Abstract

The method involves separating pipes and/or pipelines (16) e.g. district heating pipeline, from anchoring sections (10) and projecting suspensions in the tunnel sections. Pipe pieces (36) of small diameter are slided with respect to the tunnel sections in a rail laid in the tunnel sections. The pipes and/or the pipelines are slided in a support (20) arranged in the pipe pieces until an entire pipe section is lined with opposite pipe pieces. Gaps formed between the pipe pieces and the tunnel sections are filled with filling material (34). An independent claim is also included for a system for cleaning tunnel sections comprising a pipe piece with small diameter than tunnel sections.

Description

Die Erfindung betrifft ein Verfahren zur Sanierung einer Tunnelröhre sowie ein System zur Durchführung dieses Verfahrens.The invention relates to a method for the rehabilitation of a tunnel tube and a system for carrying out this method.

Auch Tunnelröhren unterliegen einem Alterungsprozess und die Praxis hat gezeigt, daß je nach Umgebungsbedingungen auch bei aus Beton hergestellten Tunnelröhren Schäden auftreten können, die eine vollständige Sanierung der Tunnelröhre bedingen. Ist die Tunnelröhre beispielsweise aus vorgepreßten Rohrstücken hergestellt worden, die jeweils eine Stoßfläche bilden, besteht die Gefahr, daß insbesondere in diesen Stoßflächen Wassereinsickerungen zu fortschreitenden Schäden im Betontragwerk führen.Even tunnel tubes are subject to aging and practice has shown that, depending on the environmental conditions, damage can also occur in tunnels made of concrete, which require a complete renovation of the tunnel tube. If the tunnel tube has been made, for example, from pre-pressed pieces of pipe, which each form an abutment surface, there is a risk that, especially in these abutment surfaces, water infiltration leads to progressive damage in the concrete structure.

Eine Möglichkeit für eine Sanierung liegt darin, die zu sanierende Tunnelröhre mit ihrer Innenlaibung durch eine vollflächige Rundumabdichtung zu versehen und nachträglich die alte Tunnelröhre mit Ortbeton oder Fertigteilen (Tübbingen) auszukleiden. Bei beiden Varianten wird ein erheblicher Anteil des freien Tunnelquerschnitts während der Sanierungsmaßnahme durch Spezialgerätedes Tunnelbaus, beispielsweise eines Schalwagens zum Einbringen des Ortbetons bzw. einem Erektor zum Versetzen von Tübbingen, in Anspruch genommen. Außerdem ist der Längstransport des Frischbetons zur Betonierstelle bzw. der Transport der schweren und unhandlichen Beton-Fertigteile (Tübbinge) insbesondere bei langen Tunnelbauwerken mit einem sehr hohen Aufwand verbunden.One possibility for a refurbishment is to provide the tunnel tube to be rehabilitated with its inner reveal by a full-surface Rundumabdichtung and subsequently to line the old tunnel tube with in-situ concrete or prefabricated parts (Tübbingen). In both variants, a significant portion of the free tunnel cross-section during the rehabilitation measure by Spezialgeräted the tunnel construction, such as a scarf car for introducing the in-situ concrete or a Erector to move Tuebbingen, used. In addition, the longitudinal transport of fresh concrete for concreting or the transport of heavy and cumbersome prefabricated concrete parts (tubbing) is associated with a very high cost, especially for long tunnel structures.

Besonders kompliziert sind diese konventionellen Sanierungsverfahren, wenn in der Tunnelröhre Rohre und/oder Leitungen verlaufen, beispielsweise Fernwärmeleitungen, Wasserleitungen, Gasleitungen, Ölleitungen, Elektroleitungen, etc. und diese vor der Sanierung der Tunnelröhre zu entfernen bzw. nach der Sanierung wieder neu einzubringen sind, da sie durch jeweilige Schächte, die zu der unterirdischen Tunnelleitung führen, herausgehoben bzw. wieder eingebracht werden müssen.These conventional rehabilitation processes are particularly complicated if pipes and / or lines run in the tunnel tube, for example district heating pipes, water pipes, gas pipes, oil pipes, electric lines, etc. and these are to be removed before the tunnel pipe is rehabilitated or to be re-introduced after the renovation, because they have to be lifted out or brought back through respective shafts leading to the underground tunnel.

