Description

Die Erfindung betrifft einen Doppeltunnel aus zwei parallelen unmittelbar aneinander angrenzenden Einzelröhren. - Der erfindungsgemäße Doppeltunnel eignet sich insbesondere für zwei zueinander parallele Bahnstrecken, beispielsweise U-Bahn- oder S-Bahn-Strecken. Zweckmäßigerweise befindet sich in jeder der beiden Einzelröhren jeweils eine Bahnstrecke. Grundsätzlich liegt es jedoch auch im Rahmen der Erfindung, den Doppeltunnel als Straßentunnel einzusetzen.The invention relates to a double tunnel of two parallel directly adjacent individual tubes. - The double tunnel according to the invention is particularly suitable for two mutually parallel railway lines, for example, subway or S-Bahn routes. Conveniently, in each of the two individual tubes in each case a railway line. In principle, however, it is also within the scope of the invention to use the double tunnel as a road tunnel.

Bei aus der Praxis bekannten Doppeltunneln der eingangs genannten Art gehen die Wandauskleidungen der beiden Einzelröhren im Verbindungsbereich der Einzelröhren in eine einzige Mittelwand über. Für den Übergang der Wandauskleidungen in diese Mittelwand sind sowohl im oberen Verbindungsbereich als auch im unteren Verbindungsbereich Y-förmige Übergangselemente vorgesehen. Zwischen diesen Y-förmigen Elementen sind Mittelwandelemente angeordnet. Die im Verbindungsbereich vorgesehenen Y-förmigen Elemente müssen aufgrund der dort aufzunehmenden beachtlichen Lasten besonders stabil ausgeführt werden. Das ist aufwendig und kostspielig. Die weiteren Mittelwandelemente, die zwischen den Y-förmigen Elementen angeordnet sind, bilden eine einzige Wand, die im Mittelbereich die Seitenwandung sowohl der ersten Einzelröhre als auch der zweiten Einzelröhre ist. Wenn es in einer der beiden Einzelröhren zu einem Brand kommt und die Mittelwand bzw. die Mittelwandelemente aufgrund der Brandeinwirkung beschädigt oder zerstört werden, findet stets eine Beeinträchtigung beider Einzelröhren statt. Die zweite, zunächst nicht vom Brand betroffene Einzelröhre kann dann in der Regel auch nicht mehr als Fluchtweg dienen.In known from practice double tunnels of the type mentioned, the wall linings of the two individual tubes go in the connection region of the individual tubes in a single center wall. For the transition of the wall linings in this middle wall Y-shaped transition elements are provided both in the upper connection region and in the lower connection region. Between these Y-shaped elements middle wall elements are arranged. The provided in the connection area Y-shaped elements must be carried out particularly stable due to the considerable loads to be absorbed there. This is expensive and expensive. The further center wall elements, which are arranged between the Y-shaped elements, form a single wall, which is the side wall of both the first single tube and the second single tube in the central region. If a fire occurs in one of the two individual tubes and the central wall or the middle wall elements are damaged or destroyed due to the effect of fire, the two individual tubes are always impaired. The second, initially not affected by the fire single tube then usually can not serve as an escape route.

Ein Beispiel eines Doppeltunnels mit y-förmigen Verbindungselementen ist von DE-A-24 08 038 bekannt.An example of a double tunnel with y-shaped connecting elements is known from DE-A-24 08 038.

Fernerhin ist es bekannt, zwei in der Regel im Querschnitt kreisförmige Einzelröhren mit einigem Abstand voneinander anzuordnen. Wenn bei dieser Ausführungsform Fluchtwege oder Notausstiege zwischen den beiden Einzelröhren vorgesehen werden sollen, müssen in aufwendiger Weise Querschläge zwischen den Einzelröhren hergestellt werden. In Abhängigkeit von den geologischen und hydrologischen Verhältnissen sind dazu oftmals sehr aufwendige Maßnahmen erforderlich.Furthermore, it is known to arrange two generally circular in cross section individual tubes with some distance from each other. If escape routes or emergency exits between the two individual tubes are to be provided in this embodiment, cross-passages between the individual tubes must be produced in a complex manner. Depending on the geological and hydrological conditions often very complex measures are required.

