Baihe out of Sichuan, Jingshi played Kai

On August 13, the "Autumn Tiger" in Luzhou, Sichuan, has continued to 39 degrees Celsius since the day. Under the hot temperature, it has not relaxed the scene of the construction of the Longxu Railway and the Mianye high -speed rail construction line. The Line section of N4120 is the Baihetan -Zhejiang ± 800 kV DC transmission line project (Sichuan 6 standard section), which was constructed by the State Grid Hebei Beibei Beijing. The first stop of the hydropower high speed.

Baihetan-Zhejiang ± 800 kV high-voltage DC transmission project is a key demonstration project to implement the national "Western East Delivery" strategic deployment, build new power systems, and help achieve the "dual carbon" goal. It is of great significance to meet the "14th Five -Year Plan" power demand, service "dual carbon" goals, and local economic and social high -quality development.

As an important part of "White Crane out of Sichuan", building a boutique project has become the ultimate goal of the north. "The root of the root is not windy", a good project must start from the foundation. During the infrastructure stage, the construction project department of the Beijing delivery company has formulated a thorough construction plan for the first time. The cooperation ratio and pouring process are strictly controlled. The final 107 iron tower foundation was completed.

Among the total length of the White Zhejiang Project (Sichuan Section), the 25.012 kilometers of the lines are on both sides of the 25.012 kilometers. It is a huge test. "Construction in this environment, it can't be slow! It can only be planned and successful." Fang Quan, the project manager, said, "In order to ensure the safety of construction and on -site personnel, we have organized experts many times to hold a demonstration meeting to carry out anti -induction prevention induction. Electricity research has formed a set of effective technical measures for anti -sensing electrical electrical electricals. " "Equipment and so on." On May 21, 2022, after 87 days of fighting, the construction of the tower of the packet section was successfully completed; on July 2, 2022, it took 53 days, and the most densely schedules of the packet section spanned the construction smoothly.

After the brief joy, the last two line sections followed the double railway (Longxu Railway and Mianlong High Speed ​​Rail) and Shuang Expressway (Xiarong Expressway and Rongzun Highway). While the construction of the high -speed rail at night brought on -site safety management pressure, since July, Sichuan has encountered extreme high -temperature weather for 60 years. The psychology and body of the construction staff have been challenged. "The window period across the high -speed and railway is planned in advance with the relevant operation and maintenance units. How to manage the scene while taking care of the comrades' bodies is what the project department has been doing." Wei Guangchuan, the director of security. "The construction of the peak, 1500 bottle of Huoxiangzhengqi liquid per week, the mung bean soup daily, the watermelon twice a week, etc. These are directly sent to every construction person at the scene. Strong, you can implement the safety. "

Double high -speed spanning at the same time is a major difficulty in the 15 spans of the project. Time, large span, complex terrain and other problems, which make the net time planned for 8 hours. In order to reduce the risk of construction, the project department, highway management company and traffic police department have conducted multiple coordination, and held a special meeting to discuss the road closure plan. "The highway has been closed and the Internet has begun." At 12:30 noon on July 25th, with the road closure instructions of Feng Xu, the deputy manager of the project, in 10 minutes, two giant nets with a length of 44 meters long and 12 meters wide were covered over the above place. The network work was successfully completed, and Xiarong's high -speed high -speed recovery was resumed. "Don't look at the final net sealing only 10 minutes. The early sealing construction plan was made more than ten surveys at the scene." Li Li, chief of the project, said, "To maximize the construction of construction to high -speed high -speed high -speed high -speed speed The influence, finally decided to adopt a false burden on one side, and the on -site method of leaping on the ground, greatly using the terrain, simplifying the preparations of the early stage, and reducing the operation time. "

Mianye high-speed rail sealing network and leap-out are the end of the project. At 0:00 in the morning, the daylight point test testing the project department organization and management capabilities. The planning task within the specified time is to confirm that every manager in front of the sunroof point is annoying. 8 groups of lamps, 70 headlights, 30 flashlights, 6 -sealing system bearing rope, 6 network rope, 40 mesh rope, 20 glass renewal rods, 24 pulleys, 24 hand tie gourds, 2 The drone, the 800 -meter guide rope, the two walking boards, the seat belt, the helmet, the climbing rope and other equipment and protective supplies and protective supplies need to be confirmed one by one in front of the sunroof point. "It is necessary to put the equipment fixed in advance at the designated position, otherwise it is temporarily looking for it. It delays the normal operation of the high -speed rail.

"The Mianye high -speed rail has been blocked, the electricity check -up is completed, and it can be constructed." At 0:10 am on August 8th, with the project manager Fang Quan received the construction instructions to allow the high -speed railway and the maintenance area, the construction order was issued to all management and construction staff. The two drones took off at the same time, and the signs were endless. "The drone on the left has taken off, and there are 80 meters away from the large side of the large side." Looking at the scene, the visiting lights shine on the construction site. The drone slowly moved forward with the guide rope. Working together in the post, the safety monitor and inspector are staring at each operation link ... Everyone was not moved by 35 degrees of high temperature that night. After 90 minutes, the high -speed rail sealing network was successfully completed, and the huge grid system made of steel pipes flashed under the lighting of the lighting light. The leap rack on both sides of the railway supported the safety protection net above. The train has set up a safe "corridor", and it also provides a strong security guarantee for the line construction of the subsequent sunroof point. "Baby, Dad, after a few days after the project acceptance, I went back." The fluent "Trump" of the construction squad leader echoed in the sunset. Luo Zhengquan has his own arrangements for the short holiday after the project. "It happened a few days later the child's birthday. Our project will also be completed smoothly. Shuangxi Linmen is worth celebrating. A few days ago, I bought toys for the child in the town and prepared to take him home to surprise him." There are more than 500 Sichuan workers such as Luo Zhengquan in the Sichuan 6th standard section. "Zhao Tianhua, the construction squad leader of the same family in Sichuan, said with emotion.

It is expected that at the end of this year, after the entire project runs through, the annual power delivery volume is expected to exceed 23.6 billion kWh, which is equivalent to reducing the consumption of 10.57 million tons of coal combustion and 19.19 million tons of carbon emissions. This beautiful "white crane" entered Zhejiang from Sichuan, and continued to clean the power to East China. (Li Yan)