Aufgabe der Erfindung ist es daher, ein Verfahren zur Sanierung einer Tunnelröhre an die Hand zu geben, welches wirtschaftlich und schnell die Sanierung insbesondere einer unterirdischen Tunnelröhre ermöglicht, so daß die betriebliche Unterbrechung der Anlage auf ein Minimum reduziert wird.The object of the invention is therefore to provide a method for the rehabilitation of a tunnel tube at hand, which economically and quickly allows the rehabilitation of a particular underground tunnel tube, so that the operational interruption of the system is reduced to a minimum.

Erfindungsgemäß wird die Aufgabe durch ein Verfahren mit den Verfahrensschritten des Anspruchs 1 gelöst.According to the invention the object is achieved by a method with the method steps of claim 1.

Demnach weist ein Verfahren zur Sanierung einer Tunnelröhre mit im Tunnel über seine Länge verlaufenden Rohren und/oder Leitungen folgende Schritte auf:Accordingly, a method of rehabilitating a tunnel tube having tubes and / or conduits extending through its length in the tunnel comprises the following steps:

Trennen der Rohre und/oder Leitungen von ihrer Verankerung in der Tunnelröhre und vorübergehendes Aufhängen der Rohre und/oder Leitungen in der Tunnelröhre;Separating the tubes and / or conduits from their anchoring in the tunnel tube and temporarily suspending the tubes and / or conduits in the tunnel tube;

Einschieben von Rohrstücken mit bezogen auf die Tunnelröhre kleinerem Durchmesser auf mindestens einer in der Tunnelröhre verlegten Schiene, während gleichzeitig die Rohre und/oder Leitungen auf einem jeweils in dem Rohrstück angeordneten Auflager gleiten bis die gesamte Tunnelröhre mit aneinanderliegenden Rohrstücken ausgekleidet ist, undInserting pieces of pipe with respect to the smaller diameter tunnel tube on at least one laid in the tunnel tube while the tubes and / or pipes slide on a respectively arranged in the pipe piece supports until the entire tunnel tube is lined with adjacent pipe sections, and

Verfüllen des sich zwischen den Rohrstücken und der Tunnelröhre bildenden Ringspalts mit einem geeigneten Füllmaterial.Fill the annular gap forming between the pipe sections and the tunnel tube with a suitable filling material.

Das neue Verfahren ermöglicht es somit, während der Sanierung der beschädigten Tunnelröhre die in ihr verlaufenden Rohre und/oder Leitungen der Tunnelröhre zu belassen. Sie müssen lediglich im Bereich des Eingangs des Tunnels abgetrennt werden, damit die am Eingang des Tunnels bereitgestellten Rohrstücke, die zur Innenauskleidung der Tunnelröhre dienen, über die Rohre und/oder Leitungen geschoben werden können. Dabei sind in den entsprechenden Rohrstücken auch Lager vorgesehen, auf denen die Rohre und/oder Leitungen entlang gleiten können. Nach vollständigem Einschieben sämtlicher Rohrstücke, die somit eine dichte Innenauskleidung bilden, wird der Bereich zwischen den Rohrstücken und der Tunnelröhre mit einem geeigneten Füllmaterial, beispielsweise einem Fließbeton, verfüllt.The new method thus makes it possible, during the renovation of the damaged tunnel tube, to leave the tubes and / or lines of the tunnel tube running in it. They only have to be cut off at the entrance of the tunnel so that the pipe sections provided at the entrance of the tunnel, which serve as the inner lining of the tunnel tube, can be pushed over the pipes and / or pipes. In this case, bearings are provided in the corresponding pipe sections on which the pipes and / or lines can slide along. After complete insertion of all pipe sections, which thus form a dense inner lining, the area between the pipe sections and the tunnel tube with a suitable filling material, such as a fluid concrete, filled.

Besondere Vorteile der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Particular advantages of the invention will become apparent from the subsequent claims to the main claim.

