Please introduce the Three Gorges Dam.

The Three Gorges Water Control Project is the largest water control project in the world today and is listed as one of the super projects in the world.

It is a large-scale water conservancy and hydropower project with multiple development goals such as flood control, power generation and shipping. The whole project is expected to be completed in 2009, with a total investment of about 205 billion yuan. Upon completion, it can generate 18000 MW, which is equivalent to 18 nuclear power plants. At the same time, it will improve the shipping conditions of the 650-kilometer Yangtze River route and improve the resource transportation conditions in Central China.

The Three Gorges Dam was built on Bao Zhong Island in Sandouping. When completed, its majestic dam is 2335 meters long and 70 meters high, just like a "Great Wall on Water" across the Yangtze River.

About the Three Gorges Project

The Three Gorges Project is the largest water conservancy control project in the world today. Its indexes have broken the records of water conservancy projects in China and the world.

● It has been 75 years since the establishment of the Three Gorges Project, and it is the longest water conservancy project in the world.

● The Three Gorges Project lasted for half a century from the survey in the early forties to the comprehensive and systematic design and research in the fifties and eighties, and accumulated massive basic data and research results. It is the most well-prepared water conservancy project in the world.

● The construction of the Three Gorges Project has received the most extensive attention at home and abroad. This is the first water conservancy project deliberated and voted by the National People's Congress, the highest authority in China.

● The total storage capacity of the Three Gorges Reservoir is 39.3 billion cubic meters, and the flood control storage capacity is 2210.50 billion cubic meters. Reservoir flood regulation can reduce the peak flow by 270,000-33,000 cubic meters per second, which is the most remarkable water conservancy project in the world.

● The total installed capacity of the Three Gorges Hydropower Station is 65.438+08.2 million kilowatts, and the annual power generation is 84.68 billion kilowatts. It is the largest power station in the world.

● The backwater of the Three Gorges Reservoir can improve the 650km waterway of Chuanjiang River, so that the tonnage of the remaining fleet can be increased from the current 3,000t levee to 1 10,000t, and the annual one-way capacity can be increased from 6,543,800 tons to 50 million tons; The navigable depth of the Yangtze River in low water below Yichang is also increased by reservoir regulation, which is the most remarkable water conservancy project in the world.

● Three Gorges Project, including non-overflow dams on both banks, with a total length of 2,335 meters. The spillway dam section is 483 meters, with 700,000 kilowatts ×26 hydropower stations, double-track five-stage shiplocks and ship lifts, which are the largest water conservancy projects in the world, whether individually or collectively.

● The earth and stone excavation and filling volume of the main building of the Three Gorges Project is about 65.438+0.25 billion cubic meters, the concrete pouring volume is 26.43 million cubic meters, and the steel product is 593,000 tons (280,800 tons of metal joints installed), making it the largest water conservancy project in the world.

● The maximum water depth of the deep-water cofferdam of the Three Gorges Project is 60m, the monthly earthwork volume is 6,543.8+700,000 cubic meters, the monthly concrete volume is 450,000 cubic meters, and the monthly RCC volume is 380,000 cubic meters, all exceeding the world record, and it is the project with the greatest water conservancy construction intensity.

● The Three Gorges Project has a closure flow of 90 10 m3/s and a maximum flood peak flow of 79,000m3/s for construction diversion, which is the largest water conservancy project in the world during the construction period.

● The maximum flood discharge capacity of the spillway gate of the Three Gorges Project is 65,438+million cubic meters per second, which is the largest flood discharge capacity in the world.

● The double-line five-level lock of Three Gorges Project, with total head 1 13m, is the inland river lock with the largest number of stages and the highest total head in the world.

● The effective size 120× 18× 3.5m, total weight1kloc-0/800t, maximum lift10/3m, and tonnage of the Three Gorges ship lift is 3000t, which is the largest and largest in the world.

● In the Three Gorges Project, the number of reservoir immigrants is the largest, and the work is the heaviest, which can eventually reach one million.
