Abstract

Der Sicherheitstübbing ist aus mehreren Schichten aufgebaut. Die äußerste, dem Boden zugewandte Schicht besteht aus hochfestem Beton, bevorzugt mit Fasern bewehrt. Die innerste, dem Tunnelinneren zugewandte Schicht besteht aus einem Brandschutzbeton, zum Beispiel einem Faserbeton, in dem auch Polymerfasern enthalten sind. Zwischen der innersten und der äußersten Schicht befindet sich mindestens eine weitere Schicht, die verglichen mit normalem Beton elastisch oder unelastisch deformierbar ist. Der Sicherheitstübbing bietet gegenüber Explosionen eine erhöhte Sicherheit gegen eine starke Beschädigung des Bauwerkes.The safety tubbing is made up of several layers. The outermost, the floor facing layer is made of high-strength concrete, preferably reinforced with fibers. The innermost, the tunnel interior facing layer consists of a fire-resistant concrete, for example, a fiber concrete, in which polymer fibers are also included. Between the innermost and the outermost layer is at least one further layer that is elastically or inelastically deformable compared to normal concrete. The safety tubbing offers increased safety against explosions against severe damage to the structure.

Description

Technisches GebietTechnical area

Die Erfindung betrifft den Bau von gegen Explosionen unempfindlicheren Tunneln mithilfe von Tübbingen.The The invention relates to the construction of less sensitive to explosions Tunneling by means of segments.

Stand der TechnikState of the art

Um Tunnel gegen Explosionen unempfindlicher zu machen, wird im allgemeinen die Tunnelwand entsprechend verstärkt. Besteht der Tunnel aus Tübbingen, sind die einzelnen Tübbinge dicker und damit auch schwerer und nicht mehr so gut zu handhaben.Around Tunnel insensitivity to explosions generally becomes reinforced the tunnel wall accordingly. Is the tunnel out? tubbing, are the individual segments thicker and therefore heavier and not so easy to handle.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es, einen Tübbing anzugeben, der bei gleicher Schutzwirkung deutlich dünner und leichter ist, als ein herkömmlicher Tübbing mit Explosionsschutzwirkung.task the invention is to specify a tubbing, with the same protective effect is significantly thinner and lighter than a conventional one tubbing with explosion protection effect.

Darstellung der ErfindungPresentation of the invention

Die Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst.The The object is specified by that in the characterizing part of claim 1 Characteristics solved.

Wesentliches Merkmal der Erfindung ist hierbei, den Tübbing, aus dem der Tunnel zusammengesetzt ist, vom Tunnelinneren zum Tunneläußeren hin aus mehreren Schichten aufzubauen, die jede eine unterschiedliche Hauptfunktion ausübt.essential Feature of the invention is here, the tubbing, composed of the tunnel is, from the interior of the tunnel to the outside of the tunnel out of several layers each having a different main function.

Die innerste, dem Tunnelinneren zugewandte Schicht besteht aus Brandschutzbeton, zum Beispiel einem Faserbeton, in dem auch Polymerfasern enthalten sind.The the innermost layer facing the interior of the tunnel consists of fire-resistant concrete, for example, a fiber concrete in which also contain polymer fibers are.

Die äußerste, dem Bodenmaterial zugewandte Schicht besteht aus einem hochfesten Beton, bevorzugt mit Fasern bewehrt.The utmost, the soil material facing layer consists of a high-strength Concrete, preferably reinforced with fibers.

Zwischen der innersten Schicht und der äußersten Schicht befindet sich mindestens eine weitere Schicht, die verglichen mit normalem Beton elastisch oder unelastisch deformierbar ist. Diese Schicht absorbiert teilweise die Energie einer Explosion und gibt die verbleibende Energie über eine größere Fläche an die äußerste Schicht des Tunnels weiter. Die Schicht muß hierfür verglichen mit Beton deutlich stärker komprimierbar sein.Between the innermost layer and the outermost Layer is at least one more layer compared is deformable elastically or inelastically with normal concrete. This layer partially absorbs the energy of an explosion and gives the remaining energy over a larger area to the outermost layer the tunnel continues. The layer must be much more compressible compared to concrete be.

Als solche Schicht ist bevorzugt ein gashaltiger und damit leichter komprimierbare Feststoff geeignet, der dem Tübbing auch eine gewisse Stabilität verleiht und die äußere und innere Schicht miteinander verbindet. Ein solcher Feststoff wäre zum Beispiel Porenbeton.When such layer is preferably a gas-containing and thus lighter Compressible solid suitable, which also gives the tubbing a certain stability and the outer and inner layer connects with each other. Such a solid would be, for example Aerated concrete.

Es ist auch möglich, für diese Schicht z.B. eine hinreichend komprimierbare Flüssigkeit oder ein hinreichend komprimierbares Gel zu verwenden (auch Wasser ist z.B. verglichen mit Metallen um ungefähr den Faktor 50 besser komprimierbar und läßt sich bei 1000 bar um 5% komprimieren!), das nach der Herstellung des Tunnels aus den Tübbingen in einen durch Stützen/Abstandshalter freigehaltenen Hohlraum zwischen äußerster Schicht und innerster Schicht des Tübbings eingefüllt wird.It is possible, too, for this Layer e.g. a sufficiently compressible liquid or sufficient to use compressible gel (for example, water is also compared with metals at about the factor 50 is better compressible and can be reduced by 5% at 1000 bar compress!), after the preparation of the tunnel from the tubbing in one by supports / spacers vacant cavity between outermost layer and innermost layer of the tubbing filled becomes.

Statt einer Flüssigkeit oder einem Gel kann ein solcherfrei gehaltener Zwischenraum auch mit verdichtetem Sand oder anderem verdichtetem Schüttgut gefüllt sein, das immer noch genügend Hohlräume aufweist, um bei einer Explosion noch deutlich mehr verdichtet zu werden.Instead of a liquid or a gel, such a gap kept free can also filled with compacted sand or other compacted bulk material, that still has enough cavities, to be condensed much more in an explosion.
