The picture shows the Lianghekou Hydropower Station
Is it true to build a bird's nest on a 3,000-meter high hill? It turns out that China has completed a world-class super project, which is the Lianghekou Hydropower Station Project, so how difficult is the construction of this hydropower station? According to experts, this power station is the largest hydropower station project currently being carried out in Tibet in China, and has the highest earth-stone dam in China at 295 meters, and the entire dam took 7 years to complete, using steel equivalent to the amount of steel used in Beijing Bird's Nest.
Nowadays, China's hydropower development projects have penetrated deep into the southwest region, and have also begun to enter Tibetan areas, to know that the local long-term inconvenience of transportation, not to mention large hydropower station projects, even ordinary small and medium-sized projects, construction here is very inconvenient, because of the lack of local factories, in the absence of perfect roads, external building materials and large construction equipment is almost difficult to reach the site, all the vast majority of projects here, can only rely on the background of manpower, construction difficulty can be imagined.

But now China is no longer what it used to be, with strong construction capabilities, has won the title of infrastructure demon, and the road and railway has also been built to the great southwest region, which also makes the construction of large hydropower stations possible, the Two Rivers Estuary Power Station is located on the Yalong River, because there are tributaries qingda River confluence, so named Two Rivers, which also allows the power station dam to be completed, can have a huge reservoir, plus 295 meters high earth and stone dam, can give the reservoir area a huge amount of water energy, very convenient for the power station to generate electricity, Six 500 MW generators have been installed here, with a maximum installed capacity of 3,000 MW, which can achieve an average annual power generation of 11 billion kWh, which is enough to meet the electricity needs of a medium-sized city.
This is only the power generation effect of a hydropower station in the mouth of the two rivers, to know that after the completion of the dam, the impact will be the entire Yangtze River Basin, to know that the power generation of the hydropower station is actually affected by the flow is relatively large, and the rivers in China, there are obvious flood periods and dry periods, in the abundant water period, due to sufficient precipitation, so the flow of the river is generally larger, at this time the power generation is sufficient, but if you go to the dry area, the reservoir capacity declines, the power generation will be reduced accordingly, and it is very important to ensure the flow of the Yangtze River.
Lianghekou Hydropower Station is located in the upper stream of the Yangtze River Basin, where water energy is stored, and when the dry water period is dry, it can effectively replenish the capacity of the downstream reservoir, which can ensure the power generation of a series of hydropower stations including the Three Gorges of the Yangtze River, this impact will be difficult to estimate, at the same time, after the flow is improved, the impact on the Yangtze River waterway is also very favorable, after all, this river has become the most important inland waterway in the world, and enough flow can ensure that thousands of tons or even tens of thousands of tons of giant ships are unimpeded on different Yangtze River waterways.
Of course, the construction difficulty of this dam is also very high, after all, it is a hydropower station project that can obtain the title of the highest earth-rock dam in China, and in the world, this dam can also be ranked, and the dam is not built high enough, it must also be able to withstand the huge water pressure in the reservoir area, and there can be no problems in the design life, and there have been cases in foreign countries because the dam design is not up to standard, resulting in the overall collapse of the dam body, but the Chinese people can fully trust the Chinese engineers and construction team. It is believed that in the future use of this dam, it will inevitably play an immeasurable role in the field of west-to-east power transmission and economic construction in the western region.
