Zusammenfassung:PURPOSE:To prevent the separation of a slurry by a method in which while a slurry flows out of a placing tube, the valve mechanism of the placing tube is controlled so that the amount of slurry to be supplied to the placing tube is equalized with the amount of the slurry to be flowed out of the placing tube. CONSTITUTION:While concrete 12 is supplied into the tube 14 of a placer 10, the concrete 12 in the tube 14 is allowed to flow out by opening the outlet of a valve mechanism 18. The opening degree of the valve 26 of the mechanism 18 is controlled, while the concrete 12 is placed, by a controller 22 for the mechanism 18 in such a way that the amount of concrete 12 to be discharged from the tube 14 is equalized with the amount of the concrete 12 to be supplied to the tube 14. The tube 14 can thus be kept filled with the concrete 12 to prevent the outflow of the concrete 12 with high speed under its own weight. The separation of the concrete 12 can therefore be avoided.
