Description

Permeable pavement structure

Technical Field

The utility model relates to the field of roads, in particular to a permeable pavement structure.

Background

Elevated roads (also called viaducts) are built on roads in many cities at present, lanes of the roads can be greatly increased by building the viaducts, the passing speed of vehicles is increased, but the existing viaducts are drained by drainage wells at edges of two sides, so that the viaducts are extremely prone to the situation that water accumulation occurs on the road surface due to unsmooth drainage when a short-time heavy rainfall occurs, and the vehicle passing capacity of the viaducts is greatly reduced due to the fact that the water accumulation occurs on the road surface.

SUMMERY OF THE UTILITY MODEL

The utility model provides a permeable pavement structure aiming at the problems.

The technical scheme adopted by the utility model is as follows:

the utility model provides a permeable pavement structure, includes the pontic, the pitch layer and a screen cloth section of thick bamboo of permeating water, the pontic is the reinforced concrete pontic, the pitch layer that permeates water is laid on the pontic, the through-hole has been seted up on the pitch layer that permeates water, the mounting hole has been seted up on the pontic, the through-hole with mounting hole UNICOM, a screen cloth section of thick bamboo is placed in the mounting hole.

Among this kind of permeable pavement structure, through laying the permeable asphalt layer on the pontic, make the water droplet can the infiltration when falling on the permeable asphalt layer, can let the surface of the water seepage flow reverse pontic like this, the water seepage flow can converge to mounting hole department after the pontic on the surface, water just can be discharged smoothly like this, the existence of through-hole on the permeable asphalt layer then can be convenient for water to flow away from the mounting hole, the speed that water infiltrated in the permeable asphalt layer can be accelerated to two, the effect of a screen cloth section of thick bamboo is the support through-hole, ensure that the through-hole can not collapse under the pressure of vehicle.

The specific permeable asphalt layer is an asphalt pavement with a porosity of 20%.

In conclusion, the pavement structure can quickly drain accumulated water on the surface of the asphalt layer, and ensures that the accumulated water cannot be accumulated on the surface of the asphalt layer.

Optionally, the number of the through holes is multiple, and the distance between two adjacent through holes is 1.5 m-2 m.

Since the width of a single lane is 3.5m to 3.75m at present, every other through hole (every other through hole corresponds to one mounting hole) is arranged to improve the drainage efficiency as much as possible.

Optionally, the through hole is a circular through hole, and the diameter of the through hole is 10 cm-12 cm.

Because the width of the tire of the current vehicle is about 195mm, the aperture of the through hole is smaller than the width of the tire, so that the vehicle vibration caused by the tire in the running through hole can be reduced.

Optionally, the cover plate is further included, and the cover plate is arranged at the hole of the through hole.

The cover net plate is arranged to cover the through hole, so that the phenomenon that sundries such as branches and leaves fall into the through hole to influence the drainage speed is avoided.

Optionally, a step is arranged at the orifice of the through hole, and the cover mesh plate is clamped at the step of the through hole.

The step is provided for facilitating the installation of the cover screen plate.

Optionally, the water draining pipe is installed on the installation hole.

The specific drain pipe is a PVC plastic pipe.

Optionally, a conical chamfer is arranged at the orifice of the mounting hole.

The conical surface chamfers have two functions, one is to reduce the difficulty in dismounting the PVC plastic pipe, and the drainage pipeline on the viaduct needs to be replaced and maintained at intervals; and secondly, the rainwater can be conveniently converged to the mounting hole, so that the rainwater can be quickly discharged.

Optionally, the screen plate is arranged at the hole of the mounting hole and used for separating the mounting hole from the through hole, broken stones are paved in the through hole, the particle size of the broken stones is 2 cm-3 cm, the broken stones are located in the screen cylinder, and the hole depth of the through hole is larger than 8 cm.

The hole depth of through-hole is the thickness on the pitch layer that permeates water promptly, the hole depth when the through-hole reaches more than 8 centimetres, if there is not the solid support, then even there is a screen cloth section of thick bamboo, the through-hole still probably appears the part and sinks under the effect of vehicle, so set up end otter board, end otter board's effect is the support rubble, the existence of rubble can play good support to the pore wall of through-hole like this, ensure that the through-hole can not sink, and because the particle diameter of rubble has reached 2 ~ 3cm, so can guarantee that the through-hole has good gas permeability that permeates water, can not influence the particulate matter whereabouts.

Optionally, the screen cylinder is made of engineering plastics, and the bottom screen plate is made of metal.

When the gravel is placed in the screen cylinder, the screen cylinder made of plastic can be used.

Optionally, the screen cylinder is made of metal, and the depth of the through holes is not greater than 6 cm.

When the thickness of the permeable asphalt layer is not more than 6cm, the metal screen cylinder can be directly adopted to support the through hole, and the through hole is ensured not to collapse.

The permeable pavement structure to be explained is not only suitable for viaducts, but also suitable for urban roads.

The utility model has the beneficial effects that: accumulated water on the surface of the asphalt layer can be quickly discharged, and the accumulated water on the surface of the asphalt layer is prevented.
