Zhang Sheng: "The Forbidden Area of Life" built a tank

Correspondent Peng Tsa

In the hinterland of Karakon Mountain, the natural environment here is so bad that ordinary people are unimaginable: atmospheric pressure and 59%of the sea level; the oxygen content in the air is half less than that of the plain, but ultraviolet radiation intensity is 50%higher than the average plain area; Snow, the so -called summer, the temperature is often below 0 degrees Celsius, the maximum temperature difference between day and night or even more than 30 degrees Celsius ...

Altitude 5,300 meters is an extreme environment in biology. However, a road -building iron army is active here. Zhang Sheng, the manager of the plateau highway project of China Railway 11th Bureau, led this road -building iron army to shout in the "restricted area of ​​life" and shouted "hardships are not afraid of suffering, hypoxia does not lack spirit, the storm is stronger, and the altitude is high." The slogan, use actual actions to practice the spirit of the Qinghai -Tibet railway and the "ascending spirit", build a sidelines to add color to the snowy plateau.

Courage to "climb high" and challenge the plateau

In October 2020, Zhang Sheng boarded the Cara -Kurunlon Mountains that were almost "ignorant" from the green and rainy rain and rain in the grass and trees, and bears the construction burden of the plateau highway project. The project department is located at the red willow beach at an altitude of 4200 meters.

Although psychologically prepared for hypoxia in the plateau, it was not expected that the plateau reaction was so powerful. "At that time, the whole person was stunned, and he felt a blank brain. I don't know what the sound buzzed by the ears." Zhang Sheng recalled the scene when he first arrived in the project, and he still had a lot of heart.

"For the first time as a project manager, it is the" leader "of the project, and it cannot be 'down' anyway. You must rush to the front and bring a good leader to the project employees and labor staff." Zhang Shengqiang endured extremely hypoxic hypoxia. The physical discomfort brings, the performance is like no one, with people who run the site, watch the site, watch the scene, and consider the supply of materials, formulate the construction organization plan for the drawing section of the drawing ... Li Yujie, the captain of the construction team, admire it very much.

In 2021, the project officially started construction. Zhang Sheng and Fu Fei, the secretary of the project party branch, discussed the establishment of a "leadership class" system in the project. Members of each project leadership team must live with employees at the front construction site.

Zhang Sheng took the lead in putting this system into action, and it was 7 months at a construction site at an altitude of more than 5,300 meters. Under the strong ultraviolet rays, the skin on his face and his neck was severely burned and began to peel, his lips were cracked and bleeding, and a dark face was nicknamed "Lao Tibetan" by everyone.

The plateau environment and construction fatigue, after returning to the station in the front, I just want to lie on the bed holding the oxygen cylinder for a while and more oxygen. Zhang Sheng watched his eyes and remembered in his heart. In addition to asking the cafeteria to make three meals a day, he also ran to the dormitory and asked them to get up for dinner. "Although I don't want to eat myself, I still endure some, not only responsible for my body, but also a role model for them." He said.

Do your best to ensure the construction

"Entering the plateau is both courage and belief, a dedication, but it is also a harvest." Zhang Sheng always used the words of the local people to motivate himself, carefully planned construction, crack the construction problem, do the project of the plateau highway, and win the reputation of the company.

"We must complete all construction tasks on August 30 according to the construction node issued by the owner. All employees must firmly anchor this goal and resolutely win this tackling battle." Since 2022 When the monthly conference and the control along the line, they always emphasize the project employees and the person in charge of the labor service.

Looking at the progress of the project steadily, Zhang Sheng was full of relief. Recalling the beginning of the project in 2020, because he couldn't find a suitable labor team, he was worried. "At that time, we were looking for the construction team everywhere. The company, the group company, and the construction units along the line recommended a lot of teams. Many construction leaders came to see the construction environment and turned away." Recalling the scene at that time, Zhang Sheng was still vividly visible to the eyes. "Even after the construction team, the operators came back and forth several times, because they couldn't adapt to the plateau environment." After the construction entered the track, Zhang Sheng was relieved.

"Compared with other bid sections, the company undertaken the line is the highest and most difficult section of altitude." In August 2021, the technicians returned from the construction site to the news: "The Daban section of the Daban section of 5630 meters above sea level, the excavation of earth and rocks is only every day. More than 1,000 square meters, the progress is very slow, it may be that I have encountered the frozen soil layer. "

"In the long run, you must delay the construction period!" In order to figure out the reason, Zhang Sheng took the technicians for 3 days in a row and walked 4 kilometers a day to check the construction line situation. After on -site analysis and repeated investigations, they determined that the section was a frozen -rich area for many years. "After making it clear, we discussed the meeting and replaced all the existing equipment with a high -power crushing hammer, which accelerated the construction progress."

He also organized the project to carry out a labor competition, and always completed the construction task according to the target of the node issued by the owner.

Exciting, "picking" benefits

"The construction site is located on the Karakon Plateau with an average altitude of 5,300 meters. The lack of labor resources, the transportation of material materials is very difficult, the technical personnel have insufficient management experience, and there is no mature experience within the company. Difficulties want to be in front, and "pick" benefits from it. In the early stage planning, Zhang Sheng led the project team to repeatedly investigate and compared the construction plan in detail to compile the preliminary planning of the "optimal" construction organization, and use this as an outline to guide the entire construction. "We conquered the seasonal settlement of the high -altitude frozen soil in the road base construction, and the cracks and thermal insulation problems in concrete construction due to the dry climate and the large temperature difference between the day and night, and avoiding the rework due to quality." Zhang Sheng introduced.

Zhang Sheng, who came from economic management, is very sensitive to cost management. At a time, on the basis of fully grasping the project design and budget of the project, he and the director of the project chief and planned department squatted at Urumqi to connect with the design institute to optimize the design drawings. Cage net protection, bridge budget, etc. are re -reviewed, reducing project costs.

Material equipment is the "big head" of engineering projects, and it is also an important sector that can ensure benefits. The project fully compares the two schemes of the dragon gates and crane beams. "The construction period of the beam farm is only one month. The Longmen crane is a special equipment. The equipment requires transportation, debugging and acceptance. Use at any time to enter the market, and the rental cost is still low. "Zhang Sheng said.

In addition, he also boldly proposed constructive opinions such as self -processing of geological materials, template allocation, and T -beam template on -site modification, and brought the role of "picking" to the extreme.

Watching the flat asphalt road winding forward between the mountains and mountains, Zhang Sheng said with emotion: "This road is like my child. After the entire line is opened to traffic, I must drive a circle and feel myself. The way to repair. "
