Background technique

River dredging generally refers to the treatment of river channels, which belongs to water conservancy projects. At present, there are many ways to dredging river channels: the most common method is to use mechanical equipment to blow and stir the silt deposited on the bottom of the river into turbid water, which will flow away with the river. Thereby playing a role of dredging. However, this method has higher requirements on the water flow speed, and this method of dredging is a temporary solution rather than a permanent solution. It only transports the sludge at a certain position downstream, and the sludge itself does not decrease, and it will still be in a certain downstream water flow. The accumulation of silt at low places leads to the accumulation of silt, and when the river is dredged, warning signs are needed to warn passing pedestrians and vehicles.
