Problems solved by technology

The effect of this intervention is negative: a large amount of rainwater is lost, frequent water accumulation on traffic roads affects normal life, the peak value of rainwater floods increases and increases the load on the drainage system, soil moisture content decreases, heat island effect and groundwater table decline are exacerbated.

Embodiment 1

[0080] A road project in Hefei, Anhui Province, with a total length of 1km, adopts asphalt pavement. Hefei City is located in the central part of Anhui Province, on the edge of the subtropical zone, and belongs to the northern subtropical humid climate zone, with abundant annual average precipitation. In view of the abundant rainfall in Hefei City, this design selects a certain road section as the design road section, and collects rainfall as road cleaning water.

[0081] The total length of the designed road section is 1000m. According to the requirements, a stormwater outlet 1 is set every 50m. The rainwater of the rainwater collection system comes from the stormwater outlets 1 on both sides of the road. There are a total of 40 stormwater outlets 1, 20 on each side. The total catchment area is roughly estimated to be 40,000 square meters ㎡. Therefore, the catchment area of ​​each rainwater outlet 1 is 200 square meters, and the volume of the rainwater storage tank is calcula...

Abstract

The invention relates to a road surface flushing method based on rainwater recycling. The road surface flushing method comprises the following steps that step S1, rainwater collection; step S2, rainwater treatment and overflow; and step S3, rainwater storage and application, wherein in the step S3, the rainwater treated in step S2 is sent to a lifting pump house through a perforated pipe, the treated rainwater is lifted from the lifting pump house to a recycling pump pipe, and the recycling pump pipe is connected with the sprinklers on both sides of the road to be used for washing the road surface and reducing the dust. By means of the road surface flushing method, the invention has the advantages that compared with an existing road surface washing process, the financial expenditure of thepurchase and maintenance of a spray truck used for road washing, the loss of water resources, and the wages of the operators are eliminated, the treatment process is simplified, the control management is facilitated, and the road surface flushing method is suitable for every situations; and the road surface flushing method can save water resources to a great extent, and also respond to the national advocacy on rainwater resources utilization, and the combination of the road surface flushing method with a novel permeable road surface is the future trend of the road surface flushing method.

Description

technical field [0001] The invention belongs to the technical field of rainwater reuse, and in particular relates to a road surface flushing method based on rainwater reuse. Background technique [0002] With the process of urbanization, the ground is hardened (such as building roofs, roads, squares, parking lots, etc.), which changes the hydrological characteristics of the original ground and interferes with the natural hydrological cycle. The effect of this intervention is negative: a large amount of rainwater is lost, frequent water accumulation on traffic roads affects normal life, the peak value of rainwater floods increases and the load on the drainage system is increased, the soil moisture content decreases, the heat island effect and groundwater table decline are exacerbated. At the same time, the problem of water shortage in my country's cities is becoming more and more serious. Among the more than 600 cities in the country, nearly 400 cities are short of water or s...
