Abstract
The tension part (1), which can be extracted from the earth after use, comprises a central member (2) and a plurality of outer members (3). At least one (3') of the outer members is completely servered. Pressed on radially about the tension part is a tubular supporting element (5). The point of severance (4) is situated in the entry region of the supporting element. Disposed between the supporting element and the tension part is an insert (11) having inner teeth (13) for a secure grip. Through the severance of one of the outer members, substantially greater ductility is achieved before breakage takes place. This in turn allows better monitoring of soil anchors produced with such tension parts.
