What are the drainage structures of water conservancy and hydropower?

The following is the related contents of water conservancy and hydropower drainage structure brought by Zhong Da Consulting for your reference.

Flood discharge and drainage of reservoirs, rivers, channels and waterlogged areas that exceed the storage capacity or bearing capacity, and hydraulic structures for safety protection or maintenance of reservoirs and channels. Discharge structure is an important hydraulic structure to ensure the safety of water control projects and hydraulic structures and reduce flood disasters.

What are the drainage structures of water conservancy and hydropower?

Commonly used water conservancy and hydropower drainage structures are:

(1) Rolling dam, river sluice and sand sluice of low-head water control project;

(2) Overflow dams, spillways, spillways, culverts and tunnels of high-head water control projects;

3. Flood diversion sluice and overflow dam;

(4) discharging flood or excess water into the sluice and sluice of the canal through channels;

(five) drainage sluice and drainage pumping station, used for drainage.

China has a long history of building drainage structures. It was recorded as early as the Spring and Autumn Period and the Warring States Period. With the continuous enrichment of practical experience and the continuous development of science and technology, the forms, structures, materials, energy dissipation and scour prevention, vibration resistance, foundation treatment, construction technology and other aspects of drainage structures in the world are progressing day by day, and the scale is also expanding. The maximum discharge capacity of drainage structure of Brazil Tukurui Project is 104400m? /s, the maximum discharge of Gezhouba water control project in China reaches 1 10000m? /s, the discharge per unit width of the spillway on the bank of Menggela Water Control Project in Pakistan reaches 290m? /(s * m), the ski spillway on the right bank of Dongjiang Hydropower Station in China adopts narrow slot energy dissipation, and the initial unit width flow of narrow slot contraction section is 15 1m? /(s * m), ending in 604m? /（s * m）。
