Definitions
- the invention relates to a sealing profile made of elastomeric material for tunnel segments provided with a circumferential groove, which on its base side has open or closed groove grooves which run in the longitudinal direction and mostly also channels which run in the longitudinal direction.
- the sealing frames of a segment made of concrete, steel, reinforced concrete or cast iron mostly consist of four composite strand-shaped sealing profiles (profiled strips) made of elastomeric material, ie of rubber or rubber-like plastic, whereby the frame corners are preferably produced by the injection molding process.
- the tunnel construction in segmental construction with a special arrangement of the segments. It is often sufficient if each segment has a sealing frame. In special circumstances, however, it may be necessary to provide each segment with a double sealing frame, it being possible for the two parallel sealing frames to be connected to one another with an additional sealing cross profile (EP-A-0 337 177).
- the sealing profiles or sealing frames are usually located in a corresponding groove (groove depth d, groove width w) of the tunnel segment.
- the first sealing profile for tunnel segments was developed in 1968 for the Elbe tunnel in Hamburg, whereby the elastomer profile had four groove grooves.
- the segments were made of cast iron (World Tunneling, 12/1989, page 459, Fig. 6).
- the sealing profiles developed for this were mostly provided with groove grooves and channels (DE-U-78 22 476, DE-C-28 33 345, GB-B-2 178 114, EP-A-0 255 600, EP-A-0 306 796, EP-A-0 368 174, EP-A-0 414 137).
- the sealing profile has only a single holding foot, which is located in the middle of the base side.
- the tunnel segment (1) with the circumferential groove (2; depth d, width w) has an additional circumferential anchoring groove (3; depth d ', width w').
- the sealing profile (4) made of elastomeric material is now inserted into the groove (2), the holding foot (5) according to the invention being clamped or pressed into the anchoring groove (3).
- the sealing profile (4) has two open groove grooves (7, 8) on its base side (6) and three channels (10, 11, 12) towards the profile back (9).
- the holding foot (5) arranged in the middle of the base side (6) is provided with clamping ribs (13, 14).
- the sealing profile can also have closed groove grooves (GB-A-2 017 194, EP-A-0 414 617).
- the frame corners of the holding foot (5) are expediently produced by the injection molding process.

Description
- Die Erfindung betrifft ein Dichtungsprofil aus elastomerem Werkstoff für mit einer umlaufenden Nut versehene Tunnel-Segmente, das an seiner Basisseite in Längsrichtung verlaufende offene oder geschlossene Rillennuten sowie zumeist ebenfalls in Längsrichtung verlaufende Kanäle aufweist.
- Die Dichtungsrahmen eines Segmentes aus Beton, Stahl, Stahlbeton oder Gußeisen bestehen zumeist aus vier zusammengesetzten strangförmigen Dichtungsprofilen (Profilbänder) aus elastomerem Werkstoff, d.h. aus Gummi oder gummiähnlichem Kunststoff, wobei die Rahmenecken vorzugsweise nach dem Injection-Molding-Verfahren hergestellt werden. Von besonderer Bedeutung ist der Tunnelbau in Tübbing-Bauweise mit spezieller Anordnung der Segmente. Häufig genügt es, wenn jedes Segment einen Dichtungsrahmen aufweist. Unter besonderen Umständen kann es jedoch erforderlich werden, jedes Segment mit einem Doppeldichtungsrahmen zu versehen, wobei die beiden parallel verlaufenden Dichtungsrahmen mit einem zusätzlichen Dichtungsquerprofil (EP-A-0 337 177) miteinander verbunden sein können. Die Dichtungsprofile bzw. Dichtungsrahmen befinden sich meistens in einer entsprechenden Nut (Nuttiefe d, Nutbreite w) des Tunnel-Segmentes. Unter Einwirkung einer Kraft verringert sich der Spaltabstand zweier Tunnel-Segmente von So (Abstand im unbelasteten Zustand) auf S₁ (Abstand im belasteten Zustand). Dadurch werden die beiden gegenüberliegenden Elastomerprofile zusammengepreßt, was die Abdichtung des Spaltes zur Folge hat (EP-A-0 441 250, Fig. 1).
