摘要： PROBLEM TO BE SOLVED: To prevent the reduction in stirring efficiency even when reducing a torque in a ground improving body creating device.
SOLUTION: A passage for high-pressure fluid is formed in an injection rod 11, and a high-pressure fluid is injected from injection nozzles 20 and 22 in ground improvement. Stirring blades 12 extending radially outward to the axis of the injection rod are provided on the circumference of the injection rod, and the stirring blades are rotated according to the rotation of the injection rod. The injection nozzles are arranged on the tip parts of the stirring nozzles and comprise nozzle ports opened toward the injection rod. In the area separated from the injection rod, considering that the ground is stirred by high-pressure jet, and the torque is proportional to the distance from the central part when the stirring blades are rotated, the torque acting on the vicinity of the tip parts of the stirring blades can be minimized.

摘要： PROBLEM TO BE SOLVED: To provide an excavation head of an excavator for constructing a foundation pile, superior in excavation performance, capable of securing the quality of a foot protection expanded bulb, and capable of suppressing an earth removal quantity when pulling up, in the excavator in the form of gradually diametrically expanding an expanding blade by a spline structure.
SOLUTION: This excavation head 1 has a hollow driving shaft 2 and an excavation shaft 3 relatively movably stored in the axial direction inside its shaft. The expanding blade 4 joined by a pin to the driving shaft 2 side is expanded and contracted via a diametrically expanding plate 5 on the excavation shaft 3 side by using these relative movements. A spline is formed of a U-shaped key way 6 on the inner surface side of the driving shaft 2 and a key 7 on the outside surface side of the excavation shaft 3. The key way 6 is formed in a U shape out of a guide part 6a in the vertical direction, a first locking lock part 6b in which the key 7 is engaged in the circumferential direction when normally rotating the driving shaft 2 in the diametrically contracted state of the expanding blade 4, and a second locking lock part 6c in which the key 7 is engaged in the peripheral direction when normally rotating the driving shaft the a diametrically expanding state of the expanding blade 4.
