Zusammenfassung:A collapsible device for the erection of a pressed monolithic lining in underworkings wherein a pressing member, along its perimeter, is made of separate parts linked through hinge joints connected to drives acting in radial directions, and in which case the end portions of the parts adjoining the hinge-joints connected to the drives are adapted for rotation or function as toggle mechanisms. This makes it possible to develop an adequate pressure force in the radial directions.
