Description

A New Municipal Permeable Pavement Road Drainage Structure

technical field

The utility model relates to municipal roads, in particular to a novel municipal permeable pavement road drainage structure.

Background technique

The existing pavement structure includes asphalt, concrete, pavement brick paving, gravel pavement, etc. The surface of these roads is easy to deposit dust and dirt, and has poor water permeability and poor wear resistance; while the road surface with good wear resistance has poor drainage, when the water volume is large It is easy to accumulate water on the road, causing troubles for pedestrians and vehicles, causing a large amount of garbage to enter the sewer and block the sewer, forming a vicious circle; in some places, the amount of sewage rainwater exceeds the carrying capacity of the wastewater treatment plant, causing a large amount of untreated wastewater to directly seep into the surface with the rainwater pollution in the soil below. Due to the good water permeability and air permeability of the permeable pavement, it can save drainage space and other advantages, and it has gradually attracted people's attention. The bottom layer of the existing permeable pavement structure is the aggregate base, which is usually the permeable layer of dense graded gravel base or other aggregate base. Pavement structure, this pavement structure has disadvantages such as instability or low load strength.

Utility model content

In view of the above problems, the problem to be solved by the utility model is to provide a municipal permeable pavement road structure with high load strength, good stability and drainage effect.

In order to solve the above technical problems, the technical solution adopted by the utility model is a new municipal permeable pavement road drainage structure. The road structure includes a roadbed, a base layer, a wear layer and a drainage pipe; the base layer is located on the road base; on the base; the ground is adjacent to the road structure; and the drainage pipe is located on the bottom side of the base.

Preferably, aggregates are provided in the base layer, and the aggregates include crushed stones, and the crushed stones are compacted to form graded crushed stones, forming a graded crushed stone layer in the base layer.

Preferably, the graded crushed stone layer is a water storage layer. When the water volume is large, rainwater penetrates the road surface to form a certain buffer zone in the graded crushed stone layer, which relieves the pressure of road surface drainage and improves drainage efficiency.

Preferably, the wearing layer is composed of a permeable pavement, and the permeable pavement is one of a paved express road, a porous asphalt pavement, and a porous concrete pavement, and the water permeability is ≤125mm/h.

Preferably, when the permeable pavement is paved express pavement, a filler layer is provided between two paving blocks.

Preferably, the roadbed is an impermeable compacted roadbed; effectively maintaining the stability and strength of the road structure.

Preferably, the drainage pipe discharges rainwater in the base layer, thereby reducing rainwater seepage into the roadbed.

As a preference, there may be no drainage pipes in the road structure, and the depth of the base layer may be deepened to increase the capacity of water storage to achieve the purpose of rapid and effective drainage.

The beneficial effect of the utility model is that the structure of the utility model is easy to construct, utilizes the water permeability and air permeability of the permeable pavement, has a good drainage effect, reduces the temperature of the pavement, and reduces environmental pollution; the structure of the utility model can also be used in parking lots or other structures.
