PURPOSE: To clean the inside of a drain pipeline in a short time with a small amt. of cleaning soln. by inserting a foreced-feed hose into the pipeline, injecting a cleaning soln. with the temp. and pressure adjusted to release the contaminant depositing on the inner wall face and then injecting clear water. CONSTITUTION: The nozzle 3 of a pressurized cleaning soln. feeder 20 is inserted into the outlet 2 of a drain pipeline 1, and the cleaning soln. controlled to 4-5kg/cm<2> and 40 deg.C in a compression part 4 is injected from the nozzle 3 through a foot valve 6 communicating with a forced-feed hose 5. Consequently, the deposit 7 in the pipeline is released, and the nozzle 3 intrudes deep into the pipeline 1 by itself. Further, the released deposit 7 is collected in a contaminant container 15 through the pipeline 14 of a drain inlet 16 of the pipeline 1. Clear water is then injected into the pipeline 1 to remove the residue in the pipeline 1. |
