Description

Die Erfindung betrifft eine Dichtanordnung gemäß Oberbegriff des Anspruchs 1. Solch eine Anordnung ist aus der GB-A-2 178 114 bekannt.The invention relates to a sealing arrangement according to the preamble of claim 1. Such an arrangement is known from GB-A-2 178 114.

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 Injektion-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 Elastomer-Profile zusammengepreßt, was die Abdichtung des Spaltes zur Folge hat.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, that is, of rubber or rubber-like plastic, the frame corners preferably being produced by the injection molding process. Of particular importance is 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. Under the action of a force, the gap distance between two tunnel segments decreases from S o (distance in the unloaded state) to S₁ (distance in the loaded state). As a result, the two opposite elastomer profiles are pressed together, which results in the sealing of the gap.

Aus der DE-U-74 32 945 ist ein Dichtungsprofil bekannt, das im Querschnitt gesehen von asymmetrischer Gestalt ist, wobei die Asymmetrie dadurch hervorgerufen wird, daß sich zur Segment-Außenseite (Wasserseite) hin eine Aussparung im ebenflächigen Stirnkantenrücken des Profiles befindet. Außerdem weist dieser Stirnkantenrücken eine Stützrippe auf, die sich in einer entsprechenden Nut des Segmentes befindet.From DE-U-74 32 945 a sealing profile is known which, viewed in cross-section, is of asymmetrical shape, the asymmetry being caused by the fact that a recess is located in the flat front edge back of the profile towards the outside of the segment (water side). In addition, this front edge back has a support rib which is located in a corresponding groove in the segment.

Aus der DE-A-31 01 332 ist ein Gummiprofil zum Abdichten von gegeneinander gepreßten Stirnwänden von Tunnel-Segmenten bekannt, das ebenfalls eine asymmetrische Querschnittsgestalt besitzt. Dabei weist dieser Profilkörper eine Dichtlippe auf, die der Außenseite des Tunnel-Segmentes zugekehrt ist, damit der Wasserdruck die Dichtwirkung erhöhen kann. Eine derartige Dichtlippe bezeichnet man in diesem Zusammenhang auch als "druckaktivierende Lippe".From DE-A-31 01 332, a rubber profile for sealing end walls of tunnel segments pressed against one another is known, which also has an asymmetrical cross-sectional shape. This profile body has a sealing lip that faces the outside of the tunnel segment so that the water pressure can increase the sealing effect. Such a sealing lip is also referred to in this context as a "pressure-activating lip".

Bisher jedoch wurden bei Tunnelprojekten zumeist Dichtungsprofile eingesetzt, die im Querschnitt gesehen spiegelsymmetrisch (bezogen auf die senkrechte Profil-Längsmittelebene) sind. Dabei hat sich herausgestellt, daß Profilbänder, die in Längsrichtung verlaufende Rillennuten und Kanäle besitzen (GB-B-2 170 561, GB-B-2 178 114, GB-B-2 182 987, EP-A-0 255 600, EP-A-0 306 796), hinsichtlich ihrer Dichtfunktion besonders wirksam sind. Je nach Profilstruktur und tunnelspezifischen Kriterien (d, w, So, S₁, Segmentversatz) wurden Dichtwerte von 4 bis 20 bar erzielt. Bei Nutmaßen d/w ≧ 0,18 und für hohe Dichtheiten von ≧ 20 bar mit erforderlichen vertikalen Verpressungen von mehr als 30 % können die bisher entwickelten Dichtungsprofile nicht mehr auf das Nutvolumen angepaßt konstruiert werden.So far, however, sealing profiles have mostly been used in tunnel projects, which are mirror-symmetrical in cross-section (based on the vertical longitudinal profile of the profile). It has been found that profile strips which have longitudinal groove grooves and channels (GB-B-2 170 561, GB-B-2 178 114, GB-B-2 182 987, EP-A-0 255 600, EP -A-0 306 796), are particularly effective with regard to their sealing function. Depending on the profile structure and tunnel-specific criteria (d, w, S o , S₁, segment offset), density values of 4 to 20 bar were achieved. With groove dimensions d / w ≧ 0.18 and for high tightness of ≧ 20 bar with required vertical pressing of more than 30%, the sealing profiles developed so far can no longer be designed to match the groove volume.

