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 problem that conventionally a retaining wall is constructed around polluted soil to excavate and remove the polluted soil when land polluted in the past is cleaned and restored and thereafter, the excavated space is filled with a cleaning material or sand but large-scaled cut-and-cover construction is required for the purpose of excavation and removal and, when pollutant is deeply present in the ground or at a place where the retaining wall is difficult to construct because of an obstacle or the like, polluted soil is difficult to recover.
SOLUTION: A suction hole 5 is provided to a region separated from a high pressure jet nozzle 3 by a predetermined interval and a suction rod allowing the suction hole to communicate with a discharge route equipped with a suction mechanism is inserted in the polluted soil layer of the target ground. Fresh water is ejected under high pressure from the jet nozzle while rotating the rod not only to crush polluted soil but also to bring the polluted soil to a muddy state. Muddy water is sucked from the suction hole by utilizing the pressure generated in the ground by high pressure ejection and discharged to a recovery tank through the discharge route in the rod to be recovered in the tank.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus and a construction method allowing the simultaneous soil improvement of a joint part to an earth retaining wall and parts other than the joint part.
SOLUTION: A hardening material discharged from an ultra-high pressure pump 30 is led into a rod via a passage changeover part 20. The passage changeover part 20 changes between a passage A for leading the hardening material into the rod, and a passage B for returning the hardening material into a hardening material tank 50. When the rods 1a, 1b, 1c are rotated by a motor 60, stirring blades 2a, 2b and 2c are rotated, and nozzles 3a, 3b and 3c are also rotated. During the rotation, the hardening material is constantly jetted from the low pressure nozzles 3a, 3b and 3c, while the hardening material can pass through the passage A only when the rod 1a is in a prescribed rotation angle range by the passage changeover part 20. The hardening material is thus jetted by ultra-high pressure via the passage A only when the ultra-high pressure nozzle 4 faces a steel sheet pile or the earth retaining wall such as a continuous underground wall.
