Definitions

  • the invention relates to a tunnel lining with in the longitudinal direction of the tunnel tubbing rings arranged one behind the other each arranged one behind the other in the circumferential direction of the tunnel segment-shaped segments are made of reinforced concrete.
  • segmental lining in the form of a general practice known segmental lining has difficult ground conditions, especially in connection with groundwater, where the N ⁇ T (new Austrian tunnel construction method) to its limits comes up with their advantages:
  • the segmental lining is suitable for both non-cohesive as well as cohesive soils, provided that this one not too flowable consistency.
  • the segments In loose rock and when there is groundwater, the segments are behind a tunnel boring machine driving in the shield drive. Supporting the mountains and closing off the groundwater through the sign the tunnel must open immediately Tubbing expansion can be taken over.
  • the segments must therefore an immediate load-bearing effect and, if necessary, immediate tightness have.
  • bedrock segments can be used as an alternative for shotcrete process behind full or partial cutting machines to be built in. In both cases, the use create a single-layer tunnel lining from Tübbingen, which is both security and expansion.
  • Tubbings are precast elements that are mostly made of reinforced concrete are manufactured.
  • the tunnel tube consists of individual Segment stones, the number of which depending on the tunnel diameter is.
  • the tubbing rings are against each other by half a stone length staggered to make it difficult to seal Avoid joint crossings.
  • the type of Tubbing design is block or cassette tubbing. At the In contrast to block tubbing, cassette tubbing becomes weight to save and to facilitate screwing the stones together, the cross section in the central stone area is greatly reduced.
  • the tunnel lining should be without loads absorb larger deformations, i.e. it must be for everyone Tunneling appropriate load cases can be dimensioned. Soil loads, groundwater, and dead weight are from the completed structure and record operational or traffic loads.
  • the object of the invention is to provide a tunnel lining, which in addition to the uses described above also Use in very soft cohesive soils is permitted and in cases strong tensile stress on the tunnel shell can be used can.
  • each segment ring on its inner surface with at least a circumferential, undercut recess is provided and the recesses are filled with in-situ concrete.
  • the segments are more similar to slab beams Structure and recesses built in; then they are in the Able to support and secure the excavation cross-section.
  • the reinforced bar area ensures perfect transmission of the ring forces, because the longitudinal joint through the existing Stone thickness of about 40 cm, for example, makes sense from a construction point of view can be trained.
  • the in-situ concrete rings in the corresponding dimensioned cutouts take over the transfer anyway of normal tensile forces occurring and prevent opening the longitudinal joints.
  • each segment ring in Area of its two inner ring edges, each with an undercut Recess is provided and the neighboring ones Cut-outs of the adjacent segment rings into one Complete recess groove; so it is particularly recommended if the recesses or recess grooves have a dovetail shape Have cross-section.
  • the ring joints are also particularly sealed.
  • the tunnel will be in very soft, cohesive soil opened, can build sheet metal sections with the construction of the segment ring placed in the recesses at the level of the longitudinal joints to an immediate bending stiffness of the segment ring achieve.
  • the sheet profile sections are with the segments or screwed together if necessary.
  • the recesses are then worked according to the reinforced and concreted with static requirements.
  • the arrangement so that the concrete filling the recesses as External ribs of an inner lining shell running in the longitudinal direction of the tunnel are made of in-situ concrete.
  • the Inner lining shell have additional reinforcement. Since the segment rings are subsequently concreted, the staggered installation of the tubbing rings among each other omitted because the in-situ concrete of the inner lining shell Seals in the areas of the longitudinal joints; the installation the tubbing is thus made easier for the construction site.
  • the tunnel linings shown in the figures show first arranged one behind the other in the longitudinal direction of the tunnel Tubbing rings 1, each in the circumferential direction of the tunnel segment-shaped segments 2 arranged one behind the other Reinforced concrete are built.
  • Each segment ring 1 is on his Inner surface with at least one circumferential undercut Provide recess 3 and the recesses 3 are backfilled with in-situ concrete.
  • the undercut dovetail-shaped Recesses 3 arranged in the middle of a segment ring 1.
  • each segment ring 1 in the area of its two inner ring edges each with an undercut recess 3, namely such that the adjacent recesses 3 of the side by side Segment rings 1 to a recess groove 4 with Complete dovetail cross-section.
