact surfaces 7.
  • the joint inserts 4 in the embodiment according to FIGS. 4 and 5 are arranged in the circumferential direction along the contact surfaces 7. A combination of these two arrangements would of course also be possible.
  • joint inlays 5 are arranged between the recesses 2 and elevations 3 for transferring press forces.
  • 1, 2 and 4 and 5 also show that in the ring end faces of adjacent tubbing rings, circumferential, mutually associated sealing frames 8 are introduced, in particular glued, in the outer edge region.
  • 2 also shows the course of the reinforcements 9 in the area of the recesses 2 and elevations 3, which can be adapted particularly well to the curved contour of the elevation 3 and is thus particularly resilient.
  • Fig. 6 illustrates unequal modifications.
  • the central arc sections 6 at the apex with a flattening 10 i.e. are provided with, as it were, interposed, flat areas perpendicular to the longitudinal joints.
  • the joint inserts can have 4 different thicknesses; In this way, a deformation game is specified, via which the time of load transfer in the circumferential direction of the tunnel can be influenced.
