Dujiangyan is a famous ancient water conservancy project, located in the west of Dujiangyan City, Sichuan Province. Du 'an County was named Du 'an weir in ancient times. Known as Dujiangyan after the Song and Yuan Dynasties, it is known as the "treasure of Zhenchuan".
At the 24th session of the United Nations World Heritage Committee in 2000, Qingcheng Mountain and Dujiangyan were listed as world cultural heritages because of their long history, large scale, reasonable layout, scientific operation and harmonious combination with the environment. In 2006, it was listed in the World Natural Heritage List as a part of the giant panda habitat in Sichuan.
Dujiangyan is a famous ancient water conservancy project, which was built in the 3rd century BC. It is a large-scale water conservancy project built by Li Bing, the prefect of Shu County of Qin State in China during the Warring States Period. It is the oldest and only grand water conservancy project in the world, and its characteristic is that there is no dam to divert water. For more than 2200 years, it still plays a huge role.
The most important part of Dujiangyan water conservancy project is Dujiangyan canal head project, which is the key facility of Dujiangyan irrigation system. The head of the canal is mainly composed of three major projects: Yuzui diversion dike, Baojiangkou diversion project and Sha Fei weir spillway.
Sha Fei weir is the spillway in the middle section, which has the function of flood discharge and sediment discharge, and Baokou has the function of water diversion and water control. Therefore, Dujiangyan water conservancy project scientifically solved the problems of automatic diversion, automatic sediment discharge, automatic drainage and water diversion of river water, and achieved the effect of "irrigating fields with water to prevent floods and disasters", which is a great miracle in the history of water conservancy projects in the world.
