PURPOSE: An apparatus for washing a cleaning equipment for tunnel and sound-absorption wall is provided to clean various forms and sizes of portions to be washed in any tunnel or sound-proof walls by constructing the apparatus with a variety of shapes of bending bars. CONSTITUTION: The apparatus comprises multiple fixed bending bars(52) to be selectively used; brushing rotators(40) having different lengths capable of being selected along heights; a connector inserted between the brushing rotators; a driving gear(41) to rotate the connector by the rotation of a hydraulic motor; an access alarm sensor at upper end of the roller cover(14) for preventing impact to the washed side. The bending bar(52) has a rectangular pipe, a drum provided with five springs at both ends of the pipe and a fixing portion to stop vibration caused by the rotation of the brushing rotator(40).
