Description

Die Erfindung bezieht sich auf ein Dichtungsprofil gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a sealing profile according to the preamble of claim 1.

Derartige Dichtungsprofile sind bekannt (DE-C-28 33 345, DE-U-85 02 036, DE-U-85 21 068, DE-U-85 32 264) und haben sich für den Tunnelbau bei der Anwendung von Segmenten (Tübbings) aus Beton, Gußeisen, Stahl oder Stahlbeton bewährt.Such sealing profiles are known (DE-C-28 33 345, DE-U-85 02 036, DE-U-85 21 068, DE-U-85 32 264) and have been used for tunneling when using segments (segments) ) made of concrete, cast iron, steel or reinforced concrete.

Die wesentlichen Anforderungen an ein solches Profil sind:

  • 1. Möglichst geringe zu überwindende Kräfte beim Zusammenschrauben der Segmente.
  • 2. Sicherer Halt innerhalb der Nut der Segmente.
  • 3. Möglichst hohe Kontaktspannung und damit gleichbedeutend hohe Abdichtleistung auch bei unvollständiger Verpressung der Profile.
  • 4. Möglichst geringe Spannungsrelaxation über die geplante Nutzungdauer des Tunnelbauwerkes.
The main requirements for such a profile are:
  • 1. Minimum forces to be overcome when screwing the segments together.
  • 2. Secure hold within the groove of the segments.
  • 3. As high a contact voltage as possible and thus an equivalent high sealing performance even with incomplete pressing of the profiles.
  • 4. Stress relaxation as low as possible over the planned service life of the tunnel structure.

In den letzten Jahren stand hauptsächlich die Erfüllung der Anforderungen 1 und 2 im Mittelpunkt der Entwicklungstätigkeit und auch der praktischen Anwendung, was zur Anordnung von Rillennuten und Kanälen im Profilquerschnitt in besonderer geometrischer Anordnung geführt hat, mit dem Ergebnis einer sehr gleichmäßigen Verteilung der Steifigkeit über die Breite des Profiles. Solche Profile genügen erhöhten Anforderungen an die langfristig zu garantierende Dichtungswirkung aufgrund zu geringer Kontaktspannung und zu hoher Spannungsrelaxations­neigung nicht, da die zur Verfügung stehende Reaktionskraft bei Zusammenpressen des Profiles durch die gesamte Kontaktbreite geteilt wird und so eine niedrige Kontaktspannung erreicht wird und zudem die Spannungsrelaxation durch die zahlreich angeordneten Kanäle beschleunigt wird.In recent years, the fulfillment of requirements 1 and 2 has mainly been the focus of development work and practical application, which has led to the arrangement of groove grooves and channels in the profile cross section in a special geometric arrangement, with the result of a very uniform distribution of the rigidity over the Width of the profile. Such profiles do not meet the increased demands on the sealing effect to be guaranteed in the long term due to the contact stress being too low and the tendency to stress relaxation being too high, since the available reaction force when the profile is pressed together is divided by the entire contact width, thus achieving a low contact stress and also the stress relaxation by numerous arranged channels is accelerated.

Aufgabe der Erfindung ist es daher, ein Dichtungsprofil für Segmente von Tunnelröhren zu entwicklen, das unter Beachtung der Anforderungen 1 und 2, insbesondere die Anforderungen 3 und 4 in befriedigender Weise löst, um auch Tunnel mit einer Tiefenlage von mehr als 100 m langfristig sicher abzudichten. Diese Aufgabe wird gelöst durch ein Dichtungsprofil mit den kennzeichnenden Merkmalen des Anspruchs 1.The object of the invention is therefore to develop a sealing profile for segments of tunnel tubes, which satisfies requirements 1 and 2, in particular requirements 3 and 4 in a satisfactory manner in order to reliably seal tunnels with a depth of more than 100 m in the long term . This object is achieved by a sealing profile with the characterizing features of claim 1.

Der durchgehende Steg führt zu einer Konzentration der bei Verpressen des Profiles mobilisierten Reaktionskraft auf diesen Steg mit dem Ergebnis einer Spannungskonzentration und damit erhöhten Dichtwirkung. Die Spannungsrelaxation tritt darüber hinaus bei diesem Steg ohne Lochschwächung wesentlich vermindert ein.The continuous web leads to a concentration of the reaction force mobilized when the profile is pressed onto this web, with the result of a stress concentration and thus an increased sealing effect. The stress relaxation also occurs significantly less with this bridge without hole weakening.

Zweckmäßige Ausgestaltungen sind in den Unteransprüchen genannt.Appropriate configurations are mentioned in the subclaims.

