| 20120121338 | SEALING ARRANGEMENT FOR SHAFT AND TUNNEL CONSTRUCTION - A sealing arrangement for shaft and tunnel construction. The elastic tension forces that arise when the sealing systems are pressed against each other by reducing the joint clearance, after the systems have been brought into contact with each other, are reduced or completely avoided relative to prior art, and the required surface contact pressure is achieved by means of a self-sealing force effect of the media pressure. In order to achieve the force effect, the geometry of the sealing elements of the sealing system is designed such that the elements comprise pressure surfaces relative to a vacuum or atmosphere after contacting each other. A differential pressure acts on the pressure surfaces, resulting in the force ensuring the required surface contact pressure on the surface, by means of which the sealing elements contact one another at the contact plane. | 05-17-2012 |
