10. A method for maintaining a pervious concrete paved structure according to any one of claims 1-9, comprising the steps of:
the reservoir receives the infiltration water of the pervious concrete layer;
the water pump pumps the lower seeping water in the reservoir to a washing spray head and a water spraying opening of the brush roller;
the flushing sprayer sprays the downward seepage water towards the upper surface of the pervious concrete layer to flush and clean the plugs in the pores on the upper surface of the pervious concrete layer and maintain the humidity of the pervious concrete layer;
and starting the electric roller, wherein the electric roller rotates to drive the brush hair roller to rotate, the brush hair roller rolls to sweep the lower surface of the pervious concrete, and the water spray nozzle of the brush hair roller is sprayed to the lower body towards the lower surface of the pervious concrete so as to flush and clean the blockage in the pore space of the lower surface of the pervious concrete.
