Description

Rainwater harvesting ecological pavement with curbstones for water filtration and purification

technical field

The invention belongs to the technical field of sponge city and road construction, in particular to a rainwater collection ecological road surface with curb stones for filtering and purifying water.

Background technique

Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed.

Curb stone is a kind of road edge building accessory commonly used in the process of road construction. It is generally used as a strip stone set on the edge of the road surface and separated from other structural belts, so it is also called "curb". In the process of road construction The application is also very extensive. Traditional curbstones only serve to divide the area and block road drainage and road garbage, but they are also prone to obstacles to road drainage, especially in southern regions with more rain, which can easily cause rainwater to accumulate in rainy days and large areas of water on the road surface , is not conducive to the smooth flow of roads, resulting in urban flood disasters.

In recent years, road runoff pollution has attracted more and more attention. Rainwater and road cleaning water are the main sources of road runoff pollution. In addition to the conventional pollutants SS, COD, N, and P in the runoff of the road surface, there are also heavy metals (such as Pb, Cd, Zn, Cu), grease pollutants and petroleum pollutants, etc. In the traditional road drainage method, the runoff from the road surface is generally discharged directly into the urban drainage system, receiving water body or surrounding soil through the urban rainwater pipe network after collection, causing a large amount of water and soil pollution and greatly reducing the environmental quality.

At present, when the heavy rain comes, the permeable pavement cannot quickly absorb and store water, resulting in a large amount of rainwater loss, thus failing to achieve the purpose of water seepage and water purification, and may cause huge disasters.

To address the shortcomings in the prior art, it is necessary to invent an inventive and novel structure or device.
