摘要： PROBLEM TO BE SOLVED: To provide a jet agitating device using cross jet streams capable of preventing direct application of resistance of ground soil to a jet stream discharge part to simplify the device structure, efficiently injecting high pressure jet, and dispensing with preceding excavation to smoothly perform soil improving work.
SOLUTION: A monitor part 10A is constituted by being provided with an excavating blade 12 provided at the lowest end part of an insert pipe 11, an agitating blade 13 provided above the excavation blade 12 on the inert pipe 11, and an upper and a lower jet stream discharge parts 14 and 15 provided at a prescribed interval in a vertical direction of the insert pipe 11. The agitating blade 13 is composed of an upper and a lower agitating blades 13A and 13B vertically forming a pair to respectively correspond to the upper and lower jet stream discharge parts 14 and 15. The upper and the lower jet stream discharge parts 14 and 15 can thus be respectively covered with the upper and the lower agitating blades 13A and 13B ahead of them in their moving direction, thereby direct application of ground soil resistance is prevented from acting to the upper and the lower jet stream discharge parts 14 and 15 when the insert pipe 11 is rotated.

摘要： PROBLEM TO BE SOLVED: To provide a high pressure injection nozzle tube capable of increasing the piling speed of especially small diametral solidification piles and a solidification piling device provided with the tube.
SOLUTION: The high pressure injection nozzle has at least the inner diametral face 11 tapered off to the front end on the inner peripheral face and has a nozzle part 1 having a male screw section 14 at the outer peripheral face and a female screw part 31 screwing with the male screw section 14 of the nozzle part 1 at the inner peripheral face of the one side. The high pressure injection nozzle tube is provided with a tubular base part 3 connected to a high pressure liquid feeding means at the other end side, a tapered off needle part 21 located in the neighborhood of the front end of the nozzle 1 at the front end side, and a nozzle aperture adjustable member 2 fixed to the tubular base part 3 so that the axial center coincides with the axial center of the tubular base center 3. The solidification piling device using the same is provided.
