PROBLEM TO BE SOLVED: To provide a simple slime processing device capable of uniformly and reliably floating slime deposited at the bottom of a pile hole over the entire circumference of the pile hole, and of sucking and discharging the slime. SOLUTION: In this slime processing device 1, a slurry in the pile hole H is supplied from a slurry supply pump 3 to an annular slurry injection pipe 2 through a slurry supply pipe 21, the slime deposited at the bottom of the pile hole H is floated by jetting the slurry from a plurality of injection nozzles 20 formed in the slurry injection pipe 2 toward the bottom of the pile hole H, and the slurry containing the floated slime is discharged to the outside of the pile hole through a slurry discharge pump 4. The intervals (angular intervalsα) of the injection nozzles 20 formed in the slurry injection pipe 2 are set smaller on the downstream side in the flow direction F of the slurry supplied to the slurry injection pipe 2 than on the upstream side.
