Abstract

The invention relates to a sealing device consisting of two contiguous building elements made of concrete, steel, reinforced concrete, cast iron or other materials, and a shaped sealing element made of an elastomer material which is inserted into a recess and bridges the gap between the building elements in a sealing manner. The building elements are in particular segments which are assembled into a tube-like tunnel such that transverse and longitudinal joints are formed. Each segment has a recess which runs around all bearing surfaces and has two outer side faces and a base side. A rod-shaped sealing element is positioned in the recess. According to the invention the recess within the central area of its base side has a support for the shaped sealing element such that two parallel recesses are formed. Each recess has an outer side face, an inner side face and a base side and a shaped body is housed in each recess. These two shaped bodies are joined to each other by means of a shaped body situated above the support.

Description

Die Erfindung betrifft eine Dichtanordnung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a sealing arrangement according to the preamble of claim 1.

Eine gattungsgemäße Dichtanordnung ist beispielsweise aus der US-A-4 946 309 bekannt. Infolge des Zusammenpressens der aneinanderstoßenden Bauteile bzw. Segmente unter Verringerung des Abstandes des Spaltes bzw. der Quer- und Längsfugen entfaltet dann das Dichtprofil aus elastomerem Werkstoff unter der Wechselwirkung von Kraft und Reaktionskraft seine Dichtleistung. Derartige Kompressionsdichtungen haben sich bei zahlreichen Tunnelprojekten bewährt. Weitere Dichtanordnungen sind etwa aus US 2 798 373 A oder DE 17 08 690A bekannt. A generic sealing arrangement is for example from the US-A-4 946 309 known. As a result of the compression of the abutting components or segments while reducing the distance the gap or the transverse and longitudinal joints then unfolds the sealing profile elastomeric material under the interaction of force and reaction force its sealing performance. Such compression seals have been found in numerous Proven tunnel projects. Other sealing arrangements are about US 2 798 373 A or DE 17 08 690A known.

Ausgehend von dem eingangs geschilderten Stand der Technik besteht nun die Aufgabe darin, eine Dichtanordnung bereitzustellen, die insbesondere bei großen Versätzen der aneinanderstoßenden Bauteile bzw. Segmente für eine dauerhafte Dichtwirkung geeignet ist.Starting from the prior art described at the beginning, there is now the The task is to provide a sealing arrangement that is particularly useful for large Offset the abutting components or segments for a permanent Sealing effect is suitable.

Gelöst wird diese Aufgabe durch die Merkmale des Anspruchs 1.This object is achieved by the features of claim 1.

Die zweckmäßigen Ausgestaltungen der erfindungsgemäßen Dichtanordnung sind:

  • Die beiden parallel verlaufenden Aussparungen sind spiegelsymmetrisch zueinander angeordnet.
  • Die Stirnseite der Abstützung liegt tiefer als die Stoßseite des Bauteiles bzw. Segmentes, und zwar unter Bildung einer stirnseitigen Aussparung.
  • Die beiden in den parallel verlaufenden Aussparungen einsitzenden Profilkörper sind geometriegleich, wobei ferner die insgesamt drei Profilkörper einen einstückigen Gesamtverbund bilden, und zwar vorzugsweise unter Bildung einer gemeinsamen ebenflächigen Profilstirnseite. Außerdem ist es vorteilhaft, wenn innerhalb der drei Profilkörper eine Rillennut und/oder zwei Rillennuten vorhanden sind.
  • Die Außen- und Innenflanken der beiden parallel verlaufenden Aussparungen verlaufen schräg, und zwar unter Verbreiterung der beiden Aussparungen zur Stoßseite des Bauteiles bzw. Segmentes hin.
  • Die Querschnittsfläche der Abstützung ist kleiner als die Querschnittsfläche der gesamten Aussparung, die aus den beiden parallel verlaufenden Aussparungen sowie gegebenenfalls aus der stirnseitigen Aussparung gebildet ist. Insbesondere wiederum ist die Querschnittsfläche der Abstützung kleiner als die Querschnittsfläche jeder der beiden parallel verlaufenden Aussparungen.
  • Die Abstützung umläuft das Bauteil bzw. das Segment vollständig.
The expedient configurations of the sealing arrangement according to the invention are:
  • The two parallel recesses are arranged mirror-symmetrically to each other.
  • The end face of the support is lower than the abutment side of the component or segment, with the formation of an end recess.
  • The two profile bodies seated in the parallel recesses are of the same geometry, and further the three profile bodies form an integral overall assembly, preferably with the formation of a common flat profile end face. It is also advantageous if a groove and / or two groove grooves are present within the three profile bodies.
  • The outer and inner flanks of the two parallel cutouts run obliquely, widening the two cutouts towards the butt side of the component or segment.
  • The cross-sectional area of the support is smaller than the cross-sectional area of the entire recess, which is formed from the two parallel recesses and optionally from the front recess. In particular, the cross-sectional area of the support is in turn smaller than the cross-sectional area of each of the two parallel cutouts.
  • The support completely runs around the component or segment.
