Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a solid-liquid separation method in the classification of earth and sand capable of easily separating a sand material from earth and sand containing moisture or the like after classification to effectively utilize the same as a building material and capable of reducing the amount of dredged earth and sand disposed for landfilling, and an apparatus using the same. SOLUTION: Water and, silt and clay contained in water are sucked and discharged by a pump 4 with a float 3 while storing sand, water, and silt and clay contained in water discharged after classification in a hopper and sand S in the hopper 2 is discharged by opening the valve 7 disposed at the lower end of the hopper.
