The largest aqueduct group and pump station group of the South-to-North Water Transfer project bid farewell to Taocha canal head. The all media research team of the South-to-North Water Transfer Project of Xinhua News Agency went north to Shahe aqueduct, the world's largest aqueduct in terms of comprehensive scale. After a canal of clear water goes 241km north from the head of the canal, it continues the new journey of Shahe aqueduct along the air passage connected by hundreds of giant troughs

bid farewell to Taocha canal head. The all media research team of the South-to-North Water Transfer Project of Xinhua News Agency went north to Shahe aqueduct, the world's largest aqueduct in terms of comprehensive scale. After a canal of clear water goes 241km north from the head of the canal, it continues the new journey of Shahe aqueduct along the air passage connected by hundreds of giant troughs

this is the key project of the middle route of the South-to-North Water Transfer Project, Shahe aqueduct, Lushan County, Pingdingshan City, Henan Province, taken on May 22 (UAV photo). The middle line and east line of the South-to-North Water Transfer Project are like two "giant dragons" swimming to the north. The difference is that the east line project has the world's largest pumping station group, while the middle line project has the world's largest aqueduct group

27 aqueducts and 13 stage pump stations: the world's largest aqueduct group and pump station group

stand beside the Shahe aqueduct. It can be seen that after the water passes through the gate from the open channel, it continues to flow northward along the four huge U-shaped grooves

"this is a beam aqueduct in Shahe aqueduct. The span of the single aqueduct is 30m and weighs 1200 tons. Four aqueducts are arranged in parallel. The net width of the single aqueduct is 8m and the net height is 7.4M. At present, the flow rate is 314m3/s, the flow rate is 1.5m/s, and the water depth in the aqueduct is 6.4m." Dongzhibin, director of Lushan Management Office of the Construction Management Bureau of the middle route of the South-to-North Water Transfer Project, said that Shahe aqueduct is 9.05 kilometers long. It crosses Shahe River, Jiangxiang River and Dalang river. It is composed of three types of aqueducts: beam aqueduct, box based aqueduct and floor type aqueduct

this is the key project of the middle route of the South-to-North Water Transfer Project, Shahe aqueduct, Lushan County, Pingdingshan City, Henan Province, taken on May 22 (UAV photo). Li Mingxin, chief engineer of Henan Branch of the construction and Management Bureau of the middle route of the South-to-North Water Transfer Project, said that Shahe aqueduct is the largest aqueduct project in the world. In addition to Shahe aqueduct, there are also 26 large aqueducts such as Tuanhe aqueduct, which is the largest aqueduct group in the world

after the heightening of Danjiangkou dam, the middle route of South-to-North Water Transfer project uses Danjiangkou reservoir, the water source, to reduce the water level difference of nearly 100 meters from Tuancheng lake to Beijing. It can use xinkaiming canal to carry water to Beijing by gravity. The aqueduct has become an important part of the main canal of the middle route

different from the aqueduct group in the middle line project, I was deeply impressed by the east line pump station group when I interviewed Erzhuang pump station, the seventh stage pump station and Wannianzha pump station, the eighth stage pump station of the east line project of the South-to-North Water Transfer project more than two months ago

the east line project starts from Jiangdu water control project in Yangzhou City, Jiangsu Province, uses the Beijing Hangzhou Grand Canal and its parallel river channels to transport water, connects Hongze Lake, Luoma Lake, Nansi Lake and Dongping Lake, and serves as a regulation and storage reservoir. After the water is pumped into Dongping Lake step by step through the pump station, it continues to transport water to the north. It passes through the Yellow River tunnel through the Yellow River 1. Overview of carton detection equipment, and delivers water to Datun reservoir in Dezhou, The other way carries water to Jiaodong area

as the altitude of some northern areas along the east line is higher than the water transmission source, the south water flows to the north to realize "water flows to high places", and it can continue to flow to the North until it crosses the high points. Therefore, there is a group of pumping stations
