Description

Die Erfindung betrifft eine Dichtung gemäß Oberbegriff des Anspruchs 1.The invention relates to a seal according to the preamble of claim 1.

Die Dichtungsrahmen eines Tunnel-Segmentes (Tübbing) aus Beton, Stahl, Stahlbeton oder Gußeisen bestehen aus vier zusammenge­setzten Profilbändern, wobei die vier Rahmenecken vorzugsweise nach dem Injection-Molding-Verfahren hergestellt werden. Die Profilbänder selbst weisen zumindest in Längsrichtung parallel verlaufende Rillennuten auf (DE-U-72 03 419, DE-U-72 29 665, DE-U-74 32 945, DE-C-25 13 365). Besonders wirksam hinsichtlich ihrer Dichtfunktion sind Profilbänder, die in Längsrichtung parallel verlaufende Rillennuten und Kanäle besitzen (DE-C-­28 33 345, DE-A-35 02 620, EP-A-0 210 326, EP-A-0 222 968, EP-A-0 255 600, EP-A-0 306 796).The sealing frames of a tunnel segment (tubbing) made of concrete, steel, reinforced concrete or cast iron consist of four composite profile strips, the four frame corners preferably being produced by the injection molding process. The profile strips themselves have at least longitudinal groove grooves (DE-U-72 03 419, DE-U-72 29 665, DE-U-74 32 945, DE-C-25 13 365). Profile strips which have groove grooves and channels running parallel in the longitudinal direction are particularly effective with regard to their sealing function (DE-C-28 33 345, DE-A-35 02 620, EP-A-0 210 326, EP-A-0 222 968, EP-A-0 255 600, EP-A-0 306 796).

Häufig genügt es, wenn jedes Tunnel-Segment einen Dichtungs­rahmen aufweist (Variante A). Unter besonderen Umständen kann es jedoch erforderlich werden, die Segmente mit einem Doppel­dichtungsrahmen (Variante B) zu versehenIt is often sufficient if each tunnel segment has a sealing frame (variant A). In special circumstances, however, it may be necessary to provide the segments with a double sealing frame (variant B)

Die Aufgabe der Erfindung besteht nun in der Weiterentwicklung der Variante B. Dabei soll neben der Erhöhung der Dichtwirkung insbesondere die schnellere Lokalisierung einer eventuell auftretenden Leckstelle und somit eine kostengünstigere Sanierung erreicht werden. Gelöst wird diese Aufgabe durch das Kennzeichen des Anspruchs 1. Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen genanntThe object of the invention is to further develop variant B. In addition to increasing the sealing effect, in particular the faster localization of any leakage that may occur and thus a more cost-effective refurbishment are to be achieved. This problem is solved by the characterizing part of claim 1. Appropriate embodiments of the invention are mentioned in the subclaims

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen unter Bezugnahme auf schematische Zeichnungen näher erläutert. Es zeigen:

  • Fig. 1 zwei Seiten eines Tunnel-Segmentes;
  • Fig. 2 einen schematischen Lageplan der Querfugen;
  • Fig. 3a, b, c das erfindungsgemäße Dichtungsquerprofil als Querverbindung zu dem Doppeldichtungsrahmen, u. z. unter verschiedenen Schnitten;
  • Fig. 4a, b eine weitere Ausführungsform des Dichtungs­querprofils;
  • Fig. 5 eine Tunnelröhre.
The invention is explained in more detail below on the basis of exemplary embodiments with reference to schematic drawings. Show it:
  • 1 shows two sides of a tunnel segment;
  • Fig. 2 is a schematic map of the transverse joints;
  • 3a, b, c the sealing cross profile according to the invention as a cross connection to the double sealing frame, uz under different cuts;
  • 4a, b a further embodiment of the sealing cross profile;
  • Fig. 5 shows a tunnel tube.

Fig. 1 zeigt ein Segment (1) (z.B. aus Beton) mit zwei umlaufenden Aussparungen (2, 3), die parallel verlaufen. In jede dieser Aussparungen wird nun ein Dichtungsrahmen eingesetzt. In die Querfugen (4, 5) selbst wird das erfindungs­gemäße Dichtungquerprofil angeordnet.Fig. 1 shows a segment (1) (e.g. made of concrete) with two circumferential recesses (2, 3) that run parallel. A sealing frame is now inserted into each of these recesses. The sealing cross profile according to the invention is arranged in the transverse joints (4, 5) itself.

Fig. 2 zeigt einen schematischen Lageplan der Querfugen. Bezüglich des Segmentes (1) mit der Seite (6) (Breite B) und der Seite (7) (Länge L) weisen die Querfugen (4, 5) folgende Dimensionierung auf, wobei die Segmentecke (8) Bezugspunkt ist:
Querfuge (4) : 1/2 B
Querfuge (5) : 1/4 L
Fig. 2 shows a schematic map of the transverse joints. With regard to the segment (1) with the side (6) (width B) and the side (7) (length L), the transverse joints (4, 5) have the following dimensions, the segment corner (8) being the reference point:
Transverse joint (4): 1/2 B
Cross joint (5): 1/4 L

Hinsichtlich der Tunnel-Segmente (9, 10, 11, 12, 13) längs der Ringfuge (14) sind die entsprechenden Querfugen analog angeordnet.With regard to the tunnel segments (9, 10, 11, 12, 13) along the ring joint (14), the corresponding transverse joints are arranged analogously.

