Abstract

PURPOSE: To perform the treatment for stabilizing soil so as to have a uniform strength, by a method wherein soil stabilizing agent, which hardens soil, is mixed in the middle of suction and discharge of soil.
CONSTITUTION: If the load of a pump 6 changes depending on an amount of soil and sand in water pumped up by means of a pump 4, a governor actuates to keep the pump 4 in a constant number of revolutions. Simultaneously, the change in the load is detected by a sensor, and a signal, proportioning an amount of soil and sand sucked, is sent to a control valve 11 from a controller. The control valve 11 automatically opens and closes to regulate the implanting amount of soil stabilizing agent in a slurry. The soil stabilizing agent, implanted into an implanting pipe 7, is mixed with soil and sand in a suction port 3, the pump 4, and a drainage pipe 6 for draining it into a section.
