Abstract
Agitation shafts provided with agitation vanes at lower portions thereof are fixed rotatably around a support cylinder to form a soft ground hardening machine. A direction control unit is provided at a lower portion of the support cylinder so as to control the direction in which the machine is inserted into and withdrawn from the soft ground. In a method of hardening the soft ground by using this machine, the direction in which the machine is inserted into and withdrawn from the soft ground is controlled as the direction in which the machine is being inserted into or withdrawn from the soft ground is measured.
