Description
Technical Field
The invention belongs to the technical field of rainwater collection, and particularly relates to an urban road surface rainwater collection system.
Background
With the further acceleration of urbanization, the contradiction of urban water shortage is further deepened, and the environmental and ecological problems are synchronously expanded. China is a very water-deficient country, the current share of per capita water resources is only 1/4 of the share of per capita water resources in the world, and more than 300 cities belong to water-deficient cities. Due to the rapid development of urbanization and the enlargement of impervious areas of roads, building groups and the like, on one hand, rainwater cannot infiltrate into the ground to supplement underground water, so that the water environment and the ecological environment around the city are deteriorated; on the other hand, in heavy rain, runoff is rapidly collected to cause surface water accumulation and urban local flood.
In order to solve a series of contradictions such as water shortage, environment, ecology and the like, people begin to pay attention to the collection and utilization of rainwater, and particularly pay attention to the development and application of urban rainwater utilization technology. In order to fully collect and utilize rainwater resources, realize rainwater reclamation, conserve underground water, reduce non-point source pollution, reduce urban flood and drainage system pressure and improve and restore urban water environment, urban construction projects are matched with rainwater collection and utilization facilities, and the rainwater is mainly used for greening, road cleaning, flushing toilets, landscape environment water use, river landscape water supplement and the like after being collected and treated.
Runoff is naturally generated after rainfall, and rainwater can be recycled only by building some simple rainwater collection and storage projects, so that the method is used for urban cleaning, green land irrigation, urban waterscape maintenance and the like. At present, the urban rainwater utilization and collection technology mainly comprises three types: roof rainwater collection, urban pavement rainwater utilization and urban green land, flower bed and garden rainwater collection and storage. The urban road pavement is a good rainwater collection mode and has the advantages of low cost, convenience in implementation, quick response and the like.
Because the collection and the utilization of urban road surface rainwater have the advantages of convenience, high efficiency and the like, the urban road surface rainwater collection and utilization method has been gradually adopted in many cities, and particularly the collected rainwater is utilized for greening irrigation. The common municipal greening facilities are irrigated by using the sprinkler in the past and then irrigated by using reclaimed water through the spray head. But a special reclaimed water pipeline system is needed, the investment of disposable infrastructure is large, and the method is not economical. Irrigation greening facilities have therefore started to be carried out in some municipal construction projects by collecting rainwater on the road surface.
However, in the current practice, a number of deficiencies are found. For example, in a road surface rainwater utilization system implemented in a certain city, there are the following problems:
1. the collected rainwater is not effectively filtered, and the precipitate is retained in the rainwater to generate precipitate, so that the rainwater collection system is paralyzed due to more precipitate along with the increase of the service time;
2. through the communication between the blind ditches and the rainwater well, rainwater enters the rainwater well after being collected by the blind ditches and is blocked by garbage such as sludge and the like;
3. after the rainwater well is collected to the rainwater, take out through the rainwater well and water green planting, too extravagant manpower and materials, and the rainwater gets into the rainwater well completely, can cause the rainwater accumulation more in the rainwater well, and continuous rainfall can lead to rainwater well paralysis.
