摘要： PURPOSE:To permit the treatment of slime in a short time by a method in which a fluid is jetted in an unfolded fan-like way from the jet flow path to the center of the pile bottom side of a slime treatment apparatus, and slime is floated on mud water and sent with mud water to the ground's surface. CONSTITUTION:A water pump 20 and a mixer pump 22 are operated concurrently to jet mud water taken into a housing toward a foot protected part 13 through a jet flow path (a) by the pump 22 in an unfolded fan-like way. Slime 14 floated in mud water is taken into the housing through a sludge suction path(b), and the slime and the mud water are sent up to the ground's surface through a sludge discharge hose 17. The slime deposited on the pile bottom side can thus be treated in a short time.
