The stills of the documentary "Crane Dancing on the Yangtze River". On December 20, 2022, all 16 million kilowatt units of Baihetan Hydropower Station will be put into operation for power generation. Baihetan and Wudongde, Xiluodu, Xiangjiaba, Three Gorges and Gezhouba hydropower stations are "linked by beads", lighting up the world's largest clean energy corridor, and injecting surging green energy into the new journey to implement the "two mountains" concept and the "double carbon" goal. The documentary "Crane Dances on the Yangtze River" presents the birth background and construction process of this super project in a panoramic way, leading the audience to deeply experience the Chinese wisdom, Chinese spirit and Chinese power behind the "green miracle". The world's first million-kilowatt water turbine unit, the world's largest underground powerhouse, and the world's most "smart" intelligent dam... Baihetan Hydropower Station has overcome 40 world-class problems, obtained more than 1000 technical patents, and achieved 100% localization of the unit. This is another masterpiece of China's hydropower equipment manufacturing from "follow", "run together" to "lead". The breakthrough of core technology is both climbing and relay. After more than half a century of site selection, 10 years of survey and design, and more than 10 years of construction, the hydropower station bears the glory and dream of several generations of hydropower people. "Crane Dancing on the Yangtze River" begins with the site selection and preparation. It captures the moving stories of breaking through and seizing the pass with real camera, leaving precious image data and historical information. As a highly professional project subject documentary, how to use the image language to excavate and present the project value artistically, so that the audience can be shocked and stimulate more emotional resonance? The film has made many beneficial attempts. Present the beauty of science and technology in vivid and appropriate language. A super project is an exquisite industrial art, which embodies the extraordinary imagination and creativity of engineers. Use an iron ball to "play with strength" to realize the upper layer blasting while protecting the bottom bedrock; Through precise blasting at the level of "sculptor", the rock crane beam was shaped at one time, creating a solid "arm" capable of bearing 10000 tons of weight for the huge underground palace; Use low-heat cement to solve the problem of "no dam without crack" and successfully build a "seamless dam"; Lay a layer of smooth "mirror" on the rock wall of the spillway tunnel to block the cavitation effect and make the "depth bomb" nowhere to live; The water outlet design of "two dragons playing in the water", which is full of traditional cultural implications, cleverly dissipates the potential energy of flood discharge... The documentary transforms scientific and technological terms into daily language, interprets complex problems in an easy-to-understand way, breaks professional barriers, and endows hard-core technology with romantic poetry. Write the road of struggle with ordinary and moving stories. What impressed the audience was not only the magnificent and beautiful dam, but also the selfless dedication of tens of thousands of builders and 100000 immigrants. The engineers in charge of exploration in the early stage risked their lives and walked on the white crane post road with a vertical drop of nearly 1000 meters and a narrowest point of less than 1 meter; Among the seven color cable cranes above the river valley, the female drivers of the same color lift 1 million cans of concrete day and night with women's attention and attention; Regardless of illness, Liu Zuxiong, a migrant worker, carried out a detailed household survey, formulated a resettlement plan, and worked hard to lead the migrants in the reservoir area out of poverty for generations... The documentary takes project construction as the theme, but the key perspective is always human. work
