Abstract
PURPOSE: To permit the exact injection of grout underground by controlling the pressure and amount of the grout being injected, the amount of cement supplied, and the amount of fresh water supplied by means of a preprogrammed controlling method.
CONSTITUTION: Values, e.g., the mixing ratios of water and cement on the basis of variations in the amount and pressure of grout being injected, etc., are put in a micro computer for controllers 15W17. In the first place, fresh water is supplied through a fresh water supply pipe 1 into a mixer 4 and also cement in a cement weighing tank 5 is supplied into the mixer 4 by a screw auger 6, where cement milk is prepared. The cement milk is injected underground by a pump 11, during which the pressure of injection is put in the controller 15 and signal is also sent to the controllers 16 and 17. The controller 16 serves to properly control the amount of cement to be supplied, and also the controller 17 controls properly the amount of fresh water to be supplied.
