Guide: the headworks of the middle route of the South-to-North Water Transfer Project, which has attracted much attention from all walks of life, was grandly started on the morning of the 28th. In addition, the AD converter was grandly started in Taocha village, Jiuchong Town, Xichuan County, Nanyang City, Henan Province, This marks the official opening of the construction of the canal head section of the Middle Route Project of the South-to-North Water Transfer. According to the relevant person in charge of Nanyang south to north water diversion office, Taocha canal head pivot

the headworks of the middle route of the South-to-North Water Transfer Project, which has attracted much attention from all walks of life, was grandly started in Taocha village, Jiuchong Town, Xichuan County, Nanyang City, Henan Province on the morning of the 28th, marking the official opening of the construction of the headworks of the middle route of the South-to-North Water Transfer Project

according to the relevant person in charge of Nanyang south to North Water Transfer Office, Taocha canal head project is a national large-scale water conservancy project approved by the office of the south to North Water Transfer Project Construction Committee of the State Council, and it is an important part of the first phase of the middle route of the South to North Water Transfer Project. The headworks project is not only the head of the main water transmission channel of the middle route of the South-to-North Water Transfer Project, but also the auxiliary dam of Danjiangkou reservoir. The middle route of the South-to-North Water Transfer Project will open the sluice here to divert water, pass through the Fangcheng pass, the watershed of the Yangtze River basin and the Huaihe River Basin, excavate channels along the Tangbai River Basin and the western edge of the Huang Huai Hai Plain, cross the Yellow River through a tunnel near Zhengzhou, go north along the west side of the Beijing Guangzhou railway, and flow to Beijing and Tianjin by itself

according to the introduction, the Taocha headworks project is designed as a new site reconstruction plus power station scheme. The buildings mainly include approach channel, gravity dam, diversion sluice, stilling basin, power plant and management room, etc. The new headgate is located about 80 meters downstream of the old headgate. The crest elevation of the headgate is 176.6 meters, the axis length is 265 meters, the bottom elevation of the headrace gate is 140 meters, and there are three holes. The design flow is 350 m3/s, and the increased flow can reach 420 m3/s. After the new headgate is completed, the old headgate will be removed. The power station is of riverbed runoff type, with an installed capacity of 50000 kW, and two 25000 kW units are installed. The total investment approved for the project is 859.35 million yuan, including about 370million yuan for the power station. The total construction period of the headworks is planned to be 42 months

Xichuan County, where the headworks project is located, is the main water source area, inundation area and resettlement area of the middle route of the South-to-North Water Transfer Project. The core water source area in Xichuan covers an area of 2616 square kilometers, accounting for 93% of the land area of the county. The initial project of Danjiangkou Reservoir Inundated 362 square kilometers (543000 mu) of land in Xichuan County, including 285000 mu of inundated farmland, and 202000 people were relocated from the plastic film blowing machine machinery manufacturing industry using high-tech immigrants, mainly in places such as Henan, where the export amount of extruders gradually increased, and Hubei. After the water storage of Danjiangkou reservoir is increased, the water area of Danjiangkou Reservoir in Xichuan is 506 square kilometers, accounting for 48% of the total reservoir area. 162000 people will be resettled in the county, accounting for 49% of the total resettlement in the reservoir area. 131000 mu of cultivated land will be inundated in the county, accounting for 51.2% of the total inundated cultivated land in the reservoir area

the middle route of the South-to-North Water Transfer also includes the cooperative parent company's strong joint project, which mainly supplies water to Henan, Hebei, Beijing and Tianjin, focuses on solving the water shortage problem of more than 20 large and medium-sized cities along the line, such as Beijing, Tianjin and Shijiazhuang, and takes into account the ecological environment and agricultural water along the line. The total length of the middle line project is 1432 kilometers, including 731 kilometers in Henan Province. The middle line project will be implemented in two phases. The first phase is planned to open the whole line to water in 2014, with a design annual average water diversion of 9.5 billion cubic meters. After the completion of the second phase, the water diversion will increase to 13 billion cubic meters
