Abstract
A piling structure or ground anchor comprising at least one piling member portion adapted to be driven into the ground or inserted into a pre-bored hole therein (31); a spreading mandrel member (34,40) adapted to be passed into the structure or ground anchor so as to expand the piling member (31) portion laterally into the ground; and holding means (45) for holding the piling member portion in its expanded disposition.
Claims24
A piling structure or ground anchor comprising a deformable piling member portion adapted to be driven into the ground or inserted into a pre-bored hole therein;
- a spreading mandrel member adapted to be passed into the structure or ground anchor, the arrangement of the piling member portion and the mandrel being such that by passage of the mandrel the piling member portion is deformed into local lateral movement to expand the structure or ground anchor progressively therealong, laterally into the ground;
- and holding means for holding the structure or ground anchor in its expanded disposition.
A structure or anchor as claimed claim wherein the piling member portion comprises:
- a succession of rings inserted one on top of the other in the ground, the rings being provided with a plurality of axially aligned weak lines spaced therearound whereby passage of the mandrel member into the structure opens out the rings along the weak lines to expand the structure or ground anchor.
A method of forming a piling structure or ground anchor comprising inserting a deformable piling member portion longitudinally into the ground;
- progressively deforming the piling member portion along its length by local lateral movement thereof into the ground to expand the structure or ground anchor progressively therealong laterally into the ground;
- and holding the structure of ground anchor in its expanded disposition.
A piling structure comprises:
- at least two piling member portions adapted to be longitudinally driven into the ground or inserted into a pre-bored hole therein in generally parallel alignment;
- mandrel means adapted to be passed longitudinally between the piling member portions for progressively spreading apart the piling member portions laterally while the piling member portions remain in generally parallel alignment;
- and
- holding means for holding the piling member portions in their spread apart disposition of generally parallel alignment.
A method of forming a piling structure comprises the steps of:
- inserting longitudinally into the ground at least two piling member portions in generally parallel alignment;
- passing a spreading mandrel member longitudinally between the piling member portions to progressively spread apart the piling member portions laterally while the piling member portions remain in generally parallel alignment;
- and
- holding the piling member portions in their spread apart disposition of generally parallel alignment.