Fig. 3a zeigt nun den Doppeldichtungsrahmen und das Dichtungsquerprofil längs der Schnittlinie A-A (Fig. 1). Dabei weisen hier die beiden Dichtungsrahmen (15a, b) drei gleichförmige Rillennuten (16) und zwei Kanäle (17) sowie eine zentrale Erhebung (18) im Profilrücken auf (EP-A-O 255 600). Zwischen diesen beiden Dichtungsrahmen ist das Dichtungsquerprofil (19), das aus einem Mittelteil (19a) und einem Außenteil (19b) besteht, als lückenlose Querverbindung angeordnet, die sich der Außenkontur der Dichtungsrahmen anpaßt. Dabei geht die Erhebung (18) und das Dichtungsquerprofil (19) höhengleich ineinander über. Auf diese Weise entsteht ein breiter Gesamtprofilrücken (20). Dichtungsrahmen (15a, b) und Dichtungsquerprofil (19) sind miteinander verklebt, verschweißt oder auf eine andere Weise miteinander verbunden.Fig. 3a now shows the double sealing frame and the sealing cross section along the section line A-A (Fig. 1). Here, the two sealing frames (15a, b) have three uniform groove grooves (16) and two channels (17) and a central elevation (18) in the profile back (EP-A-0 255 600). Between these two sealing frames, the sealing cross profile (19), which consists of a central part (19a) and an outer part (19b), is arranged as a gapless cross connection, which adapts to the outer contour of the sealing frame. The elevation (18) and the sealing cross profile (19) merge into one another at the same height. This creates a broad overall profile back (20). Sealing frame (15a, b) and sealing cross section (19) are glued, welded or connected to one another in some other way.

Fig. 3b (Schnitt B-B) und Fig. 3c (Schnitt C-C) zeigen das Dichtungsquerprofil (19) in Längsrichtung gesehen, wobei sowohl der Mittelteil (19a) wie auch der Außenteil (19b) mehrere Rillennuten (21) bzw. (22) aufweisen.Fig. 3b (section BB) and Fig. 3c (section CC) show the sealing cross profile (19) seen in the longitudinal direction, both the central part (19a) and the outer part (19b) having a plurality of groove grooves (21) and (22) .

Nach Fig. 4 verbindet das Dichtungsquerprofil (23) ebenfalls lückenlos die beiden Dichtungsrahmen (24a, b), die im Querschnitt gesehen drei Rillennuten und vier Kanäle aufweisen (DE-A-35 02 620). Dabei ist das Dichtungsquerprofil (23) höhengleich mit dem hier ebenflächigen Rücken (25a, b) der Dichtungsrahmen. Im Querschnitt gesehen kann das Dichtungsquerprofil eine Struktur gemäß Fig. 3b haben.4, the sealing cross profile (23) also connects the two sealing frames (24a, b), which have three groove grooves and four channels in cross section (DE-A-35 02 620). The sealing cross profile (23) is of the same height as the flat back (25a, b) of the sealing frame. Seen in cross section, the sealing cross profile can have a structure according to FIG. 3b.

Fig. 5 zeigt nun eine Tunnelröhre (26), wobei die kleinste Einheit das Tunnel-Segment (27) mit einer Breite (28) (in Tunnellängsrichtung) und einer Länge (29) (in Tunnelquerrichtung) ist Die nächst größere Einheit ist der Tunnelring, wobei hier drei Tunnelringe (30, 31, 32) dargestellt sind. Hinsichtlich Reparaturmaßnahmen ist es ausreichend, wenn nicht jedes Segment, sondern z. B. lediglich die Semente jedes fünften Tunnelringes innerhalb der Segmentbreite das erfindungsgemäße Dichtungsquerprofil aufweisen. Auf diese Weise wird bei Eindringen von Feuchtigkeit an irgendeiner Stelle der Tunnelröhre eine wirksame Abschottung erzielt und somit ein schnelleres Auffinden der Leckstelle erreicht.5 now shows a tunnel tube (26), the smallest unit being the tunnel segment (27) with a width (28) (in the longitudinal direction of the tunnel) and a length (29) (in the transverse direction of the tunnel). The next larger unit is the tunnel ring , being here three tunnel rings (30, 31, 32) are shown. With regard to repair measures, it is sufficient if not every segment, but e.g. B. only the elements of every fifth tunnel ring within the segment width have the sealing cross profile according to the invention. In this way, if moisture penetrates at any point in the tunnel tube, an effective isolation is achieved and the leakage location is thus found more quickly.
