The road seepage layer 3 is composed of permeable asphalt mortar or permeable asphalt concrete, and has a high degree of permeability. The road seepage layer 3 can quickly guide rainwater to the road medium layer 4 and prevent water from accumulating in the road surface layer 1 to form water accumulation. The road medium layer 4 is composed of materials such as permeable gravel and permeable crushed stone, and has good permeability and bearing capacity, and can provide suitable drainage and bearing capacity for the road. The road base layer 5 is the bottom of the entire road structure, and a cement concrete base layer is usually used. In order to provide stable support and strength, when installing the filter plate 7, align the slot 12 and the block 13 so that the block 13 enters the slot 12, and then screw the first threaded rod 11.
