PROBLEM TO BE SOLVED: To provide a production device of a solution type grout capable of obtaining grouts having a predetermined grain size or lower with a simple structure, different from a complicated and large device such as a classification tank using gravity, or a device using a filter material which needs function regeneration periodically by replacement of the filter material or back washing or the like.SOLUTION: The production device comprises: centrifugal force application means having an agitator 2 for applying centrifugal force to a raw material of a solution type grout formed of mainly colloidal silica; and extraction means having a discharge pipe 4 for extracting the solution type grout to be poured into a foundation from a center of the raw material on which the centrifugal force acts. |
