Abstract: In a process and a winding device for lining elongated spaces such as tunnels or ducts of circular and non-circular cross-sections, especially for canal and tunnel construction band is employed. Tubes with various diameters and different cross-sections, but mainly with circular and egg-shaped cross-sections, may be created from the band by the winding device.

Abstract: A tunnel support machine for use in a tunnel forming system wherein the tunnel support machine follows a tunnel-driving machine during the driving operation. Through the operation of the tunnel support machine, a preferably inaccessible tunnel cavity formed by the tunnel-driving machine is supported by a profiled ribbon which is continuously fed to the tunnel support machine and continuously spirally wound thereby into a support tube which lines and reinforces the tunnel cavity. Supply and discharge lines extending rearwardly from the tunnel-driving machine generally in the central area of the tunnel cavity connect to longitudinally extending bores provided in a stationary cylindrical part of a rotary bushing of the tunnel support machine.

Abstract: A bracing device for a self-advancing shield tunnelling machine for tunnel construction comprising a control shield within which is mounted a cutting unit, and at least two bracing shields each having a closed circumferential wall construction which are connected together by feed cylinders, the bracing shields being able to be radially braced with the tunnel wall independently of each other by bracing elements fixed thereon. The bracing elements are composed of elastic pressure hoses positioned around the closed circumferential bracing shield walls. The circumferences of the bracing elements can be continually enlarged by expansion, particularly by inflation. The invention furthermore relates to the use of such bracing elements for a self-advancing shield tunnelling machine in which the control shield and the first bracing shield arranged behind it as well as the first and second bracing shield engage in each other and overlap telescopically.
