   Schraubentöpfe,   an deren Stelle auch Keile oder ähnliche Vorrichtungen benutzt werden können, die Balken sofort nach der Bewegung des Schildes um eine Balkenbreite einzeln um die Decke der Abdeckplatte 10 gehoben. In Fig. 4 schleift hiebei die Abdeckplatte unmittelbar auf der Dichtungsschicht, die von entsprechender Widerstandsfähigkeit sein muss. In Fig. 5 sind besondere Zwischenlagen 28 von der Breite der Balken vorgesehen, die die   Dichtungsflächen schützen. Selbstverständtich   können auch Bleche dazwischengelegt werden, die den   Vorteil haben, dass sie   laufend aneinandergenietet werden können und dass hiedurch eine Bewegung der Bleche im Sinne des Schildvortriebes verhindert ist.

   Screw pots, in the place of which wedges or similar devices can also be used, the bars individually lifted around the ceiling of the cover plate 10 immediately after the movement of the shield by a bar width. In Fig. 4, the cover plate rubs directly on the sealing layer, which must be of appropriate resistance. In Fig. 5, special spacers 28 are provided the width of the beams to protect the sealing surfaces. Of course, metal sheets can also be placed in between, which have the advantage that they can be continuously riveted to one another and that this prevents the sheets from moving in the direction of shield propulsion.
