  • the supporting inner shell in the longitudinal direction one behind the other arranged tubular ring sections, which sometimes consist of individual segments, for example, individual tubbing.
  • the advantage lies in a process-safe and with high dimensional accuracy associated prefabrication of the required components, which can be introduced with a continuous propulsion speed.
  • 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 invention is therefore an object of the invention to provide an underground construction as a tubular inner shell of a tunnel or shaft, the limited deformability allowed to nondestructively adapt to the respective requirements and movements of the surrounding soil and rock.
  • the invention provides an underground construction as a tubular inner shell of a tunnel or shaft, which has in its longitudinal direction successively arranged ring sections.
  • the individual ring sections are each aligned with their frontal ring surfaces in a ring groove to each other.
  • at least two adjacent ring sections are connected to one another in a spatially yielding manner by a coupling unit.
  • This provides a spatial compliance of the subterranean expansion, which can thus be adapted to the respective movements of the surrounding soil and rock non-destructive. Due to the gained freedom of movement between the individual ring sections these tension-free change their position to each other, with simultaneous correct positioning with each other. Due to the limited flexibility, a more economical dimensioning of the individual expansion elements is given, since the deformation loads occurring within the connections and the anchor points required for this purpose are significantly reduced.
  • the coupling unit is a detachable connection having at least one releasable connection means.
  • the connecting means is accessible from an inner side of the ring sections and thus from the interior of the underground construction.

  • the anvils themselves have a fixed or releasable bond with one of the ring sections.
  • a further advantageous embodiment provides that the coupling element between the abutments to be connected is a ring component arranged parallel to the course of the inner side.
  • the individual counter bearings are formed here by anchor pins or clamping plates.
  • the coupling element can have different configurations and shapes, such as polygonal or oval, the circular shape is preferred according to the invention.

This ensures that at least all adjacent structural components of the underground construction experience a coupling with each other. As a result, an undesirable unfolding of the annular joint is avoided within non-coupled portions, which also increases the stability of the overall construction.
  • an adjusting element between the end faces of the tubbings is arranged, whereby a bewirkter by the adjustment distance of the end faces of the tubbings is mutually variable.
  • the adjusting element outside the butt joint lying between the adjacent butt joints can be arranged for example in the tubbing or generally adjacent to the ring plane and is coupled via a suitable connection with the tubbing, 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 ring forces occurring static be passed through advantageous.
  • the integration of the adjusting element within the ring plane brings about the best possible utilization of the inner volume created by the segmental lining.
  • a preferred embodiment provides that a compressible yielding element is disposed in the butt joint between the end faces of the tubbing, whereby bewirked by the compliance element distance between the end faces of the tubbings to each other by the elastic or plastic compression of the Yield element is reducible.
  • the advantage lies in a passive circumferential adaptability of the ring sections to possible subsidence of the surrounding soil or mountains. These movements usually begin after the tunnel tube has been driven in and cause the rock formations surrounding the pipe to be compressed. This process can take place at different speeds and last up to several months.
  • the ring sections avoid the additional loads that occur while allowing a rearrangement of the forces in the surrounding soil and rock. In this way, the tubbings can be dimensioned much more economically, since they do not have to absorb the full, established by subsidence and other convergences mountain pressure.

In addition to possibly pending groundwater, this is to be provided in principle for all versions below the water surface. Even if the seal composed, for example, of individual sections can develop their sealing effect, advantageously a one-piece circular solid rubber seal is used for this purpose.
  • the pressing pressure within the annular joint by the coupling of the ring sections with each other is sufficient to achieve the necessary degree of tightness. About a circumferentially arranged within the annular surfaces of the annular groove and the respective movements of the ring sections with each other are securely taken by deformations and registration of the seal.
  • 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 By introducing 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 or low contact pressure within the annular joint, by itself generates the necessary contact pressure by volume increase.

  • 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, via which a located within the seal and displaced during repressing medium can escape.
  • the underground construction according to the invention thus meets the highest requirements for a modern and flexible single-shell interior design.

  • 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.
  • the adjacent ring sections can assume different diameters, without being prevented by a rigid composite with adjacent ring sections.
  • the individual segments are thus safely and accurately positioned with each other at the same time spatial freedom of movement.

Abstract

L'invention concerne un soutènement souterrain en tant que paroi intérieure tubulaire d'un tunnel ou d'un puits, qui comporte des tronçons annulaires (2) placés les uns derrière les autres en direction longitudinale et respectivement alignés les uns par rapport aux autres avec leurs surfaces annulaires frontales (7) dans un joint annulaire (3). Selon l'invention, deux tronçons annulaires voisins (2) sont reliés l'un à l'autre de façon élastique dans l'espace par une unité d'accouplement (11a, 11b, 11c, 11d, 11e, 11f).
