Description

Water permeability pavement structure

Technical Field

The utility model relates to a road structure technical field, in particular to water permeability road surface structure.

Background

The road provides very big facility for people's trip, and traditional road often is the relatively poor road surface structure of non-water permeability or water permeability, but if meet rainfall weather, the rainwater that descends on above-mentioned road surface if can not in time drain away, just can splash and play under the effect of stress, makes dirty people's clothing, shoes socks, and the ponding of pot hole department also can become the obstacle that hinders people to pass.

Therefore, in order to enhance the drainage performance of the road structure on the basis of water permeability, people often set water permeable pipes in the road to guide water flow seeping from the road surface to drainage channels on both sides of the road.

Notice for CN 206428549U's utility model discloses a water permeability gardens road surface that pipeline is difficult to warp permeates water. The utility model provides a water permeability gardens road surface, includes plain soil tamp layer, level and join in marriage metalling, coarse sand drainage layer, the concrete surface course and the decorative surface course that permeates water, be equipped with the pipe of permeating water in the level and join in marriage the metalling of permeating water, the intraductal vertical bracing piece that is equipped with of permeating water, the upper and lower both ends of bracing piece all are equipped with and permeate water the metal butt piece of intraductal wall laminating. Rainwater falling on the road surface can penetrate into the road surface. The rainwater permeating into the road surface is collected and conveyed through the permeable pipe, and the rainwater is collected and utilized. Set up vertical bracing piece in the inside of the pipe of permeating water and support the pipe of strengthening permeating water for the intensity of the pipe of permeating water is better, is difficult to by extrusion deformation. The metal butt joint piece that sets up both ends can reduce the bracing piece and permeate water between the pipe at bracing piece about for permeate water pipe can not broken by the bracing piece bursting. However, because the pipe of permeating water on water permeability gardens road surface do not set up compatible strutting arrangement and fixing device when setting up in the level is joined in marriage the metalling, so receive the skew in the complicated bending deformation and the position of just can taking place after the squeezing action of external force for its drainage performance greatly reduced makes its self impaired and shortens its life.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model discloses to prior art's not enough, provide a water permeability road surface structure, not only can strengthen permeable pavement's drainage performance, but also have longer life.

In order to solve the technical problem, the utility model discloses a technical scheme is: a water-permeable pavement structure comprises an original soil tamping layer, a first gravel layer arranged above the original soil tamping layer, a second gravel layer arranged above the first gravel layer, a water-permeable cement concrete layer arranged above the second gravel layer and a water-permeable asphalt concrete layer arranged above the water-permeable cement concrete layer, wherein a drainage module is arranged between the first gravel layer and the second gravel layer;

the drainage module comprises a water permeable mounting frame arranged in the first gravel layer and the second gravel layer, a fixing unit arranged on the water permeable mounting frame, and a drainage pipe arranged in the water permeable mounting frame;

the fixed unit comprises a first mounting plate arranged at the lower end of the water permeable mounting frame, a pin rod arranged at the lower end of the first mounting plate and inserted into an original soil tamping layer, a second mounting plate arranged at the upper end of the water permeable mounting frame, a fixed rod arranged at the upper end of the second mounting plate and inserted into a water permeable cement concrete layer, and an extending transverse rod arranged on the fixed rod.

Furthermore, the upper end of the drain pipe is provided with a notch for water flow to pass through.

Furthermore, a guide plate for guiding the flow direction of water flow is arranged at the bottom of the water discharge pipe.

Further, the shape of the guide plate is an inverted V-shape.

Further, the shape of the guide plate is an arc shape.

Furthermore, the drain pipe and the mounting bracket joint that permeates water, be provided with the installation cavity that suits with the drain pipe in the mounting bracket that permeates water.

Furthermore, the end part of the drain pipe is fixed with the water permeable mounting frame through a screw.
