The surveying and mapping person on the plateau: sleeping in the sheep rim to fight the load on foot to overcome extreme weather

Recently, high temperatures in various places seem to be hot, and the sun is hot. On the Qinghai -Tibet Plateau, a group of people experience "two days of ice and fire" every day: a temperature difference of 20 degrees a day, and various weather in the rain and snow and frost, like speaking the concentrated year and four seasons. This is the daily work of a surveying and mapping team from Sichuan for nearly two months.

Li Wei, 32, is the Deputy Dean of the Sweet Institute of Navigation Institute of the Ministry of Natural Resources. It is the head of the mission area of ​​the Sichuan Bureau of Sichuan Bureau in the real 3D China Construction Sichuan Bureau in 2022. , Epidemic prevention, production and other work. On June 8 this year, he led the team to Qinghai Golmud to participate in the special project of the real 3D China construction project in 2022, and began a 60 -day surveying and mapping work. This work goal is to form a three -dimensional model of the Yangtze River and Yellow River Basin. In future protection work, it can provide corresponding technical support.

After a day, going through the "four seasons" extreme climate is the biggest test

Get up at 7 in the morning and eat, and go to the measurement location at 7:30. Under normal circumstances, it can not return to the station until seven or eight in the evening. After arriving at the station, the data measured on the day of the day should be sorted out, and the path and selection point that goes out the next day will not be able to sleep in a hurry until all jobs are completed at 12 am. From 7 am to 12 o'clock in the morning, day after day, such a dozen hours of work is his normal work. "It depends on the specific situation. Some places are really far away, and it is difficult to drive. It will continue until one or two in the morning."

"Ascending the spectacular world, the big river does not go back. Huang Yun moves the wind, and the white waves of Jiudao Liuxue Mountain." These verses are the vivid portrayal of Shi Xian Li Bai's style of Qinghai Mountain River. For surveying and mapping personnel, Qinghai, located on the Qinghai -Tibet Plateau, has a high -cold and dry climate condition, is a challenge to work.

Li Wei told reporters that in June, every day in the Guoluo test area, he experienced sudden changes in the weather. At the time of departure, the sun was still shining. When the operation of the measurement area was reached, it was pouring the rain and the temperature dropped by ten degrees. His jacket was soaked, and there was no place from head to toe. During the measurement point, the sun rose again, and the temperature rose to 20 degrees. However, when they completed the measurement and packed the instrument, it began to rain. Such a large temperature difference caused the team members to drag their tired body during the day and work outside.

Once, at the No. 218 of the Guoluo test district in Qinghai Province at 4,000 meters above sea level, the weather in the plateau desert changed, and the storm rain suddenly came 40 minutes before the measurement operation. His teammate Yao Yang, in order to ensure the smooth progress of the measurement task, got out of the car and helped the GPS receiver that was almost dumped in the wind, and persisted in the ice rain for 40 minutes. At the end of the observation, his clothes had a thick layer of ice crystal. Even if you get in the car with warm clothes, you cannot quickly alleviate the physiological reactions caused by severe temperature loss.

Under such climatic conditions, 9 players, including Li Wei, have worked on Qinghai for sixty days. In sixty days, they almost rotated in a few axis, there were no weekends in the middle, and there was no time to rest. "If you do not work continuously, you cannot guarantee the smooth progress of the project at all."

Sleeping the sheep ricers to defeat the high -anti -hiking load to the monitoring point

"We need to measure 440 points in total. Among them, there are twenty or thirty surveying and mapping points, and the vehicles cannot reach directly. "As a surveying person, Li Wei's instrument box and tripod added up to more than ten pounds. One day the measurement point of the homework was located at the desert.

On June 8th, the team operated to Qiuzhi Township, Qu Malai County, Yushu Prefecture, Qinghai Province. The local average local altitude was 4,000 meters. It is located in the hinterland of Sanjiangyuan Reserve. Temporary houses. They lived in the "sheep rim" -laid a temporary mattress, only one coal stove. Due to the plateau reaction, until four in the morning, the players were still sitting on the bed and looking at each other. Although the body was exhausted, headaches and dizziness made them unable to fall asleep all night. By seven in the morning, another new round of work was ushered in, and they continued to invest in their homework after eating breakfast.

Wu Dao Liangwu, Governor County, Yushu Prefecture, Qinghai Province, is located in the Qinghai -Tibet Plateau and the Western High Mountains in the Western Mountains called the "Forbidden Area of ​​Life". Due to the high altitude and terrain of 4675 meters, the air is not smooth, and the soil contains high mercury in this area and has a small vegetation, resulting in low oxygen content in the air. Generally, the altitude altitude reaction will appear here.

On June 15th, the project team operated to the most difficult area of the project. "After our measurement team reaches the five beams, some people have toothache and some people are swollen.When driving, even the elbows are swollen, just like gout. "When the operation reached the number 24, the altitude had climbed to 5 kilometers. Due to the melting of the sun and snow, the vehicle was trapped into the grass during driving.The team members endured the serious altitude response, and each took ten minutes for each iron shovel to carry out the rescue work.After nine hours of hard work, he finally returned to the station.At this time, the detection heart rate has shown that the team members have abnormal hearts.Even the computer using the observation data deforms because the air pressure is too high.Li Wei overcame the huge temperature difference and strong altitude reaction.This is a small microcosm of the surveying and mapping industry. Even if it is hard and tired, the surveying and mapping people have worked hard to practice "two branches and one improvement" with their own actual actions, and they traveled to China one by one.
