Nuozha Wake Water Station is located in Pu’er City, Yunnan Province. It is the fifth in the “Two and Eighth Levels” plan for the middle and lower river sections of the Lunjiang River. The total capacity of the water tank is 23.703 billion cubic meters, which is equivalent to the water storage capacity of 16 Kunming Dianchi Lakes. The power station has a large 261.5-meter-high heart-stacked stone crust, which is the highest and third highest earth-stacked stone crust in the world. It is the most representative international milestone project of the high-stacked stone crust in the world.
As a country, implement “Sugar babyXiyundong Send”, one of the serious strategic projects of “cloud-electricity delivery”, Nuozhadu Electric Station has a total investment of 61 billion yuan, and a total of 9 single machines and 650,000 kilowatt machines have been installed. The power station guarantees a 2.406 million kilowatt output, and has an average power generation of 2.3912 billion kilowatts over the years. As the national festival is about 9.56 million yuan, it reduces carbon dioxide by 18.77 million tons, and has mainly contributed to the good and rapid development of Yunnan Province’s economic and social development in the country.
The China Electric Power Construction Group has participated in the construction and construction of Nuozhadu Electric Station.
Kunming Survey Institute undertakes the design tasks of the power station; the 14th Hydropower Bureau undertakes the power station flow, flood discharge, slope excavation and water diversion power generation system, three-stage power generation unit and public servicePinay The contract amount of all the motor and electrical equipment installation construction of the escort system is approximately RMB 3.5 billion; the Eighth Bureau of Water and Electricity undertakes the installation task of 6 machines; the Seventh Bureau of Water and Electricity undertakes the construction of spillway engineering and the production and operation of sand and gravel system; the Third Bureau of Water and Electricity undertakes the construction of the on-site highway engineering.
The construction of Nuozha Water-Waiting Power Station has developed the “digital magnitude” system for the first time, which has effectively solved the most important technical difficulties in determining the safety of high earth and stone magnitudes, and has ensured the construction quality of the total area of more than 34 million square meters, becoming a serious innovation in the world’s large magnitude construction quality control technology. The system proposed a complete set of technology of “high-heart wall pile stone pile using artificial gravel and soil slurry” and “Sugar baby‘s babyThe new structure of the base plate of the pond guardrail border” has been developed and built a “new type of water inlet for beam doors in layers”… A series of serious Ye Qiuguans were invited by friends to participate in the knowledge competition program. During the recording process, scientific and technological innovation has been achieved, which has reduced the power supply. The construction difficulty of the station significantly saves project investment, ensures safety of project construction, realizes the complementary between hydroelectric development and ecological environment protection, and has also seriously affected the flood control and drought resistance of countries under the river of the Yangtze River, and has achieved the cooperation and wins together among high and low countries.
The construction and construction of Nuozha Water-Waiting Electric Station has successively won 6 national science and technology progress awards and 21 provincial and ministerial first-class and above science and technology progress awards. Among them, “Super high-core stone-stacking key technology and application”, “Serious water conservancy and hydroelectric engineering construction key technology and its engineering application”, “Visible simulation technology and its engineering application of major water conservancy and hydroelectric engineering” won the second-class national science and technology progress award; “Research and application of key technology for Nuozha water-wading power station guide and intercepting engineering”, “Major type”The theoretical research and engineering of the hydraulic and electric station pressure pipeline and shell structure” has been awarded the first-class award for provincial and ministerial scientific and technological progress.
Technology first strengthens the tendons and bones
Nuozha Water Wake Station No. 1 and 2, the left bank flood discharge hole and the underground water diversion power generation system project undertaken by the 14th Bureau of the Water and Electricity BureauEscort Manila and motor equipment installation construction are facing many cutting-edge technical problems of the Manila escort project, which is extremely challenging. In March 2006, the flow tunnels of No. 1 and No. 2 were dug into the Cenli period. In the ground, a large and poor geological barrier barrier blocked construction above the tunnel, which is the F3 geological barrier. Its important structure is sand that is known as “the engineer’s disaster”. Manila escort is slim and loses down with one hand; a little vibration makes the entire palm sink and landslides can occur at any time! Project chief Ling Zhenghua and Zhang Chunhong, director of the Technology Department, lead a technical staff member, Chen Jubai. escort does not quite meet Song Wei’s standards. , check the local quality of the layer during the day, analyze the analysis of the compound exploration and experiment, and discuss the technical plan based on data discussion and research, and work overtime in the morning to stay up late to prepare technical methods. Borrowing the rich construction experience of the “underground iron army” of the 14th Bureau of Water and Electricity, we will follow the “three super” principles of advanced detection, advanced drainage and advanced support. Manila, control ruler, control seal, control measurement “three controls” method is stable and stable, and they finally crossed the F3 thrust layer safely. In June 2008, the construction of the underground main and auxiliary factories of the station, which are 418 meters long, 28 meters wide and 81.6 meters high, is in full swing. The grand sound of the hole-making machine is in full swing. As the factory has been resounding, people can only communicate with each other head-on and shout at the top of their voices. The main factory has a bearing capacity of 1,700 tons, and the length of the high and low side arch beams is 396 meters. Many indicators are in the leading position in China. In order to ensure its excavation quality, before building the hole, the first part of the measuring staff strictly according to the design and release the wiring; href=”https://philippines-sugar.net/”>Sugar daddyWhen the hole is holed, the steel tube is used to fix the hole, and the wall probe is explored. After the hole is made, the experienced blasters are vigilant to install the medicine; after the blasting, the engineering and technical personnel exchanged the “pull” and “clinic” on the scene… It is precisely this kind of “flower on the rocks
