Urban viaduct rainwater comprehensive recycling system and method

Abstract

The invention discloses an urban viaduct rainwater comprehensive recycling system and method. The system comprises a pump station, a rainwater collecting device, a bridge surface spraying device, a plant irrigating device, a road surface state sensor, a rain and snow sensor and a soil humidity sensor. According to the method, the system is adopted, a PLC receives signals from the rain and snow sensor, and if it is judged that it rains, the PLC controls a water collecting electromagnetic valve and a drainage electromagnetic valve to be opened; all parts are combined into a whole through the internet of things, collected rainwater can be distributed through a PLC control system according to the actual demands of the external environment, the requirement for water spraying cooling of urban viaduct road surfaces in high-temperature weather in summer is met, and the requirement for automatic irrigation of plants under an urban viaduct is also met; meanwhile, in snowy days in winter, the PLC control system can spray deicing liquid on the road surfaces according to external temperature requirements to prevent the road surfaces from icing.

Description

technical field [0001] The invention relates to an urban viaduct rainwater comprehensive recycling system and method thereof. 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. The construction of the viaduct has improved the traffic environment, but it also faces problems such as the discharge of a large amount of rainwater during the rainy season, the high temperature of the road surface in the summer high temperature season, and the road surface is prone to ice and snow in winter. Such problems are easy to cause damage to the viaduct, and cause serious traffic accidents, and then bring huge losses to the safety of people's lives and properties. [0003] In order ...

AI Technical Summary

Problems solved by technology

These methods do not recycle rainwater very well, resulting in insufficient water resources on the one hand, but on the other hand, they are causing a large amount of water loss, which is not conducive to the sustainable development of the economy and society.
