"Let's go! Let's hurry. The hour hand was close to 0:00 on January 31, and Zhao Haichun, 54 years old this year, waved his hand and led more than 20 young men into the cold night. At this time, the temperature has dropped below freezing, and everyone unconsciously tightens their collars.
Here, it is the downward yard of Shuangqiao Station of the Beijing-Harbin Railway Line. Starting at 0:30 a.m., during the tense 75-minute "skylight point" (a period when no train passes), linemen will race against time to complete the maintenance task. "Entering the Spring Festival, the car is dense, and the wear and tear on the rails is greater, so we can only see the stitches and send more manpower. "Zhao Haichun is burly, striding meteor, not talking much, and every sentence can't be avoided professionally.
1 rail grinding machine, 3 sledgehammers, 1 electric welding machine......By the searchlight not far away, everyone lined up and listened to the team count the tools. "How to bring the line, how to bring it out, not a single screw can be dropped to ensure the safety of the line. Zhao Haichun was meticulous and ready to go. In addition to the walkie-talkie pinned to his shoulder, the flashlight on his waist, and his backpack also contained a record book, a feeler gauge, and a small mirror, all of which were his diagnostic treasures.
Confirm that you don't have a car and are ready to go on the road. At 0:30 sharp, Zhao Haichun gave an order, and the linemen rushed to their respective renovation points according to the division of labor. On the dark track line, the reporter staggered, but Zhao Haichun had wind on the soles of his feet. Entering his "home field", this silent lineman actually talked a lot.
Squatting on the side of the track, Zhao Haichun put a one-meter-long steel ruler on the track, and then used a small feeler gauge to measure the gap between the steel ruler and the track. "Now you can intuitively see that the joint gap is 1 mm, and for a line with a speed of 120 kilometers per hour, this value should be controlled at 03 mm or less. Otherwise, the track surface is not smooth, and the train will be bumpy as it passes. Zhao Haichun said while helping the lineman to put more than 100 kilograms of rail grinder on the track.
Along the direction of the track, Zhao Haichun pushed and pulled the grinder back and forth, with the roar of the machine in his ears and the sparks splashing in front of him, as if he was "playing iron flowers" on the railway line. Rail grinding is a delicate job, not only to master the strength, but also to practice good eyesight.
If you look at this section of the rail, the sparks on both sides are large when grinding, and the sparks in the middle are small, indicating that the two sides are still high and need to be smoothed. ”Zhao Haichun's eyes are like a ruler, able to accurately judge the "heat" of polishing. "It's pretty much the same time. After pushing and pulling and grinding hundreds of times, Zhao Haichun stopped, took off his gloves, and slid his fingertips over the rails to feel the state of the rails after grinding. Leaned over to retest, and sure enough, the gap was lower than 03 mm.
After polishing here, Zhao Haichun walked hundreds of meters and rushed to the turnout maintenance site for inspection. "This wing rail has been crushed before, like a sore, and it will continue to fester. Zhao Haichun stroked the restored steel rail, and said with satisfaction that after timely "scraping the bones to cure the poison", the disease has been removed, and the life of the track can be extended.
For linemen, winter is the most fearful of snow. In order to avoid ice formation on the turnouts, they need to clear the snow from the turnouts despite heavy snowfall. "The coat freezes the ice, and the inside is sweaty, and it doesn't taste good. Zhao Haichun sighed that compared with the past, now at least there is no need to rely on people to carry equipment and walk several kilometers on foot.
Beijing Public Works Section Shuangqiao Line Workshop, under the jurisdiction of Beijing-Harbin Line, Beijing-Chengcheng Line and Fengshuang Line and other important lines, is responsible for the maintenance of 177 kilometers of lines and 310 groups of turnouts, not only on the line, trucks mixed running, there is also a marshalling yard, can be said to be one of the busiest line workshops.
The workshop is only 100 meters away from Zhao Haichun's home, but he rarely goes home during the Spring Festival, and everyone says that he "grows" in the workshop.
Just like today, after doing these 75 minutes, I have to take a breath in the middle, and I have to rush to Shuangqiao Station at 4 o'clock in the morning to continue maintenance. Going home at night is also a disturbance to the rest of the family. During the day, there are problems that need to be dealt with at any time. As the director of the workshop, Zhao Haichun is responsible for the four work areas and is ready to deal with sudden failures at any time.
In the 38 years since he entered the industry, Zhao Haichun has lost count of how many Spring Festival holidays have been spent on the steel rails and in the sound of grinding. He has ensured the safe arrival of countless trains, but he rarely travels by train. I take the train 4 times a month, still to find out the problem of the steel rails behind the shaking and bumping of the train from the perspective of passengers.
When I was young, I felt very bored and lonely to be with the rails every day. After doing it for so many years, I have feelings. Leaving the rails, I always feel that there is something short. Zhao Haichun, who has retired in 4 years, has begun to give up.
