METHOD AND DEVICE FOR SNAPPING REINFORCED-CONCRETE PILES AND STRIPPING OF REINFORCEMENT

摘要

The method is characterized by clamping the pile above and below the snap line with its simultaneous under-cutting along said line. A device for implementation of the method comprises an upper (1) and a lower (2) power frame located one above the other and interconnected by snapping hydraulic cylinders (2). The power frames (1, 2) consist of shoes (6, 11) constituting a closed contour and hingedly interconnected to each other by means of clamping hydraulic cylinders (7, 13). The axes of the hydraulic cylinders (7, 13) are perpendicular to the longitudinal axis of the pile.
