PROBLEM TO BE SOLVED: To treat sludge generated by a high-pressure jet mixing method at low cost. ;SOLUTION: In the high-pressure jet mixing method, grout is high-pressure injected into a ground 6 through an injected rod 1 while lowering or lifting the injection rod 1 into the ground 6 by rotation, and an improved body is prepared. Slurry discharged into a slime bit 53 through the periphery of the injection rod 1 during the execution of the high-pressure jet mixing method is forwarded to a raw water tank 66 through a vibration screen 67 first at that time, slurry in the raw water tank 66 is force-fed into a cyclone 70, gravel is separated from slurry, separated gravel is conveyed out to the outside of a system through a vibrating type dehydrator 73 from one end of the cyclone 70 and used as a construction material, a residual liquid separated in the cyclone 70 is sent to a slurry tank 62 having a built-in agitator 78 through a relay tank 63 from the other end of the cyclone 70, the concentration of a hardener for the residual liquid is adjusted, and the residual liquid is reused as grout.;COPYRIGHT: (C)1998,JPO
