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 constructed from segmented segments made of reinforced concrete arranged one behind the other in the circumferential direction of the tunnel.
  • Such a tunnel lining in the form of a segmental lining has its advantages in difficult ground conditions, especially in connection with groundwater, where the NTM (New Austrian Tunneling Construction) reaches its limits:
  • the segmental lining is suitable for both non-binding and for cohesive soils, provided they have a consistency that is not too fluid.
  • the segments In loose rock and in the presence of groundwater, the segments are installed behind a tunnel boring machine driving in the shield. The support of the mountains and the shielding of the groundwater by the shield must be taken over immediately by the tubbing extension when the tunnel is opened. Tubbings must therefore have an immediate load-bearing effect and, if necessary, an immediate seal.
  • segments can be installed in solid rock behind full or partial cutting machines. In both cases, the use of tubbing can be used to create a single-layer tunnel lining that is both securing and removing.
  • Tubbings are precast elements that are mostly made of reinforced concrete today.
  • the tunnel tube consists of individual segment stones, the number of which depends, among other things, on the tunnel diameter.
  • the tubbing rings are installed offset against each other by half a stone length to make them difficult to seal Avoid joint crossings.
  • the usual type of tubbing design is block or cassette tubbing. In contrast to block tubbing, in cassette tubbing, in order to save weight and facilitate screwing the stones together, the cross section in the central stone area is greatly reduced.
  • the tunnel lining should absorb acting loads without major deformations, ie it must be able to be dimensioned for all load cases corresponding to tunnel construction. Soil loads, groundwater, dead weight and operating or traffic loads are to be absorbed from the completed structure.
  • the object of the invention is to provide a tunnel lining which, in addition to the possible uses described above, also allows use in very soft, cohesive soils and can be used in cases of high tensile stress on the tunnel shell.
  • each segment ring is provided on its inner lateral surface with at least one circumferential, undercut recess and the recesses are filled with in-situ concrete.
  • the securing or expansion is primarily affected by normal pressure forces and bending moments, which result from deformation-dependent soil loads and possibly existing groundwater.
  • the segments are installed with a structure similar to slab beams and the recesses; they are then able to support and secure the excavation cross-section.
  • the reinforced beam area ensures perfect transmission of the ring forces, since the longitudinal joint can be designed in a constructive manner due to the existing stone thickness of about 40 cm, for example.
  • the in-situ concrete rings in the correspondingly dimensioned recesses in any case take over the transmission of normal train forces and prevent the longitudinal joints from opening.
  • each segment ring is provided with an undercut recess in the area of its two inner ring edges and the adjacent recesses of the segment rings lying next to one another complement to form a recess groove;
  • the recesses or recess grooves have a dovetail cross section.
  • the ring joints are also particularly sealed. Due to the dovetail-shaped design of the recesses, existing external water pressure, which can build up in the area of the composite joint, can be absorbed and removed from the overall cross-section.
  • sheet metal sections can be placed in the recesses at the height of the longitudinal joints with the construction of the segment ring in order to achieve immediate bending rigidity of the segment ring.
  • the sheet profile sections are screwed to the segments or, if necessary, against each other.
  • the recesses are then reinforced and concreted in accordance with the structural requirements.
  • the concrete filling the recesses is in the form of outer ribs of an inner lining shell made of in-situ concrete and running in the longitudinal direction of the tunnel.
  • the inner lining shell can have additional reinforcement. Since the segment ring joints are subsequently concreted, the staggered installation of the segment rings can be done with each other omitted, since the in-situ concrete of the inner lining shell takes over the seal in the areas of the longitudinal joints; the installation of the segments is thus made easier for the construction site.
  • the tunnel linings shown in the figures initially have segment rings 1 arranged one behind the other in the longitudinal direction of the tunnel, each of which is constructed from reinforced concrete segment-shaped segments 2 arranged one behind the other in the circumferential direction of the tunnel.
  • Each segment ring 1 is provided on its inner lateral surface with at least one circumferential undercut recess 3 and the recesses 3 are filled with in-situ concrete.
  • the undercut dovetail-shaped recesses 3 are arranged in the middle of a segment ring 1.
  • FIGS. 3 the embodiments according to FIGS.
  • each segment ring 1 is provided with an undercut recess 3 in the area of its two inner ring edges, in such a way that the adjacent recesses 3 of the segment segments 1 lying next to one another form a recess groove 4 with a dovetail-shaped Complete cross section.
  • Fig. 2 shows that adjacent segments 2 of a segment ring 1 can be screwed together by means of sheet metal profile sections 5 introduced into the recesses 3 before the in-situ concrete filling.
  • the in-situ concrete located in the recesses 3 can be reinforced. Furthermore, the figures do not show that there can be an annular space between the mountains and the tubbing rings, which can be filled with mortar, concrete or synthetic floor after or during the assembly of the tubbing rings.
  • the concrete filling the recesses 3 are designed as outer ribs 6 of an inner lining shell 7 running in the longitudinal direction of the tunnel and made of in-situ concrete.
  • the continuously concreted inner lining shell 7 ensures the tightness of the reinforced concrete composite construction to a particular degree, especially when using segments with a central recess.
  • This inner lining shell 7, which is also not shown, can have additional reinforcement.
