TUNNEL CLEANING METHOD

A METHOD HAS BEEN DEVISED TO SCRUB TUNNEL SURFACES CLEAN BY USING ROTATING BRUSHES, WATER AND TUNNEL WASHING SOAP. PROPORTIONAL ELECTRO-HYDRAULIC CONTROL VALVES PROVIDE ACCURATE CONTROLS FOR THE OPERATOR TO POSITION BOOM MOUNTED BRUSH HEADS ON THE TUNNEL SURFACES. THE FOUR AXLE, 48,000 GVW CARRIER VEHICLE TRANSPORTS 1,000 GALLONS OF WATER, 700 GALLONS OF SOAP, OPERATOR AND DRIVER CABS, AS WELL AS ALL HYDRAULIC COMPONENTS NEEDED TO ACCOMPLISH THE TASK OF TUNNEL WASHING. TUNNEL OPERATING PERSONNEL ARE PLEASED WITH THE RESULTS AND STATE THAT THIS METHOD OF CLEANING IS THE BEST THEY HAVE TRIED. /DOT/
