    Abstract: PROBLEM TO BE SOLVED: To provide improved technology for forming a cylindrical improved area outside a rotational area of stirring vanes with high pressure injection.
    SOLUTION: A high pressure fluid for improving a ground is injected from nozzles provided at the ends of the two stirring vanes 2, 2 on the same plane (or a plurality of nozzles provided at the end of one stirring vane or a plurality of nozzles located on the rear side of one stirring vane in the rotating direction) in an almost horizontal direction while crossing each other at a point P outside the rotational area A of the stirring vanes 2. The improved area B can be formed with the upper and lower ends in a horizonal condition, without the control of the injecting angles of the nozzles, as required so far.

    Abstract: PROBLEM TO BE SOLVED: To greatly reduce the facility costs by improving overall earthwork efficiency by rationally performing the transport, treatment and earth filling and, at the same time, without being restricted by the area for installing the equipment. SOLUTION: Sediment (a) from dredge or the like is transported by a barge 1, and this transported sediment (a) and a solidifier (b) are mixed together and treated earth (c) is produced and the treated earth (c) is moved to an earth filling area X and then filled. In this case, there are several steps including a process for transporting sediment (a) from dredge or the like to a predetermined place (w) rear the earth filling area X by a barge 1, a mixing process for making treated earth (c) by mixing a solidifier (b) to the transported sediment (a) by using a mixing means 12 from the external of the barge 1 and a filling process for placing treated earth (c) from the barge 1 to sea floor or the bottom of the water at a place x1 for discharging the treated earth.

    Abstract: 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.

    Abstract: PROBLEM TO BE SOLVED: To decrease the volume of the disposal of soil by effectively using soil coming out from the offshore ground improvement work.
    SOLUTION: The soil 1 coming out from the offshore ground improvement work is mixed with an improved material and a coarse-grain material to obtain a mixed soil containing water content of 25% or less, plasticity index of 20 or less and fine-grain content of 15% or more, and a use for the soil coming out from the offshore ground improvement work using the mixed soil as a filling material for forming a compaction sand pile.