So kann die Tunnelröhre vorzugsweise vor Einschieben der Rohrstücke mit einer Abdichtung rundum abgedichtet werden. Bei einer derartigen Abdichtung kann es sich beispielsweise um eine flexible Kunststoffolie handeln, die nach der Sanierung der Tunnelröhre ein Eindringen von Wasser in die nachträglich eingebrachte Innenschale verhindert.Thus, the tunnel tube can preferably be completely sealed with a seal before inserting the pipe sections. Such a seal can be, for example, a flexible plastic film which prevents the penetration of water into the subsequently introduced inner shell after the renovation of the tunnel tube.

Besonders bevorzugt werden im Bereich der mindestens einen Schiene an den Stellen der Tunnelröhre, an denen die mindestens eine Schiene verankert wird, Kernbohrungen eingebracht werden, in die anschließend rundum geschlossene Formteile eingesetzt werden, die einen Teil der Abdichtung der Tunnelröhre bilden, bevor die mindestens eine Schiene mittels entsprechender in die Formteile eingreifenden Befestigungsmittel befestigt wird. Mit dieser bevorzugten Lösung wird sichergestellt, daß die in der Tunnelröhre verlaufende Abdichtung an keiner Stelle durchbrochen werden muß. Die zur Befestigung der mindestens einen Schiene in die zu sanierende Tunnelröhre eingesetzten Befestigungsmittel durchstoßen aufgrund dieser Lösung die Abdichtung nicht. Vielmehr wird die Abdichtung in den Bereichen, in denen die Befestigungsmittel in die Tunnelröhre hineinreichen, soweit ausgewölbt, daß diese die Befestigungsmittel, also beispielsweise die als Gewindestange ausgebildeten Befestigungsanker, umschließen. Dabei werden diese Ausstülpungen durch eigens hierfür vorgesehene und mit dem Rest der Abdichtung dicht verschweißten Formteilen gebildet.Particularly preferred are in the region of at least one rail at the points of the tunnel tube to which the at least one rail is anchored, core holes are introduced, are then used in the all-round closed moldings that form part of the seal of the tunnel tube before the at least one Rail is secured by means of appropriate engaging in the moldings fastener. With this preferred solution it is ensured that the seal running in the tunnel tube at no point must be broken. The fastening means used for fastening the at least one rail in the tunnel tube to be rehabilitated pierce due to this solution, the seal not. Rather, the seal in the areas where the fasteners extend into the tunnel tube, bulged so far that they enclose the fastening means, so for example, designed as a threaded rod fastening anchor. These protuberances are formed by specially provided for this purpose and tightly welded to the rest of the seal moldings.

Vorzugsweise gleiten die Rohrstücke während des Einschiebens auf der mindestens einen Schiene über an ihrer Außenfläche vorgesehenen wahlweise schmierbare Gleitflächen. Hierdurch kann in vorteilhafter Weise der Pressdruck zum Einschieben der Rohrstücke reduziert werden.Preferably, the pipe pieces slide during insertion on the at least one rail provided on its outer surface optionally lubricious sliding surfaces. As a result, the pressing pressure for inserting the pipe sections can be reduced in an advantageous manner.

Die in der Tunnelröhre verlaufenden Rohre und/oder Leitungen werden vor dem Einschieben der Rohrstücke an wenigstens einem der Enden der Tunnelröhre abgetrennt und nach Einschieben der Rohre wieder verbunden.The pipes and / or conduits running in the tunnel tube are separated off at at least one of the ends of the tunnel tube before insertion of the tube pieces and reconnected after insertion of the tubes.

Die Erfindung betrifft weiterhin ein System zur Durchführung eines Verfahrens zur Sanierung einer Tunnelröhre nach einem der vorangehenden Ansprüche mit den Elementen gemäß Anspruch 7. Zu den Systemelementen gehören:

  • Rohrstücke mit einem kleineren Durchmesser als die Tunnelröhre,
  • mindestens eine in der Tunnelröhre über Befestigungsmittel verlegbare Schiene,
  • eine Hydraulikpresse zum Vortrieb der Rohrstücke und wahlweise
  • eine die Tunnelröhre rundum abdichtende Dichtung, die rundum dichte Formteile aufweist, in die die Befestigungsmittel der mindestens einen Schiene verankerbar sind.
The invention further relates to a system for carrying out a method of rehabilitating a tunnel tube according to one of the preceding claims comprising the elements according to claim 7. The system elements include:
  • Pipe pieces with a smaller diameter than the tunnel tube,
  • at least one rail which can be laid in the tunnel tube via fastening means,
  • a hydraulic press for propulsion of the pipe sections and optionally
  • a sealing the tube around the sealing gasket, which has all-round dense moldings, in which the fastening means of the at least one rail can be anchored.

