Abstract

The rings are built up from successive reinforced-concrete segments in the peripheral direction. Each ring (2) contains one or more peripheral undercut recesses (3), which are filled with concrete on site to increase the strength. Each ring can have one undercut near its inner edge, the recesses in adjacent rings being combined to form a single undercut one. The recesses can be of dovetail section, and adjacent rings can be screwed together via profiled sheet-metal components inserted in the recesses before filling with concrete. The concrete used for filling can be reinforced.

Description

Die Erfindung betrifft eine Tunnelauskleidung mit in Tunnellängsrichtung hintereinander angeordneten Tübbingringen, die jeweils aus in Tunnelumfangsrichtung hintereinander angeordneten segmentförmigen Tübbingen aus Stahlbeton aufgebaut sind.The invention relates to a tunnel lining with segment rings arranged one behind the other in the longitudinal direction of the tunnel, each of which is constructed from segmented segments made of reinforced concrete arranged one behind the other in the circumferential direction of the tunnel.

Eine solche Tunnelauskleidung in Form eines aus der Praxis allgemein bekannten Tübbingausbaus hat bei schwierigen Baugrundverhältnissen, insbesondere in Verbindung mit Grundwasser, wo die NÖT (Neue Österreichische Tunnelbauweise) an ihre Grenzen stößt, ihre Vorteile: Der Tübbingausbau eignet sich sowohl für nicht bindige als auch für bindige Böden, sofern diese eine nicht allzu fließfähige Konsistenz aufweisen. In Lockergestein und bei anstehendem Grundwasser werden die Tübbinge hinter einer im Schildvortrieb fahrenden Tunnelbohrmaschine eingebaut. Die Stützung des Gebirges und die Absperrung des Grundwassers durch den Schild muß beim Auffahren des Tunnels sofort vom Tübbingausbau übernommen werden. Tübbinge müssen demzufolge eine Soforttragwirkung und gegebenenfalls eine Sofortdichtigkeit besitzen. In Festgestein können Tübbinge als Alternative zum Spritzbetonverfahren hinter Voll- bzw. Teilschnittmaschinen eingebaut werden. In beiden Fällen läßt sich durch die Verwendung von Tübbingen eine einschalige Tunnelauskleidung erstellen, die zugleich Sicherung und Ausbau ist.Such a tunnel lining in the form of a segmental lining that is generally known in practice has its advantages in difficult ground conditions, especially in connection with groundwater, where the NTM (New Austrian Tunneling Construction) reaches its limits: The segmental lining is suitable for both non-binding and for cohesive soils, provided they have a consistency that is not too fluid. In loose rock and in the presence of groundwater, the segments are installed behind a tunnel boring machine driving in the shield. The support of the mountains and the shielding of the groundwater by the shield must be taken over immediately by the tubbing extension when the tunnel is opened. Tubbings must therefore have an immediate load-bearing effect and, if necessary, an immediate seal. As an alternative to the shotcrete method, segments can be installed in solid rock behind full or partial cutting machines. In both cases, the use of tubbing can be used to create a single-layer tunnel lining that is both securing and removing.

