Abstract

The invention discloses an urban viaduct rainwater comprehensive recycling system based on PLC control. The urban viaduct rainwater comprehensive recycling system based on PLC control comprises a pumpstation, a rainwater collection device, a bridge deck spraying device, a vegetation irrigation device, a pavement state sensor, a rain and snow sensor and a soil humidity sensor. According to the urban viaduct rainwater comprehensive recycling system based on PLC control, a water drainage electromagnetic valve is also connected to the bottom of a rainwater collector; the water drainage electromagnetic valve is connected with a PLC; a pressure sensor and a flow sensor are arranged on a spraying pipeline; and the pressure sensor and the flow sensor are both connected with the PLC. According tothe urban viaduct rainwater comprehensive recycling system based on PLC control, water spraying and cooling on a viaduct pavement in high temperature weather in summer are satisfied; automatic irrigation of vegetation under a viaduct is also satisfied; and meanwhile, when it snows in winter, a PLC control system can spray a deicing fluid to the pavement according to outside temperature demand so as to prevent the pavement from icing.

Description

technical field

[0001] The invention relates to an urban viaduct rainwater comprehensive recovery and utilization system. 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 to s...