Demgegenüber liegt der Erfindung das technische Problem zugrunde, einen Doppeltunnel der eingangs genannten Art anzugeben, bei dem die vorstehend geschilderten Nachteile vermieden werden und bei dem vor allem Flucht- und Rettungswege auf einfache Weise geschaffen werden können und bei dem beispielsweise im Brandfall eine sichere Fluchtmöglichkeit gegeben ist.In contrast, the invention, the technical problem of providing a double tunnel of the type mentioned above, in which the above-mentioned disadvantages are avoided and in the escape and rescue routes can be created in a simple way and in which, for example, given a safe escape in the event of fire is.

Zur Lösung dieses technischen Problems lehrt die Erfindung einen Doppeltunnel aus zwei parallelen unmittelbar aneinandergrenzenden Einzelröhren,
wobei die beiden Einzelröhren durch eine vertikale Mittelwand voneinander getrennt sind,
und wobei sich die Mittelwand aus zwei parallelen aneinandergrenzenden Seitenwänden zusammensetzt und dass zwischen diesen die Mittelwand bildenden Seitenwänden eine Mittelfuge vorgesehen ist, wobei jede Seitenwand einer der beiden Einzelröhren zugeordnet ist und mit den weiteren Wandelementen dieser Einzelröhre die Wandauskleidung der Einzelröhre bildet und wobei die Wandauskleidung der Einzelröhren bildenden Wandelemente Tübbings sind und dass die beiden Seitenwände aus Tübbings bestehen.To solve this technical problem, the invention teaches a double tunnel consisting of two parallel, directly adjacent individual tubes,
wherein the two individual tubes are separated by a vertical middle wall,
and wherein the middle wall is composed of two parallel adjoining side walls, and that a central joint is provided between these side walls forming the middle wall, each side wall being associated with one of the two individual tubes, and forms the wall lining of the single tube with the other wall elements of this single tube and wherein the wall lining of the individual tubes forming wall elements are tubbing and that the two side walls consist of tubbing.

Erfindungsgemäß sind also gleichsam zwei voneinander unabhängige separate Einzelröhren vorhanden. Jede der beiden Einzelröhren weist auch im Verbindungsbereich eine ihr zugeordnete eigene Seitenwand auf, wobei die beiden im Verbindungsbereich aneinandergrenzenden Seitenwände der beiden Einzelröhren die Mittelwand des Doppeltunnels bilden.According to the invention, so to speak two separate separate individual tubes are available. Each of the two individual tubes also has its own associated side wall in the connection area, the two side walls of the two individual tubes adjoining each other in the connection area forming the middle wall of the double tunnel.

Es liegt im Rahmen der Erfindung, dass für die Wandauskleidung der Einzelröhren Stahlbetontübbings eingesetzt werden.It is within the scope of the invention that reinforced concrete tubbings are used for the wall lining of the individual tubes.

