Background

Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in the nature to achieve the purposes of removing harmful substances and benefiting benefits, and is also called 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 various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims. The object can be divided into: flood control engineering for preventing flood disasters; the irrigation and water conservancy project which prevents drought, waterlogging and serves agricultural production is also called irrigation and drainage project; converting water energy into electric energy; channel and port projects that improve and create shipping conditions; urban water supply and drainage works serving industrial and domestic water, and treating and removing sewage and rain water. Hydraulic engineering need use the metal pipeline when carrying water, at hydraulic engineering pipeline in the operation process, can corrode and rust on the pipeline outer wall, just so need remove the rust to the pipeline outer wall, if do not remove the rust, probably make the pipeline corrode more seriously.