Die Erfindung wird nun anhand von Ausführungsbeispielen unter Bezugnahme von schematischen Zeichnungen näher erläutert. Dabei zeigen die

  • Fig. 1, 2 Dichtungsprofile mit dem erfindungsgemäßen Steg bei ebenflächigem Profilrücken und die
  • Fig. 3a, 3b, 4, 5 Dichtungsprofile mit dem erfindungsgemäßen Steg, wobei der Profilrücken eine oder mehrere Erhebungen aufweist.
The invention will now be explained in more detail using exemplary embodiments with reference to schematic drawings. The show
  • Fig. 1, 2 sealing profiles with the web according to the invention with a flat profile back and the
  • Fig. 3a, 3b, 4, 5 sealing profiles with the web according to the invention, wherein the profile back has one or more elevations.

Sämtliche Profile sind im Querschnitt dargestellt und verdeutlichen den noch nicht verpreßten Zustand.All profiles are shown in cross section and illustrate the not yet compressed state.

Nach Fig. 1 besitzen die beiden Segmente (1) und (2) je eine Nut (3) und(4). In diesen Nuten sind zwei Dichtungsprofile eingeklebt. Im Montagezustand berühren sich die Profile Rücken an Rücken, wobei der Profilrücken ebenflächig ausgebildet ist. Jedes dieser Profile weist an der Basisseite vier Rillennuten (5) bis (8) auf. Weiterhin besitzt das Profil zwei Kanäle (9) und (10) sowie einen mittleren durchgehenden und tragenden Steg (11). Bei der Anordnung von vier Rillennuten entstehen zwei weitere Stege (12) und (13), die durch die hier angeordneten Kanäle (9) und (10) in ihrer Tragwirkung reduziert sind, um eine Spannungsspitz im zentralen Steg (11) zu erzeugen. Werden nun die Profile durch eine Verschraubung der Segmente (1) und (2) gegeneinandergepreßt, so wird die dabei erzeugte Reaktionskraft in den massiven durchgehenden Stegen (11) konzentriert, mit dem Ergebnis einer hohen Kontaktspannung und Dichtungswirkung zwischen den Profilen.1, the two segments (1) and (2) each have a groove (3) and (4). Two sealing profiles are glued into these grooves. In the assembled state, the profiles touch each other back to back, the profile back being flat. Each of these profiles has four groove grooves (5) to (8) on the base side. Furthermore, the profile has two channels (9) and (10) and a central continuous and load-bearing web (11). The arrangement of four groove grooves creates two further webs (12) and (13), which are reduced in their load-bearing capacity by the channels (9) and (10) arranged here in order to generate a stress peak in the central web (11). If the profiles are pressed against each other by screwing the segments (1) and (2) together, the reaction force generated is concentrated in the solid, continuous webs (11), with the result of a high contact tension and sealing effect between the profiles.

Die Fig. 2 zeigt ebenfalls ein Profil mit ebenflächigem Profilrücken. Zwischen der mittleren Nut (14) und den beiden Außennuten (15) und (16) befindet sich jeweils ein durchgehender Steg (17) bzw. (18). Über den beiden Außennuten (15) und (16), die sich in den Eckbereich des Profiles erstrecken, sind jeweils ein gleichförmiger Kanal (19) bzw. (20) angeordnet, wobei der Mittelpunkt der Kanäle in der Höhenlage der Oberkante der mittleren Rillennut (14) liegt.2 also shows a profile with a flat profile back. Between the middle groove (14) and the two outer grooves (15) and (16) there is a continuous web (17) and (18). Above the two outer grooves (15) and (16), which extend into the corner area of the profile, a uniform channel (19) and (20) are arranged, with the center of the channels at the height of the upper edge of the central groove ( 14) lies.

Nach Fig. 3a befinden sich in den Nuten (3) und (4) der beiden Segmente (1) und (2) zwei eingeklebte Dichtungsprofile. Der Rücken der Profile weist eine Erhebung (21) auf, wodurch ein unebener Profilrücken entsteht. Die Höhe der Erhebung beträgt etwa 2,5 mm. Durch die Anordnung der Erhebung wird die Kontaktbreite zweier gegenüberstehender Profile weiter reduziert, insbesondere dann, wenn es bei unvermeidlichen Montageungenauigkeiten zu einem Versatz der beiden Profilachsen gegeneinander kommt. Das Profil nach Fig. 3a weist ferner drei gleichförmige Rillennuten (22), (23) und (24) auf, die untereinander den gleichen Abstand besitzen. Zwischen der mittleren Nut (23) und den beiden Außennuten (22) und (24) befindet sich jeweils ein durchgehender Steg (25) bzw. (26). Die Erhebung (21) im Profilrücken ist in Kraftwirkungsrichtung der beiden durchgehenden Stege (25) und (26) angeordnet. Der Anstieg (27) der Erhebung (21) ist hier etwa gleich dem Anstieg der seitlichen Flanke (28). Zwischen den Außennüten (22) und (24) und den seitlichen Profilrändern befindet sich jeweils ein gleichförmiger Kanal (29) bzw. (30), wobei der Mittelpunkt der Kanäle in der Höhenlage der Oberkante der drei Rillennuten liegt. Werden nun die Profile durch eine Verschraubung der Segmente (1) und (2) gegeneinander gepreßt, so wird die dabei erzeugte Reaktionskraft in den massiven, durchgehenden Stegen (25) und (26) konzentriert mit dem Ergebnis einer hohen Kontaktspannung und Dichtwirkung zwischen den Profilen.According to Fig. 3a there are two glued sealing profiles in the grooves (3) and (4) of the two segments (1) and (2). The back of the profiles has an elevation (21), which creates an uneven profile back. The height of the elevation is approximately 2.5 mm. The arrangement of the elevation further reduces the contact width of two opposing profiles, in particular when the two profile axes are offset from one another in the event of inevitable assembly inaccuracies. 3a also has three uniform groove grooves (22), (23) and (24), which are at the same distance from one another. There is a continuous web (25) and (26) between the middle groove (23) and the two outer grooves (22) and (24). The elevation (21) in the back of the profile is arranged in the direction of action of the two continuous webs (25) and (26). The rise (27) of the elevation (21) is approximately equal to the rise of the side flank (28). Between the outer grooves (22) and (24) and the lateral profile edges there is in each case a uniform channel (29) or (30), the center point of the channels being at the height of the upper edge of the three groove grooves. If the profiles are pressed against each other by screwing the segments (1) and (2) together, the reaction force generated is concentrated in the solid, continuous webs (25) and (26) with the result of a high contact tension and sealing effect between the profiles .