Nach sehr bevorzugter Ausführungsform der Erfindung weist jede der beiden Einzelröhren, abgesehen von dem Mittelwandbereich, einen kreisförmigen oder ellipsenförmigen Querschnitt auf. Kreisförmiger oder ellipsenförmiger Querschnitt meint hier auch einen im Wesentlichen kreisförmigen oder im Wesentlichen ellipsenförmigen Querschnitt. Es liegt im Rahmen der Erfindung, dass die Wandauskleidung der Einzelröhren den kreisförmigen und/oder ellipsenförmigen Querschnitt bildet. Dieser kreisförmige Querschnitt und/oder ellipsenförmige Querschnitt geht im Mittelwandbereich jeweils in eine vertikale Seitenwand der jeweiligen Einzelröhre über. Die beiden Seitenwände bzw. die daraus gebildete Mittelwand bildet also gleichsam eine vertikale Sekante bezüglich des kreisförmigen Querschnitts und/oder ellipsenförmigen Querschnitts der Einzelröhren.According to a very preferred embodiment of the invention, each of the two individual tubes, except for the middle wall region, has a circular or elliptical cross-section. Circular or elliptical cross-section here also means a substantially circular or substantially elliptical cross-section. It is within the scope of the invention that the wall lining of the individual tubes forms the circular and / or elliptical cross-section. This circular cross section and / or elliptical cross section merges into a vertical side wall of the respective individual tube in the middle wall region. The two side walls or the middle wall formed therefrom thus forms, so to speak, a vertical one Secant with respect to the circular cross section and / or elliptical cross section of the single tubes.

Befingt durch die äußeren Lasten werden die beiden Einzelröhren in der senkrechten Mittelfuge zusammengedrückt. Es liegt dabei im Rahmen der Erfindung, dass durch schräg zur Mittelfuge hin ausgebildete Längsfugen im Mittelwandbereich eine Pressung in der Mittelfuge erzeugt wird, so dass ein Hineinwandern der Tübbingsteine der Mittelfuge in die Einzelröhren verhindert wird. Die Mittelfuge wird nachfolgend auch als Pressfuge bezeichnet. Es liegt weiterhin im Rahmen der Erfindung, dass die Mittelfuge im oberen und unteren Bereich durch Spannelemente stabilisiert wird. Durch zusätzliche Schubnocken, Topf- und Nockenkonstruktionen in der Mittelfuge kann eine Schubkraftübertragung zur Begrenzung einer gegenseitigen Vertikalverschiebung der Röhren ermöglicht werden.Due to the external loads, the two individual tubes are compressed in the vertical middle joint. It is within the scope of the invention that a pressure in the middle joint is generated by obliquely to the central joint formed longitudinal joints in the middle wall region, so that a Hineinwandern the Tübbingsteine the central joint is prevented in the individual tubes. The middle joint is also referred to below as a press joint. It is also within the scope of the invention that the middle joint in the upper and lower regions is stabilized by clamping elements. Additional thrust cams, cup and cam designs in the middle joint may allow thrust transfer to limit mutual vertical displacement of the tubes.

Nach sehr bevorzugter Ausführungsform, der im Rahmen der Erfindung ganz besondere Bedeutung zukommt, sind über der Mittelwand den Mittelwandbereich abdichtende Dichtelemente vorgesehen. Die Dichtelemente sind dabei über dem Mittelwandbereich so angeordnet, dass die Mittelwand bzw. die Pressfuge zwischen den beiden Seitenwänden gegen das Eindringen von Feuchtigkeit abgedichtet ist. Vorzugsweise sind die Dichtelemente in oberhalb der Mittelwand angeordneten Tübbings integriert. Oberhalb der Mittelwand angeordnete Tübbings meint dabei auch Tübbings, die einen Abschnitt aufweisen, der zur Bildung der Mittelwand bzw. zur Bildung einer der beiden Seitenwände beiträgt. Nach der vorgenannten bevorzugten Ausführungsform der Erfindung übernehmen also Tübbings, die die Wandauskleidung der Einzelröhren bilden, die Funktion der Abdichtung für die Mittelwand bzw. für die Pressfuge. Es liegt dabei im Rahmen der Erfindung, dass sich beim Zusammensetzen der Tübbings mit integrierten Dichtelementen ein Dichtrahmen über der Mittelwand bzw. über der Pressfuge bildet. Vorzugsweise entsteht beim Zusammenfügen der mit Dichtelementen ausgerüsteten Tübbings eine bündige Verbindung der Dichtelemente. - Nach sehr bevorzugter Ausführungsform der Erfindung sind auch unter der Mittelwand abdichtende Dichtelemente vorgesehen. Es liegt dabei im Rahmen der Erfindung, dass diese Dichtelemente in unterhalb der Mittelwand angeordneten Tübbings integriert sind. Auch hier bilden die mit den Dichtelementen ausgerüsteten Tübbings gleichsam einen Dichtrahmen unterhalb der Mittelwand.After a very preferred embodiment, the special role in the context of the invention, the middle wall region sealing sealing elements are provided over the middle wall. The sealing elements are arranged above the middle wall region so that the middle wall or the press joint between the two side walls is sealed against the ingress of moisture. Preferably, the sealing elements are integrated in above the middle wall arranged Tübbings. Tübbings arranged above the middle wall also means tubbings which have a section which is used for forming the middle wall or for forming contributes to one of the two side walls. After the aforementioned preferred embodiment of the invention thus take over tubbing, which form the wall lining of the individual tubes, the function of the seal for the middle wall or for the press joint. It is within the scope of the invention that forms a sealing frame on the center wall or on the press joint when assembling the tubbing with integrated sealing elements. Preferably, when assembling the segments equipped with sealing elements, a flush connection of the sealing elements is produced. - According to a very preferred embodiment of the invention sealing sealing elements are provided under the middle wall. It is within the scope of the invention that these sealing elements are integrated in below the middle wall arranged Tübbings. Again, the equipped with the sealing elements tubbing as it forms a sealing frame below the center wall.