Besonders bevorzugt weisen die Rohrstücke an der Stelle, an dem diese auf der mindestens einen Schiene aufliegen eine Gleitfläche auf, an die nach innen zum Rohrstück wahlweise eine Schmiermittelbohrung anschließt.Particularly preferably, the pipe sections at the point where they rest on the at least one rail on a sliding surface, to which inwardly connects to the pipe piece either a lubricant bore.

Weiterhin ist innerhalb ausgewählter Rohrstücks mindestens ein Auflager zur gleitenden Aufnahme der Rohre und/oder Leitungen angeordnet. So mag es ausreichen in jedem dritten oder jedem fünften Rohrstück ein Auflager vorzusehen.Furthermore, at least one support for slidably receiving the tubes and / or lines is disposed within selected pipe section. So it may be sufficient to provide a support in every third or every fifth pipe section.

Schließlich ist es besonders vorteilhaft, wenn die Formteile, in denen die Befestigungsmittel zur Befestigung der Schiene in der Tunnelröhre gehalten werden, mindestens einen Einfachdorn, vorteilhaft aber einen Doppeldorn aufweisen, der einerseits in eine Kernbohrung in der Tunnelröhre einsetzbar ist und der andererseits die Befestigungsmittel aufnimmt. Das vorgesehene Formteil wird mit einem ersten Vergußmaterial, beispielsweise einem Vergußmörtel in die Kernbohrung eingesetzt. Das Innere des jeweiligen Formteils kann mit einem anderen Vergußmaterial, beispielsweise Epoxydharz ausgegossen werden, bevor das Befestigungsmittel, beispielsweise eine Gewindestange, eingeführt wird, so daß nach Erstarren der Vergußmasse das Befestigungsmittel fest in der zu sanierenden Tunnelröhre verankert ist.Finally, it is particularly advantageous if the molded parts, in which the fastening means for fastening the rail are held in the tunnel tube, have at least one single mandrel, but advantageously a double mandrel, which can be inserted on the one hand into a core bore in the tunnel tube and on the other hand receives the fastening means , The intended molding is used with a first potting material, such as a grout in the core hole. The interior of the respective molded part can be poured with another potting material, such as epoxy, before the fastener, such as a threaded rod, is introduced so that after solidification of the potting compound, the fastener is firmly anchored in the tunnel tube to be rehabilitated.

Figur 1 zeigt im Längsschnitt eine Tunnelröhre 10. Sie ist aus verpreßten Rohrstücken 12 gebildet worden. In Figur 1 ist am Eingang der Tunnelröhre 10 ein Schacht 14 gezeigt. Innerhalb der Tunnelröhre 10 verlaufen parallel zwei Rohrleitungen 16, die im hier dargestellten Ausführungsbeispiel beispielsweise Fernwärmeleitungen darstellen können. FIG. 1 shows a longitudinal section of a tunnel tube 10. It has been formed from compressed pipe sections 12. In FIG. 1 At the entrance of the tunnel tube 10, a shaft 14 is shown. Within the tunnel tube 10 parallel two pipes 16, which may represent, for example, district heating pipelines in the illustrated embodiment.

In den Figuren 2, 3 und 4 sind jeweils unterschiedliche Bauabschnitte innerhalb der zu sanierenden Tunnelröhre 10 gezeigt. So zeigt die Figur 2, das heißt der Querschnitt entlang der Schnittlinie I-I in Figur 1, den Urzustand im Bestandstunnel.In the FIGS. 2, 3 and 4 each different sections within the tunnel tube to be rehabilitated 10 are shown. That's how it shows FIG. 2 , ie the cross section along the section line II in FIG FIG. 1 , the original state in the existing tunnel.

