[0002] Hydraulic desilting is the use of hydraulic power to remove river silt. High-pressure water from rivers or other water sources is pumped out through water pumps and other equipment to impact the silt to form slurry, which is then transported to a designated location for treatment using natural water flow or artificial drainage channels.
[0003] In the actual dredging process, due to the long use time of the river channel and the thick silt layer at the bottom, the silt at the bottom is relatively compact under the action of gravity.

In addition, hydraulic dredging consumes a large amount of water. After the water and silt are mixed to form slurry, the slurry is relatively thin and soft. The thin and soft mud flows and spreads out at the bottom of the river channel, resulting in a shallow mud depth, which makes it inconvenient to use the sludge suction pump.
