39 years ago today, on November 19, 1986 (October 18, 1986 lunar calendar), a large hydropower station was built on the Nanpanjiang River. At 11:45 on November 19, 1986, a 32-ton large dump truck dumped the last truck of boulders into the heart of the river Longkou, and the wild Nanpanjiang was finally cut off. One of the largest hydropower stations currently under construction in our country, Tianshengqiao Secondary Power Station, was successfully intercepted. The closure of the first hub of Tianshengqiao Phase II Hydropower Station began at 9:30. 70 large dump trucks dumped a truck at a speed of 30 seconds, throwing a truck of concrete tetrahedrons, stone strings, boulders and stone slag towards Longkou, the heart of the river. After 2 hours and 15 minutes of fierce fighting, a total of more than 1,500 cubic meters were thrown, and Longkou was finally blocked. Premier Zhao Ziyang and Vice Premier Li Peng came to the scene to watch the spectacular scene of the closure and extended cordial greetings and congratulations to the commanders and fighters of the Armed Police Hydropower Corps who were responsible for the construction task. Tianshengqiao Hydropower Station is located on the Nanpanjiang River at the junction of Qiangui and Guangxi provinces. It is a key national construction project. It consists of two-stage hydropower stations constructed in stages and continuously constructed, with a total installed capacity of 2.52 million kilowatts and an average annual power generation of 13.40 billion 45 million degrees. After the completion of the power station, it will effectively improve the power supply quality of South China and Southwest China Power Grid and improve the efficiency of the power grid. It has important strategic significance for the west-east power transfer of South China Power Grid, easing the pressure on Guangdong power supply, and promoting the economic revitalization of Guangdong, Guangdong and Guizhou.