So zeigt der Querschnitt in Figur 2, daß die Tunnelröhre 10 im hier dargestellten Ausführungsbeispiel kreisrund ausgeführt ist. Im Rahmen der Erfindung kann aber auch jede beliebige andere Querschnittsform verwendet werden. Innerhalb der Tunnelröhre 10 sind auf entsprechenden Podesten 18 und auf diesen aufgebrachten Lagern 20 die Medienrohre 16 aufgelagert. Die hier jeweils seitlich angeordneten Medienrohre 16 weisen jeweils Verstrebungen 22 auf. Zwischen den Seitenwandungen der Verstrebung 22 ist ein Längssteg 24 und darüber ein Laufsteg 26 angeordnet. Entlang des Längsstegs 24 können zusätzlich Leitungen verlaufen, die hier nicht dargestellt sind, beispielsweise Entwässerungsleitungen, Stromleitungen, etc.This is how the cross section in FIG. 2 in that the tunnel tube 10 is of circular design in the exemplary embodiment shown here. In the context of the invention, however, any other cross-sectional shape can also be used. Within the tunnel tube 10, the media tubes 16 are mounted on corresponding platforms 18 and on these applied bearings 20. The here each arranged laterally media tubes 16 each have braces 22. Between the side walls of the strut 22, a longitudinal web 24 and about a catwalk 26 is arranged. Along the longitudinal web 24 can additionally run lines that are not shown here, such as drainage pipes, power lines, etc.

Während der Durchführung des erfindungsgemäßen Verfahrens werden die Medienrohre 16 zunächst im Bereich des Schachts 14 abgetrennt. Sie werden dann im Zuge der Sanierung der Tunnelröhre 10 nach entsprechender Demontage der Verstrebungen 22 von ihrem Auflager 20 abgehoben und mittels einer Aufhängung 28, wie sie in Figur 3 gezeigt ist, aufgehängt. Die Aufhängung 28 ist auch in der Figur 1 dargestellt.During the implementation of the method according to the invention, the media tubes 16 are first separated in the region of the shaft 14. They are then in the course of renovation of the tunnel tube 10 after appropriate disassembly of the braces 22 lifted from its support 20 and by means of a suspension 28, as in FIG. 3 shown is hung up. The suspension 28 is also in the FIG. 1 shown.

Nach dem Aufhängen der Medienrohre 16 kann die Tunnelsohle 30 mit einer Abdichtung ausgekleidet werden. Nach entsprechender Auskleidung werden dann Schienen 32 in der Tunnelröhre 10 ohne Durchdringung der Sohlenabdichtung 30 verlegt, wie dies später anhand der Figuren 5 und 6 erläutert werden wird. Anschließend wird dann eine Gewölbeabdichtung 34 aufgebracht, so daß die gesamte Tunnelröhre 10 abgedichtet ist.After suspending the media tubes 16, the tunnel sole 30 can be lined with a seal. After appropriate lining then rails 32 are laid in the tunnel tube 10 without penetration of the sole seal 30, as will be described later with reference to FIGS. 5 and 6 will be explained. Subsequently, a vault seal 34 is then applied, so that the entire tunnel tube 10 is sealed.

