Abstract (en)
Pile forming apparatus 10 includes an auger 12 and hollow member 14. The hollow member 14 is open-ended at 16. An external projection 18 forms a helical flight. In use, the auger 12 is positioned within the hollow member 14, to extend through the mouth 16 of the hollow member 14. The auger 12 and the hollow member 14 are each rotatable and are rotatable relative to each other. In use, the auger 12 draws spoil into the hollow member 14 and the hollow member 14 advances into the ground by engagement of the helical flight 18 with the surrounding ground. The speed and relative speed of the auger 12 and the hollow member 14 controls the degree of compaction created within the ground around the apparatus 10.
