摘要:
The slurry is prepared by a mixer (12) (30) and the mixed slurry is then agitated by an agitator (36). Before underwater placement of the slurry, bubbles in the slurry is reduced. The apparatus includes a supplying device for supplying a hydraulic material and water in a predetermined ratio; a mixing device (12) (30) for mixing the hydraulic material and the water supplied from the supplying device to produce a slurry; an agitating device (36) for receiving the slurry from the mixing device (12) (30) and for agitating the the slurry; and a deaerating device (38) for receiving the agitated slurry from the agitating device (36) and for deaerating the agitated slurry.
