Abstract

PURPOSE:To permit the property discharge of a ground stabilizer by controlling the discharge pressure of a mixed fluid composed of a ground stabilizer and compressed air between the passive soil pressure and the active soil pressure at a depth of substrate where a stirring blade is located. CONSTITUTION:While injecting a mixed fluid composed of a stibilizer and compressed air from a discharge port 6, a rotary shaft 1 is turned by a rotary driver 2 to mix and stir the stabilizer and the ground. The discharge pressure P of the mixed fluid composed of the stabilizer and compressed air at the discharge port 6 is controlled so as to meet the formula Zo(rc-2alpha)<p<Zo(rc+2alpha) (where Zo is the depth of substrate, rc is the unit volume weight of clayey soil, is a proportional constant, Zo(rc-2alpha) is active soil pressure, and Zo(rc+2alpha) is passive soil pressure). The discharge pressure P can be controlled by controlling the discharge pressure of a stabilizer supplier 5 by means of a pressure control valve 8.