Der Erfindung liegt die überraschende Erkenntnis zugrunde, daß asymmetrische Dichtungsprofile gemäß Kennzeichen des Anspruchs 1 eine sehr hohe Dichtleistung aufweisen.The invention is based on the surprising finding that asymmetrical sealing profiles according to the characterizing part of claim 1 have a very high sealing performance.

Die Erfindung wird nun anhand von Ausführungsbeispielen unter Bezugnahme auf schematische Zeichnungen sowie in Verbindung mit Daten aus Dichtheitsprüfungen näher erläutert. Dabei zeigen die Fig. 1 bis 3 die erfindungsgemäßen Dichtungsprofile im Querschnitt gesehen.The invention will now be explained in more detail using exemplary embodiments with reference to schematic drawings and in connection with data from leak tests. 1 to 3 show the sealing profiles according to the invention seen in cross section.

Nach Fig. 1 soll der Spalt (1) mit dem Abstand So (unbelasteter Zustand) zweier angrenzender Segmente (2, 3) abgedichtet werden. Zu diesem Zweck werden in die Nuten (4, 5) jeweils ein strangförmiges Dichtungsprofil (6) aus Gummi oder gummiähnlichem Werkstoff eingesetzt. Jedes Dichtungsprofil weist zur Segment-Außenseite (7) hin eine druckaktivierende Lippe (8) sowie einen Profilfuß (9) auf, der wannenförmig ausgebildet ist. Die druckaktivierende Lippe (8) ist im unbelasteten Zustand vom Profilrücken (10) her in Richtung Spaltmitte (11) zur Druckwasserseite ausgerichtet. Die erfindungsgemäße Lippe (8) erhöht das Dichtungsprofil bei nur geringem Volumenbedarf. Im belasteten, d.h. verpreßten Zustand (Spaltabstand S₁) verschwindet der Zwischenraum (12) zwischen den beiden Dichtungsprofilen (6). Der Profilfuß (9) weist eine Abstützung (13) an der Nutschräge (14) auf, wodurch eine Verschiebung des Profiles (6) bei Kompression verhindert wird. Der wannenartige Profilfuß (9) hat die Aufgabe, den massiven Dichtungskörper in der Nut (4, 5) zu zentrieren, so daß auch bei einem Versatz der Dichtungsprofile eine Mindestkontaktbreite der Profile garantiert bleibt. Die drei Rillennuten (15, 16, 17) sind symmetrisch zueinander angeordnet, wobei die mittlere Nut (16) tiefer und breiter ist als die Nachbarnuten (15, 17).According to Fig. 1, the gap (1) should be sealed with the distance S o (unloaded state) between two adjacent segments (2, 3). For this purpose, a strand-shaped sealing profile (6) made of rubber or rubber-like material is inserted into the grooves (4, 5). Each sealing profile has a pressure-activating lip (8) towards the outside of the segment (7) and a profile foot (9) which is trough-shaped. The pressure-activating lip (8) is oriented in the unloaded state from the profile back (10) towards the middle of the gap (11) to the pressure water side. The lip (8) according to the invention increases the sealing profile with only a small volume requirement. In the loaded, ie compressed state (gap distance S₁), the gap (12) between the two sealing profiles (6) disappears. The profile foot (9) has a support (13) on the groove slope (14), which prevents a displacement of the profile (6) when compressed. The tub-like profile foot (9) has the task of centering the solid sealing body in the groove (4, 5), so that a minimum contact width of the profiles remains guaranteed even when the sealing profiles are offset. The three groove grooves (15, 16, 17) are arranged symmetrically to one another, the middle groove (16) being deeper and wider than the neighboring grooves (15, 17).

