Dichtanordnungen der oben beschriebenen Art sind für die verschiedensten Einsatzzwecke bekannt, wobei im folgenden insbesondere auf den Anwendungsbereich im Tunnelbau, wobei die Tunnelrohrsegmente wiederum insbesondere Einschwimmelemente sind, näher eingegangen wird (DE-C-31 01 332). Sealing arrangements of the type described above are known for a very wide variety of uses, the following being in more detail in particular on the area of application in tunnel construction, the tunnel tube segments again being in particular floating elements (DE-C-31 01 332).
Zur Abdichtung des Spaltes zwischen zwei Einschwimmelementen wird je eine Stirnseite mit einem Dichtrahmen (Stirndichtung) aus elastomerem Werkstoff versehen. Das zuletzt abgesenkte Teilstück wird gegen seinen bereits fest montierten To seal the gap between two floating elements, one end face is provided with a sealing frame (end seal) made of elastomeric material. The last lowered section is against its already firmly installed
Vorgänger gezogen, bis eine erste Abdichtung erreicht ist. Nachdem dann das Wasser aus der Kammer zwischen den beiden Stirnwänden der Schwlmmstucke gepumpt worden ist, wird das zuletzt abgesenkte Element durch den äußeren Wasserdruck so stark gegen seinen Nachbarn geschoben, daß die Stirndichtung ihre endgültige Zusammenpressung erfahrt und somit eine vollständige Abdichtung zustande kommt. Predecessor pulled until a first seal is achieved. After the water has been pumped out of the chamber between the two end walls of the sponges, the last lowered element is pushed so strongly against its neighbors by the external water pressure that the end seal is finally compressed and thus a complete seal is achieved.
Da im Rahmen des weltweiten Tunnelbaus immer größere Because as part of the global tunnel construction ever larger
Anforderungen an Elastomerdichtungen gestellt werden, insbesondere auch unter dem Gesichtspunkt zuverlässiger Abdichtung in Erdbebengebieten (z.B. Japan), besteht die Aufgabe darin, eine hochwirksame Dichtung bereit zu stellen, die selbst unter extremen Bedingungen einsatzfahig ist, und zwar über einen langen Zeitraum hinweg (100 Jahre). The requirements for elastomer seals, especially with regard to reliable sealing in earthquake areas (e.g. Japan), are to provide a highly effective seal that can be used even under extreme conditions over a long period of time (100 years ).

Nach Fig. 2 erfolgt die Abdichtung des Spaltes (6) zwischen den beiden Einschwimmelementen (1, 4) aus Beton mittels der Dichtung (7). Die Stirnseiten (2, 5) dieser Bauelemente sind jeweils mit einer Metallplatte (8, 9) belegt, die im Beton verankert ist. Die Metallplatte (8) tragt dabei seitliche MetalIprofile (10) und Metallstreifen (11), wobei die 2, the gap (6) is sealed between the two floating elements (1, 4) made of concrete by means of the seal (7). The end faces (2, 5) of these components are each covered with a metal plate (8, 9) which is anchored in the concrete. The metal plate (8) carries lateral metal profiles (10) and metal strips (11), the
Metallprofile und Metal Istreifen mittels einer Schraube (12) miteinander verbunden sind. Als Befestigungsmittel können auch L-forrmge StahIschienen (DE-C-31 01 332) zum Einsatz kommen. Metal profiles and actual metal tires are connected to each other by means of a screw (12). L-shaped steel rails (DE-C-31 01 332) can also be used as fasteners.
Die Dichtung (7) selbst besitzt einen Basisteil (13), der bezogen auf den Dichttei l (14) beidseitig unter Bildung von Flanschen (15, 16) verbreitert ist. Diese Flansche werden dabei von den Metallprofllen (10) und MetalIstreifen (11) verankernd umfaßt. An der Grundseite (17) des Basisteiles (13) sind fünf strangformig verlaufende Rillennuten (18, 19, 20) vorhanden, wobei die im Bereich der Langsmittelebene X angeordnete Rillennut (18) wenigstens 30 % breiter und/oder tiefer ist als die seitlich davon angeordneten Rillennuten (19, 20). The seal (7) itself has a base part (13) which is widened on both sides with respect to the sealing part l (14) to form flanges (15, 16). These flanges are anchored by the metal profiles (10) and metal strips (11). On the base side (17) of the base part (13) there are five groove grooves (18, 19, 20) running in the form of a strand, the groove groove (18) arranged in the area of the longitudinal center plane X being at least 30% wider and / or deeper than that on the side thereof arranged groove grooves (19, 20).

