Description
die durch die Erhöhung des Widerstandsmomentes ermöglichte Wanddickenverringerung des Mantels verwirklichen, ohne zu große Wanddickenunterschiede zwischen den Stoßf!ansehen und dem Mantel in Kauf nehmen zu müssen.the reduction in the wall thickness of the jacket made possible by the increase in the section modulus without seeing too great differences in wall thickness between the buttocks and the jacket to have to accept.
In weiterer Ausbildung der Erfindung sind in den Eckbereichen die Stoßflansche mit den verdickten Mantelabschnitten verbindende Versteifungsrippen vorgesehen, die eine zusätzliche Biegeentlastung der Stoßflansche bewirken.In a further embodiment of the invention, the butt flanges with the thickened ones are in the corner areas Reinforcing ribs connecting jacket sections are provided, which provide additional bending relief of the Effect butt flanges.
Erfindungsgemäß ist schließlich die gegebenenfalls durch Versteifungsrippen unterteilte rinnenförmige Mantelvertiefung in an sich bekannter Weise mit einer durckfesten Füllmasse, z.B. Beton, ausgefüllt, und es sind zwischen den Seitenwänden der rinnent'örmigen Mantelvcrtiefung eingeklemmte Armierungsstäbe vorgesehen, die parallel zur Zylinderachse gerichtete Druckkräfte übertragen. Durch diese Armierungsstäbe ergibt sich eine einwandfreie Kraftübertragung von Umfangsflansch zu Umfangsflansch, und es können auch die parallel zur Zylinderachse verlaufenden Versteifungsrippen dünner ausgeführt werden, weil eine Überbrückung der Mantelveriiefung durch die Stäbe und die Betonfüllung vorhanden ist und somit der Tübbingmantel mitträgt, wenn im Schildvortrieb gearbeitet wird.Finally, according to the invention, the channel-shaped, optionally subdivided by stiffening ribs Shell recess filled in a manner known per se with a pressure-resistant filling compound, e.g. concrete, and there are clamped reinforcing bars between the side walls of the channel-shaped shell recess, which are directed parallel to the cylinder axis Transferring compressive forces. These reinforcing bars result in a perfect power transmission from circumferential flange to circumferential flange, and the stiffening ribs running parallel to the cylinder axis can also be made thinner, because the mantle groove is bridged by the bars and the concrete filling and thus the lining of the segment supports when work is carried out in shield tunneling.
In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt, und zwar zeigtIn the drawing, the subject matter of the invention is shown in one embodiment, namely indicates
