Description

technical field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a dam body structure for overflow and blockage prevention of water conservancy engineering facilities. Background technique

[0002] At present, projects built to control and deploy surface water and groundwater in nature to achieve the purpose of eliminating harm and rejuvenating benefits are also called water projects; water is an indispensable and precious resource for human production and life, but its natural state It does not fully meet the needs of human beings. Only by building water conservancy projects can water flow be controlled, floods prevented, and water volume adjusted and distributed to meet the needs of people's lives and production for water resources. Common overflow dams are generally made of concrete Or mortar masonry, according to the type of dam, there are overflow gravity dam, overflow arch dam, overflow pier dam and overflow earth-r...
