  • the individual segments may be made of cast iron or concrete, for example, the cast-iron variant is also used as a lost formwork for a subsequent Ortbetonausposed.
  • the single-shell design tends to be preferred, which at the same time fulfills optical and static requirements while at the same time being impermeable to water.
  • the EP 1 762 698 A1 discloses a compliance element for elongated underground spaces.
  • the embodiment provides that it is integrated between two arranged in the circumferential direction of the tunnel tube and separated concrete shells.
  • the forces are distributed in circumferential ring forces and transmitted to the compliance element, which yields under the occurring rock pressure by being compressed.
  • the embodiment shows a substantially honeycomb structure, the cavities are reduced during compression. Basically, this element fulfills its yielding task well.
  • the EP 2 042 686 B1 describes a continuation of the from EP 1 762 698 A1 known compliance element. This can also be subsequently changed in the already installed state between the concrete shells in that an increased resistance can be generated by the existing cavities are reinforced by the insertion of other hollow body. In practice, this significantly improves the individual adaptability to local conditions.
  • the solutions shown are particularly suitable for local use in underground composite structures, which are composed of gutter profiles or lattice girders in combination with an in-situ concrete shell.
  • the compliance element are each inserted between two mutually compliant to be designed Ortbetonschalen and embedded in this by means of connection reinforcement double-sided on site.
  • the reference to the use in tubbing construction methods is mentioned, but the practical implementation is not given here, since the known tubbings are spent as finished elements at the place of installation and allow any subsequent integration in the solidified concrete body.
  • the tubbing insert is used in practice as a clocked method, in which the local introduction of a compliance element between two circumferentially opposite tubbing would lead to inaccuracies and unrealizable viable connections with each other.
  • the compliance element does not have a compact design that can be seamlessly integrated into the precise fabrication of modern tubbings.
  • the disclosure EP 0 631 034 B1 a controllably compressible thrust bearing for segments in a tubbing ring of elastically deformable material. This is arranged in each case in the butt joint between two in the circumferential direction one behind the other with the end faces to a tubbing ring composite tubbing.
  • the structure of the compliance element is visually based on the known design of a Langlochziegels. This is mainly composed of mutually parallel webs, which intersect each other and thus form a plurality of rectangular continuous cavities. The cavities extend in the installed state between the opposite end faces of the tubbings.
  • the control of the elastic compliance is achieved by filling the cavities with a plastically deformable filling material, wherein the individual cavities are sometimes interconnected by lines and allow drainage of the excess by compression and displaced filling compound.
  • the necessary bond between tubbing and pressure bearing takes place by means of a bond.
  • the invention is therefore an object of the invention to provide a tubbing expansion as a tubular inner shell of a tunnel or shaft, which allows a controlled and permanently viable and limited deformability in the circumferential direction, with its innovations being seamless in the prefabrication and integrate the fast and reliable installation of modern tubbings.
  • the invention provides a tubbing removal as a tubular inner shell of a tunnel or shaft, which has longitudinally successively arranged pipe sections.
  • the pipe sections are each formed by a tubbing ring, which are aligned with their frontal ring surfaces in a ring groove to each other.
  • each individual tubing ring in the circumferential direction with their end faces lined up tubbings, which each form a butt joint between two of their end faces.
  • a deformable compliance element is arranged.
  • At least one of the tubbings together with the compliance element forms a common prefabricated element, which is formed from a reinforcing mesh of steel surrounded by concrete, to which the compliance element is non-positively connected.
  • the outer cross-sectional contour of the compliance element parallel to the butt joint in this case corresponds to the outer contours of the end faces, whereby the compliant element covers at least one of the two end faces of the tubbings over the entire surface.
  • the compliance element has a respective one towards the annular surfaces of the tubbing ring Recess for a seal on.
  • This recess extends in each case over the sides of the compliance element between the two end faces of the tubbings and forms in cross section a substantially half circular area.
  • This design can basically also be used in the adjustment.
