Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1, the present embodiment provides a road drainage structure, which includes a road base layer 1 and a road surface layer 2 disposed on the upper end of the road base layer 1, wherein a road edge 3 is disposed on the side of the road surface layer 2, the lower end of the road edge 3 is lower than the upper end of the road base layer 1, a drainage ditch 4 is disposed on one side of the road edge 3 away from the road surface layer 2, a ditch cover 5 is disposed on the upper end of the drainage ditch 4, a seepage ditch 6 is disposed below the road edge 3, the seepage ditch 6 is filled with gravel, a plurality of seepage pipes 41 are disposed at intervals along the length direction of the drainage ditch 4 on one side of the side wall of the drainage ditch 4 close to the seepage ditch 6, one end of each seepage pipe 41 is communicated with the drainage ditch 4, and the other end of each seepage pipe extends into the seepage ditch 6, so that auxiliary drainage can be performed by means of a roadside drainage ditch, and the drainage quantity is large, and can meet the drainage requirement of strong rainfall, and when water is accumulated on the surface of the road surface layer in the conventional rainfall amount, the water can be drained into the drainage ditch through the combination of the seepage ditch and the seepage pipe.
