摘要： PROBLEM TO BE SOLVED: To provide a method of creating an improved column body in the ground by injecting a hardening solution from injection nozzles of bracket-like agitation blades arranged on an injection rod, wherein the improved body has uniform strength at the center of the rod, and wherein penetration resistance of the agitation blade is eased.
SOLUTION: The injection rod 1 having an excavation bit at the tip thereof has the bracket-like main agitation blade 6 and auxiliary agitation blade 7 arranged at lower portions thereof in two stages, and a radius of the auxiliary agitation blade 7 is formed so as to be 1/2 to 1/4 that of the main agitation blade 6. When a boring water quantity necessary for penetration is set to 0.1 to 0.3 times the boring water quantity is ejected from the auxiliary agitation blade nozzles, and the injection rod is rotatively lowered, to thereby facilitate penetration of the rod into intermediate and bottom layers. When the hardening liquid is injected, the diameter of each nozzle is adjusted such that 0.7 to 0.9 times the boring water quantity is ejected from the nozzles of the main agitating blade 6, and that 0.1 to 0.3 times the boring water quantity is ejected from the nozzles 9 of the auxiliary agitation blade 7. Then the injection rod 1 is rotatively raised or lowered during execution of earth discharging, or without execution of earth discharging while the hardening solution is ejected from the nozzles at high pressure. In this manner, the uniform improved rod body is created in the ground.

摘要： PROBLEM TO BE SOLVED: To provide a soil improvement construction method using a soil improving machine mounted on a marine vessel, by which method an improved land having a uniform quality and a planned form is constructed by simple operation even if a water level changes.
SOLUTION: A mixing stirring apparatus 3 is used as a soil improving machine. The mixing stirring apparatus 3 includes a stirring blade 4 which stirs a soil 6 and has a nozzle for jetting a solidification agent slurry, and a stirring shaft 5 for vertically moving up and down the stirring blade 4. As the stirring shaft 5 is repeatedly moved up and stopped alternately between the lower end and the upper end of a soil improvement area A, the solidification agent slurry is jetted continuously from the stirring blade 4 at a specific jet flow rate and jet pressure. The distance of upward movement of the stirring shaft 5 of the stirring apparatus 3 is adjusted to a change in a water level for each time interval that is arbitrarily determined under an assumption that the rate of change in the water level in the determined time interval is constant so that a jet rate of the solidification agent slurry in a unit length in the vertical direction in the soil improvement area A becomes constant.
