Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the drainage protection structure for the mountain bidirectional unequal-height road comprises an upper layer road 1 and a lower layer road 2, wherein a fall is formed between the upper layer road 1 and the lower layer road 2. A highway retaining wall 4 is built between the upper highway 1 and the lower highway 2, and the side wall of the highway retaining wall 4 close to the lower highway 2 is in a slope shape. The outside of upper highway 1 has fixedly pour concrete anticollision wall 3 along 1 length direction of upper highway, and the roof of highway barricade 4 is located the outside of anticollision wall 3, has excavated along 1 length direction of upper highway and has planted the ditch, and it packs earth to plant the ditch to have tall and big street tree, and the street tree is along planting a plurality of even interval distribution of ditch length direction, and it is planting district 7 to plant the ditch open range promptly.

As shown in fig. 3 and 4, the upper highway 1 is excavated with a water chute 71 along the width direction thereof, one end of the water chute 71 is connected to the planting ditch in the planting area 7, and a plurality of water chutes 71 are uniformly arranged on the upper highway 1 at intervals, and are used for guiding the accumulated water on the road surface to flow into the planting area 7 to water the trees and keeping the road surface of the upper highway 1 dry. In order to avoid the bumping of vehicles when passing through the water chute 71, a filter plate 72 with meshes is embedded at the upper opening of the water chute 71, and the top wall of the filter plate 72 is flush with the road surface of the upper highway 1.

As shown in fig. 1 and 2, a water retaining slope 5 is arranged at the top of the road retaining wall 4 and at the edge position far away from the upper layer road 1, and a slope surface is arranged at one side of the water retaining slope 5 close to the upper layer road 1. The road retaining wall 4 is further provided with a passive protective net 9, and the passive protective net 9 comprises a supporting rod and a steel wire mesh. The bracing piece slope is fixed buries underground at the top of highway barricade 4, and the bottom and 4 fixed connection of highway barricade, top of bracing piece are to keeping away from 1 direction tilt up of upper highway. The bracing piece has many along 4 length direction evenly spaced distributions of highway barricade, and the wire net is fixed mutually between two adjacent bracing pieces. In order to increase the protective performance of the passive protective screening 9, an anchor cable 91 is further arranged on the passive protective screening 9, one end of the anchor cable 91 is fixedly connected to the top wall of the highway retaining wall 4 through a bolt, and the other end of the anchor cable 91 is fixedly connected to one end, far away from the highway retaining wall 4, of the supporting rod on the passive protective screening 9.