Tübbinge sind Fertigteilelemente, die heute zumeist aus Stahlbeton gefertigt werden. Die Tunnelröhre besteht aus einzelnen Tübbingsteinen, deren Anzahl u.a. vom Tunneldurchmesser abhängig ist. Die Tübbingringe werden um eine halbe Steinlänge gegeneinander versetzt eingebaut, um abdichtungstechnisch schwierige Fugenkreuzungen zu vermeiden. Die heute übliche Art der Tübbinggestaltung ist der Block- bzw. Kassettentübbing. Beim Kassettentübbing wird im Gegensatz zum Blocktübbing, um Gewicht zu sparen und die Verschraubung der Steine untereinander zu erleichtern, der Querschnitt im mittleren Steinbereich stark reduziert. Die Tunnelauskleidung soll einwirkende Lasten ohne größere Deformationen aufnehmen, d.h. sie muß für alle, dem Tunnelbau entsprechenden Lastfälle dimensioniert werden können. Vom fertiggestellten Bauwerk sind Bodenlasten, Grundwasser, Eigengewicht und Betriebslasten bzw. Verkehrslasten aufzunehmen. Im Bauzustand treten Transportzustände, Vortriebslasten, Verpreßdruck und Einflüsse aus Druckluft auf. Die vorstehende Auflistung der einwirkenden Lasten zeigt deutlich, daß der Ausbau überwiegend auf Drucknormalkräfte und Biegemomente hin zu bemessen ist. Lediglich beim Lastfall Druckluft kann bei geringen Firstüberdeckungen die im Tunnel gehaltene Druckluft zu einem Aufheben der Drucknormalkräfte führen; dies kann unter Umständen bestimmend für die Bemessung sein. Eventuell entstehende Zugbeanspruchungen in der Tunnelauskleidung treten aber nur im Bauzustand auf. Längsfugen können in diesen Bereichen mit vorgespannten Schraubverbindungen dicht gehalten werden. Die im Tübbingring vorhandenen Drucknormalkräfte und die Vortriebspressenkräfte gewährleisten ein Zusammendrücken der Längs- und Ringfugen. Auf diese Weise kommen die in die Fugen eingelegten Dichtungen voll zur Wirkung. Bei Bauteilen mit Wasserdruck von innen, z.B. Druckwasserstollen, können in Abhängigkeit von den Bodensteifigkeiten hohe Zugnormalkräfte entstehen. Eine Dichtigkeit, vor allem der Längsfugen, kann dann mit herkömmlichen Tübbingauskleidungen nicht mehr erreicht werden. Hohe Zugbeanspruchungen in der Tunnelauskleidung können mit den derzeit üblichen Stahlbetontübbingsystemen nicht bewältigt werden, da die Dichtigkeit in den Längsfugen nicht gewährleistet werden kann.Tubbings are precast elements that are mostly made of reinforced concrete today. The tunnel tube consists of individual segment stones, the number of which depends, among other things, on the tunnel diameter. The tubbing rings are installed offset against each other by half a stone length to make them difficult to seal Avoid joint crossings. The usual type of tubbing design is block or cassette tubbing. In contrast to block tubbing, in cassette tubbing, in order to save weight and facilitate screwing the stones together, the cross section in the central stone area is greatly reduced. The tunnel lining should absorb acting loads without major deformations, ie it must be able to be dimensioned for all load cases corresponding to tunnel construction. Soil loads, groundwater, dead weight and operating or traffic loads are to be absorbed from the completed structure. In the construction state, transport states, jacking loads, compression pressure and influences from compressed air occur. The above list of the acting loads clearly shows that the expansion is predominantly based on normal pressure forces and bending moments. The compressed air held in the tunnel can only cancel the normal pressure forces in the case of compressed air with low ridge coverages; Under certain circumstances, this can be decisive for the design. Any tensile stresses that may arise in the tunnel lining only occur in the construction state. In these areas, longitudinal joints can be kept tight with prestressed screw connections. The normal pressure forces in the segment ring and the jacking press forces ensure that the longitudinal and ring joints are compressed. In this way, the seals inserted in the joints come into full effect. For components with water pressure from the inside, such as pressurized water tunnels, high normal tensile forces can arise depending on the floor stiffness. Tightness, especially the longitudinal joints, can then no longer be achieved with conventional segmental lining. High tensile stresses in the tunnel lining cannot be managed with the currently used reinforced concrete segment systems, as the tightness in the longitudinal joints cannot be guaranteed.

Ebenso bereiten sehr weiche, bindige bzw. fließfähige Böden mit einer Tübbingauskleidung große Probleme, da die angenommene elastische Bettung des Bodens durch annhähernd hydrostatische Bodenverhältnisse nicht mehr gegeben ist.Likewise, very soft, cohesive or flowable soils with segmental lining pose great problems, since the assumed elastic bedding of the soil is no longer possible due to the almost hydrostatic soil conditions.

Aufgabe der Erfindung ist es, eine Tunnelauskleidung anzugeben, die neben den oben beschriebenen Einsatzmöglichkeiten auch den Einsatz in sehr weichen bindigen Böden erlaubt und in Fällen starker Zugbeanspruchung der Tunnelschale eingesetzt werden kann.The object of the invention is to provide a tunnel lining which, in addition to the possible uses described above, also allows use in very soft, cohesive soils and can be used in cases of high tensile stress on the tunnel shell.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß jeder Tübbingring an seiner Innenmantelfläche mit wenigstens einer umlaufenden, hinterschnittenen Aussparung versehen ist und die Aussparungen mit Ortbeton verfüllt sind.The solution to this problem according to the invention is that each segment ring is provided on its inner lateral surface with at least one circumferential, undercut recess and the recesses are filled with in-situ concrete.