Nach sehr bevorzugter Ausführungsform, der im Rahmen der Erfindung ganz besondere Bedeutung zukommt, sind in der Mittelwand Durchbrüche vorgesehen. Bei den Durchbrüchen handelt es sich insbesondere um Fluchtwege bzw. Rettungswege, die die beiden Einzelröhren des Doppeltunnels miteinander verbinden. Es liegt im Rahmen der Erfindung, dass für einen solchen Durchbruch in der Mittelwand eine entsprechende Durchbruchöffnung sowohl in der einen als auch in der anderen Seitenwand vorgesehen sein muss. Die Durchbruchöffnungen haben beispielsweise quadratischen oder rechteckförmigen Querschnitt. Der Durchbruch kann durch eine Tür oder dergleichen verschlossen sein. - Nach einer Ausführungsform der Erfindung sind zur Herstellung von Durchbrüchen in der Mittelwand Seitenwandelemente aus den Seitenwänden entfernbar. Wenn eine Durchbruchöffnung in einer Seitenwand also einen rechteckförmigen oder quadratischen Querschnitt hat, ist ein entsprechend geformtes Seitenwandelement mit rechteckförmigem oder quadratischem Querschnitt aus der betreffenden Seitenwand entfernbar.According to a very preferred embodiment, which is of very particular importance within the scope of the invention, apertures are provided in the middle wall. The breakthroughs are, in particular, escape routes or escape routes which connect the two individual tubes of the double tunnel. It is within the scope of the invention that for such a breakthrough in the middle wall, a corresponding breakthrough opening must be provided both in the one and in the other side wall. The openings have, for example, square or rectangular cross-section. The breakthrough may be closed by a door or the like. - According to one embodiment of the invention are for the production of Breakthroughs in the middle wall Sidewall elements removable from the side walls. Thus, if a breakthrough opening in a side wall has a rectangular or square cross section, a correspondingly shaped side wall element with a rectangular or square cross section can be removed from the respective side wall.

