Abstract

The invention relates to the technical field of urban construction, in particular to an ecological utilization system for purifying, regulating and storing rainwater in northern cities attached to roads. Including road central drainage green plant unit, roadside drainage unit, roadside surface green plant purification unit, underground seepage storage unit and rainwater wetland garden. The drainage and green planting unit in the center of the road in the present invention increases the water permeable area of ​​the road surface; the drainage ditch can effectively reduce the situation of garbage blocking the road drainage outlet, accelerate the drainage flow rate, and prevent snow water containing deicing agent from flowing into the green belt in winter; the sidewalk drainage ditch The installation is to introduce excessive rainwater on the road surface into the green plant purification unit on the roadside to increase the area and time of rainwater infiltration; the installation of underground water seepage storage unit realizes the storage of rainwater for later use; the rainwater wetland garden realizes the increase in rainy season Large rainwater infiltration area and rainwater retention time; the rainwater wetland gardens and roadside surface green plant purification units are connected in a ditch shape, which greatly reduces the amount and area of ​​road water accumulation.

Description

technical field

[0001] The invention relates to the technical field of urban construction, in particular to an ecological utilization system for rainwater purification, regulation and storage in northern cities attached to roads. Background technique

[0002] Sponge city is a brand-new urban construction concept proposed by the country to solve problems such as urban waterlogging, non-point source pollution, and serious damage to the urban water circulation system. Sponge city requires the city to have the functions of infiltration, stagnation, storage, purification, utilization and drainage of rainwater .

[0003] Rainfall is a very important link in the natural water cycle system, and it is a natural source of supply for rivers, lakes, ponds, artificial landscape water extraction, etc. It has obvious randomness, seasonality and unevenness, especially in northern cities. Spring and autumn are dry, and summer is rainy. During the rainy period, the city is prone to waterlogg...