(21, 22). Diese Sei tenf lanken des trapezförmigen Dichttei les verlaufen winkelgleich, d.h. spiegelsymmetrisch bezogen auf die Längsmittelebene X. Die Stirnflache (23) des Dichtteiles ist e b e n f l ä c h i g ausgebi ldet. In der Mitte des trapezförmigen Dichtteiles (14), und zwar im Bereich der Längsmittelebene X, sind drei strangförmig verlaufende Kanäle (24, 25, 26) vorhanden, die direkt übereinander angeordnet und im wesentlichen von kreisförmiger Querschnittsgestalt sind. Dabei besitzt der sich im Bereich der Stirnfläche (23) befindende Kanal (26) einen geringeren Durchmesser als die beiden darunter angeordneten Kanäle (24, 25). (21, 22). These side flanks of the trapezoidal sealing part run at the same angle, i.e. mirror-symmetrical with respect to the longitudinal center plane X. The end face (23) of the sealing part is also formed. In the center of the trapezoidal sealing part (14), specifically in the area of the longitudinal center plane X, there are three channels (24, 25, 26) which run in the form of a strand and are arranged directly one above the other and are essentially circular in cross-sectional shape. The channel (26) located in the region of the end face (23) has a smaller diameter than the two channels (24, 25) arranged below it.

Fig. 3 zeigt nun eine Dichtung (27), wobei deren Basistei l (28) mit dem der Dichtung (7; Fig. 2) formidentisch ist. Auch die Umrisse des trapezförmigen Dichtteiles (29), nämlich die Seitenflanken (30, 31) und die Stirnflache (32), sind gleich. Dagegen sind die strangformig verlaufenden Kanäle völlig anders angeordnet. Im Gegensatz zu der Dichtung (7; Fig. 2) sind hier die Kanäle innerhalb der gesamten Querschnittsflache des trapezförmigen Dichttei les (29) vertei lt vorhanden, und zwar bezogen auf die Langsmlttelebene X unter im wesentlichen spiegelsymmetrischer Anordnung, wobei das Strukturpinzip im folgenden naher erläutert wird. Fig. 3 now shows a seal (27), the base part l (28) with that of the seal (7; Fig. 2) is identical in shape. The outlines of the trapezoidal sealing part (29), namely the side flanks (30, 31) and the end face (32), are also the same. In contrast, the channels running in the form of a strand are arranged completely differently. In contrast to the seal (7; Fig. 2) here the channels are distributed within the entire cross-sectional area of the trapezoidal sealing part (29), in relation to the longitudinal plane X below essentially mirror-symmetrical arrangement, the structural principle being explained in more detail below.
Die insgesamt acht Kanäle sind bezogen auf die Langsmittelebene X dreireihig (Reihen I, II, III) angeordnet, und zwar derart, daß sich die mittigen Kanäle (33, 34; Reihe II) innerhalb des Bereiches der Längsmillelebene X befinden, wahrend zwischen dieser Längsmillelebene und den beiden The total of eight channels are arranged in three rows (rows I, II, III) in relation to the longitudinal median plane X, in such a way that the central channels (33, 34; row II) are located within the area of the longitudinal plane X, between this longitudinal plane and the two
Seitenflanken (30, 31) jeweils die seitlichen Kanäle (35, 36, 37; Reihe I) bzw. (38, 39, 40; Reihe III) vorhanden sind, wobei die mittigen Kanäle (Reihe II) in einem Abstand e versetzt zu den seitlichen Kanälen (Reihen I, III) angeordnet sind. Hinsichtlich der Anzahl (m, n) der Kanäle gelten dabei folgende Parameter: Side flanks (30, 31) each have the lateral channels (35, 36, 37; row I) or (38, 39, 40; row III), the central channels (row II) being offset at a distance e from the lateral channels (rows I, III) are arranged. With regard to the number (m, n) of channels, the following parameters apply:
mittig angeordnete Kanäle (Reihe II): m = 2 channels arranged in the middle (row II): m = 2
seitlich angeordnete Kanäle (Reihe I bzw. III): n = m + 1 = 3 laterally arranged channels (row I or III): n = m + 1 = 3
Die Kanäle sind auch hier im wesentlichen von kreisförmiger Querschnittsgestalt, wobei die sich im Bereich der Stirnflache (32) des trapezförmigen Dichttei les (29) befindenden zwei Kanäle (37, 40) einen geringeren Durchmesser besitzen als die darunter angeordneten sechs Kanäle (33, 34, 35, 36, 38, 39). The channels here are also essentially of circular cross-sectional shape, the two channels (37, 40) located in the area of the end face (32) of the trapezoidal sealing part (29) having a smaller diameter than the six channels (33, 34) arranged underneath , 35, 36, 38, 39).
Fig. 4 zeigt nun zwei Strukturlerungsvarianten der Stirnflache (42) der Dichtung (41), wobei hinsichtlich der Anordnung der Kanäle auf die Fig. 3 verwiesen wird. Nach der einen Variante ist in der Mitte der Stirnflache des Dichtteiles, und zwar im Bereich der Längsmittelebene X, eine einzige Ri llennut (43) vorhanden. Eine zweckmäßige Alternative besteht dann, die Stirnfläche (42) mit mehreren FIG. 4 now shows two structural variants of the end face (42) of the seal (41), reference being made to FIG. 3 with regard to the arrangement of the channels. According to one variant, a single groove (43) is present in the middle of the end face of the sealing part, specifically in the area of the longitudinal center plane X. An expedient alternative is then the end face (42) with several