Der Erfindung liegt die Erkenntnis zugrunde, dass ein erfindungsgemäßer Doppeltunnel auf relativ einfache und wenig aufwendige Weise hergestellt werden kann und dass nichtsdestoweniger die bei den aus dem Stand der Technik bekannten Doppeltunnels vorhandenen Nachteile effektiv vermieden werden können, wenn die erfindungsgemäße Lehre nach Patentanspruch 1 verwirklicht wird. Zunächst können auf sehr einfache Weise Durchbrüche zwischen den beiden unmittelbar benachbarten Einzelröhren eingerichtet werden, die als Flucht- oder Rettungswege dienen. Ein solcher Durchbruch kann grundsätzlich an jeder beliebigen Stelle der Mittelwand vorgesehen werden, also unabhängig von den geologischen oder hydrologischen Gegebenheiten der Umgebung. Die beiden den Doppeltunnel bildenden Einzelröhren stützen sich in überraschend effektiver Weise gegenseitig ab. Mit anderen Worten sind aufwendige Bewehrungsmaßnahmen oder Abstützungsmaßnahmen gegenüber dem über dem Doppeltunnel angeordneten Erdreich nicht erforderlich. So kann auch auf aufwendig hergestellte Spezialtübbings zur Aufnahme sehr großer Lasten weitgehend verzichtet werden. Zu betonen ist auch, dass der Verbindungsbereich zwischen den beiden Einzelröhren bzw. die Pressfuge zwischen den beiden Einzelröhren auf einfache Weise mit geeigneten Dichtelementen abgedichtet werden kann. Von erfindungswesentlicher Bedeutung ist die Tatsache, dass in einem in einer Einzelröhre auftretenden Brandfall die zweite benachbarte Einzelröhre weitgehend unbeeinträchtigt bleibt. Somit kann die zweite Einzelröhre problemlos als Fluchtweg bzw. Fluchttunnel genutzt werden.The invention is based on the finding that a double tunnel according to the invention can be produced in a relatively simple and inexpensive manner and that nonetheless the disadvantages present in the double tunnels known from the prior art can be effectively avoided if the teaching according to the invention according to claim 1 is realized , First, breakthroughs between the two directly adjacent individual tubes can be set up in a very simple way, which serve as escape or rescue routes. Such a breakthrough can in principle be provided at any point of the middle wall, that is independent of the geological or hydrological conditions of the environment. The two individual tubes forming the double tunnel are mutually supported in a surprisingly effective manner. In other words, costly reinforcement measures or support measures are not required with respect to the soil arranged above the double tunnel. So can be largely dispensed with elaborately manufactured special tubbing to accommodate very large loads. It should also be stressed that the connection area between the two individual tubes or the press joint between the two individual tubes can be sealed in a simple manner with suitable sealing elements. Of essential importance to the invention is the fact that in a fire occurring in a single tube the second adjacent single tube remains largely unimpaired. Thus, the second single tube can be easily used as an escape route or escape tunnel.

Vorzugsweise und im Ausführungsbeispiel werden die beiden Seitenwände 4, 5 möglichst dicht nebeneinander angeordnet und wird die Breite der Pressfuge 10 daher möglichst gering gehalten. In Fig. 1 sind Spannelemente 11 erkennbar, mit denen die beiden Seitenwände 4, 5 gegeneinander verspannt sind und der Abstand zwischen den beiden Seitenwänden 4, 5 daher sehr gering gehalten wird. Mit der Verspannung wird eine Verdrehung über die Kontaktfläche reduziert, je nach Grad der Vorspannung. Das führt auch zu einer Minimierung der Fugenbreite der Pressfuge 10. Damit wird auch die Mindestanpressung der unten noch erwähnten Dichtrahmen untereinander gewährleistet.Between the middle wall 3 forming side walls 4, 5, a press joint 10 is provided. Preferably, and in the embodiment, the two side walls 4, 5 are arranged as close as possible side by side and the width of the press joint 10 is therefore kept as low as possible. In Fig. 1, clamping elements 11 can be seen, with which the two side walls 4, 5 are braced against each other and the distance between the two side walls 4, 5 is therefore kept very low. With the tension becomes a twist Reduced over the contact surface, depending on the degree of bias. This also leads to a minimization of the joint width of the press joint 10. This also ensures the minimum contact pressure of the below-mentioned sealing frame with each other.

