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.

摘要： PROBLEM TO BE SOLVED: To provide an expandable head which eases excessive excavation resistance generated at the time of expanding expandable blades, positively carries out contraction of the expandable blades, and is solid and inexpensive.
SOLUTION: The expandable head does not use a hydraulic cylinder or a link mechanism for expanding the expandable blades, and it is essentially set such that the expandable blades are locked in a contractive state beforehand during ordinary excavation, but that the expandable blades are expanded by using external force after cancellation of locking during expanded excavation. A head rod of the expandable head is formed of an upper driving shaft having the expandable blades axially mounted on an external periphery in a longitudinally expandable and swayable manner, and a lower driven shaft having an excavation head protruded from an external peripheral surface, and the shafts are fitted to each other in a manner rotatable and axially slidable with respect to each other. Herein the head rod thus formed has key grooves each with an auxiliary key groove bored in an area between the upper driving shaft and the lower driven shaft, and keys engageable with the respective key grooves.

摘要： PROBLEM TO BE SOLVED: To provide a method of forming a soil cement composite pile capable of preventing earth and sand from rotating together with an agitating blade and sufficiently agitating and kneading cement milk and excavated earth and sand.
SOLUTION: The method of forming the soil cement composite pile is as follows. Namely, using a hollow pile inner excavation device, an excavating rod is rotated in a normal direction while agitating blades on a normal rotation side are extended, and the hollow pile is rotated in the reverse direction interlocking reverse rotation side agitating blades. While a vertical hole is excavated by the excavating rod rotated in the normal direction, the hollow pile rotated in the reverse direction is sunk in the vertical hole. In this process, while a cement hardening liquid is injected into the excavated hole, the hardening liquid and the excavated earth and sand are agitated and kneaded in a plurality of areas of opposite directional rotation and agitation between the vertically adjacent normal rotation side agitating blades and the reverse rotation side agitating blades to form the soil cement. The hollow pile is positioned in the soil cement. When the hollow pile is positioned to an intended depth, the agitating blades on the normal rotation side and the reverse rotation side are closed and contracted, and the excavating rod is pulled out of the hollow pile.