Auf den im Bereich der Tunnelsohle angeordneten Schienen 32 werden Rohrstücke 36 eingeschoben. Diese Rohrstücke 36 weisen bezogen auf die Tunnelröhre einen kleineren Durchmesser auf. Im hier dargestellten Ausführungsbeispiel sind sie ebenfalls kreisrund, wie dies beispielhaft in Figur 4 gezeigt ist. Die Rohrstücke 36 weisen eine Länge auf, die ein einfaches Einbringen in den Schacht 14 ermöglicht. Dort werden die einzelnen Rohrstücke 36, die in üblicher Weise aus Stahlbeton bestehen, auf den Schienen 32 abgelegt und mittels einer gegenüber dem Eingangsbereich der zu sanierenden Tunnelröhre 10 im Schacht 14 angeordneten Hydraulikpresse 38 in die Tunnelröhre eingeschoben. Dabei stützen sich die einzelnen Rohrstücke 36 aneinander ab, so daß aus den Rohrstücken 36, die in Pfeilrichtung a in die Tunnelröhre 10 eingeschoben werden, eine Innenauskleidung entsteht. Während des Einschiebens der Rohrstücke 36 in die Tunnelröhre 10 werden die Medienrohre 16 auf entsprechenden Auflagern 20 aufgenommen. Die Auflager 20 bestehen aus Rollenlagern, so daß die Medienrohre 16 während des Vorschubs der Rohrstücke 36 auf dem Auflager entlang gleiten können.On the arranged in the region of the tunnel sole rails 32 pipe sections 36 are inserted. These tube pieces 36 have a smaller diameter relative to the tunnel tube. In the embodiment shown here, they are also circular, as exemplified in FIG. 4 is shown. The pipe pieces 36 have a length that allows easy insertion into the shaft 14. There, the individual pipe sections 36, which consist of reinforced concrete in the usual way, placed on the rails 32 and inserted by means of a relative to the entrance of the tunnel tube 10 to be rehabilitated in the shaft 14 arranged hydraulic press 38 in the tunnel tube. In this case, the individual pipe sections 36 are supported on each other, so that from the pipe sections 36 which are inserted in the direction of arrow a in the tunnel tube 10, an inner lining is formed. During the insertion of the pipe sections 36 into the tunnel tube 10, the media tubes 16 are received on corresponding supports 20. The supports 20 are made of roller bearings, so that the media tubes 16 can slide along the support 36 during the advance of the pipe sections.

Nach vollständigem Einschieben sämtlicher Rohrstücke wird der Zwischenraum zwischen den eingebrachten Rohrstücken 36 und der Tunnelröhre 10 mit einem geeigneten Füllmaterial verfüllt, wobei hier üblicherweise ein vergleichsweise dünnflüssiger und damit gut pumpbarer Fließbeton durch auf Umfang der Rohrstücke 36 angeordnete Öffnungen (die in den Figuren nicht näher dargestellt sind) hinterfüllt wird. Nach dem Hinterfüllen werden die Öffnungen dieser Bohrungen mit einer Schraube, einem Stopfen oder einem anderen geeigneten Verschlußmittel wieder dicht verschlossen.After complete insertion of all pipe sections of the space between the inserted pipe sections 36 and the tunnel tube 10 is filled with a suitable filler, in which case usually a comparatively low-viscosity and thus easy pumpable fluid concrete by arranged on the circumference of the pipe sections 36 openings (not shown in the figures are) backfilled. After backfilling the openings of these holes with a screw, a plug or other suitable closure means are sealed again.

Schließlich werden die Medienrohre 16 nach Fertigstellung des aus den Rohrstücken 36 bestehenden Innenrohres wieder mit der restlichen außen liegenden Medienleitung innerhalb des Schachtes 14 verbunden.Finally, the media tubes 16 are connected after completion of the existing of the pipe sections 36 inner tube with the rest of the outside media line within the shaft 14.

Anhand der Figuren 5 und 6 wird im einzelnen erläutert, wie die Schienen 32 durchdringungsfrei in der Abdichtung 30 angeordnet werden können.Based on FIGS. 5 and 6 will be explained in detail how the rails 32 can be arranged without penetration in the seal 30.

