  • Publication number: 20050115455
    Abstract: A guideway for a magnetic levitation train includes a levitating structure that is fixedly attached to a magnetic levitation train, and a guideway girder, which in an area that magnetically communicates with the magnetic levitation train is plate-shaped. The guideway girder has laterally protruding edges on which operational components are arranged, a portion of the guideway girder being embraced by the levitation structure in a U-shape. A sound-transmitting gap between end areas of the levitation structure and the guideway girder is formed as a labyrinth to reduce transmission of generated sound.

  • Patent number: 4662773
    Abstract: Segmental tunnel lining for tunnels, galleries and similar underground works, in which individual tubbings, made of reinforced concrete, are braced, in use, with each other both in annular or peripheral direction and in longitudinal direction with the aid of tension rods (3, 4) and corresponding tensioning elements (5). The rods connect neighboring tubbings (1) and extend in channels (2) in the tubbing. To obtain closed joints as planned in a simple and safe way, each tubbing has no less than one anchor element (6), which is firmly connected with the tubbing at least in the built-in state, for the purpose of anchoring the tension rod which effects the connection with the neighboring tubbing; and the tensioning element, which is arranged on the end of the tension rod opposite the anchor element, is freely accessible for the application of a tensioning machine in the direction of the shaft of the tension rod.

  • Patent number: 4499699
    Abstract: By means of a molding device for the fabrication of sub-soil curtain wall sections in the construction of the walls of sub-soil structures, measures are provided, even as the sub-soil curtain walls are being constructed, such that it is possible to introduce an injection of sealing compound into possible leakage points simply and optimumly after the building work has been completed. This arises according to the invention in that the molding device is a precast concrete structural part which remains in the sub-soil structure wall and which has at least one injection pipe which passes vertically therethrough and which is provided with injection valves for injecting leakage points with sealing compound.
