Embodiment 1

[0022] When it rains, the surface runoff rainwater collected by the urban road 1 enters the rainwater well 2 and flows into the seepage well 4 through the diversion pipe 3. After entering the seepage well 4, the rainwater flows into the rainwater stagnation slow-seepage layer 6 through the water hole, and the rainwater stagnation slow-seepage layer 6 The filler with larger porosity is filled inside. With the increase of rainfall time, the liquid level in the rainwater retention and slow seepage layer 6 gradually rises. When the liquid level rises to the rainwater pipe 5, the rainwater enters the rainwater pipe 5 and is discharged into the municipal rainwater pipe network. The rainwater remaining in the rainwater retention and slow-seepage layer 6 then slowly infiltrates and countercharges the groundwater during the non-rainfall period.

[0023] The average annual rainfall in a certain area is 556mm, and the lowest temperature in winter is -28℃. According to the characteristics...

Abstract

The invention relates to an urban road rainwater detention and seepage system applicable to the North. The system comprises a rainwater well, a diversion tube, a seepage well, a rainwater detention and slow seepage layer and a rainwater tube. The system is characterized in that rainwater collected by the rainwater well in an urban road during rainfall flows into the seepage well in the green belt nearby the road through the diversion tube, and seeps into the rainwater detention and slow seepage layer, and surplus rainwater is drained into a municipal rainwater pipe network. The system effectively solves the problems that lots of urban roads are hardened at present, the urban rainwater runoff volume is large, the roadbed is easy to damage in winter after rainwater seeps down in cold northern regions and the like.

Description

technical field [0001] The invention specifically relates to a rainwater retention and infiltration system suitable for urban roads in the north, and belongs to the technical field of rainwater retention regulation and storage. Background technique [0002] In recent years, Chinese cities have been frequently hit by heavy rainstorms every summer. The main reason for this is that the proportion of impermeable pavement in Chinese cities is large. In urban construction, many cities use a large number of cement, asphalt, concrete and other closed surfaces to replace the original soil surface; for public places such as sidewalks, open-air parking lots, courtyards and squares, they also like to use neat and beautiful stone slabs or cement color. brick laying. While the closed surface improves the traffic and road conditions and beautifies the environment, it also has significant adverse effects on the urban ecology and climate environment: (1) The proportion of impermeable paveme...