  • the sealing effect achieved ensures the shape of the recess for a safe and positionally accurate positioning of a sealing cord within the annular joint, which is maintained even with possible displacements of the tubbing rings with each other in the plane of the annular surfaces.
  • the tubbing itself have at their end faces corresponding seals, which thereby seal directly against each other or against components located in the butt joint.
  • these can be combined directly with a seal that overlaps the respective element from the outer circumference.
  • the elements are already sealed in themselves.
  • the particular advantage lies in the frictional connection of the compliance element with the statically necessary and / or constructive reinforcement of one of the tubbings, whereby an easily stealver,de basic shape is created, which is directly incorporated into the shaping concreting of prefabricated tubbing.
  • the compliance element may be made of different materials such as plastic, it is advantageously made of a refractory, age resistant material such as metal. In addition to various alloys, these can also have a surface protection such as zinc.
  • a preferred embodiment of the invention provides that the compliance element essentially forms a box profile, which has transversal hollow chambers arranged transversely to the circumferential direction of the respective tubbing ring.
  • the box shape results in a compact and easy-to-integrate design that forms a virtually self-contained unit.
  • the advantage of the clear design lies in the simple and the butt joint filling integration of the compliance element in the tubbing expansion.
  • the positive connection to adjacent tubbing rings reduces the cost of a waterproof design to a minimum.
  • the continuous hollow chambers "sacrifice" the plastic deformation of the compliance element due to rock pressure by reducing their volume by controlled compression in one direction. On the size and the sum of the hollow chambers can thus be taken in advance on the influence of the subsequent form of compliance.
  • the hollow chambers in the tunnel longitudinal direction extend radially in an advantageous manner, so that the hollow chambers are visible from the inside of the tubbing removal.
  • the advantage lies in particular in a later introduction of, for example, elastically or plastically deformable materials and components in the hollow chambers and a Tübbings same property stiffening by filling with concrete.
  • the hollow chambers are formed by a plurality of mutually parallel webs, each extending between two opposite and parallel to the end faces of the tubbing longitudinal walls and two each extending in the plane of the annular surfaces of the tubbing rings Transverse walls extend.
  • the individual webs are here crossed at right angles to each other, so that there is a grid structure.
  • the advantage here is in an increased at the beginning of the pressure load resistance, since the individual webs first their In the longitudinal direction to be loaded and "buckling" need to produce a plastic deformation.
  • the longitudinal walls of the compliance element are curved parallel to the longitudinal axis of the tubbing ring to each other inwardly into the interior of the box profile.
  • the longitudinal walls of the compliance element designed in this way have full-surface contact with the adjacent shape-adapted front sides of the tubbings. Due to the biconcave mutually extending shape of the longitudinal walls and in each planoconvex shaped end faces of the tubing, there is the possibility that only one side of the compliance element has a solid bond with one of the end faces of the tubbings, while the opposite side only in conformal contact with the front page the other tubbing stands.
  • a further advantageous embodiment provides that the two longitudinal walls of the compliance element are each formed from a side cheek, wherein the side cheek is a hollow profile whose cross-sectional shape has a circular segment.
  • the circular segment lies here with its circular arc in each case in the likewise form-adapted end faces of the tubbings. Due to the respective plano-convex shape of the longitudinal walls, the previously described advantages of a joint effect in the case of a one-sided composite of the compliance element with one of the tubbings as well as an improved transmission of the shear forces also result here.
  • the execution of the longitudinal walls as a hollow profile also causes a simpler manufacture of Webs produced in the interior grid structure, since the hollow profiles used on the opposite side of the circular arc each have a parallel to the webs extending straight surface, between which extend the transverse webs and can end straight.
  • the invention provides that the compliance element has two opposing parallel and parallel to the two end faces of the tubbing extending longitudinal walls and the intermediate hollow chambers are formed from individual tubular bodies.
