Changchun, February 8 (Reporter Shu Zhen, correspondent Li Dong, Guo Lei, Wang Qiang, Teng Dawei) In February, the Changbai Mountains were covered with snow, and the Meiji Railway Line, located in the hinterland of the Changbai Mountains of Jilin Province, was like a giant dragon winding through it, with thick snow covering both sides of the railway line.

At 6:30 on the 5th, the sky had not yet dawned, and Gong Weihui had already embarked on the road to the unit. In the severe cold of minus 30 degrees, he came to the unit in advance and carefully checked the flaw detector, just to save the workers half an hour of machine preparation time.
As the foreman of the Tonghua flaw detection work area of the first general chemical section of China Railway Shenyang Bureau Group, Gong Weihui took the initiative to ask for help during the Spring Festival and led a commando team composed of 7 party members to carry out encrypted flaw detection in the most difficult section of the Meiji railway line.

It is understood that the Meiji railway line is an important channel for grain and coal transportation in Northeast China, and a large number of passengers and materials are transported to all parts of the country through this railway line every winter. However, due to the large number of small radius curves, the large number of rail welds, and the erosion of severe cold, the rail flaw detection work becomes extremely difficult.
The flaw detectors are vividly known as "rail doctors". Their task was to carry out a "B-ultrasound" inspection of the two rails under the wheels. The ultrasonic flaw detector is used to detect the inside of the rail, and at the same time, it is also necessary to check the outside of the rail by manual methods such as small mirrors and small hammers, so as to find the damage of the rail in time.

At 7:30, Gong Weihui and the workers finished the pre-shift meeting and took the engineering vehicle to the 93 kilometers of the Meiji line. They need to carry more than 40 pounds of instruments and go down to the snow slope of more than 30 degrees to reach the work position. After arriving, after confirming that there were no cars in the section, they began the flaw detection operation. The ticking sound of two ultrasonic flaw detectors moving slowly on the rails and the crisp sound of the flaw detection hammer hitting the rails echoed in the valley, forming a unique "music". The trick of flaw detection is to judge whether the rail is damaged from this "music".
Flaw detection may seem easy, but it is actually extremely technical. Cracks, fish scales, abrasions, ......These damages are only a few millimeters on the rails, and even more so on the instrument waveform, so they must be seen slowly and carefully, without being sloppy in the slightest. Cheng Hongtao, the leader of the flaw detection team, said with a smile: "We walk seven or eight kilometers a day, with an average of about 20,000 steps a day, and the number of steps can occupy the top of the WeChat movement list for a long time." ”
The staff walked slowly and looked carefully, and they could not be sloppy at all (contributed by the Chemical Affairs Section of the Shenyang Bureau of China Railway).
In order to ensure the accuracy of the inspection, every inch of rail must be checked in place, each rail joint must be checked at least twice, and the data must be transmitted to the "playback group" for secondary data inspection in time. When they encounter abnormal waveforms during the operation, they squat next to the rails, pick up the snowdrifts with their hands, and use a small mirror to check whether there are any scars on the jaws or bottom of the rails. If they couldn't see clearly in the small mirror, they lay on the cold sleepers, their heads pressed against the rails, looked carefully with their eyes, and carefully checked with small instruments.
On a winter day, a green train sped by, temporarily interrupting their work. The snow particles rolled up by the train hit the frozen red faces of the flaw detectors, and vaguely, the passengers in the carriage could be seen waving to them standing outside for the New Year. This scene made their hearts well.

The passengers who come and go during the Spring Festival and the coal and grain we have here are all transported out from this line, and our work can only be meticulous and meticulous in order to escort this important railway transportation line. Gong Weihui and his workers are like plum blossoms in winter, defying the cold and sticking to their posts to escort the safety of railway transportation.
