Background
The permeable pavement is a pavement which is internally provided with a large number of through holes so that the pavement has good water permeability and can quickly allow a large amount of rainwater to permeate into the ground, thereby effectively reducing or eliminating urban rainstorm flood disasters. At present, most of urban pavements are permeable interiors. However, due to the fact that the ground silt and a large amount of suspended particles contained in surface runoff generated by rainfall continuously enter pores of the water permeable material along with water, the pores are blocked, so that the water permeability of the water permeable pavement is improved to be the non-water permeable pavement, the service life is shortened, and the possibility of urban flood and freeze-thaw disasters is increased. Therefore, the permeable pavement needs to be cleaned in time. Cleaning is currently usually by means of high pressure irrigation or vacuum suction. Wherein the high pressure flushing can not transmit the pressure to the deep part of the road surface, and the vacuum suction can generate sliding friction when the vehicle moves, so that a gap is easy to appear between the suction nozzle and the road surface, and the suction pressure is not enough. In addition, since the road surface is clogged to different degrees at different positions, if the cleaning time is uniform during cleaning, the cleaning of a part of the positions is complete.
