Today, my mother and I came to yichang.
First of all, we live in the longquan mountain villa. The scenery here is good, is across the Yangtze river and the lower LaoXi, xiling gorge.
The next day, we went to the gezhouba dam. Let me introduce the Yangtze river gezhouba: Yangtze river gezhouba water conservancy hub project, is the first river in our country, the first large scale hydropower projects built on the Yangtze river. The project and its permanent equipment all by our country.the design, construction, manufacturing and installation.
The gezhouba project is located in the Yangtze river three gorges export, in yichang, hubei province. After the Yangtze river the three gorges ends at nanjinguan, suddenly open, river by broadening abruptly three hundred meters to three hundred meters. The gezhouba and by the river on the river xiba two island is divided into three shares, from right to left, referred to as the great river, jiang and the sanjiang, respectively. Great river is the main channel of the Yangtze river, navigable all the year round, two jiang and the sanjiang only in the flood water. Gezhouba water conservancy hub is built in which.
The gezhouba project is mainly composed of locks, power plants and discharging sluices, sluice and the water retaining structure.
Dam, the dam, 47 meters high total length of 2595 meters, control river basin area of 100 square kilometers, the total capacity of 1.58 billion cubic meters. Excavation backfilling conditions of 111.3 million cubic meters, the whole project of eleven million one hundred and thirty thousand cubic meters of concrete, the installation of metal structure of 77500 tons.
The gezhouba project building three locks in the three rivers and river, in one way through capacity of 20 million tons recently, forward is up to 50 million tons. 2, no. 3 shiplock head bay bridge set activity. Crest road and rail. In rivers and two each a massive runoff hydropower station, a total of 21 sets, total capacity of 2.71 million kilowatts, the average annual output of 14.1 billion degrees. A discharge sluice in two massive, three rivers and river each building a sluice, all open, is safe to vent in the history of the Yangtze river flood largest 110000 cubic.
Gezhouba dam construction in two phases.
First phase of the gezhouba water conservancy construction in the three rivers and two river. One phase of the project includes two river power plant, discharge sluice and sanjiang 2, 3 two locks, sluice and so on five big buildings and other water retaining structure.
Yangtze river gezhouba water conservancy construction, not only for industrial and agricultural production to provide strong power in central China, and effectively improve familiar gorge channel, at the same time for the construction of the Yangtze river three gorges water conservancy hub project, China's largest accumulation of test, improve technology, training team.
On the third day, we visited the world's largest water conservancy hub project, the three gorges.
The three gorges project mainly include blocking river dam, hydropower station, such as lock composed of three parts.
We went to visit the Yangtze river three gorges project target figure and original geomorphological map to recognize the three gorges dam site of three gorges project being built at zhongbaodao island as "hard granite rock mass", is the most ideal to build the dam dam site.
And I looked at the three gorges project night scene graph, the three gorges of the night view is very beautiful!
We really great, even the waves of the Yangtze river can be under control.
