The Pinglu Canal connects rivers and seas and realizes the dream of connecting rivers and seas; Wudongde overcomes the problem of high arch dams and writes a miracle of dam construction; Baihetan tackles million-kilowatt power units and builds a solid foundation for clean energy; diverts rivers to supplement Han Dynasty and overcomes world-class geological problems, surging the main skeleton of the national water network.
On October 19, the online theme promotion event "Why China Shocks the World" invited the chief engineers or persons in charge of the design and construction of four major water conservancy projects, including the Pinglu Canal, Wudongde Hydropower Station, Baihetan Hydropower Station, and River Diversion to Replenish Han Dynasty, to share their original intention of participating in the Century Project to overcome world-class problems and stick to the cause.
"In order to cope with the 65-meter water level drop throughout the entire process, the Pinglu Canal Project built 'stairs' for the river and 'elevators' for the hub. Through three-level provincial pools, more than 60% of water resources were recycled, achieving navigation, water saving, The balance between the three ecological aspects." Wu Peng, the technical director of the overall design of the Pinglu Canal, said, "The canals that generations have been waiting for have finally been completed. The preliminary research is progressing, and I will continue to work hard."
Yang Zongli, the former director of the Wudongde Engineering Construction Department of the Three Gorges Corporation, said that the Wudongde Dam is tall and thin, and it is easy to crack if the temperature is not properly controlled. The builders used low-heat cement for the entire dam, combined with intelligent water supply, temperature control, and grouting to "cover the concrete with a quilt and popsicle sticks" to achieve a crack-free dam. This is the confidence that China's dam engineering technology leads the world.
"I have witnessed with my own eyes that China's hydropower nation has gone from following, running alongside, and then partially leading. I hope that the younger generation will continue to carry forward the hydropower spirit of being realistic, dedicated, and innovative and bravely scale new heights." Yang Zongli said.
Xu Jianrong, chief design engineer of Baihetan Hydropower Station, said that Baihetan Hydropower Station is located in high mountains and close to strong earthquake zones. Complex geology, huge floods, ultra-large-scale projects, and the world's first million-kilowatt hydroelectric generator set are all world-class challenges. Xu Jianrong said: "As long as we have the ambition of Jianghe, personal ideals and national needs resonate at the same frequency, the times will give us a broad stage."
Diverting the river to supplement the Han Dynasty, a long underground river was excavated from the Three Gorges Reservoir area and connected to the Danjiangkou Reservoir. It is the main artery of the national water network. The project encountered world-class geological problems such as high ground stress and high external water pressure. After the project is completed, the average annual water diversion volume of the South-to-North Water Diversion Center Line will increase from 9.5 billion cubic meters to 11.51 billion cubic meters, which is equivalent to the water supply for more than 30 million new people every year.
Li Heng, chief engineer of the South-to-North Water Diversion Middle Route Diversion Project from the Yangtze River to the Han Dynasty, said that behind the diversion of the Yangtze River to the Han Dynasty was the collaborative effort of the entire team. Major projects are national undertakings, and builders must have a sense of mission as "the great nation" and uphold the spirit of hard work and hard work.
Today's China spans mountains and rivers, relying on the hard work and technological innovation of generations of builders. The builders of great countries with important weapons are the "stars" we should pursue.