Wie oben schon ausgeführt worden ist, wirken während der Bauphase auf die Sicherung bzw. den Ausbau vornehmlich Drucknormalkräfte und Biegemomente, die aus verformungsabhängigen Bodenlasten und gegebenenfalls anstehendem Grundwasser resultieren. Hierzu werden die Tübbinge mit plattenbalkenähnlicher Struktur und den Aussparungen eingebaut; sie sind dann in der Lage, den Ausbruchquerschnitt zu stützen und zu sichern. Der verstärkte Balkenbereich gewährleistet eine einwandfreie Übertragung der Ringkräfte, da die Längsfuge durch die vorhandene Steinstärke von beispielsweise etwa 40 cm konstruktiv sinnvoll ausgebildet werden kann. Die Ortbetonringe in den entsprechend bemessenen Aussparungen übernehmen jedenfalls die Übertragung von auftretenden Zugnormalkräften und verhindern ein Aufgehen der Längsfugen.As has already been explained above, during the construction phase, the securing or expansion is primarily affected by normal pressure forces and bending moments, which result from deformation-dependent soil loads and possibly existing groundwater. For this purpose, the segments are installed with a structure similar to slab beams and the recesses; they are then able to support and secure the excavation cross-section. The reinforced beam area ensures perfect transmission of the ring forces, since the longitudinal joint can be designed in a constructive manner due to the existing stone thickness of about 40 cm, for example. The in-situ concrete rings in the correspondingly dimensioned recesses in any case take over the transmission of normal train forces and prevent the longitudinal joints from opening.

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. So ist nach einer bevorzugten Ausführungsform die Anordnung so zu treffen, daß jeder Tübbingring im Bereich seiner beiden Innenringkanten mit je einer hinterschnittenen Aussparung versehen ist und sich die benachbarten Aussparungen der nebeneinanderliegenden Tübbingringe zu einer Aussparungsnut ergänzen; insoweit ist es besonders empfehlenswert, wenn die Aussparungen bzw. Aussparungsnuten einen schwalbenschwanzförmigen Querschnitt aufweisen. Bei dieser Ausführungsform sind auch die Ringfugen besonders abgedichtet. Durch die schwalbenschwanzförmige Ausbildung der Aussparungen kann vorhandener Außenwasserdruck, der sich im Bereich der Verbundfuge aufbauen kann, vom Gesamtquerschnitt aufgenommen und abgetragen werden. Wird der Tunnel in sehr weichem, bindigen Boden aufgefahren, können mit dem Bau des Tübbingringes Blechprofilabschnitte in die Aussparungen in Höhe der Längsfugen gelegt werden, um eine sofortige Biegesteifigkeit des Tübbingringes zu erzielen. Die Blechprofilabschnitte werden mit den Tübbingen bzw. gegebenenfalls gegeneinander verschraubt. In einem nachlaufenden Arbeitsgang werden die Aussparungen dann gemäß den statischen Erfordernissen bewehrt und ausbetoniert.There are several possibilities for the further configuration within the scope of the invention. According to a preferred embodiment, the arrangement must be such that each segment ring is provided with an undercut recess in the area of its two inner ring edges and the adjacent recesses of the segment rings lying next to one another complement to form a recess groove; In this respect, it is particularly recommended if the recesses or recess grooves have a dovetail cross section. In this embodiment, the ring joints are also particularly sealed. Due to the dovetail-shaped design of the recesses, existing external water pressure, which can build up in the area of the composite joint, can be absorbed and removed from the overall cross-section. If the tunnel is opened in very soft, cohesive soil, sheet metal sections can be placed in the recesses at the height of the longitudinal joints with the construction of the segment ring in order to achieve immediate bending rigidity of the segment ring. The sheet profile sections are screwed to the segments or, if necessary, against each other. In a subsequent work step, the recesses are then reinforced and concreted in accordance with the structural requirements.

Im Rahmen der beschriebenen Maßnahmen kann es sich nach einer weiterhin bevorzugten Ausführungsform empfehlen, die Anordnung so zu treffen, daß der die Aussparungen ausfüllende Beton als Außenrippen einer in Tunnellängsrichtung durchlaufenden Innenauskleidungsschale aus Ortbeton ausgeführt sind. Dabei kann die Innenauskleidungsschale eine zusätzliche Bewehrung aufweisen. Da hierbei die Tübbingringfugen nachträglich ausbetoniert werden, kann der versetzte Einbau der Tübbingringe untereinander entfallen, da der Ortbeton der Innenauskleidungsschale die Dichtung in den Bereichen der Längsfugen übernimmt; der Einbau der Tübbinge wird somit für die Baustelle erleichtert.In the context of the measures described, it can be recommended, in accordance with a further preferred embodiment, to make the arrangement in such a way that the concrete filling the recesses is in the form of outer ribs of an inner lining shell made of in-situ concrete and running in the longitudinal direction of the tunnel. The inner lining shell can have additional reinforcement. Since the segment ring joints are subsequently concreted, the staggered installation of the segment rings can be done with each other omitted, since the in-situ concrete of the inner lining shell takes over the seal in the areas of the longitudinal joints; the installation of the segments is thus made easier for the construction site.

