Abstract (en)
The rings are built up from successive reinforced-concrete segments in the peripheral direction. Each ring (2) contains one or more peripheral undercut recesses (3), which are filled with concrete on site to increase the strength. Each ring can have one undercut near its inner edge, the recesses in adjacent rings being combined to form a single undercut one. The recesses can be of dovetail section, and adjacent rings can be screwed together via profiled sheet-metal components inserted in the recesses before filling with concrete. The concrete used for filling can be reinforced.
Abstract (de)
Eine Tunnelauskleidung ist mit in Tunnellängsrichtung hintereinander angeordneten Tübbingringen (1) ausgeführt, die jeweils aus in Tunnelumfangsrichtung hintereinander angeordneten segmentförmigen Tübbingen (2) aus Stahlbeton aufgebaut sind. Eine nahezu allen Belastungen standhaltende Ausführungsform ist dadurch gewährleistet, daß jeder Tübbingring (1) an seiner Innenmantelfläche mit wenigstens einer umlaufenden, hinterschnittenen Aussparung (3) versehen ist und die Aussparungen (3) mit Ortbeton verfüllt sind. <IMAGE>
