Technical Field
The invention relates to the technical field of hydraulic engineering, in particular to hydraulic engineering equipment for limiting river channel flow.
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 to human production and life, but the naturally existing state of the water does not completely meet the needs of human beings, and only when water conservancy projects are built, water flow can be controlled, flood disasters are prevented, and water quantity is regulated and distributed to meet the needs of the people's life and production on water resources.
In hydraulic engineering, often need carry out the current-limiting to the river course, guarantee that the rivers of low reaches are mild, and the current-limiting method is the mound and stops the body, and this kind of method can't be adjusted the river course current-limiting, and when river course rivers velocity of flow changes, the unit flow of river course can be along with changing, so need design one kind can be according to the river course velocity of flow change and adjust the water yield of intercepting face and prescribe a limit to the equipment, guarantee the flow stability of river course.
