Problem description:
Does anyone know that the "South-to-North Water Transfer Project" passes through Cangzhou, Hebei Province? Urgent!
Analysis:
Eastern route scheme
The East Route Project of South-to-North Water Transfer starts from Sanjiang Camp of the Yangtze River, and the main line passes through Yangzhou City, Huaiyin City, Suqian City and Xuzhou City of Jiangsu Province, and enters Shandong Province through Nansi Lake. Shandong section starts from Nansihu Economic Ning, crosses the Yellow River Project, crosses the west side of Linqing to Dezhou, and then leaves Hebei. In Hebei, it only passes through Cangzhou City, and the "water" is divided into three roads, two of which flow into Beidawa for storage and all the way to Tianjin, the end of the eastern line.
As early as the end of 1950s, Sulu and Shandong provinces began to study the Eastern Route Plan. As a matter of fact, the North-to-North Water Diversion Project in northern Jiangsu started construction at 196 1, which lasted for 35 years, and the scale has been quite large. The South-to-North Water Transfer Project is a small watershed water conservancy project built by Jiangsu Province to solve agricultural irrigation, flood control and drought relief in northern Jiangsu Province. The Yangtze River water flows into the Grand Canal from the Sanjiang Camp along the ancient flood discharge canal where the Huaihe River seized the river into the sea in history. It goes up through 9 cascade pumping stations such as Jiangdu Station and Huai 'an Station and is sent to Weishan Lake at the junction of Jiangsu and Shandong. For Jiangsu, the East Route of South-to-North Water Transfer Project means the expansion of project scale and pumping capacity.
The key to the whole eastern route plan is the yellow river crossing project between Xieshan and Weishan in Dongping and Dong 'a counties of Shandong Province. It is necessary to dig an inverted siphon tunnel with a total length of 584 meters on the huge bedrock at the bottom of the Yellow River. After years of geological exploration, the Yellow River crossing test tunnel was successfully excavated, which is the symbol of the Yellow River crossing tunnel with a height of 2.6 meters and a width of 2.9 meters. The key technical problems of the East Route Water Transfer Project have been solved.
Generally speaking, the East Route Project of South-to-North Water Transfer is to use the original Beijing-Hangzhou Grand Canal, and on the basis of the Jiangsu River Diversion Project, pump the water up step by step to flow northward and send it to Tianjin through the Yellow River. Mainly solve the problem of water shortage in Jiangsu, Shandong, Hebei, Tianjin and other provinces and cities. Its advantages are that, based on the project of harnessing the Huaihe River and the sea, the existing water conservancy projects can be fully utilized, and comprehensive benefits such as drought resistance, flood discharge, power generation, irrigation and shipping can be brought into play, with low investment intensity and easy implementation by stages. According to experts, the more sensitive issues on the Eastern Route are the project management and the operation of multi-stage pumping stations after water transfer is polluted by regional water quality.
