ABSTRACT:
A ground anchor is provided comprising a first part engageable within an anchoring medium such as, for example, the ground, along an insertion axis; a second part to which loads are, in use, attached; and linking means interconnecting the first and second parts yet permitting displacement of the second part with respect to the insertion axis; so that when load is applied to the second part after the first part has been inserted within the anchoring medium the second part can alter position without moving the first part and thus reduce the effective loading on the first part. The second part preferably includes supplementary anchoring which penetrates the surface of the anchoring medium upon application of load to the anchor.
