Abstract

For driving a tunnel in water-bearing, unsupported ground, a shield is used in combination with a tight tunnel lining. The shield has a pressure-resistant working chamber in which the excavating tool works. The working chamber is arranged in the front part of the shield, is open towards the heading face and is tightly closed against the rear tunnel. The water accumulating on the rock side is caught and held in this working chamber. The solid excavated material from the working chamber is pumped out of the working chamber with the water, if need be while feeding or pumping over additional water, and is conveyed out of the tunnel.

Description

Verfahren zum Vortreiben eines Tunnels unter VerwendungMethod of driving a tunnel using

eines Schildes mit flüssigkeitsgefüllter Arbeitskammer Die Erfindung betrifft ein Verfahren zum Vortreiben eines Tunnels unter Verwendung eines Schildes mit einer im Vorderteil des Schildes angeordneten, gegen die Ortsbrust offenen, gegen den rückwärtigen Tunnel dicht geschlossenen, druckfesten, mit Flüssigkeit gefüllten Arbeitskammer in Verbindung mit einem dichten Tunnelausbau.of a shield with a liquid-filled working chamber The invention relates to a method of driving a tunnel using a shield with one arranged in the front part of the shield and open to the face, against the rear tunnel tightly closed, pressure-resistant, with liquid filled working chamber in connection with a tight tunnel lining.

Es ist bekannt, Schilde, die eine mit Flüssigkeit gefüllte Arbeitskammer aufweisen, bei Vortrieben in nichtstandfestem wasserführendem Boden zu verwenden. Die Aufgabe der Flüssigkeitsfüllung ist bei derartigen Schilden die Stützung der Ortsbrust, d.h. ein unkontrolliertes Nachbrechen des Bodens an der abgebauten Ortsbrust zu verhindern.It is known to have shields that have a liquid-filled working chamber have to be used for excavations in unstable water-bearing soil. The task of the liquid filling in shields of this type is to support the Face, i.e. uncontrolled breaking of the soil on the excavated face to prevent.

In standfestem Gebirge braucht die Ortsbrust nicht gestützt zu werden. Es hatte deshalb bisher auch keinen Sinn, eine Arbeitskammer mit Flüssigkeitsfüllung zu verwenden. Bei Vortrieben in wasserführendem standfestem Gebirge wurde bisher, soweit eine offene Wasserhaltung möglich war, das Wasser an der Ortsbrust aufgefangen und in offenen Gerinnen abgeführt. Das anfallende Wasser und seine Ableitung führten zu Störungen und Verschmutzungen in Ortsbrust - wie auch im weiteren Tunnelbereich. An der Ortsbrust bei der Bodengewinnung anfallender Staub behinderte die Arbeit und verursachte schlechte Arbeitsbedingungen.The face does not need to be supported in stable mountains. So there was no point in having a working chamber filled with liquid to use. When driving in water-bearing, stable rock, it was previously as far as an open dewatering was possible, the water was collected on the face and discharged in open channels. The resulting water and its discharge led to disturbances and soiling in the face - as well as in the further tunnel area. The work was hampered by the dust accumulating on the face when the soil was reclaimed and caused poor working conditions.

Mit der Weiterentwicklung des Tunnelausb2us durch einschalige dichte Ausbaukonstruktionen und mit der Entwicklung wirksamer Dichtungen zwischen Schild und Aus kleidung ergab sich als Aufgabenstellung auch für den Tunnelbau in standfestem Boden die Entwicklung eines Tunnelvortriebverfahrens, das den gesamten rückwärtigen Tunnelraum von äußerem Gebirgswasser freihält.With the further development of the tunnel construction through single-shell density Extension constructions and with the development of effective seals between shield and lining resulted as a task for the tunnel construction in stable Soil the development of a tunnel driving method that covers the entire rear Keeps the tunnel space free from external mountain water.

Die Aufgabe wird durch das im kennzeichnenden Teil des Hauptanspruches beschriebene Verfahren gelöst.The task is indicated by that in the characterizing part of the main claim described method solved.

Durch das erfindungsgemäße Verfahren wird es möglich, einen Tunnel im standfesten wasserführenden Gebirge trocken vorzutreiben0 Der Schild mit dichter Schottwand und der dichte Ausbau bilden eine durchgehende dichte Innenschale des Tunnels, die das Tunnelinnere gegen drückendes Wasser von außen schützt Das an der Ortsbrust anfallende Wasser wird in der Arbeitskammer aufgefangen und über ein Leitungssystem abgepumpt oder sogar als Transportmedium für den Abtransport des gewonnenen Materials genutzte Der Abbau des Bodens erfolgt staubfrei und schafft damit günstige Arbeitsbedingungen.The method according to the invention makes it possible to create a tunnel to be driven dry in stable water-bearing mountains0 The shield with denser The bulkhead wall and the tight expansion form a continuous, tight inner shell of the Tunnels that protect the inside of the tunnel against pressing water from the outside Any water from the face is collected in the working chamber and via a pipe system pumped out or even as a transport medium for the removal of the recovered material used The soil is dismantled dust-free and thus creates favorable working conditions.

Das erfindungsgemäße Verfahren wird in einer Systemzeichnung Fig. 1 erläutert: Zum Abbau des wasserführenden Bodens 1 wird ein Schild 2 verwendet, dessen Abbauwerkzeug 3 in einer durch eine dichte Schottwand 4 abgetrennten Arbeitskammer 5 arbeitet. Die Arbeitskammer ist mit Wasser gefüllt oder fängt das von der Ortsburst einströmende Wasser auf. Über Leitungen 6, 7 ist das Wasser umpumpbar.The method according to the invention is shown in a system drawing Fig. 1 explained: A shield 2 is used to dismantle the water-bearing soil 1, its excavation tool 3 in a working chamber separated by a tight bulkhead 4 5 works. The working chamber is filled with water or catches it from the local burst incoming water. The water can be pumped around via lines 6, 7.

Mit dem umgepumpten Wasser kann der abgebaute Boden je nach Feinheit des gewonnenen Materials direkt oder nach entsprechender Aufbereitung in einem Brecher 8 hydraulisch nach draußen gefördert werden. Der Tunnel innenraum 9 kann druckluft frei gehalten werden durch eine wirksame Schildschwanzdichtung 10 und eine dichte Auskleidung, im Beispiel durch dichte einschalige Tübbings 11.With the circulated water, the excavated soil can, depending on its fineness of the recovered material directly or after appropriate processing in a crusher 8 can be hydraulically conveyed to the outside. The tunnel interior 9 can pressurized air are kept free by an effective shield tail seal 10 and a tight Lining, in the example by dense single-shell segments 11.
