Urban viaduct rainwater intelligent collection and comprehensive utilization system and method

Abstract

The invention discloses an urban viaduct rainwater intelligent collection and comprehensive utilization system and method, and belongs to the technical field of rainwater collection. An intelligent rainwater collection and comprehensive utilization system for an urban viaduct comprises water collection mechanisms which are arranged on the viaduct at equal intervals and communicate with one another, each water collection mechanism comprises a water inlet pipe, a filter plate is arranged in each water inlet pipe, the bottom of each water inlet pipe is connected with a water collection tank used for storing rainwater, and a water outlet is formed in the outer wall of each water inlet pipe; an opening and closing mechanism for closing the water outlet is arranged in the water inlet pipe, the water inlet pipe is communicated with a rainwater saturation pipe through the water outlet, and the outer wall of the rainwater saturation pipe is connected with a converging pipe; according to the device, redundant rainwater can be recycled while rainwater is fully collected, green plants under the viaduct are irrigated, water resources are saved, the irrigation workload of workers is reduced, meanwhile, the filter plate is automatically replaced, and manpower and material resources are effectively saved.

Description

technical field [0001] The invention relates to the technical field of rainwater collection, in particular to a system and method for intelligent collection and comprehensive utilization of rainwater for urban viaducts. Background technique [0002] With the rapid growth of urban population density in my country, the problem of urban traffic congestion is becoming more and more serious. In order to achieve the purpose of improving the traffic capacity of urban areas, saving space and reducing construction costs, more and more cities have begun to build viaducts in urban areas. Drainage pipes are installed on the viaduct to solve the problem of water accumulation, drain the rainwater on the viaduct, and collect and utilize rainwater by setting up a water storage device. [0003] However, the water storage capacity of the water storage device is limited, especially when there is a lot of rainfall in summer. After the water storage capacity is saturated, the excess rainwater w...

Problems solved by technology

[0003] However, the water storage capacity of the water storage device is limited, especially when there is a lot of rainfall in summer. After the water storage capacity is saturated, the excess rainwater will no longer flow into the water storage device and cannot be collected, resulting in waste of rainwater. The rainwater on the surface cannot reach the green belt under the bridge, and it still needs to be irrigated on a regular basis by an irrigation vehicle, which wastes a lot of water resources, manpower and material resources. At the same time, in order to ensure the purity of rainwater collection, it is necessary to install a filter membrane in the pipeline , but the filter membrane is easy to clog during long-term use, and requires regular maintenance or replacement. Not only is the workload heavy, but there is also a certain risk of high-altitude operations
