From the completion of the Jianghuai Canal, look at the freight volume of the Huanghan Canal
See the article for details:
According to the Jianghuai Canal, the Huanghan Canal should divert water from the Danjiang estuary, take water at the head of the canal, and dig 15 meters deep. The canal and the water diversion line are separated. The freight volume target should be greater than 150 million tons per year (annual toll at 5 billion) for the Jianghuai Canal.
The canal should dredge the north bank of the Yellow River section of the Beijing-Hangzhou Canal, and the Yellow River will flow to Tianjin and Dongying into the sea.
"Jianghuai Canal" project!
The goal is to open up the transportation channel between the two major water systems in Anhui - the Huai River and the Yangtze River.
In order to solve the problems of transportation and irrigation, the state launched the construction of the Jianghuai Grand Canal in 2016.
Strategic layout of the line
The Jianghuai Grand Canal project is divided into three sections: the southern, eastern and northern sections, and connects the Huaihe River system with the Yangtze River system through water diversion and waterway construction.
The southern section of the project starts from Wuhu, passes through Tongling and Anqing, and finally converges on the provincial capital Hefei. The southern section of the canal will effectively promote the development of economic exchanges between the north and south of Anhui and bring huge development opportunities to the region.
The eastern section of the project, known as the Wushen Canal, directly connects Wuhu with Shanghai's Pudong estuary, realizing the land and waterway route between Anhui and Shanghai.
The northern section of the project will open up the traffic arteries between the water system of the tributaries of the Huai River and the Yangtze River by dredging the rivers such as the Yinghe, the Whirlpool River and the Xifei River, which are tributaries of the Huai River. The implementation of this northern section of the project will reduce the pressure on the Beijing-Hangzhou Grand Canal and provide another important transportation route for northern China.

Engineering difficulty
The Jianghuai watershed is 46.4 meters down and the mouth width is 357 meters, which is the largest digging depth and the highest grade artificial inland waterway in China. The main trunk canal aqueduct of the Weihe River is the world's largest single-span steel structure aqueduct, forming a double interchange for shipping and water diversion; With a total flow rate of 340 cubic meters per second, the Shushan pumping station is the largest mixed-flow pumping station in Asia; The intersection of the Shanghai-Rong high-speed railway and the diversion of the Yangtze River and the Huai River was reconstructed 4.5 kilometers, which was the first time in China.
It is predicted that by 2030 and 2040, the total water transport volume of the Jianghuai Canal will reach 138 million tons and 185 million tons respectively.
The Jianghuai Canal runs through the canal, making it the second north-south water transport channel in China parallel to the Beijing-Hangzhou Grand Canal, forming the main skeleton of the "well" shaped trunk channel in the Yangtze River Delta region, leading the inland Anhui to "rise to the sea".

The Jianghuai Canal is connected to the Shaying River, the Zhonglianheyu Line, and the Wushen Canal, forming the Jianghuai Canal that runs through the three provinces of Anhui, Jiangsu and Henan, with a total length of more than 1,260 kilometers.

The Jianghuai Canal opens up the main artery of water transportation between the Yangtze River Delta and the Central Plains Economic Zone, and is the key channel for the circulation of economic factors in the Yangtze River and Huaihe River basins.

The Jianghuai Canal can not only shorten the water transportation cycle by about one-third and reduce the freight by about one-quarter, but also greatly increase the transportation volume.
According to the Anhui Provincial Department of Transportation, after the opening of the Jianghuai Canal, it can save more than 6 billion yuan in the freight of bulk goods in the hinterland every year, reduce carbon emissions by nearly 1.8 million tons per year, and reduce the logistics cost of industrial enterprises along the route by 5% to 10%.
