Zusammenfassung:PURPOSE:To control caisson sinking easily even, in the ground having a high N value. CONSTITUTION:A plurality of cutting edges 5 divided, a sinking body 12 fixed through a plurality of these cutting edges 5 and a jack 31, and a vibrator 30 being disposed in a space 27 formed in the sinking body 12 in a projecting- retreating-able manner and vibrating the cutting edges 5 are provided. When a plurality of the cutting edges 5 are divided into several pairs of blocks and the cutting edge sections are excavated and the cutting edges are press-fitted successively at every block, the sinking body is sunk while vibrating the cutting edges.
