Abstract (en)

For the continuous tunneling work through loose rock, using ring segments to be assembled into rings (1), in the first step with extended leader presses (7) and withdrawn telescope presses (8) and retracted press shields (11), the telescope presses (8) are extended and the leader presses (7) are withdrawn. In the next step, after the press shield (11) has been advanced and positioned at the tunnel wall, the leader presses (7) are extended for the next advance. The telescope presses (8) are operated to be followed by the assembly of a further ring (1).

Abstract (de)

Zum kontinuierlichen Vortreiben und gleichzeitigen Ausbauen eines in Lockergestein zu erstellenden Tunnels mit aus Tübbingsegmenten zusammengesetzten Tübbingringen (1) wird mit einer Schildvortriebsmaschine gearbeitet, die einen Vorlaufschild (2), einen über Vorlaufpressen (7) mit dem Vorlaufschild (2) verbundenen und über Teleskoppressen (8) mit gegenüber den Vorlaufpressen (7) vergrößertem Hub am Tübbingausbau (9) abstützbaren Mittelschild (3) mit radial vor- und zurückbewegbaren Preßschilden (11) und einen mit dem Mittelschild (3) verbundenen Nachlaufschild (4) aufweist. In einer ersten Stufe werden ausgehend von ausgefahrenen Vorlaufpressen (7), eingefahrenen Teleskoppressen (8) und zurückgezogenen Preßschilden (11) zum Vortrieb die Teleskoppressen (8) ausgefahren und die Vorlaufpressen (7) eingefahren. In einer nachfolgenden zweiten Stufe werden nach Ausfahren und Festsetzen der Preßschilde (11) an der Tunnelwandung die Vorlaufpressen (7) für den weiteren Vortrieb ausgefahren und nach Vorziehen der Teleskoppressen (8) die Tübbingsegmente eines weiteren Tübbingringes (1) eingebaut. <IMAGE>
