Definitions

  • the present invention relates to a building structure according to The preamble of claim 1, a method for lining a overhanging natural ground wall section according to the preamble of Claim 10 and use of the method.
  • CH-A-560 811 describes a method for sealing Walls of engineering structures made of concrete, in which one a 1 to 30 mm thick on the raw surface of the building Applying a layer of an elastic bitumen elastomer adhesive, a plastic film with this adhesive layer under the influence of heat fully glued and then the film with another 1 to 10 mm thick layer of an elastic material for protection against mechanical damage.
  • Fig. 1 is a tunnel structure commonly used today based on a cross section through a tunnel tube shown.
  • a first layer 5 is applied to the tunnel tube.
  • she is either by means of a formwork with segments and repeated Backfilling mortar or created as a shotcrete layer.
  • this layer 5 there is a sealing layer 7 made of plastic, in the form of welded, prefabricated film sections made of polyethylene or soft PVC. So in the future emerging leaks, in a limited surface area, localized and a corresponding re-sealing made can be, is the sealing layer formed as a film 7 divided into partitioned zones.
  • the actual load-bearing layer 9 follows Shells and backfills are formed, the respective according to static requirements, with steel reinforcement armored.
  • the building structure according to the invention is concerned preferably and according to claim 9, a tunnel structure, and following the wording of claim 15 the mentioned method preferably for the lining of Tunnel tubes used.
  • the first layer will - analogous to 5 of FIG. 1 - preferably essentially Shotcrete formed and the sealing layer - analogous to 7 of Fig. 1 - provided between the first and the second layer.
  • a sealing layer continues on the first layer - analogous to 5 of FIG. 1 - clawed in that the latter mentioned on the surface Layer profiles are formed, preferably with a density that meets the respective stress requirements corresponds.
  • sealing layer is provided embedded granules, preferably in the form of grit, with which an optimal anchoring profile is realized for an outward-connecting layer, such as in particular for the second layer - analogous to 9 of FIG. 1.
  • the sealing layer as a sprayed Foil formed, for example from a polyurethane reaction resin. It is either directly on the natural ground, the inherent surface profiling directly as claw profiling acts, or on an analogy to shift 5 of Fig. 1 formed first layer sprayed.
  • the sealing layer can be sprayed become, which is much less expensive than the known Foil application.
  • the entire layer composite can, due to the positive Clawing, absorbing shear stresses.
  • the resultant due to the clawing according to the invention Possibility to spray the layers mentioned, for example Manufacturing from shotcrete leaves the problem no longer regarding concrete compaction in the crown area come up.
  • the further resulting from the clawing according to the invention Possibility to spray all layers of the cladding realizing enables a continuous Feed with far less problematic material replenishment.
  • the Cladding local widening and narrowing as well Cladding tubes with smaller radii of curvature is no problem.
  • a first layer 5a is deposited, which is preferably made of shotcrete. Shortly before the end of the The molding process is profiled by mechanical intervention worked into the surface of layer 5a or through special spray technology, e.g. by spraying with saccaded Feed. The profiling is formed by knobs, Bars, grooves, etc.
  • the sealing layer 7a is sprayed on, for example by Use of a reactive polyurethane resin.
  • the film-like Layer 7a practically forms the profiling of surface 15 1: 1 to the outside.
  • the sealing layer 7a preferably again by concrete spraying, the Layer 9a applied, which with the layer 7a the layer 5a claws thanks to their surface profile.
  • a layer composite is thus created, which is also in the zone of the sealing layer 7a due to the claw in same mass as the layers 5a and 9a shear stresses can record.
  • anchors 17 can be used if desired anchoring layer 9a and / or layer 5a be realized with the natural ground.
  • FIG. 3 shows a further building structure according to the invention.
  • Spraying onto the natural ground surface 1 applied a relatively thick sealing layer 7b, which the inherent profiling of the natural surface 1 clawed.
  • a polymer concrete is used for this purpose, for example.
  • the surface is initially exposed the sealing layer 7b, as with reference to FIG. 2a with respect to the Layer 5a has been explained, preferably by mechanical intervention with a given density, profiled, be it through Knobs and / or channels and / or grooves and / or notches etc.
  • the layer 9a is applied directly to the sealing layer 7b, preferably again by concrete spraying, and clawed the profile at 17 with the sealing layer 7b.
  • anchors 17a are provided, which the Anchor layer 9a to the natural subsurface and thus also its Make more use of load capacity.
  • one of the at least two layers to be provided are used directly as a sealing layer. On the one hand, it is due to the inherent profiling anchored, on the other hand there is a Profiling 17 provided, followed by the subsequent Layer 9a claws.
  • the relatively thick sealing layer there 7b to a film-like, thin sealing layer 7c which is sprayed directly onto the micro- and macro-profiled natural surface 1 sprayed becomes.
  • the layer 9a is applied directly to the sealing layer 7c, again preferably applied by concrete spraying and claws over layer 7c with the inherent surfaces inherent Profilings. If necessary, the Layer 9a in turn anchored to the natural ground by means of anchors 17b become.
  • FIG. 4a in FIG. 4b and FIG. 2a in FIG. 2b further preferred embodiments of the sealing layer 7c or 7a sprayed on in the form of a film are shown.
  • granules 19c or 19a are embedded in the layer material, preferably grit.
  • FIG. 3 it is also possible, with a view of FIG. 3, to realize the profiling 17 shown there, as shown at 19b, in that, before the spray application for the layer 7b is completed, a layer of granules, preferably a grit, into the still soft plastic mass of the Layer 7b is shot.
  • Fig. 1 results in a smallest radius of curvature Tube cross-section of approx. 5.5 m through the inventive Procedure already in accordance with FIG. 2a a reduction in the cladding thickness D by about 20cm, according to the dashed entry at D '. It goes without saying that starting out of a required opening of a tunnel tube, this says nothing more than that the tube to be broken out can be made correspondingly smaller.
