Definitions

  • the invention relates to a sealing arrangement for shaft and tunnel structures.
  • Each body which is composed of individual monolithic components, has contact joints. This applies, for example, to shaft and tunnel structures, which consist of prefabricated parts (Tubbingen). Should e.g. a tunnel under the groundwater level is created and used, this results in the need for waterproofness of the entire structure. For a building of a variety of prefabricated items arises from this not only the demand for the water resistance of the monolithic components, but also after the sealing of the contact joints between the components against the hydrostatic pressure.
  • Sealing arrangements for sealing constructive joints in tunnel structures which are made of prefabricated components (Tubbingen) are basically known, see for example the DE 102005039253 . DE 102005039056 . US 4946309 . EP 0222968 . EP 0441250 . EP 0995013 and US5044823 , which is provided as the closest prior art.
  • a sealing element is glued into a groove which rotates at a constant distance from the outer surface of the tubbing around the butt sides.
  • the sealing effect of the sealing system is achieved by joining the tubbing in that the sealing elements in the joints touch each other mirror-symmetrically.
  • the contact must be made at least with a surface pressure that is above the Pressure in the upcoming print medium is.
  • the desired surface pressure is set by the choice of the elastic compression behavior of the two sealing elements in dependence on the way of the compression.
  • the known sealing arrangements have numerous disadvantages. For example, when choosing an incompressible elastomer as the material for the sealing elements, the pressing force in the sealing arrangement can increase enormously. In extreme cases, damage to the sealing arrangement as well as to the environment can not be ruled out in the transmission of the associated reaction forces in the component. This leads in particular to the local encounter of several components with the corner bodies of their sealing systems to leaks or damage.
  • the mirror-symmetrical arrangement of the sealing elements remains practically a coincidence.
  • the contact of the two sealing elements then takes place only on a reduced support share. Since the surface pressure is not independent of this percentage of support, the risk of leakage increases with reduced pressure.
  • the sealing elements in the contact joints of the tunnel should have an unlimited lifetime as far as possible.
  • the technical requirement is defined as 100 years lifetime.
  • the property of relaxation of the material must be considered.
  • the relaxation of the elastic tension forces (up to 40%) over time must be taken into account by an excessive initial tension in the assembly of the sealing arrangement. All already undesired force reactions of the elastic tension forces are amplified accordingly.
  • the object of the present invention is therefore to improve the sealing of joints between components of manhole and tunnel structures, so that the disadvantages of the prior art are avoided, and in particular for a long service life a reliable seal of manhole and tunnel structures in different density situations and Sealing phases is achieved.
  • the sealing elements of the sealing system are formed in their geometry such that they have after mutual contact pressure surfaces against a low pressure or the atmosphere. Due to the pressure difference between the media, a differential pressure acts on these pressure surfaces, resulting in the force which ensures the required surface pressure on the surface with which the sealing elements lie against one another at the contact plane.
  • the pressing pressure is inevitably always adapted to the respective media pressure and is essentially independent of the joint width which is established after the contact.
  • significantly lower reaction forces are required in the inventive arrangement.
  • the contact pressure can also be adjusted.
  • an offset of the components does not change the quality of the tightness, since the contact does not depend on the symmetry of the sealing elements.
  • the sealing element is pivotable or tiltable about a hinge.
  • a "joint” is understood here as meaning a region of the sealing system which has or forms a rest pole around which the pivoting movement of the sealing element takes place and which itself does not participate in the pivoting movement, at least substantially. In the joint region are by the pivoting or tilting of the Sealing element caused deformation movements relatively small (almost "zero").
  • the joint region may have a reduced cross-section compared to the adjacent base body and / or sealing element and / or a softer material.
  • the joint connects the main body of the sealing system with the sealing element. The pivoting or tilting movement can take place in the direction of the joint or opposite thereto.
  • the force portion of the contact pressure generated by any biasing of the sealing member is greater than the force portion of the contact pressure caused by the media differential pressure, i. the pressure difference between the media is caused as low as possible.
  • the force component of the contact pressure generated by the media differential pressure is> 50%, more preferably> 60%,> 70%,> 80%,> 85% or> 90, particularly preferably> 95%,> 96%,> 97% ,> 98% or> 99%.
  • contact pressure or “surface pressure” is meant herein pressure at the contact surface, i. the surface at which the sealing elements are in contact at the contact plane prevails.
  • a “pressure surface” is understood here as meaning any surface of the sealing system, in particular of the sealing element, which is exposed to the medium pressure.
  • each of the sealing systems has a base body with which the sealing system is fastened to the component.
  • the attachment can be done in many ways, for example by gluing, Einbetontechnik, pressing or with the help of anchoring feet.
  • the elastic sealing system consists of elastomeric material.
  • elastic refers to the property of a body or material to change its shape under the action of force and, in the absence of the acting one Force to return to its original form.

  • each of the sealing systems has at least two projecting to the joint sealing elements, with which the sealing systems abut contact planes.
  • the provision of two, three or more and thus redundant sealing elements ensures increased sealing safety.
  • the sealing systems can be arranged in a groove running around the abutting faces of the components and / or on a chamfer of the components circulating around the abutment faces of the components.
  • the groove or chamfer need not be spaced from the edge of the butt sides of the components, but may be disposed at the edge of the butt sides, the sealing systems in this case being arranged in alignment with the side surfaces of the components. In this way, the otherwise resulting leakage channels are avoided, which must be additionally closed in arrangements according to the prior art with a filling belt.
