摘要： PROBLEM TO BE SOLVED: To provide a cleaning vehicle capable of cleaning the whole wall surface of a tunnel while traveling in the same direction as general vehicles without interfering with the following vehicle in cleaning the wall surface right beside the vehicle, and easily performing cleaning work by one vehicle without becoming large-scaled dispensing with an exclusive rotary brush for cleaning a guardrail.
SOLUTION: This cleaning vehicle 1 has bendable arms 12, 13 on a body frame 5 of the vehicle, a brush 6 at the tip of the arms 12, 13, and an operating chamber 4 for operating the arms 12, 13. The side edge of the body frame 5 is provided with a cutout 26 for receiving at least a part of the brush 6. The brush can thereby be enclosed in the cutout to clean the tunnel wall surface right beside the vehicle, so that a brush space between the wall surface and the vehicle can be reduced. The vehicle can thereby clean as it is close to the wall surface during low speed travel cleaning, which does not interfere much with the travel of the following general vehicle.

摘要： PROBLEM TO BE SOLVED: To increase the efficiency of cleaning works, by delivering water in a water tank mounted on a vehicle at a high pressure and jetting the high pressure water on a road face through a nozzle to collect rubbish on the road face to a certain direction and gathering it into a hopper mounted on the vehicle. SOLUTION: Water in a water tank 20 mounted on a vehicle is highly pressurized by a high pressure water generator and jetted onto a road surface through a nozzle 11. In this state, the vehicle is moved forward at a specified low speed to clean the road face and push the rubbish to one end side of the road by the jet pressure of high pressure water. The rubbish gathered to one side of the road is sucked into a base machine from a suction box 2 and contained in a collecting chamber 4 of the hopper 1 through a suction hose 3.
