发明名称 Arrangement for severing the tension member of a soil anchor at a predetermined location by induction heating
摘要 An arrangement for severing a tension member of a permanent soil anchor of ferromagnetic material at a predetermined location includes a coil surrounding the tension member in a tubular manner at the predetermined location, wherein the coil is mountable together with the tension mender. A high temperature-resistant thermal insulation layer is provided underneath the coil and a tubular core is arranged between the high temperature-resistant layer and the tension member, so that the coil forms a primary winding and the core forms a first secondary winding and the tension member forms a second secondary winding. The tension member is severed by applying an electric current having a frequency of approximately 5 to 30 kHz and a voltage of approximately 500 to 800 V to the coil, so that the tensile strength of the tension member is reduced at the predetermined breaking point by the heat produced by induction resulting from the electric current.
