Where was the Pinglu Canal dug?

The Pinglu Canal was dug at the Pingtang River mouth in Xijin Reservoir Area, Hengzhou City, Guangxi Province.

Pinglu Canal is located in the lower reaches of Nanning 15 1 km, starting from the Pingtang estuary of Xijin Hydropower Station in Hengxian County in the north. The Pinglu Canal starts from the Pingtang River mouth of Xijin Reservoir in Hengzhou City, Nanning City, and enters the Beibu Gulf along the Qinjiang River through Luwu Town of Lingshan, Qinzhou, with a total length of 134.2 km, of which the watershed crossing section is about 6.5 km, and the rest is built by using existing rivers.

Pinglu Canal focuses on developing shipping, giving consideration to water supply, irrigation, flood control and improving water ecological environment. The canal starts from the Pingtang River mouth of Xijin Reservoir Area in Hengzhou City, Nanning City, and enters the Beibu Gulf along the Qinjiang River through Luwu Town, Lingshan District, Qinzhou City, with a total length of 134.2 km, of which the watershed crossing section is about 6.5 km, and the rest is built by using existing rivers.

After the Pinglu Canal is completed, it will open up a new channel with the shortest distance to the sea for the main stream of Xijiang River, and realize the direct connection between the 5,873-kilometer inland waterway network in Guangxi and some waterways in Yunnan and Guizhou, which will greatly release the shipping advantages and potential. In the long run, it can also be connected with the Gui Xiang Canal, which is being studied and demonstrated, vertically connecting the Yangtze River, the Pearl River and the Beibu Gulf.

Significance and engineering difficulties of Pinglu Canal;

1, significance of value

Pinglu Canal is the first canal in China after the Beijing-Hangzhou Grand Canal for over 0/000 years. Focusing on the development of shipping, giving consideration to water supply, irrigation, flood control and improving the water ecological environment. After the completion of the canal, the navigation pressure in the lower reaches of the Xijiang River will be fundamentally relieved, and the navigation pressure in the Yangtze River will be relieved through the combined transport of iron and water, and it will be connected with the Gui Xiang Canal which is being studied and demonstrated in the long term. It will run through the Yangtze River, Pearl River and Beibu Gulf vertically, and better serve the southwest and central and southern regions to go south to the sea and directly reach ASEAN.

2. Engineering difficulties

Pinglu Canal will build the world's largest inland water-saving ship lock, greatly reduce the operating water consumption of the ship lock, intensively use water resources, and achieve breakthroughs in the research and development of efficient water delivery system of the ship lock, and the improvement technology of facility reliability and durability. There is a drop of about 65 meters between the water surface and the sea level of Tulip New Reservoir. In order to overcome the gap and realize the continuous navigation of ships, it is necessary to build three cascade locks. The ship lock is large in scale and complex in technology. Canal construction is also facing many challenges such as safety, high efficiency, green and wisdom.
