Abstract

PURPOSE: To enable the control of injection by correcting the flow rate of injection even when the fluctuation of the speed of intrusion of an excavator is large and even when the ground excavated requires the intrusion with an increased quantity of injection.
CONSTITUTION: When the excavator 1 is intruded, an optional quantity Vd of cement milk is injected irrespective of the speed of intrusion. The quantity of injection Vd is stored in a memory device 8 by depth. Next, at the time of drawing-up, a quantity Vu found after subtracting the quantity Vd injected at the time of intrusion from the target quantity of injection VT is injected. Accordingly, the instantaneous quantity of injection Qd at the time of intrusion is converted into the quantity of injection Vd by layers of the ground G by an operating and controlling device 9, while at the time of drawing-up the quantity of injection Vu is converted into the instantaneous quantity of injection Qu, and thus the quantity of injection is controlled to correspond with the change of the speed of drawing-up motion.
