In order to improve the strength of the water guide pipe seat 8, the side face of the water guide pipe seat 8, which is contacted with the concrete mortar surface layer 6, the cement gravel layer 5 and the road cushion layer 3, is set to be in a circular arc shape protruding towards the center of a road, on one hand, the contact area of the water guide pipe seat 8, the concrete mortar surface layer 6, the cement gravel layer 5 and the road cushion layer 3 is increased, so that the extrusion force of the water guide pipe seat 8 in a unit area is smaller, on the other hand, the connection between two structural layers can be limited at the sunken position between every two circular arcs, thereby the connection between the two structural layers is reinforced, therefore, the stability of the road can be improved.
In order to further improve the strength of the water guide pipe seat 8, the outer surface of the bottom of the water guide pipe seat 8, which is in contact with the soil base layer 1, is provided with an inclined surface, so that the gravity height of the water guide pipe seat 8 can be reduced, the water guide pipe seat 8 is more stable, and meanwhile, more water in the soil base layer 1 can permeate into the water outlet 81 to be discharged, and the stability of the soil base layer 1 can be improved.
The road is often passed by many vehicles and large-scale vehicles, the road is subjected to adverse effects brought to the road by many pressures and environmental changes, the adverse effects can cause the detachment or horizontal slippage between road structure layers, particularly the connection between the concrete mortar surface layer 6 directly subjected to the pressure and the cement gravel layer 5, therefore, in the embodiment, a plurality of connecting strips 7 are uniformly arranged between the concrete mortar surface layer 6 and the cement gravel layer 5, and the adjacent connecting strips 7 are mutually crossed and fixed together, wherein one end of each connecting strip 7 is fixed in the concrete mortar surface layer 6, and the other end of each connecting strip 7 is fixed in the cement gravel layer 5, so that an X-shaped structure is formed, and the connection strength between the concrete mortar surface layer 6 and the cement gravel layer 5 can be reinforced.
