Rainwater recovery system and construction method for sponge city overpass

Abstract

The invention discloses a rainwater recycling system for sponge city overpass and a construction method of the rainwater recycling system. The rainwater recycling system comprises a rainwater collection device, rainwater pretreatment equipment and a water storage well, the rainwater collection device comprises a rainwater pipe and a collector, a water collection pump is mounted on the collector, and the rear end of the rainwater pipe is connected onto the water collection pump while the front end of the same is connected onto a deck of the overpass; the lower end of the collector is connected with a first guide pipe, the other end of the first guide pipe is connected with the rainwater pretreatment equipment, a diverter is mounted at the lower end of the rainwater pretreatment equipment, a second guide pipe is connected on the diverter and connected to the water storage well, a submerged pump is mounted in the water storage well, and a recycling pipe is connected on the submerged pump. An existing overpass draining pipeline is introduced into the collector, and rainwater is purified with the help of the rainwater pretreatment equipment, guided into the water storage well and then recycled through the recycling pipe, so that reasonable utilization of rainwater resources is realized, city water consumption pressure is relieved, the draining problem of the overpass is solved effectively, and city traffic is guaranteed.

Description

technical field [0001] The invention relates to a rainwater recovery system, in particular to a rainwater recovery system for a sponge city overpass and a construction method thereof. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water when needed. and take advantage of it. Improve the functions of urban ecosystems and reduce the occurrence of urban flood disasters. To build a sponge city, we must first reverse the concept. The traditional urban construction model is full of hardened roads. Whenever there is heavy rain, drainage is mainly relied on "grey" facilities such as pipes, canals, and pumping stations. The main planning and design concepts are "quick drainage" and "end-centralized" control, which often results in waterlogging every rai...

Problems solved by technology

Overpasses are an important part of urban traffic. On rainy days, if the rainwater on the overpasses cannot be drained in time, it will have a major impact on urban traffic; however, there is no mature overpass rainwater treatment system in the prior art, which cannot meet the needs of timely drainage and drainage at the same time.