Hierzu weist die aus einer ansonsten stabilen Kunststoffolie bestehende Abdichtung 30 in dem Bereich, in dem die Schienen 32 verlegt werden sollen, ein Kunststofformteil 40 auf, welches einen tiefgezogenen Doppeldorn 42 umfasst. Die Außenoberfläche des Doppeldorns 42 ist, wie in Figur 6 gezeigt, geriffelt bzw. gerillt. Das gesamte Bauteil 40 weist eine gewölbte Form auf, so daß es sich an die Krümmung der zu sanierenden Tunnelröhre anpaßt (vgl. Figur 5). In der Tunnelröhre sind an der Stelle, in welcher der Doppeldorn 42 eingesetzt wird, zwei Kernbohrungen 44 angeordnet. In diese Kernbohrungen reichen die Doppeldorne 42, wo sie mittels eines Vergußmörtels 46 fest vergossen werden. Aufgrund der Oberflächenstruktur der Doppeldorne 42 haben diese nach entsprechendem Aushärten des Vergußmörtels einen besonders guten Halt. Das beispielsweise aus Polyethylen bestehende Formteil wird dann mit der Kunststoffolie 30 fest verbunden, das heißt verschweißt.For this purpose, the existing of an otherwise stable plastic film seal 30 in the area in which the rails 32 are to be laid, a plastic molding 40, which comprises a deep-drawn double mandrel 42. The outer surface of the double mandrel 42 is, as in FIG FIG. 6 shown, grooved or grooved. The entire component 40 has a curved shape, so that it adapts to the curvature of the tunnel tube to be rehabilitated (see. FIG. 5 ). In the tunnel tube, two core holes 44 are arranged at the point in which the double mandrel 42 is used. In these core holes reach the double mandrels 42, where they are sealed by means of a grout 46. Due to the surface structure of the double mandrels 42, these have a particularly good hold after appropriate curing of the grout. The existing example of polyethylene molding is then firmly connected to the plastic film 30, that is welded.

Bei einer Tunnelabdichtung werden grundsätrzlich alle Stöße miteinander dicht verschweißt. So entsteht eine vollflächige Rundumabdichtung, die systemrelevant ist. Durch Vorsehen des Formteils bleibt dieses System auch für die Verankerung der Schienen erhalten.In the case of a tunnel seal, all joints are basically welded together tightly. This creates a full-surface all-round seal that is system-relevant. By providing the molded part, this system is also retained for the anchoring of the rails.

In die entsprechenden Doppeldorne 42 werden dann die Befestigungsmittel z.B. in Form von Gewindestangen 48 über ein geeignetes Vergußmaterial eingegossen. Bei dem entsprechenden Vergußmaterial kann es sich beispielsweise um Epoxydharz handeln. Nach entsprechendem Festwerden der Verbindung kann auf das Befestigungsmittel die auf einer entsprechenden Stahlplatte 50 angeordnete Schienen 32 in in Figur 5 dargestellter Art und Weise verschraubt werden. Die Schiene 32 ist vorzugsweise auf der Stahlplatte aufgeschweißt.In the corresponding double mandrels 42, the fastening means are then poured in the form of threaded rods 48 via a suitable potting material. The corresponding potting material may be, for example, epoxy resin. After a corresponding solidification of the connection can be arranged on the fastening means arranged on a corresponding steel plate 50 rails 32 in in FIG. 5 be screwed illustrated manner. The rail 32 is preferably welded onto the steel plate.

Figur 5 zeigt darüber hinaus noch ein Segment eines Rohrstücks 36, aus dem ersichtlich ist, daß längs des Rohrstücks 36 in dem Bereich, in welchem es auf der Schiene 32 aufliegt, eine Gleitfläche 52 vorgesehen ist. Diese Gleitfläche besteht aus einem Material mit guten Gleiteigenschaften, beispielsweise einem entsprechende Kunststoff. Mittig ist im Bereich der Gleitfläche 52 in vorbestimmten Abständen jeweils eine Durchführung 54 angeordnet, die zur Schmierung dient. Die Durchführung 54 kann später mit einer dichtenden Schraube 56 verschlossen werden. FIG. 5 moreover shows a segment of a pipe section 36, from which it can be seen that along the pipe section 36 in the region in which it rests on the rail 32, a sliding surface 52 is provided. This sliding surface consists of a material with good sliding properties, such as a corresponding plastic. In the middle of the sliding surface 52 at predetermined intervals each have a passage 54 is arranged, which serves for lubrication. The bushing 54 can later be closed with a sealing screw 56.

Der zwischen der Tunnelröhre 10 und dem Rohrstück 36 liegende Ringraum 58 wird nach entsprechendem Einbau der Rohrstücke 36 mit einem geeigneten Füllmaterial verfüllt.The annular space 58 lying between the tunnel tube 10 and the pipe section 36 is filled with a suitable filling material after appropriate installation of the pipe sections 36.
