Sponge city seepage drainage structure and water circulation system

Abstract

The invention relates to the technical field of sponge cities, in particular to a sponge city seepage drainage structure and a water circulation system. The sponge city seepage drainage structure andthe water circulation system comprise a hollow drainage well, the bottom of the drainage well communicates with a municipal drainage system, a first filter screen is arranged on the upper surface of the drainage well, a driving motor is arranged on the inner wall of the drainage well, a rotating shaft is coaxially arranged on an output shaft of the driving motor, a second filter screen is arrangedin the drainage well, the aperture of the second filter screen is smaller than that of the first filter screen, the rotating shaft is located between the first filter screen and the second filter screen, a hollow garbage well is arranged on one side of the drainage well, a discharge port is formed between the drainage well and the garbage well, one end of the second filter screen is located at the edge of the discharge port and lower than the other end of the second filter screen, a cover plate is arranged at the top of the garbage well, and a collecting box is arranged in the garbage well. The system can classify garbage in rainwater so as to indirectly improve the utilization rate of the rainwater, and therefore the effects of energy conservation and environmental protection are achieved.

Description

technical field [0001] The present application relates to the field of sponge cities, in particular to a sponge city seepage drainage structure and water circulation system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". To build a sponge city, coordinate the use of natural ecological functions and artificial intervention functions, effectively control rainwater runoff, and realize the urban development mode of natural accumulation, natural infiltration, and natural purification, which is conducive to restoring urban water ecology, conserving water resources, and enhancing urban waterlogging prevention capabilities. Expand effective investment in public goods, improve the quality of new urbanization, and promote the harmonious development of man and nature. [0003] At present, the e...

Problems solved by technology

Temporary pumping and drainage is required, which affects the normal operation of the city and also causes huge economic losses

[0004] However, when building a sponge city, during the process of rainwater infiltration, collection and recycling, since the rainwater collected on the surface of the ground contains garbage, it is not convenient to separate and clean the garbage in the rainwater when filtering the rainwater. Therefore, It reduces the collection and treatment capacity of garbage, making the rainwater filtration efficiency low, thereby reducing the recycling rate of rainwater, so it needs to be improved
