Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an existing pipe crushing device which is structured to prevent an increase in the number of working processes and working hours, and increase in the labor burden when a plurality of existing pipes like chimneys are crushed. SOLUTION: The existing pipe crushing device is intended for the plurality of the existing pipes whose ends in the extending direction are arranged together in the same place. A cutting tool capable of moving in the extending direction of the existing pipes and in the plane orthogonal to the extending direction is provided. The cutting tool is structured so that it can abrasively cut off the plurality of the existing pipes by moving in the plane orthogonal to the extending direction of the existing pipes at the position after moving in the extending direction.