  • the tubular bodies are in each case arranged in a row parallel to the longitudinal walls and are in peripheral contact with each other. Between two adjacent rows of tubular bodies, at least one intermediate web is additionally arranged, on which the individual tubular bodies are fixed in their respective position. Due to the round cross-sectional shape of the tubular body results at the beginning relative to the grid structure, a slightly lower resistance, since the lateral surfaces of the tubular body are claimed directly to bending.
  • the tube bodies in a row can also have a spacing of the lateral surfaces which corresponds, for example, to the radius, as a result of which the compliance of the tube cross-section extends contactlessly with one another up to its planar deformation.
  • the lateral surfaces are supported against each other, so that the respective deformation must be made in the interior of the pipe cross-section, resulting in an increased resistance.
  • the resistance of the compliance element can be specifically "adjust" to adapt it to the respective requirements.
  • the filling of the cavities within and between the tubular bodies is analogous to the grid structure applicable.
  • an adjusting element is arranged in the butt joint between the end faces of the tubbings, whereby a bewirkter by the adjustment distance of the end faces is mutually variable. Even if the adjustment outside of lying between the adjacent butt joints gap, for example, in the tubbing or generally next to the Ring plane can be arranged and coupled via a suitable connection with the tubbings, the arrangement of the adjusting element according to the invention in the circumferential plane of the individual ring sections is preferred. This results in a compact closed system, within which the occurring ring forces are passed through statically advantageous. Moreover, the integration of the adjusting element within the tubbing rings effects the best possible utilization of the inner volume created by the tubbing removal.
  • the compliance element is a compressible part of the aforementioned adjustment element or is combined with it within the individual tubbing rings.
  • the combination within a component increases the degree of prefabrication and allows for a uniform production method.
  • a preferred embodiment of the segmental lining provides that the tubbing rings are spatially resiliently connected to each other via a coupling unit.
  • the coupling unit between the tubing rings and other pipe sections here is a detachable connection: This ensures that the different "breathing" in the form of circumferential changes of the tubing rings allows each other and can be largely stress-free, since adjacent tubbing rings thus different Diameter can be taken without being prevented by a rigid composite with adjacent tubbing rings it. Overall, the individual segments are thus safely and accurately positioned with each other at the same time spatial freedom of movement.
  • a further embodiment of the invention provides that the seal is formed from a solid material or a radially flexible hose which can be filled with different media.
  • a medium into the interior of the hose, an elastic cross-sectional change of the hose seal is effected, which achieves its sealing effect even in the absence of or only low contact pressure within the annular joint, by itself generates the necessary contact pressure by volume increase.
  • a valve which can be reached from the inside of the segmental lining and which creates a connection to the interior of the seal as a branch line can also be used to fill and press the seal in retrospect.
  • gaseous media it is also possible, for example, to introduce permanently elastic or hardening materials into the seal.
  • the hose seal for this purpose is equipped with a second spur line through which a located within the seal and displaced during the repressing medium can escape.
  • the tubbing expansion according to the invention thus meets the highest demands on modern and flexible single-shell interior design.
  • a spatially flexible coupling of two adjacent ring sections with each other a good accessibility and a problem-free subsequent replacement of the coupling unit or parts thereof is given.
  • an adjustment element or a compliance element or a combination of the two it is ensured by the spatially flexible coupling that the different "breathing" in the form of circumferential changes of the individual ring sections with each other is possible and can also run largely stress-free.
  • This allows the adjacent ring sections different Diameter, without being prevented by a rigid composite with adjacent ring sections of it. Overall, the individual segments are thus safely and accurately positioned with each other at the same time spatial freedom of movement.
  • each of the ring sections Due to the possibility of a circumference actively actively adaptable design of each of the ring sections results in practical use each individual value, which generates a simplified handling and a significantly increased scope for design. Overall, the installation is facilitated and sometimes accelerated because each coupling unit of the ring sections is easy to reach and the otherwise rigid shape of the inner shell can be easily and safely adjusted. Due to the combination with passive compliance elements and spatially flexible coupling units, the person skilled in the art now has an adaptable and high-performance modular system for the modern interior finishing of underground structures, in particular of tunnels and shafts.
