Abstract (en)
[origin: WO2011116483A2] The device for an at least partially removable anchor comprises at least one tension member (9) that can be pre-loaded and an induction coil (16) surrounding the tension member for disconnecting the tension member at a disconnection point (12) by inductive heating. The induction coil (16) is arranged on a carrier pipe (15), which is sealed (17, 20) on the side of the disconnection point (12) facing the part (7) of the tension member that can be pre-loaded. The area between the induction coil (16) and the disconnection point (12) is free from an electrically conducting metal pipe. In order to at least partially remove the anchor, the tension member (9) is pre-loaded during the heating process with a force that corresponds to at least 10%, preferably at least 25%, and especially preferably at least 50% of the fracture force of the tension member at 0 degrees Celsius.
