Definitions

  • the invention relates to a tubbing removal according to the features in the preamble of claim 1.
  • 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.
  • DE 33 21 777 C2 shows a lining for a tubular underbody cavity to be produced in shield tunneling, such as a traffic tunnel, a pipeline or the like.
  • shield tunneling such as a traffic tunnel, a pipeline or the like.
  • This has in each case between two adjacent tubbing rings, which are formed by made of steel tubbings, circumferential sealing rings.
  • each end face of the individual tubbing rings each includes a groove, wherein two grooves together form a circumferential sealing chamber, in which the sealing ring is inserted.
  • the circumferential sealing ring made of solid material fulfills its sealing task as a self-contained system.
  • the lining does not provide any movement of the individual tubbing rings within the ring joints, as these are firmly connected together.
  • a theoretical reduction of the lining between the annular joints causes a minimal spread of the end faces equipped with the grooves by an angle change to each other, which is easily compensated by the elastic sealing ring.
  • a transfer of the solution to one equipped with more freedom of movement Expansion quickly reaches its limits, since the elastic deformability while maintaining the contact pressure necessary for sealing is only slight.
  • DE 38 15 142 A1 discloses an activatable seal, which shows a composite of four profile bands sealing frame, which is arranged around the respective edge region of each individual tubbing around. The edge regions have corresponding recesses for this, in which the seal is inserted and initially flush with the outer dimensions of the corresponding tubbing completes.
  • the sealing frame is increased in retrospect by an injected medium in its volume, so that only later uses the sealing effect.
  • the described seal meets the requirements for an activatable and assembly-facilitating sealing system. Although it allows for a limited increase in the contact pressure, if necessary, but this does not ensure adequate sealing effect with larger movements and increased gap masses.
  • this solution comes up against its limits, since the individual pressed against each other sealing frame so to speak "slide" past each other and so the system effect is repealed.
  • the predominantly rectangular cross-sectional geometry of the profiled strips leaves little room for deformation and is therefore designed more for static systems.
  • the work on the various injection channels is quite confusing dar.
  • each of the four corner areas of each tubbing is at the intersection of four coincident separate sealing frame of several tubbings in movements with each other, the increased risk of possible leakage.
  • the solution described in both the production and in the installation phase and activation phase is considered to be expensive and expensive.
  • the invention thus has the object, a tubbing expansion as a tubular inner shell of a tunnel or shaft to create, which has flexibly adjustable between his tubing rings and cost-effective and easy-to-use sealing organs, which cause an improved sealing effect even with possible deformations and displacements of the tubbing rings.
  • the invention provides a tubbing removal as a tubular inner shell of a tunnel or shaft, which has in its longitudinal direction one behind the other arranged tubbing rings.
  • the individual tubing rings are each aligned with their frontal ring surfaces in a ring groove to each other.
  • the tubbing rings are in this case formed in each case in the circumferential direction juxtaposed tubbing segments, which each form a butt joint between their adjacent end faces.
  • the invention provides that in at least one annular joint between two tubbing rings a circumferential annular seal which can be varied in cross-section is arranged.
  • the annular surfaces are securely sealed to each other against possible ingress of surrounding water. Even if the seal composed, for example, of individual sections can develop their sealing effect, a major advantage of the invention lies in the one-piece, which in addition to easier handling especially no sources of error and dangers due to the fragmentation of self-contained sealing system. Moreover, the closed roundness is characterized by a permanently insensitive and its sealing effect retaining ability of adaptation in all occurring deformations and displacements. Due to the variable cross-section is the Ring seal easily adaptable to different or changing joint widths.
  • the variability of the cross section can be used here already in the installation phase by a cross-sectional reduction in order to ensure an unhindered coupling of the tubbing rings with each other, which otherwise takes place against the elastic deformation resistance of the seal.
  • the subsequent enlargement of the cross section represents a particular advantage, since the ring seal can be adapted at any time, for example, to a changing width of the annular joint.
  • the invention provides that the ring seal is a self-contained hose. This is for the necessary variability of the cross section, at least in its cross-sectional shape elastically extensible and malleable, so that a permanent adaptation to the changes of the annular joint is ensured.
  • the hollow shape of the tube contributes to weight reduction, which offers particular advantages in handling, especially during the installation phase over the entire circumference of the annular surface.
  • the deformability over a cross-section made of solid material is substantially increased.
  • a further embodiment of the invention provides that the ring seal can be filled with different media via at least one connection.
  • a medium into the interior of the tube, a radially elastic change in cross section of the ring seal is effected, which thus achieves its sealing effect even in the absence of or only low contact pressure within the annulus by itself generates the necessary contact pressure by volume growth.
  • the connection may be cross-linked to other ring seals or may be extended to a central location via a suitable guide, it is considered to be particularly advantageous if it is formed by a valve to be reached from the inside of the subterranean structure as stub line one Connection to the interior of the seal creates.
  • connection can be done at any time emptying and filling and pressing the ring seal.
  • permanently elastic or thermosetting materials can be introduced into the ring seal.
  • this is provided for this purpose with a second connection, via which a medium located within the seal and displaced during the re-pressing exit or generally, for example, air can escape during filling.
  • the invention provides that at least one of the end-face annular surfaces between the opposing tubbing rings has a circumferential annular groove in which the annular seal is arranged.
  • the ring seal is inserted and fixed in its annular groove, so that the preparation of the next in the longitudinal direction of the tubbing segment tubbing ring can be done.
  • the possible deformation of the ring seal is structurally limited, which takes place by the relative movement of the opposite end faces to each other.
  • the circumferential annular groove also causes mechanical protection of the ring seal from influences, for example by penetrating material in the annular joint, which ensures their lasting action.
  • the annular groove contributes to the preservation of the sealing effect, since it basically remains between the end-side annular surfaces within the annular gap and can not "roll out” of the cross-sectional plane of the tubbing removal.
  • the invention also provides that two frontally opposite annular surfaces between the tubbing rings each have a circumferential annular groove, which form a closed sealing chamber when merging both annular surfaces.
  • the advantage lies in a symmetrical production of individual tubbings with respect to their edge regions as sub-segments of the annular surfaces of the tubbing rings.
  • the stub in combination with the connection for media filling of the hose in this case the stub can be placed exactly in the middle of the annular joint.
  • portions of the ring seal may also go beyond the ring gap, the ring gap always maintains its positioning relative to the ring seal.
  • 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 occurring ring forces are passed through statically advantageous.
  • the integration of the adjusting element within the tubbing rings effects the best possible utilization of the inner volume created by the tubbing removal.
  • 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 tubbing rings to possible subsidence of the surrounding earth or mountain. These movements are usually after driving up the tunnel tube and cause a compression of the pipe enclosing Rock formations. This process can take place at different speeds and last up to several months.
  • the tubbing rings 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.
  • 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 tubbing rings and other pipe sections is in this case 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 can thus assume different diameters without being hindered by a rigid composite with adjacent tubbing rings to become. Overall, the individual segments are thus safely and accurately positioned with each other at the same time spatial freedom of movement.
  • the tubbing expansion according to the invention thus meets the highest demands on modern and flexible single-shell interior design.
  • the ring seal used is characterized not only by the permanently insensitive and its sealing effect retaining ability of adaptation to deformations and displacements mainly by the easy handling in combination with the variability of their cross-sectional shape, so they can be easily adapted to different or changing widths of the annular joint at any time.
