Sponge city rainwater accumulation early warning method

Abstract

The invention discloses a sponge city rainwater accumulation early warning method, and relates to the technical field of rainwater accumulation early warning. The sponge city rainwater accumulation early warning method comprises the following steps of obtaining the real-time infiltration rate V and runoff production time T of rainwater in different sponge facilities based on an optical fiber temperature sensor in advance, and feeding back the obtained real-time infiltration rate V and runoff production time T to a data processing platform in real time, establishing a water accumulation empirical model, calculating the rainfall accumulation risk condition of each area based on the ponding empirical model, obtaining a water accumulation early warning evaluation result, and starting an urban rainwater regulation and storage facility. The real-time infiltration rate V of the rainwater on a permeable surface layer is monitored through the optical fiber temperature sensor, the rainfall runoff production time T is obtained, the rainfall condition in the current area is judged, an instruction is sent out to control a lower rainwater regulation and control facility, the water storage capacity of a sponge greenbelt is maximized, the urban flood pressure is relieved, the application range is wide, and adaptability is high.

Description

technical field [0001] The invention relates to the technical field of early warning of rainwater accumulation, in particular to a method for early warning of rainwater accumulation in a sponge city. Background technique [0002] In the construction of sponge cities today, a large number of permeable pavements and permeable concrete have been built to play the roles of water absorption, water storage, water seepage, and water purification during rainfall. Played an important role in the prevention and control of waterlogging disasters. The means of regulation and storage in the sponge city are mainly based on facilities such as rainwater adjustment pools and sponge green spaces, which absorb water bodies through infiltration, overflow, and surface collection, and absorb rainwater. dry pipe. [0003] At present, the sponge structure of the sponge city cannot fully play the role of water storage during rainfall, and the water storage such as soil has not reached the peak val...

AI Technical Summary

Problems solved by technology

[0003] At present, the sponge structures in the sponge city cannot fully play the role of water storage during rainfall, and the soil and other water storage has not reached the peak value. The rainwater is directly poured into the main pipe. Similar to the sponge structure, there is still a lot of room for improvement.