Vorzugsweise und im Ausführungsbeispiel sind über der Mittelwand 3 bzw. über der Pressfuge 10 den Mittelwandbereich 8 bzw. die Pressfuge 10 abdichtende Dichtelemente 12 vorgesehen. Zweckmäßigerweise sind die Dichtelemente 12 in Tübbings integriert, welche Tübbings die Wandauskleidung der Einzelröhren 1, 2 bilden bzw. die Mittelwand 3 bilden. Vorzugsweise weist jeder außenliegende Tübbing einen umlaufenden geschlossenen Tübbingdichtrahmen auf. Es liegt im Rahmen der Erfindung, dass beim Aneinanderfügen der Tübbings bzw. Spezialtübbings 9 zur Ausbildung der Wandauskleidung der Einzelröhren 1, 2 bzw. zur Ausbildung der Mittelwand 3 ein zusammenhängender Dichtrahmen 14 entsteht. Im Ausführungsbeispiel nach Fig. 1 ist durch das Aneinanderfügen der Tübbings bzw. Spezialtübbings 9 ein zusammenhängender Dichtrahmen 14 für beide Einzelröhren 1, 2 gebildet, wobei dieser Dichtrahmen 14 sowohl oberhalb des Mittelwandbereiches 8 bzw. oberhalb der Pressfuge 10 als auch unterhalb der Mittelwand 3 bzw. unterhalb der Pressfuge 10 verläuft.Preferably, and in the exemplary embodiment, sealing sealing elements 12 are provided above the center wall 3 or above the press joint 10, the middle wall region 8 and the press joint 10, respectively. Expediently, the sealing elements 12 are integrated into segments, which segments form the wall lining of the individual tubes 1, 2 or form the middle wall 3. Each outer tubbing preferably has a circumferential closed tubing sealing frame. It is within the scope of the invention that, when joining the tubbings or special tubbings 9 to form the wall lining of the individual tubes 1, 2 or to form the middle wall 3, a coherent sealing frame 14 is created. In the embodiment according to FIG. 1, a continuous sealing frame 14 is formed for both single tubes 1, 2 by joining the tubbings or special tubbings 9, wherein this sealing frame 14 both above the middle wall region 8 or above the press joint 10 and below the middle wall 3 and . Runs below the press joint 10.

Es liegt aber auch im Rahmen der Erfindung, dass jede Einzelröhre 1, 2 für sich einen geschlossenen Dichtrahmen 14 aufweist. Dies ist in den Figuren nicht dargestellt worden. Bei dieser Ausführungsform weist die Mittelwand 3 also gleichsam zwei parallele Dichtungen auf. Eine Verspannung der Mittelwand 3 ist bei dieser Ausführungsform nicht erforderlich. Vom Traggefüge und von der Abdichtung bilden beide Einzelröhren 1, 2 autarke Systeme, die lediglich im Bereich der Mittelwand 3 aneinandergedrückt werden.However, it is also within the scope of the invention that each individual tube 1, 2 has a closed sealing frame 14 for itself. This has not been shown in the figures. In this embodiment, the middle wall 3, so to speak, two parallel seals. A tension the middle wall 3 is not required in this embodiment. From the support structure and the seal both single tubes 1, 2 form self-sufficient systems, which are pressed together only in the region of the middle wall 3.

Nach einer sehr bevorzugten Ausführungsform der Erfindung sind in der Mittelwand 3 Durchbrüche 13 vorgesehen, die als Flucht- bzw. Rettungswege dienen. Ein solcher Durchbruch 13 ist in Fig. 2 dargestellt. Es ist erkennbar, dass sowohl die Seitenwand 4 als auch die Seitenwand 5 einen entsprechenden Durchbruch 13 aufweisen muss.According to a very preferred embodiment of the invention 3 breakthroughs 13 are provided in the middle wall, which serve as escape or rescue routes. Such a breakthrough 13 is shown in Fig. 2. It can be seen that both the side wall 4 and the side wall 5 must have a corresponding opening 13.
