Patent

CA 2087537

A method and apparatus are described for preparing an end of a reinforced concrete pile (68). Excessive lengths of the driven pile are cut off using a shear blade (22) that is driven through the concrete and reinforcing steel (102) of the pile. Concrete is then removed down to a certain level below the cutoff position using a pair of blades (62) that engage the surface of the pile and penetrate the surface while wedging the upper part of the pile up away from the main body of the pile. This cracks the con- crete through at the desired position. At the same time, concrete breakers (88) engage the concrete pile above the blades to frac- ture the concrete from the reinforcing steel. This eliminates the need for cutting of the piles with explosives and the removal of concrete using pneumatic hammers.
