In urban flood control and drainage projects, rainwater is collected and drained through a rainwater drainage pipe network, a pump gate and a river and lake system, wherein the rainwater drainage pipe network is formed by cross communication of a plurality of drainage pipes. In order to divide rainwater and sewage, a rainwater and sewage dividing well is arranged at the junction of the rainwater pipe and the sewage pipe. The rainwater and sewage diversion well is communicated with a road surface water inlet pipe, a sewage pipe and a drain pipe of a rainwater and sewage draining pipe network, and a water inlet of the sewage pipe is lower than that of the drain pipe. In the period of less rainfall, the sewage in the rain and sewage diversion well accounts for a larger proportion, and the sewage is easy to promote the propagation of the pest rats. In order to inhibit the propagation of pests and rats and the diffusion of the range of motion, and to reduce the possibility of entering the river channel due to the fact that more sewage flows into the drain pipe from the rainwater and sewage diversion well, the drain pipe of the rainwater drainage pipe network is usually provided with a baffle plate to block the range of motion of pests and rats and prevent the sewage from flowing into the drain pipe. The rainfall is usually monitored, and when a certain rainfall is reached, a baffle in a drain pipe is opened to drain the rainwater.

However, the rainfall in the drainage pipes of different cities is different due to different heights of the terrains of the cities, and the rainfall in the drainage pipes at the lower part of the terrains of the cities is usually larger than that in the drainage pipes at the higher part of the terrains of the cities. It is difficult to determine the amount of rainfall in the drain pipes at each location only by monitoring the amount of rainfall. When the amount of rainwater in the drainage pipes at the lower part of the urban terrain is large and is not monitored and discharged to rivers and lakes in time, the rainwater in the drainage pipes at the lower part of the urban terrain can be caused to flow back to the road surface, so that adverse effects on road traffic are caused.
