In order to simply and easily treat drainage produced by cutting a face to be cut such as concrete without discharging the drainage on a road, a floor of a building, or the like, the concrete cutting machine of the present invention comprises a cutting mechanism for cutting the face by means of a rotating blade covered by a cover, a water supply mechanism for supplying and jetting water cooling to the rotating blade, and a collecting mechanism for collecting the drainage produced inside the cover by the jetting of the water cooling when the face is cut by the rotating blade. Further, in the collecting mechanism, the drainage produced inside the cover is sucked through a sucking portion provided on the lower end periphery of the cover to a collecting portion by a sucking operation of a suction blower so that the drainage in which air is removed at the collecting portion is discharged by a pump for collection.
