Definitions

  • the invention relates to the construction of insensitive to explosions in the tunnel interior tunnels.
  • the tunnel wall is generally reinforced accordingly.
  • the tunnel wall must be made so thick that the residual cross-section remaining in the interior of the tunnel after an explosion still has sufficient stability. If the tunnel is e.g. from Tübbingen, the individual segments must be made thicker. It makes them heavier and less manageable.
  • the EP 0 296 067 B1 discloses a lightweight sandwich panel for protecting the exterior of buildings from shock and temperature effects.
  • the object of the invention is a tunnel wall, which has a greater explosion protection effect in detonations in the tunnel interior than a conventionally created tunnel wall of the same mass, and a method for producing such a tunnel wall. Regardless of the manufacturing (Ortbeton- or ready-mixed solution) this should be much thinner and easier to produce with the same protective effect, as a conventional monolithic tunnel wall with given exclusively on the increased wall thickness explosion protection effect.
  • An essential feature of the invention is in this case to construct the tunnel wall from the exterior of the tunnel to the interior of the tunnel out of several, but at least two layers, each of which has a different main function.
  • the outermost layer facing the soil material consists of a concrete, preferably a high-strength or ultrahigh-strength concrete, a fiber-reinforced high-strength or ultrahigh-strength concrete or a reinforced concrete.
  • the tray is at least 20 inches thick.
  • At least one further layer joins the outermost layer in the direction of the tunnel interior, which is elastically or inelastically deformable compared to normal concrete. This layer partially absorbs the energy of an explosion and passes the remaining energy over a larger area and a stretched time interval to the outermost layer of the tunnel.
  • the explosion protection layer is for this purpose according to the invention much more compressible than concrete.
  • the explosion protection layer either directly adjoins the outer tray or is separated from it only by a thin surface finishing or blocking layer (e.g., sealing film).
  • the explosion protection layer has a lower density compared to conventional concrete.
  • a layer is preferably a gas-containing and thus more easily compressible solid suitable.
  • a solid would be aerated concrete, for example.
  • Another preferred material for the energy absorbing layer is polymer concrete.
  • Polymer concrete is particularly well suited because it is both deformable and compressible at low cost and also has a waterproof effect.
  • Another preferred material for the energy absorbing layer is dense foam having a density of more than 100 kilograms per cubic meter.
  • Such hard foam has a low density, is inexpensive and sufficiently compressible for the inventive purpose.
  • the explosion protection layer is due to the good interchangeability after a damage, preferably segmentally composed of standard segments.
  • the thickness of the explosion protection layer is preferably between 2 and 30 centimeters. Surprisingly, even layer thicknesses of a few centimeters are sufficient to ensure explosion protection for the carrier shell even for a particularly dangerous internal explosion, such as the explosion in a tunnel, for terrorist explosives fired at a distance from the tunnel wall (for example in a motor vehicle).
  • the layer must be at least 5% elastic or inelastically compressible at 1000 bar (static), but less than 90%.
  • the explosion protection layer may also be a product produced with a defined computationally optimized structure, which may be e.g. honeycomb structure, like some crumple zones of an automobile.
  • the explosion protection layer is preferred in the case of a tunnel with Ortbetonau touchschale later added as a prefabricated plate via conventional connecting means.
  • the deformability of the plates makes it possible to compensate for tolerances of the mold during their manufacture. With easily deformable material even flat plates can be adapted to the curved tunnel wall. For a material that can not bend sufficiently in the desired thickness, the layer is then preferably achieved by several superimposed thinner plates.
  • An explosion protection layer can also be used e.g. as shotcrete are subsequently applied to the inside of the tray. This can be done by spraying or foaming.
  • the explosion protection layer can be retrofitted as in an in-situ reinforced tunnel.
  • the use of tubbing segments which already carry the explosion protection layer during installation is preferred even during the production of the tunnel. This can be glued / molded in the manufacture of the segments or be after curing, but even before installation, the tubule attached (glued / screwed / anchored / attached with Velcro).
  • An easily replaceable explosion protection layer makes tunnel maintenance easy after an explosion.
  • the explosion protection layer is milled off / sawed / cut off by known erosive measures down to the supporting outer shell (also possible with high-pressure cutting jet) and then replaced (possibly together with an additional thin surface-finishing or water-barrier layer).
  • the explosion protection layer may also be incorporated into a cavity formed by a wall (e.g., fire barrier wall) supported by posts / spacers spaced from the tray.
  • the supports / spacers are preferably designed to yield / compressible when force.
  • This wall has closable filling openings, through which compressible, explosive dissipating material is subsequently filled.
  • the material then does not necessarily have its own dimensional stability, but may also be fluid.
  • a simple and cheap design is sand.
  • Another is sintered recycled plastic, which is pressed through the openings in the still soft state.
  • Another possibility is to produce the cavity by means of a lost formwork without supports / spacers, when the filling material exerts an adhesive effect on the lost formwork and the trayshell surface by keeping the permanent formwork spaced from the trayshell surface, then backfilled with the adhesive explosion protection material and after completion of the filling process and sufficient adhesive action, the brackets of the lost formwork are removed.
  • the energy-absorbing layer often has an unfavorable fire behavior.
  • an upstream fire protection layer facing the interior of the tunnel can therefore additionally protect the energy-absorbing explosion protection layer against the effects of fire from inside the tunnel.
  • the fire protection layer may consist, for example, of fire protection concrete, a fire protection coating or fire protection plates.
  • the fire-resistant concrete may be, for example, reinforced concrete or a fiber concrete in which e.g. Polymer fibers are included. Other fiber types such as flax or glass fibers are conceivable.
