[0002] Dredging generally refers to the management of river channels, which is a water conservancy project. It involves using mechanical equipment to blow and stir up the silt deposited on the riverbed into turbid water, which is then carried away by the river flow, thereby clearing the channels. River siltation has increasingly affected the normal functioning of various functions such as flood control, drainage, irrigation, water supply, and navigation. In order to restore the normal function of river channels and promote the rapid and sustainable development of the economy and society, river dredging projects are carried out to make river channels deeper and wider, and the water clearer. This will significantly improve the production conditions and living environment of the people, achieving the goal of "clear water, unobstructed rivers, green banks, and beautiful scenery." Therefore, there is a need for dredging equipment for ecological water environment management.
