Therefore, the efficient, safe and reliable silt filtering equipment becomes an important component of the silt filtering equipment.
Hydraulic engineering is one of the great projects at present, and the problems of treating river silt are included in the hydraulic engineering. Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harmful substances and benefiting. Also known as water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build different types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition tanks, rafts, fishways and the like to achieve the aims, natural resources and people's living needs are in a stable state, but muddy water containing a large amount of silt is not beneficial to the operation of the hydraulic facilities.
