Definitions

  • the present invention relates to a tubbing arrangement for lining tunnels, consisting of a plurality of tubbing rings lying in ring joints, which are each composed of individual concrete tubbings, which, forming an articulated chain, are supported against one another in longitudinal joints, the longitudinal joints between the Concrete segments of adjacent segment rings offset from each other and the two end faces of each concrete segment are profiled such that the profiles have transmission surfaces for radial coupling forces between the segment rings and the profile of one end face is the negative form of the profile of the opposite end face.
  • segments Today, tunnels that are driven in the shield drive are mostly lined with concrete segments (hereinafter referred to as segments). For this purpose, the segments are assembled with the progress of the tunnel boring machine to form segment rings, which form the tunnel tube in a row. Each segment ring consists of several segments of approximately the same length, which lie against each other in longitudinal joints forming concrete joints. It is also common to use segments of the same length with a smaller keystone, which simplifies the completion of a segment ring.
  • the support of the tubbing tube by the building site is sufficient so that the deformation of the tubbing ring does not exceed a tolerable level despite the joints. In softer soils, however, the support of the tubbing tube is not sufficient. Measures must therefore be taken to compensate for the lack of support.
  • a coupling of the articulated rings in the ring joint is used, ie adjacent segment rings, in which the longitudinal joints are offset against each other in the manner of a brick structure, act together as a rigid segment shell.
  • this coupling of the tubbing rings is achieved by a profiled design of the tubbing end faces, in that each tubbing has a groove on one end face and a tongue on the other end face (tongue and groove System). Due to the staggered arrangement of the longitudinal joints of adjacent tubbing rings, the joints of the one tubbing ring are locked by the bending stiffness of the staggered neighboring ring, i.e. one segment ring gets the bending stiffness due to the soft floor from the neighboring ring.
  • the coupling forces acting on this are transmitted via the inclined contact surfaces of the tongue and groove pair, namely radially inwards and outwards, i.e. the coupling forces are transmitted as a pressure-resistant connection on both sides.
  • the tongue of the tongue-and-groove pair In order to be able to absorb or transmit the coupling forces, the tongue of the tongue-and-groove pair must have a certain radial extent, since if the design is too weak it will flake off, or at least could be damaged.
  • the necessary radial dimensioning of the tongue in turn requires a corresponding dimensioning of the groove, so that only about a third to a quarter of the wall thickness of the segment is available for absorbing the coupling forces, as can be seen from FIG. 2.
  • cracks are very common, extending from the groove to the outside or inside of the tubbing. In particular, the cracks to the outside are problematic, since they bypassing the sealing frame lead to a leak in the tunnel tube.
  • this object is achieved in a tubbing arrangement of the generic type in that the profile of the end faces of each tubbing is formed by only one paragraph, this paragraph being arranged in the central region of the annular joint.
  • the transmission surfaces for the coupling forces run approximately in the central region of the annular joint in the solution according to the invention, so that approximately half of the transmission forces for the coupling Tubbing wall thickness is available, and not only about a third to about a quarter as in the prior art.
  • the longer, possible crack level is now even better, or with smaller tubbing wall thicknesses, which are used in tunnels with smaller diameters, for example, with underground tubes, because only more concrete volume is available for the reinforcement stands.
  • the invention also offers the possibility of reducing the tubbing wall thickness under appropriate load conditions.
  • FIG. 1 shows a longitudinal section through the wall of two adjacent tubbing rings, the outer sides of which are at the top and the inner sides at the bottom in the drawing.
  • FIG. 2 is attached, which shows in an analogous manner a longitudinal section through the wall of two adjacent tubbing rings. Both figures are shown on the same scale.
  • Each segment ring 1, 2, which does not appear from the illustration, is composed of several segments that lie in longitudinal joints. These longitudinal joints form concrete joints, so that each segment ring 1, 2 is a chain of segmented segments. Adjacent segment rings 1, 2 are in turn in ring joints 3 together. These ring joints 3 are by means of of a sealing frame 4 sealed against water ingress, which is inserted into a complementary groove running around the end faces of the segment rings 1, 2.
  • the exemplary embodiment for the invention does not differ from the prior art.
  • the end face on the right seen from the outside, begins with an essentially vertical section that extends approximately to the middle of the annular joint 3. There the end face then jumps in obliquely inwards and downwards in a step 5, in order then to merge again into a substantially vertical section which extends to the inside.
  • the paragraph 6 is formed by a section which projects equally outwards and downwards.
