In the northeast of the country, the Jinsha River that has been rushing to the endless rush split the mountain into two and a half. One of the surnames is SichuanSugar baby and the other one of the surname is Yunnan. On the border between Sichuan and Yunnan provinces, a “big thing” rose up, like a rising storm, attracting the eyes of countless geological experts, motivational scholars and engineering academicians. It was also named as a model of the national important equipment of the new era by all the three zodiacists. It is the Baiba Project that the world is shocked, the people are proud, and the people are waiting for.

Baifeng Beach is grand, ranking among the world’s top in its engineering scale, technical difficulty and industry position; Baifeng Beach is beautiful, and its beauty has gathered top technology and talents, gathered the wisdom and energy of the people, and will be prosperous. baby‘s grand and comprehensive benefits benefit people and social and national students.
The “Australia Secret Surface” of a major national weapon
The Jinsha River has abundant water resources, with a dodge of 11.24 billion kilowatts, ranking first among the “Thirteen Torrent Electric Bases” planned by our country. The Baidao Hydropower Station is located on the lower section of the Jinsha River in Ningnan County, Weishan Prefecture, Sichuan Province and Qiaojia County, Zhaotong City, Yunnan Province. It is a first-class hydropower station in the “Comprehensive Plan for the Changjiang River Basin (2012-2030 Escort manila” approved by the National Institute of Economic Affairs. Is it the third episode back? “The four hydro elevators in the lower reaches of the Jinsha River were developed and built by the group – the second elevator in Udongde, Baidao, Xiluodu and Xiangjiabao.
The right bank of Baiyang Hydropower Station belongs to Qiaojia County, Yunnan Province, and the left bank belongs to Ningnan County, Sichuan Province. It is the main component of the Changjiang flood control system. The engineering carriage is mainly composed of concrete double arches, flood discharge and energy-elimination buildings, and a shore water diversion and power generation system. The top height of the sank is 834 meters, the maximum height of the sank is 289 meters, the arc length in the middle of the sank is 709 meters, the normal water storage level is 825 meters, the total tank capacity of the sank is 20.627 billion cubic meters, the adjustable tank capacity is 10.436 billion cubic meters, and the flood control tank capacity is 7.5 billion cubic meters. 8 installed on the stationsThe platform has a 1 million kilowatt waterwheel generator set with a total capacity of 16 million kilowatts.
The Baikong Beach project began construction in 2012. It plans to complete the bottom liquidation and water storage before the end of April 2021. It will start to store water in May 2021. The first batch of machines will invest in power generation in the same year. All machines will be invested by the end of 2022. At that time, the Sanqi Group will set up the world’s largest cleaning power corridor on the Changjiang River.
The ten-year “family” project has been around the world
As the most torrent station under construction in the world, the important characteristic indicators of Baidao hydropower stations are among the forefront of the world’s hydropower projects, and the comprehensive technology level is the best in the history of the world’s engineering.
01
Single capacity 10Sugar daddy0,000 kilowatt ranks first in the world
One 1 million kilowatt waterwheel generator sets are installed on the shores. This is the first time that my country has adopted a national million kilowatt waterwheel generator set. It is the third country’s serious waterwheel installation equipment in my country. After the domestic industrialization of the Moon Machinery Group, another historic grand flight that has emerged on the basis of the domestic industrialization of Xiluodu and Xiangjiama Machinery Group will greatly promote the transformation from “Made in China” to “Creative in China”, and create a new world of hydroelectric million kilowatt water-wheel generator sets.
02
The round-cylinder tail water pressure well is the world’s largest scale
The design has 8 round-cylinder tail water pressure chambers with a straight height of 42-49 meters and a straight wall height of 77-92 meters. It is the largest tail water pressure chamber in the world’s hydroelectric projects.
03
The underground cave room group has the largest scale in the world
It has the largest underground cave room group in the worldSugar baby, the total length of the cave room is 217 kilometers. It is comparable to the distance between Shanghai and Ningbo. The excavation of the cave room is 25 million cubic meters, and the volume is sufficient to build ten Khufu pyramids. The underground factory has a length of 438 meters (the height of Shanghai Jinmao Building is 420.5 meters), a width above the tiles and a width below the tiles and 31 meters below the tiles and 86.7 meters high. It is the largest underground factory with the largest middle span of hydroelectric projects in the world, and it is also the country. href=”https://philippines-sugar.net/”>Escort The largest underground cavernous chamber group in internal and external hydropower projects.
04
The 300-meter-level high arch impeller seismic parameters rank first in the world
The Baidao Point Site District is located in the transition belt of two second-level structural units, namely two second-level structural units, namely the Kangdian axis and the Shangfengtai Pleeve Strap. It is located in the triangle area of Weishan. It is located on the east side of the structural belt and the Linfeng Peak – Qiaojia structure belt. The importance of geostrial danger comes from the impact of strong earthquakes outside, the scale of fractures in the area is generally small, the overall stability of the shell is better, and the greatest impact of historical geography on the Baidao Project Site is 8 degrees. According to the “Report on the Designed Metrology Parameters of Jinshajiang Baikong Hydropower Station Site Design” proposed in February 2016, the intensity of the geographic foundation of the site area was determined based on the geology parameter of 10% in the probability of exceeding 50 years, and finally it was determined to be 8 degrees.
05
300-meter-level high arch is used for the first time. The 300-meter-level high arch is a large area with a temperature control and crack-proof surface. The temperature control and crack-proof surface are extremely challenging during the construction period. For crack prevention problems of arch arch shaving, Baiba’s large shavings use low-heat cement concrete, with a total amount of low-heat cement concrete of 8.5 million cubic meters. This is the first international case and can ensure that there is no macroscopic cracking on the base of the shavings.
The uninhibited flood discharge cave group has the largest scale in the world
06
The Baiyang Project flood discharge building consists of 6 surface holes, 7 deep holes and 3 uninhibited direct flood discharge caves on the left bank. Under the verification of the working conditions, the total discharge of large water is about 42,000 cubic meters per second. The size of the single flood discharge hole is 15 meters wide and 18 meters high. The length of the three flood discharge holes is above 2,100 meters. The maximum total discharge volume is 12,250 cubic meters per second, accounting for about 30% of the total flood discharge volume.
07
The total capacity of the machine ranks second in the world
The Baiyang Electric Station has 8 platforms and 1 million kilowatt waterwheel generator sets are arranged on the shores of each station. The total capacity of the machine 16 million kilowatts is surpassed by Brazil’s Itap Hydropower Station and has become the world’s second torrent station after Sanshi Station.
08
The total water thrust of the arches ranks second in the world
The normal water storage level of the Baiba Bay is 825m. The total water thrust of the arches reaches 16.5 million tons, which is more than twice the total water thrust of the arches of the Udongde arches, and is only second to the small Bay High Arches.