Bei einem Versatz (31) der Profile (Fig. 3b) ist die Kontaktbreite reduziert und die Spannung wiederum erhöht.If the profiles are offset (31) (FIG. 3b), the contact width is reduced and the voltage is increased again.

Die Fig. 4 stellt bezüglich der Anzahl und Anordnung der Rillennuten und Kanäle des gleiche Profil wie bei Fig. 3a, b dar. Neben der zentralen Erhebung (21a) weist hier das Profil noch zwei weitere Erhebungen (21b) und (21c) an den Rändern des Profilrückens auf. Die Erhebung (21b) und (21c) haben hier den gleichen Anstiegswinkel wie die Flanken (28). Durch diese Randerhebungen wird auch bei extremen Versätzen der Profile eine wirksame Abdichtung erzielt.4 shows the same profile as in FIGS. 3a, b with regard to the number and arrangement of the groove grooves and channels. In addition to the central elevation (21a), the profile here also has two further elevations (21b) and (21c) Edges of the back of the profile. The elevation (21b) and (21c) here have the same rise angle as the flanks (28). With these edge elevations, an effective seal is achieved even with extreme offsets of the profiles.

Die Fig. 5 zeigt ebenfalls ein Profil mit unebenen Profilrücken, der durch die Erhebung (32) gebildet wird. Der Anstieg (33) dieser Erhebung besitzt dabei nicht die gleichen Anstiegeswinkel wie die seitliche Flanke (34). Im Gegensatz zu dem Profil nach Fig. 3a, b wird die Erhebung (32) übergangslos gebildet, d. h. ohne Vorhandensein einer Zwischenstufe. Zwischen der mittleren Rillennut (35) und den beiden Außennuten (36) und (37), wobei die mittlere Nut breiter und tiefer ist als die beiden anderen Nuten, befindet sich jeweils ein durchgehender Steg (38) bzw. (39). Über den Außennuten weist dieses Profil seitlich versetzt jeweils einen gleichförmigen Kanal (40) bzw. (41) auf.Fig. 5 also shows a profile with uneven profile back, which is formed by the elevation (32). The rise (33) of this elevation does not have the same rise angle as the side flank (34). In contrast to the profile according to Fig. 3a, b, the elevation (32) is formed without transition, d. H. without the presence of an intermediate stage. Between the central groove (35) and the two outer grooves (36) and (37), the central groove being wider and deeper than the other two grooves, there is a continuous web (38) and (39). Above the outer grooves, this profile has a uniform channel (40) or (41) laterally offset.

Sämtliche Profile bestehen aus einer Kautschukmischung auf Basis von Polychloropren, EPDM, Nitril-Kautschuk oder anderen quell-, witterungs- und chemikalienbeständigen Kautschuktypen. Die Härte in Shore A beträgt üblicherweise zwischen 35 und 80°.All profiles consist of a rubber mixture based on polychloroprene, EPDM, nitrile rubber or other types of rubber that are resistant to swelling, weathering and chemicals. Shore A hardness is usually between 35 and 80 °.

Jedes Segment (1) bzw. (2) erhält einen passenden Rahmen aus vier zusammengefügten Dichtungsprofilen, wobei die vier Rahmenecken der Dichtung im Injections-Moulding-Verfahren hergestellt werden. Während dieses Verfahrens sind die Kanäle üblicherweise mit konischen Stöpseln verschlossen.Each segment (1) or (2) receives a suitable frame made of four joined sealing profiles, whereby the four frame corners of the seal are manufactured using the injection molding process. During this process, the channels are usually closed with conical plugs.
