摘要： PURPOSE: To enable expansion digging at the time of bulb development without depending on a hollow pile by fitting a rotating cylinder with play to the peripheral part of an excavating rod, and providing the rotating cylinder with a pressure receiving plate and engaging grooves for controlling the attitude of expansion blades. CONSTITUTION: Expansion blades 5, 5 are positioned in the positions of the second engaging grooves 162 , 162 of a rotating cylinder 12 and put in the contracted state. In this state, an excavating rod 2 is rotated normally to excavate the ground. At the time of reaching the specified depth and expansion-digging the lower end of an excavated hole, the rod 2 is rotated reversely. The pressure receiving plates 15, 15 of the rotating cylinder 12 thereby receive the resistance of sediment so as to be rotated relatively to a head 2, and the blades 5, 5 enter into first engaging holes 161 , 161 and rotate upward so as to be put in the enlarged state of enabling expansion digging. When the rod 2 is rotated reversely, the rotating cylinder 12 is further rotated, and the inclined face 17 is rotated along the blade 5. The blades 5, 5 are thereby pressed downward, and a third engaging groove 163 is engaged with the blade 5, so that the blade 5 is returned into the contracted state, and the rod 2 is pulled out of the excavated hole.
