On September 23, with the breakout of the construction robotic arm, the first tunnel of the tunnel Xiaoshan Tunnel in Yunnan Province in Yunnan Province, the Chongqing high -speed railway, was successfully connected, marking a phased progress in the construction of the Yukun high -speed rail Yungui section.

Koyama Tunnel is located in Huizawa County, Qujing City to make up for the town. The total length of the tunnel is 257 meters. It is a single hole and double -line tunnel with a maximum buried depth of about 18.5 meters. Poor, there is a risk of shallow burial partial landslides and dangerous rocks. The tunnel cave is set up for 30 meters long and bright caves. After two entrances and two holes, the construction process is complicated.

Zhaotong Tunnel No. 1 is smoothly excavated to the bottom of the well

On September 19th, the No. 1 slope of the Zhaotong Tunnel of the Chongqing -Kunming High -speed Railway was successfully constructed to the bottom of the well, and then transferred to the top of the main hole to laid a solid foundation for the early realization of the whole tunnel.

The Chongqing high -speed rail is an important part of the "Beijing -Kunming Channel" one of the main channels of the "Eight Eights and Eight Heng" high -speed railway in China. Southern Station, 699 kilometers in length, planned a total of 21 stations, and the target value of passenger trains is 350 kilometers per hour.

After the Chongqing high -speed rail is completed and opened to traffic, it will further improve the national comprehensive three -dimensional transportation network, strengthen the Unicom between the Shuangcheng Economic Circle and the urban agglomeration of Central Yunnan in the Chengyu area, greatly reduce the railway travel time from Chongqing to Kunming, which greatly improves the travel of the people along the route. Conditions to promote high -quality economic and social development in the region along the route.

Baihetan Hydropower Station left bank unit

All put into production

On September 22, Unit 8 Baihetan Hydropower Station successfully passed the grid -to -network debugging for 72 hours of trial operation, and officially transferred to commercial operation, marking that the left bank of the Baihetan Hydropower Station was put into production and power generation.

The Baihetan Hydropower Station is equipped with a total of 16 single -machine capacity of 1 million kilowatts of water wheel generator sets. Among them, units 1 to 8 are arranged in the left bank plant, and units 9 to 16 are arranged in the right bank plant. The No. 8 unit of this production is the 12th million -kilowatt water wheel generator set in the Baihetan Hydropower Station.

As of now, Baihetan has been put into production in a safe and stable operating state. The cumulative power generation has exceeded 41 billion kilowatt -hours, which has effectively guaranteed the safe and stable supply of electricity.

The left amplitude of the Yiwu Tunnel runs through

On September 16th, the left -handed leisure of the Miyu Highway I could.

The Yiwu Tunnel is located in Yiwu Town, Mengla County, Xishuangbanna Prefecture. It belongs to the special tunnel and is one of the controlling projects of the Green Highway. The left line of the tunnel is 3609 meters in length and the maximum buried depth is 343.38 meters. The tunnel area is in the rock structure and erosion of the low Zhongshan landform area. The stratigraphic rocks are mainly powder clay, weathered mudstone, sandstone, thin-middle-like structure, fissure development, and strong rock body rich water.

Ruimeng High Speed ​​Snow Forest Liangzi Tunnel

Dual -intensive

Recently, the Ruili -Menglian Expressway Snowfill Liangzi Tunnel has successfully penetrated the right side. At this point, the Cedar Liangzi Tunnel has achieved dual -amplitude. This is the first double -run tunnel in the Lancang Lauli Autonomous County of the Ruimeng Expressway.

Gaoligong Mountain Tunnel of Darui Railway

Near half

In Longling County, more than 110 kilometers away from Baoshan City, the construction of the first super project throughout the Hengduan Mountains -the Gaoligong Mountain Tunnel of the Darui Railway is underway.

As of September 14, the front -cave tunnel of the Gaoligongshan Tunnel completed 16.87 kilometers, accounting for 48.9%of the total length, and the remaining 17.66 kilometers; the flat guide completed 17 kilometers, accounting for 49.3%of the total length, and the remaining 17.49 kilometers.

Yongda High Speed ​​Jiangdi River Bridge

The construction progress is happy

Recently, the latest news came from the construction site of the Jiangdi River Bridge of Yongren to the Dayao Expressway: The steel box beams in the 77 sections of the bridge have set up 32 sections to complete the 41.5%of all sections of installation tasks.

The Jiangdi River Bridge is located at the junction of Yongren County and Dayao County of Chuxiong and Yi Autonomous Prefecture.

Central Yunnan Water Dreatment Project

Chuxiong section 3 standard barrier line line

Fengtun Tunnel 2#Construction branch hole

To the export of Fengtun Tunnel, the exit

On September 22, the exit of the exit of the exit of the Chu Xiong section 3 -standard Guanba Tower of the Chuxiong Section of the Chuxiong Section of the Central Yunnan Diaration Project smoothly opened up the exit from the construction branch hole to the Fengtun Tunnel, which laid a solid foundation for the safety completion of the longest cave digging tasks of the entire section of the entire section.

As of now, the main hole of the Fengtun Tunnel has completed a total of 5695.18 meters and the remaining 4166.98 meters. It is the longest -notch section of the Chuxiong section. The smooth penetration of the exit of Fengtun Tunnel 2#Construction branch and the exit of Fengtun Tunnel will greatly reduce the security risks in the subsequent excavation process, greatly increase the speed of excavation of upstream excavation, and lay a solid foundation for the early penetration of the Fengtun Tunnel.
