Description
Brustschild beim Tunnel- oder Stollenvortrieb Die Erfindung betrifft einen aus einzelnen übereinandergreifenden Blechplatten bestehenden Brustschild zur Sicherung der Ortsbrust beim Tunnel- und Stollenvortrieb. Sie besteht darin, daß der Schild aus Blechplatten besonderer Form zusammengesetzt ist, und zwar aus solchen, die mit einem senkrecht zur Schildebene stehenden oberen Flansch versehen sind. Die Form der Platten ist an sich bekannt, und zwar beispielsweise bei Spundwandeisen; neu ist indessen die Anwendung solcher Profile für die Herstellung von Brustschilden beim Tunnel- und Stollenvortrieb. Der Flansch, durch den die Schildteile in sich wirkungsvoll versteift werden, bietet eine günstige Angriffsfläche bei dem Eintreiben der Schilde in das Erdreich. Die durch den Flansch erzielte höhere Formfestigkeit der Blechplatten ermöglicht, diese entsprechend dünner zu wählen, was wiederum das Eintreiben der Platten erleichtert.Breastplate in tunnel or gallery driving The invention relates to a breastplate consisting of individual overlapping sheet metal plates to secure the face when driving tunnels and galleries. It consists in that the shield is composed of sheet metal plates of a special shape, namely from those that are provided with an upper flange perpendicular to the plane of the shield are. The shape of the plates is known per se, for example in the case of sheet piling iron; What is new, however, is the use of such profiles for the manufacture of breast shields when driving tunnels and galleries. The flange through which the shield parts are in are effectively stiffened, offers a favorable attack surface when driving the shields in the ground. The higher dimensional stability achieved by the flange of the sheet metal plates enables them to be selected thinner accordingly, which in turn makes the Driving in the plates is made easier.
Die Zeichnung veranschaulicht die Erfindung an einem Ausführungsbeispiel. Vor den die Vortriebsbleche b tragenden Lehrbögen a, welche beispielsweise durch Stempel s gegen die Auskleidung c des vorzutreibenden Tunnels abgestützt sind, sind in an sich üblicher Weise die zur Sicherung der jeweiligen Ortsbrust dienenden, aus Blechplatten bestehenden Schilde f angeordnet: Die Blechplatten f sind erfindungsgemäß mit einem sie versteifenden, senkrecht zur Schildebene stehenden oberen Flansch e ver= sehen, gegen welchen auch die zum Eintreiben der Schilde in das Erdreich dienenden Werkzeuge angesetzt werden.The drawing illustrates the invention using an exemplary embodiment. In front of the teaching sheets a carrying the jacking plates b, which, for example, go through Punches s are supported against the lining c of the tunnel to be driven in a customary manner those used to secure the respective face, Shields f consisting of sheet metal plates are arranged: The sheet metal plates f are according to the invention with a stiffening upper flange perpendicular to the plane of the shield e ver = see against which also those for driving the shields into the ground serving tools are used.
