Der Erfindung liegt die Aufgabe zugrunde, einen kontinuierlichen Vortrieb ohne Zwangspausen für den Tübbingeinbau zu ermöglichen.The invention has for its object a continuous Propulsion without mandatory breaks for segment installation enable.
Zur Lösung dieser Aufgabe lehrt die Erfindung in verfahrensmäßiger Hinsicht daß die mit dem doppelten Hub der Vorlaufpressen ein- und ausfahrenden Teleskoppressen in der ersten Stufe unter Überdrücken der Vorlaufpressen für den weiteren Vortrieb ausgefahren werden. - Nach bevorzugter Ausführungsform zum Einbauen eines Tübbingringes, wie bekannt, nur die zugeordneten Teleskoppressen vorgezogen, d.h. die übrigen Teleskoppressen in Anlage an den übrigen Tübbingsegmenten belassen.To achieve this object, the invention teaches in procedural terms Considering that the double stroke of the Leading presses in and out telescopic presses in the first stage by overpressing the lead presses for the further drive can be extended. - After preferred Embodiment for installing a segment ring, as known only the assigned telescopic presses are preferred, i.e. the other telescopic presses in contact with the others Leave the segment segments.
Die Erfindung geht von der Erkenntnis aus, daß durch die zusätzliche, vom Tübbingausbau unabhängige Möglichkeit des Abfangens der Vortriebskräfte über die Preßschilde auch ein kontinuierlicher Vortrieb durchgeführt werden kann und dabei für den Tübbingringeinbau keine Zwangspausen erforderlich sind. Im Ergebnis führt die Erfindung so zu einem schnelleren und kostengünstigeren Vortrieb und Ausbau eines Tunnels. The invention is based on the knowledge that through the additional possibility of the Interception of the driving forces on the press shields also continuous tunneling can be carried out and no mandatory breaks are required for installing the segment ring are.

Gegenstand der Erfindung ist, wie schon gesagt, auch eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens, wobei die mit Hilfe von Preßstempeln radial vor- und zurückbewegbaren Preßschilde zusätzlich geführt sind; hier besteht die Erfindung darin, daß die Preßschilde mit zusätzlichen Führungsstäben in Führungssäulen geführt und mit Hilfe von Keilpressen festsetzbar sind, deren Keilstücke zwischen den freien Enden der Führungsstäbe und Schildsteifewiderlagern angeordnet sind. Bei dieser Ausführungsform wird mit einfachen Mitteln eine störungsfreie. Ableitung der Vortriebskräfte auf die Tunnelwandung gewährleistet; Zwängungen und Verklemmungen sind sicher unterbunden. Im allgemeinen ist es vollkommen ausreichend, wenn lediglich zwei horizontal vor- und zurückbewegbare Preßschilde vorgesehen sind. Vorzugsweise sind die Keilpressen senkrecht zur Längsachse des Mittelschildes angeordnet, und zwar insbesondere so, daß je zwei Keilpressen in entgegengesetzten Richtungen gegeneinander arbeiten, wodurch sich die entsprechenden Druckkräfte gleichsam aufheben. Im übrigen sollte der Mittelschild längs des Aussparungsrandes seiner Preßschilde eine umlaufende selbstreinigende Dichtung aufweisen, die von der Innenseite des Mittelschildes her ersetzbar ist. Mittelschild und Nachlaufschild könnten grundsätzlich zu einem einzigen Schildteil miteinander vereinigt sein. Zwecks besserer Lenkbarkeit der Schildvortriebsmaschine empfiehlt es sich jedoch, den Mittelschild und den Nachlaufschild über Koppelpressen miteinander zu verbinden. Jedenfalls wird man die Anordnung zweckmäßigerweise so treffen, daß der Mittelschild mit seinem vorderen Ende im Vorlaufschild angeordnet ist und der Nachlaufschild einen Durchmesser kleiner als der Durchmesser des Vorlaufschildes aufweist. Insoweit ist es günstig, wenn der Nachlaufschild mit seinem vorderen Ende im Mittelschild angeordnet ist.The subject of the invention, as already said, is also one Device for carrying out the method according to the invention, the radially protruding with the help of and retractable press shields are additionally performed; here the invention is that the press shields with additional guide rods in guide columns and can be fixed with the help of wedge presses, the wedge pieces between the free ends of the guide rods and Counter stiffeners are arranged. In this embodiment becomes trouble-free with simple means. Dissipation of the driving forces on the tunnel wall guaranteed; Squeezes and deadlocks are safely prevented. In general, it is quite sufficient if only two press shields that can be moved horizontally back and forth are provided. The wedge presses are preferably arranged perpendicular to the longitudinal axis of the central shield, and in particular so that two wedge presses in opposite Directions work against each other, which makes cancel the corresponding pressure forces. Furthermore the middle shield should be along the recess edge its press shields a circumferential self-cleaning seal have that from the inside of the middle shield is replaceable. Middle shield and trailing shield could basically to a single shield part with each other be united. For better maneuverability of the shield tunneling machine however, it is recommended to use the middle shield and the trailing plate together via coupling presses connect. In any case, the arrangement will be useful so that the middle shield with its front End in the lead sign is arranged and the trailing plate has a diameter smaller than the diameter of the leader plate. In this respect, it is favorable if the trailing plate with its front end is arranged in the middle shield.
