ERASING METHOD AND ERASING DEVICE FOR ROAD COMPARTMENT LINE

PROBLEM TO BE SOLVED: To provide an erasing device excellent in work efficiency and to easily erase a compartment line by injecting dry ice particles with high pressure air, cooling the road compartment line to weaken the binding force of a compartment line and the road surface, and separating the compartment line from the road surface by high pressure air injecting force. SOLUTION: Dry ice particles are adjusted to have a diameter about 3 mm and stored in a hopper 4, and then introduced into an injection gun 5 through an injecting device 3. In this case, high pressure air and dry ice particles are separatedly put in the injection gun 5, and mixed in a nozzle to be injected. After dry ice particles are injected to a road compartment line to be erased, the dry ice particles are subliminated so that only the separated road compartment line is easily recovered. An erasing device comprises a compressor 1, an oil filter, a drier 2, a dry ice particle injecting device, and an injection gun 5, and the device is transferred by an automobile. Thus in a cite for erasing the road compartment line, the erasing device can be simply operated.
