Abstract

The invention discloses a community drainage system for alleviating urban water logging. The community drainage system comprises a residential building, a rainwater pipe network, a sewage pipe network, a riverway, a water-permeable pavement and a greening belt, wherein an inlet, a first outlet and a second outlet are formed in the rainwater pipe network, a roof water-storage area is arranged on the top of the residential building, and the roof water-storage area is communicated with the inlet through a roof sewer; a valve is arranged on the first outlet, the output end of the valve is connected with a first pipeline, and the first pipeline is communicated with the sewage pipe network; a river bottom water-storage system is arranged on the bottom of the riverway, holes are formed in the side wall of the riverway, the holes are communicated with the river bottom water-storage system, and the second outlet is communicated with the river bottom water-storage area through a second pipeline.Rainwater is temporarily stored by using the roof water-storage area, the peak discharge of a pavement in a community is alleviated, the disaster severity is reduced, the energy utilization rate is increased, the rainwater is easy to channel in many ways, water logging is avoided, and fresh water resources are saved.

Description

technical field [0001] The invention relates to the technical field of drainage systems, in particular to a community drainage system for alleviating urban waterlogging. Background technique [0002] Urban waterlogging is caused by the inability to remove the accumulated water in time after extreme rainstorms. my country is one of the countries most affected by waterlogging. Especially in recent decades, the urbanization process has accelerated rapidly, and impermeable surfaces such as squares, buildings, and roads have rapidly Increase. However, the limitation of the space and cost of the underground drainage pipe network has led to a relative disconnect with the rapid development of the city, resulting in serious water accumulation, and the phenomenon of urban waterlogging that "every rain will flood" is particularly prominent. [0003] Existing patented technologies only provide local structures to alleviate waterlogging, such as: updating the size of underground pipe net...
