Abstract

PURPOSE:To conduct the leveling work, etc. of the pile head of a cast-in-place pile mechanically and rapidly by simultaneously applying pushing force to the inner wall surface and outer circumferential surface of a scraped pit formed to the pile head and crushing said pile head. CONSTITUTION:When crushing a pile head 2, an excavating head 13 is turned by means of a driving device 11 at first, and the excavating head 13 is dropped and inserted into the center of the pile head 2 by means of a vertically moved sliding device 9, and the pit 12 is formed. The rod of a jack 6 is extended, arms 3, 3' are mutually clamped to the inside, and pushing force is applied toward the inside from the outer circumferential surface of the pile head 2 through a chisel 7. A pushing head 15 in a vertical lever 10 is extruded in the external horizontal direction by means of a jack 14 at the same time, and pushing force is applied toward the outside from the inside of the wall of the pit 12. Accordingly, the pile head 2 is crushed uniformly extending over the whole circumference without damaging the internal reinforcing bars.
