Construction of central Yunnan Diaration Project Accelerated Promotion

At present, the construction of the Chu Xiong Guanyin Mountain Pressure Steel Pipe in Central Yunnan Diaration Project has been promoted smoothly. Guanyin Mountain pressure steel pipe inverted siphon project is located in Bicheng Town, Lufeng County. The total length is 9.777 kilometers. The design uses 3 inner diameter of 4.2 meters of pressure steel pipes, and the design flow is 100 cubic meters per second.

The first special tunnel of the Kunming section of the Sanqing Expressway runs through

Recently, the old Hei Mountain Tunnel of the Sanqing Expressway has achieved dual -line penetration. This is the first special tunnel of the Kunming section of the Sanqing Expressway.

The Laoheishan Tunnel is a left and right separation tunnel. The left line is 3606 meters long and the right line is 3633 meters long. The inlet and export of the tunnel is located in the mountains and valleys. The geological structure is complex and large reservoirs are penetrated. During the construction process, there must be three fault belts. The construction difficulty is large, interference, and high risk. The project department adopts advanced geological forecast and introduces intelligent workflows such as digital safety management control systems and concrete pouring arched air off -air device. While ensuring the safety and quality of the project, it improves construction efficiency.

According to the relevant person in charge of the Sanqing Project of China Railway 25, a reservoir with a reservoir of 120,000 cubic meters above the left hole of the Laoshan Tunnel is the biggest source of risk of the entire tunnel. To this end, the builders strengthen the stability of the surrounding rock by strengthening the stability of the surrounding rock by reinforcing the rocks in front of the palm.

The Sanqing Expressway starts from Qujing Sanbao and ends in Kunming's water. The route is 128 kilometers in length. It is designed according to the two -way six -lane lane. The design speed is 100 kilometers per hour. After the entire online opening, the province will add another important passage, and the driving time from Qujing to Kunming will be shortened by 40 minutes.

Wangjiazhai Tunnel in Linqing Highway exceeds 80%

The reporter recently learned from the Yunnan Communications Group that Wangjiazhai's special tunnel in the Linqing Highway Project exceeded 80%.

The Wangjiazhai Special Tunnel is the longest tunnel and key control projects across the board. It has a total length of 8040 meters and a total length of 8010 meters. The maximum burial depth is about 1022 meters. The geological conditions of the Linxiang section of the tunnel are complicated and the construction technology is difficult. As of now, the Wangjiazhai Special Tunnel has a total of 6412.4 meters from left, and the cumulative tunnel is 6585.3 meters on the right. It is expected to achieve double -amplitude in 2023.

The total length of the Linqing Expressway is 156.482 kilometers, starting from Jiuzhai Village, Lincun City, and ends at the Kuanshui River port of China -Myanmar border. After the entire line is opened to traffic, the driving time from Linxiang District, Lincang City to Qingshui River port will be shortened from the original 5 hours to about 1.5 hours.

The 11th unit of the Baihetan Hydropower Station is put into production

On September 18th, Unit 13 (Yunnan side) of Baihetan Hydropower Station successfully passed the 72 -hour trial operation and officially put into commercial operation. This is the 11th million -kilowatt water rotor generator crew put into power in the Baihetan Hydropower Station, and it is also the 105th water wheel generator crew built on the dry flow of the Three Gorges Group on the dry flow of the Yangtze River.

The Baihetan Hydropower Station is located on the downstream dry flow section of the Jinsha River at the junction of Qiaojia County, Yunnan Province and Ningnan County, Sichuan Province. It is the largest and most technological hydropower project in the world today. Rotation generator set.

After the completion of the Baihetan Hydropower Station, it will become the world's second largest hydropower station second only to the Three Gorges Power Station. The average annual average power generation can reach 62.443 billion kilowatt -hours. At that time, the world's largest clean energy corridor consisting of Wu Dongde, Baihe Beach, Xiluo, Xiangjiaba, Three Gorges, and Gezhouba -level stalls will be fully completed. The total installed capacity will reach 71.695 million kilowatts.
