摘要:
A method is characterized by clamping a pile above and below a break-off line with simultaneous undercutting of the pile along the break-off line.An apparatus for carrying out the method has an upper power frame (1) and a lower power frame (3) positioned one above the other and connected to each other by means of hydraulic breaking cylinders (2). The power frames (1, 3) are made up of blocks (6, 11) defining a closed figure and pivotally connected to one another by means of hydraulic clamping cylinders (7, 13). The axes of the hydraulic cylinders (7, 13) run perpendicularly with respect to the longitudinal axis of the pile.
