ABSTRACT:
The present invention generally relates to a new and improved method by which colloids, clay, silt, and silt-mixed sand (hereinafter referred to as "weak soil layer") which exist in rivers, lakes, marshes, harbours, and the sea, can be easily and immediately turned into stabilized foundation ground necessary for civil construction, and particularly relates to a new and improved treatment equipment which is effective to continuously treat said weak soil layer over a height from a bottom supporting foundation, by discharging a solidifier agent of special cement which is continuously agitated by agitator impellers.