Die in den Figuren dargestellten Tunnelauskleidungen weisen zunächst jeweils in Tunnellängsrichtung hintereinander angeordnete Tübbingringe 1 auf, die jeweils aus in Tunnelumfangsrichtung hintereinander angeordneten segmentförmigen Tübbingen 2 aus Stahlbeton aufgebaut sind. Jeder Tübbingring 1 ist an seiner Innenmantelfläche mit wenigstens einer umlaufenden hinterschnittenen Aussparung 3 versehen und die Aussparungen 3 sind mit Ortbeton verfüllt. Bei den Ausführungsformen nach den Fig. 3 und 4 sind die hinterschnittenen schwalbenschwanzförmigen Aussparungen 3 in der Mitte eines Tübbingringes 1 angeordnet. Bei den Ausführungsformen nach den Fig. 1, 5 und 6 ist dagegen jeder Tübbingring 1 im Bereich seiner beiden Innenringkanten mit je einer hinterschnittenen Aussparung 3 versehen, und zwar derart, daß sich die benachbarten Aussparungen 3 der nebeneinanderliegenden Tübbingringe 1 zu einer Aussparungsnut 4 mit schwalbenschwanzförmigem Querschnitt ergänzen.The tunnel linings shown in the figures initially have segment rings 1 arranged one behind the other in the longitudinal direction of the tunnel, each of which is constructed from reinforced concrete segment-shaped segments 2 arranged one behind the other in the circumferential direction of the tunnel. Each segment ring 1 is provided on its inner lateral surface with at least one circumferential undercut recess 3 and the recesses 3 are filled with in-situ concrete. In the embodiments according to FIGS. 3 and 4, the undercut dovetail-shaped recesses 3 are arranged in the middle of a segment ring 1. In the embodiments according to FIGS. 1, 5 and 6, however, each segment ring 1 is provided with an undercut recess 3 in the area of its two inner ring edges, in such a way that the adjacent recesses 3 of the segment segments 1 lying next to one another form a recess groove 4 with a dovetail-shaped Complete cross section.

Fig. 2 zeigt, daß benachbarte Tübbinge 2 eines Tübbingringes 1 durch vor der Ortbetonverfüllung in die Aussparungen 3 eingebrachte Blechprofilabschnitte 5 miteinander verschraubt sein können.Fig. 2 shows that adjacent segments 2 of a segment ring 1 can be screwed together by means of sheet metal profile sections 5 introduced into the recesses 3 before the in-situ concrete filling.

In den Figuren ist nicht erkennbar, daß der in den Aussparungen 3 befindliche Ortbeton bewehrt sein kann. In den Figuren ist weiterhin nicht dargestellt, daß sich zwischen dem Gebirge und den Tübbingringen ein Ringraum befinden kann, der nach oder während der Montage der Tübbinge mit Mörtel, Beton oder Kunstboden ausgefüllt werden kann.It cannot be seen in the figures that the in-situ concrete located in the recesses 3 can be reinforced. Furthermore, the figures do not show that there can be an annular space between the mountains and the tubbing rings, which can be filled with mortar, concrete or synthetic floor after or during the assembly of the tubbing rings.

Die Fig. 4 und 6 schließlich zeigen noch eine besonders hoch beanspruchbare Ausführungsform, die sich dadurch auszeichnet, daß der die Aussparungen 3 ausfüllende Beton als Außenrippen 6 einer in Tunnellängsrichtung durchlaufenden Innenauskleidungsschale 7 aus Ortbeton ausgeführt sind. Daneben gewährleistet die durchgehend betonierte Innenauskleidungsschale 7 die Dichtigkeit der Stahlbetonverbundbauweise in besonderem Maße, insbesondere bei der Verwendung von Tübbingen mit mittig liegender Aussparung. Diese Innenauskleidungsschale 7 kann, was ebenfalls nicht dargestellt ist, eine zusätzliche Bewehrung aufweisen.4 and 6 finally show a particularly heavy-duty embodiment, which is characterized in that the concrete filling the recesses 3 are designed as outer ribs 6 of an inner lining shell 7 running in the longitudinal direction of the tunnel and made of in-situ concrete. In addition, the continuously concreted inner lining shell 7 ensures the tightness of the reinforced concrete composite construction to a particular degree, especially when using segments with a central recess. This inner lining shell 7, which is also not shown, can have additional reinforcement.
