摘要

PROBLEM TO BE SOLVED: To provide a loading distinguishable device of a garbage truck for drainable pavement capable of deciding a cleaning velocity according to a clogging state of a drainable pavement surface. SOLUTION: The garbage truck for the drainable pavement has a water jetting nozzle 6 provided on a self-traveling vehicle 1 for eliminating clogging matters in the drainable pavement. The front and rear side clogging detecting means 15 and 25 are provided to the front and rear sides of the water jetting nozzle 6. A computer 30 as a discriminating means for comparing outputs of the front and rear side clogging detecting means 15 and 25 is provided. The detecting means 15 and 25 are respectively equipped with first and second speakers 18 and 27 oppositely to the pavement surface and first and second microphones 19 and 28 for catching a reflected sound from the pavement surface 8 by the first and second speakers 18 and 27.
