Abstract

A sub-surface tunnel has a lining formed by keystones or shaft lining segments (2,3) separated by gaps (4). Each gap is filled by a two-part rubber seal (7,8). A lubricant (9) is applied to the interface between the sections of rubber seal. After curing, the lubricant (9) forms a cold-vulcanized union between the two halves (7,8) of the seal.

Description

Die Erfindung betrifft eine Dichtanordnung, umfassend wenigstens
The invention relates to a sealing arrangement, comprising at least

  • - zwei aneinanderstoßende Bauteile unter Bildung eines Spaltes;- Two abutting components to form a gap;
  • - einen Dichtkörper aus elastomerem Werkstoff, der den Spalt abdichtend überbrückt; sowie- A sealing body made of elastomeric material, which seals the gap bridged; such as
  • - ein Gleitmittel für die Kontaktflächen zwischen dem jeweiligen Bauteil und dem Dichtkörper, insbesondere für die Kontaktflächen zwischen zwei Dichtkörpern (DE-A-198 26 482).- A lubricant for the contact surfaces between the respective component and the Sealing body, in particular for the contact surfaces between two sealing bodies (DE-A-198 26 482).

Im Rahmen einer Weiterentwicklung zeichnet sich die Dichtanordnung gemäß Kennzeichen des Patentanspruches 1 dadurch aus, dass
As part of a further development, the sealing arrangement according to the characterizing part of patent claim 1 is characterized in that

  • - das Gleitmittel so beschaffen ist, dass es zunächst beim Einbau eine gleitende Funktion aufweist und schließlich nach dem Einbau als kaltvulkanisierendes Klebemittel auftritt.- The lubricant is designed so that it is initially a sliding one when installed Has function and finally after installation as a cold vulcanizing Adhesive occurs.

Durch die Kaltvulkanisation werden Dichtkörper und Bauteile, insbesondere zwei Dichtkörper, dauerhaft miteinander verbunden. Die diesbezüglichen Vorteile treten bei eventuellen Spaltöffnungen auf.The cold vulcanization process seals and components, especially two Sealing body, permanently connected to each other. The related advantages come into play possible stomata.

Zweckmäßige Anwendungsbereiche sind in den Patentansprüchen 2 bis 4 genannt, wobei der Tunnelbau, insbesondere beim Schlusssteineinschub, von herausragender Bedeutung ist.Appropriate areas of application are mentioned in claims 2 to 4, the tunnel construction, especially when inserting keystones, is outstanding Meaning is.

Die Erfindung wird nun anhand eines Ausführungsbeispiels unter Bezugnahme auf eine schematische Zeichnung erläutert. The invention will now be explained using an exemplary embodiment with reference to FIG a schematic drawing explained.  

Die einzige Figur zeigt im Rahmen des Tunnelbaus eine Dichtanordnung 1, die zwei aneinanderstoßende Segmente 2 und 3 aus Beton unter Bildung eines Spaltes 4 umfasst. Jedes dieser Segmente ist mit einer Aussparung 5 und 6 ausgestattet, in der jeweils ein strangförmiger Dichtkörper 7 und 8 aus elastomerem Werkstoff einsitzt. Der Dichtkörper weist üblicherweise Rillennuten und Kanäle auf, wobei hinsichtlich diesbezüglicher Details auf die Offenlegungsschrift DE-A-198 26 482 verwiesen wird.In the course of tunnel construction, the single figure shows a sealing arrangement 1 which comprises two abutting segments 2 and 3 made of concrete to form a gap 4 . Each of these segments is equipped with a recess 5 and 6 , in each of which a strand-shaped sealing body 7 and 8 made of elastomeric material is seated. The sealing body usually has groove grooves and channels, reference being made to the published patent application DE-A-198 26 482 for details in this regard.

Infolge des Zusammenpressens der aneinanderstoßenden Segmente 2 und 3 unter Verringerung des Abstandes des Spaltes 4 entfalten dann die beiden Dichtkörper 7 und 8 unter der Wechselwirkung von Kraft und Reaktionskraft ihre Dichtleistung.As a result of the pressing together of the abutting segments 2 and 3 while reducing the distance between the gap 4 , the two sealing bodies 7 and 8 then develop their sealing performance under the interaction of force and reaction force.

Im Bereich der Kontaktflächen 9 befindet sich nun das Gleitmittel, das so beschaffen ist, dass es zunächst beim Einbau eine gleitende Funktion aufweist und schließlich nach dem Einbau als kaltvulkanisierendes Klebemittel auftritt.In the area of the contact surfaces 9 there is now the lubricant, which is designed such that it initially has a sliding function during installation and finally occurs as a cold-vulcanizing adhesive after installation.

Tritt nun eine Spaltöffnung, d. h. eine Vergrößerung des Abstandes des Spaltes 4 auf, so bleiben die Kontaktflächen 9 der Dichtkörper 7 und 8 durch die Kaltvulkanisation dauerhaft verbunden. If a gap opening now occurs, ie an increase in the distance between the gap 4 , the contact surfaces 9 of the sealing bodies 7 and 8 remain permanently connected by the cold vulcanization.