- Das erste Dichtungsprofil für Tunnel-Segmente wurde 1968 für den Elbtunnel in Hamburg entwickelt, wobei das Elastomerprofil vier Rillennuten aufwies. Bei diesem weltweit ersten Tunnelprojekt, bei dem Dichtungsprofile zum Einsatz kamen, bestanden die Segmente aus Gußeisen (World Tunnelling, 12/1989, Seite 459, Fig. 6). Bei späteren Tunnelprojekten in Kontinentaleuropa, Asien, Nord- und Südamerika sowie in Nordafrika wurden in zunehmenden Maße Segmente aus Beton eingesetzt. Die hierfür entwickelten Dichtungsprofile waren zumeist mit Rillennuten und Kanälen versehen (DE-U-78 22 476, DE-C-28 33 345, GB-B-2 178 114, EP-A-0 255 600, EP-A-0 306 796, EP-A-0 368 174, EP-A-0 414 137).
- Bislang werden die Dichtungsrahmen innerhalb der Segmentnut verklebt, so daß die Aufgabe der Erfindung nun darin besteht, die Dichtungsprofile ohne Einsatz eines Spezialklebers sicher zu verankern. Gelöst wird diese Aufgabe durch das Kennzeichen des Anspruchs 1.
- Besonders zweckmäßig ist es, wenn das Dichtungsprofil lediglich einen einzigen Haltefuß, der sich in der Mitte der Basisseite befindet, aufweist.
- Die Erfindung wird nun anhand eines Ausführungsbeispiels unter Bezugnahme auf schematische Zeichnungen erläutert. Es zeigen:
- Fig. 1
- Tunnel-Segment und Dichtungsprofil mit dem erfindungsgemäßen Haltefuß;
- Fig. 2
- eine vergrößerte Darstellung des Dichtungsprofils gemäß Fig. 1.
- Nach Fig. 1 weist das Tunnel-Segment (1) mit der umlaufenden Nut (2; Tiefe d, Breite w) eine zusätzliche umlaufende Verankerungsnut (3; Tiefe d', Breite w') auf. In die Nut (2) wird nun das Dichtungsprofil (4) aus elastomerem Werkstoff eingesetzt, wobei der erfindungsgemäße Haltefuß (5) in die Verankerungsnut (3) eingeklemmt bzw. eingedrückt wird.
- Nach Fig. 2 besitzt das Dichtungsprofil (4) an seiner Basisseite (6) zwei offene Rillennuten (7, 8) sowie zum Profilrücken (9) hin drei Kanäle (10, 11, 12). Der in der Mitte der Basisseite (6) angeordnete Haltefuß (5) ist mit Klemmrippen (13, 14) versehen. Im übergangsbereich (15) von Dichtkörper und Haltefuß (5) ist ein weiterer Kanal (16) vorhanden, der im unbelasteten Zustand zu 20 bis 40 % (hier etwa 25 %) seiner Gesamthöhe h in den Haltefuß (5) eintaucht.
- Anstelle der offenen Rillennuten (7, 8) kann das Dichtungsprofil auch geschlossene Rillennuten (GB-A-2 017 194, EP-A-0 414 617) aufweisen.
- Die Rahmenecken des Haltefußes (5) werden zweckmäßigerweise nach dem Injection-Molding-Verfahren hergestellt.
Claims (4)
- Dichtungsprofil (4) aus elastomerem Werkstoff für mit einer umlaufenden Nut (2) versehene Tunnel-Segmente (1), dasa) an seiner Basisseite (6) in Längsrichtung verlaufende offene oder geschlossene Rillennuten (7, 8) sowieb) zumeist ebenfalls in Längsrichtung verlaufende Kanäle (10, 11, 12) aufweist,dadurch gekennzeichnet, daßc) das Dichtungsprofil (4) an seiner Basisseite (6) wenigstens einen in Längsrichtung verlaufenden Haltefuß (5) besitzt, der in einer zusätzlichen umlaufenden Verankerungsnut (3) einsitzt, wobeid) im Übergangsbereich (15) von Dichtkörper und Haltefuß (5) ein längsverlaufender Kanal (16) vorhanden ist, der im unbelasteten Zustand 20 bis 40 % seiner Gesamthöhe h in den Haltefuß (5) eintaucht.
- Dichtungsprofil nach Anspruch 1, dadurch gekennzeichnet, daß ein einziger Haltefuß (5) vorhanden ist, der sich in der Mitte der Basisseite (6) befindet.
- Dichtungsprofil nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß der Haltefuß (5) Klemmrippen (13, 14) aufweist.