Anhand des Dichtungsprofiles (18) nach Fig. 2 werden nun hinsichtlich der erfindungsgemäßen Asymmetrieelemente (Lippe 8, Profilfuß 9) strukturelle Details beschrieben. Die Richtung der druckaktivierenden Lippe (8) im unbelasteten Zustand ist hier durch die Linie (19a) veranschaulicht, wobei diese Linienführung die Resultierende der beiden in einem unterschiedlichen Winkel zulaufenden Lippenflanken (20, 21) ist. Die in den Ansprüchen 1 und 2 angegebenen Winkelbereiche α ergeben sich aus den Linienführungen (19a, 19b), wobei die Linie (19b) den Verlauf der Spaltmitte angibt.With reference to the sealing profile (18) according to FIG. 2, structural details are now described with regard to the asymmetry elements (lip 8, profile foot 9) according to the invention. The direction of the pressure-activating lip (8) in the unloaded state is illustrated here by the line (19a), this line being the result of the two lip flanks (20, 21) tapering at a different angle. The angular ranges α specified in claims 1 and 2 result from the lines (19a, 19b), the line (19b) indicating the course of the gap center.

Die Linie (19b) ist zugleich Bezugspunkt für die Profilhöhe H. Der wannenförmige Profilfuß (9; Bereich B) kann bis zu 40 % der Nutbreite w (entspricht der Gesamtbreite der Profilbasisseite) einnehmen. Dieser obere Grenzwert sollte nicht überschritten werden, damit der Profilgrundkörper (Bereich A) auch noch bei Segmentversatz noch eine ausreichende Dichtwirkung ausübt. Die Abstützung (13), die dem Profilfuß (9) die wannenförmige Gestalt gibt, weist eine Gesamthöhe auf, die etwa der halben Nuttiefe d entspricht. Der massive Profilgrundkörper (Bereich A) weist ähnlich dem Dichtungsprofil (6) nach Fig. 1 drei Rillennuten (22, 23, 24) auf, wobei die mittlere Nut (23) hier eine andere Form hat als die beiden Nachbarnuten (22, 24). Direkt über der mittleren Nut (23) ist ein Kanal (25) angeordnet.The line (19b) is also the reference point for the profile height H. The trough-shaped profile foot (9; area B) can take up to 40% of the groove width w (corresponds to the total width of the profile base side). This upper limit should not be exceeded so that the profile body (area A) still exerts a sufficient sealing effect even when there is a segment offset. The support (13), which gives the profile foot (9) the trough-shaped shape, has an overall height which corresponds approximately to half the groove depth d. The solid profile base body (area A) has three groove grooves (22, 23, 24) similar to the sealing profile (6) according to FIG. 1, the middle groove (23) here having a different shape than the two neighboring grooves (22, 24) . A channel (25) is arranged directly above the central groove (23).

Nach Fig. 3 weist das Dichtungsprofil (26) zwei Rillennuten (27, 28), die eine unterschiedliche Form und Größe haben, und drei im wesentlichen gleichförmige Kanäle (29, 30, 31) auf. Rillennuten und Kanäle sind im Gegensatz zu den Profilen gemäß Fig. 1 und 2 asymmetrisch zueinander angeordnet. Dadurch erhält das Profil (26) neben den beiden erfindungsgemäßen Asymmetrieelementen, nämlich Lippe (8) und Profilfuß (9), weitere Asymmetrieelemente.According to Fig. 3, the sealing profile (26) has two groove grooves (27, 28) which have a different shape and size, and three substantially uniform channels (29, 30, 31). In contrast to the profiles according to FIGS. 1 and 2, groove grooves and channels are arranged asymmetrically to one another. This gives the profile (26) in addition to the two asymmetry elements according to the invention, namely lip (8) and profile foot (9), further asymmetry elements.
