ABSTRACT:
In order to make a tension member (1) substantially removable from the ground or from a structure, a central element (2) thereof is completely severed. If the tension member is to be further weakened, at least one outer element (3) is also severed besides the central element. A supporting contrivance (5) is applied to the tension member either around the point of separation (4) of the central element or around both points of separation (4, 6) of the central element and of the outer element. By application of a load, the tension member is torn apart near the point or points of separation so that the major part of the tension member can be pulled out of the ground or structure and, if need be, reused.
