SLUDGE DISPLACING EQUIPMENT, SLUDGE DISPLACING SYSTEM, AND SLUDGE DISPLACING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide sludge displacing equipment which enables the removal of sludge and the embedment of a modified material to be performed through a series of flows, a sludge displacing system, and a sludge displacing method. PSOLUTION: The sludge displacing equipment 1 makes sludge displacing work performed as follows: a backhoe 13 makes the equipment 1 installed on a sludge layer 17 in a work place in a state that an inner casing 3 is in a sludge suction position; after that, the sludge is removed by pressing the equipment 1 into the sludge layer 17 conforming to the height of the sludge to be removed by the use of the backhoe 13, while agitating the sludge and sucking the agitated sludge; subsequently, the inner casing 3 is lifted by the backhoe 13 so that a space from which the sludge is removed can be formed in an outer casing 2; thereafter, the modified material 19 is charged from a modified material charging part 4; and the backhoe 13 makes the equipment 1 lifted from inside the sludge layer 17 after the modified material 19 is embedded in the space from which the sludge is removed.
