摘要： PROBLEM TO BE SOLVED: To solve the following problem that, conventionally when a hardener is diagonally or horizontally injected, a pump of standard performance cannot exert sufficient injection pressure and a discharge amount, resulting in insufficient injection, and in order to enhance the injection pressure and the discharge amount during the injection of the hardener into the target ground, a special high-performance pump at a cost equal to three times or more the cost of a standard pump is required.
SOLUTION: There is provided a multi-injection nozzle 3 composed of a core nozzle and circumferential nozzles enclosing the same, and the nozzles are connected to injection material feeding channels 2a, 2b, etc. , respectively, which then have respective high-pressure pumps arranged therein. Upon the simultaneous pressurization of the pumps, the injection materials are injected in a multi-overlapping manner, and therefore injection pressure of each injection material becomes synergistic, to thereby enhance the injection energy of high-pressure jet of the injection material in the target ground.

摘要： PROBLEM TO BE SOLVED: To solve the following problems: in hardening layer formation using direct agitation by an agitation blade, fluid agitation by a jet flow of a hardening material, and hardening material injection together, horizontal injection is mainly used conventionally as the hardening material injection, so that a hardening material is not sufficiently spread into an agitation area, which causes a high rotating torque and easily generates uneven mixing of soil with the hardening material, whereby uniform agitation and mixing of the soil cannot be carried out.
SOLUTION: Upper agitation blades 11A, 11B are respectively provided with downward injection nozzles 22a, 22b. Lower agitation blades 12A, 12B which intersect with the upper agitation blades crosswise are provided below the upper agitation blades, and a part above the mounting base of one of the blades and a part below the mounting base of the other of the blades are respectively set with horizontal injection nozzles 31a, 31b to perform agitating injection while rotating a rod.

摘要： PROBLEM TO BE SOLVED: To solve the following problems: a driving head for agitating and mixing soil by the go-around drive of a drive chain by laying the drive chain in a tensioned state on a driving wheel is inefficient because an agitation and mixing range is limited on ground that a working surface of the driving head is conventionally narrow due to the go-around of the narrow chain; and a portion, to which an agitating operation is not applied, is produced because a process range is set on a piecemeal basis.
SOLUTION: A crawler 12 is triangularly laid in a tensioned state by arranging two driven wheels in the lower portion of the driving wheel 11a; an agitation working body 1 is constituted by juxtaposing a plurality of agitating blades 13, directed obliquely with respect to an outer peripheral surface of the crawler, on the outer peripheral surface thereof; and a bottom portion of the working body with a large working surface serves as a digging end portion by a main shaft leader 2 which has the working bodies rotatably mounted on both the sides of a leading end.
