Improvements in screw piles
Abstract A screw pile end piece (10) comprises a body portion (12) having a first frusto-conical inwardly tapered portion (18) and a second tapered portion (20) tapering towards a tip (22) and a helical screw (30) in the form of a fin, the end piece (10) defining a central axis passing from one end of the body portion to the tip, wherein the angle of taper of the second tapered portion relative to the central axis is greater than the angle of taper of the first tapered portion. It is preferred that the maximum diameter of the body portion is less than half the maximum diameter of the fins of the end piece. ,33 I(0 H-A
