SELF-BORING ANCHORING DEVICE AND METHOD OF INSTALLING SUCH AN ANCHORING DEVICE
A fixation device is described comprising a shaft rotatable about a longitudinal axis with a first cutter at a first, distal end; a guide body on the shaft shaped to taper outwardly towards the first end of the shaft; an elongate sleeve disposed surroundingly about the shaft to be rotatable separately from the shaft and translatable in a longitudinal direction relative to the shaft; a flareable end formation at a first, distal end of the elongate sleeve comprising one or more second cutters; the guide body and flareable end formation being arranged so that urging the sleeve towards the first end over the guide body flares the end formation outward from the shaft; and a tensioning mechanism associated with a second end of the sleeve operable selectively to urge the shaft relative to the sleeve back towards the second end. A method of installing a fixation device into a substrate is also described, for example to serve as an anchor and pile, for example for a submerged or floating object.
