APPARATUS OF PRODUCING MIXTURE OF SOIL AND WATER USING HIGH PRESSURE WATER

PROBLEM TO BE SOLVED: To provide a compact mixing apparatus capable of mixing a soil composed of a mainly granular solid and water evenly within a short time. SOLUTION: The apparatus is a production apparatus of a mixture of soil and water and includes an inlet can having a nozzle for jetting pressurized water having 2 to 20 MPa and a throwing inlet for soil, a tube having a first end and a second end, and a scattering prevention can having a baffle plate, a discharge outlet, and a gas discharge port. The nozzle is so installed as to jet pressurized water as a high speed jetted fluid from a side face of the throwing direction of the soil and satisfies the conditions; that is, the first end of the tube is connected to the inlet can along the jetting direction of the tube, the second end of the tube is connected to the scattering prevention can, the inner diameter (Dn) of the discharge outlet of the nozzle is 1 to 20 mm, and the inner diameter (Dp) of the tube is 5 to 50 times as large as the inner diameter (Dn) of the discharge outlet of the nozzle. Consequently, the apparatus is for producing a mixture of soil and water by mixing soil thrown to the throwing inlet with water derived from the pressurized water during the time the soil reaches the second end.
