摘要：PURPOSE:To permit the construction of vertically and continuously improved ground by preventing the bending of a soft ground improver due to imbalance in the reaction force of excavation by providing an expander by which the vertical attitude of driving member can be maintained. CONSTITUTION:Where soft ground is continuously improved, when an inclination of a strut 22 is detected by an inclinometer 33 provided to the strut 22, the inclination of the driving member is corrected so as to keep it attitude vertical by expanding or shrinking the rod of a fluid-pressure cylinder 29 in such a way as to work the reaction force of excavation in the opposite direction and turning the driving member 24 including an excavating blade 27, a stirring blade 26, and a stirring shaft 25 in such a manner that the inclinometer 32 provided to the upside of the driving member 24 shows an inclination of the same magnitude as the detected inclination of the inclinometer 33 on its opposite side.
