Urban anti-waterlogging drainage system

Abstract

The invention provides an urban anti-waterlogging drainage system comprising a drain pipeline, a tee, a one-way valve, a water pump and a drain pipe. Three openings of the tee are communicated with the drain pipeline, the one-way valve and a water inlet of the water pump through pipelines, respectively. A water outlet of the water pump is connected with the drain pipe. The urban anti-waterlogging drainage system has the advantages that when river water level is low, urban water can be discharged through the one-way valve; when the river water level rises and exceeds the drain pipeline, the water in the drain pipeline cannot be discharged out of the drain pipeline, and meanwhile, the one-way valve closes to prevent the river water from flowing backward into the drain pipeline; if a float water level switch senses a water level anomaly, the water pump in a pump house is started, the water in the drain pipeline is pumped and discharged to a river channel through the water pump; chances that urban waterlogging occurs can be effectively slimmed, and drainage speed of urban flood can be effectively quickened.

Description

technical field [0001] The invention belongs to the field of municipal water supply and drainage, and in particular relates to an urban waterlogging prevention and drainage system. Background technique [0002] With global warming, extreme weather is becoming more and more frequent, and extreme rainfall tends to be more and more intense. Today, with the rapid development of cities, most of the original ponds, ditches, depressions, green spaces, etc. are replaced by buildings, roads and other impermeable hardened ground, which greatly weakens the ability of the surface to absorb and retain rainwater. Most of the rainwater They have to be drained through the drainage system. As a result, when many cities encounter heavy rainfall, the drainage system is overwhelmed. The water in the drainage pipes cannot be discharged to the river in time. The safety of life and property poses a great threat. Contents of the invention [0003] The problem to be solved by the invention is to...
