Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
As shown in fig. 1 to 3, a road green belt rainwater treatment system comprises a traffic lane road surface 1, a sidewalk road surface 2 and a green belt 3; a flat stone area 4 and a gravel area 5 are arranged between the roadway surface 1 and the green belt 3, and the flat stone area 4 and the gravel area 5 are separated by a curb 6; a lateral water inlet grate 7 is arranged on the kerbstone 6; a planting soil layer 8, ecological porous cellucotton 9 and a tamping plain soil layer 10 are sequentially arranged below the surface layer of the green belt 3 in the height direction; one side of the gravel area 5 is connected with a lateral water inlet grate 7, and partial area of the gravel area 5 is connected with the ecological porous cellucotton 9 up and down; the green belt 3 and the pavement 2 of the sidewalk are separated by a boundary stone 15; the sidewalk pavement 2 is sequentially provided with a permeable brick layer 11, a medium coarse sand layer 12, a permeable cement concrete layer 13, a gravel layer 14 and a rammed plain soil layer 10 from top to bottom.
