Abstract
PURPOSE: To reduce the required working time through crushing of the concrete section of the pile by pounding it with a inverted-cone-shaped wedge inserted into the upper open end of the pile in a crusher of the upper excess part of the concrete pile already driven.
CONSTITUTION: A guide 4, the lower portion of a short rod and the lower portion of an inverted-cone-shaped wedge 14 are inserted into the upper open end of the excess part 3' projected above the ground of the concrete pile 3 driven while the pile 3 and the wedge 14 are retained concentrically with the wedge surface 2 (the angular part 2" of a hexagonal cone) supported on head inner periphery of the pile 3. Subsequently, a pounding section of an air hammer rock drill 16 suspended with a wire 1 of a crane is inserted into the upper end of the short rod 1 and the wedge 14 goes down below the center line of the pile 3 by pounding or pressing the pressure receiving surface 5. Thus, the wedge 14 is allowed to press-crush the concrete part 3" of the pile 3 toward the outside from the inside thereof.
