Beijing, 20 Jan (China Youth Network) -- On 20 January, reporter Zhu Haotian, correspondent Guan Hehe, and Li Jichun saw that the north wind was whistling on the ninth cold day. On January 17, the first day of the Spring Festival, the bridge and tunnel workers of the Changchun Engineering Section of China Railway Shenyang Bureau Group Co., Ltd. went out early and began the bridge maintenance work.
The bridge to be repaired that day is located on the throat of the Beijing-Harbin line, the railway people call it the Songhua River Railway Bridge, in order to ensure the absolute safety of the bridge during the Spring Festival, they set off from Changchun at three o'clock in the morning and began the inspection and maintenance of this bridge during the Spring Festival.

"Frost returns on the river, everyone must not step on the rails, pay attention to the feet, prevent slippage, pay attention to personal safety." Zang Hongjin, the head of the bridge and tunnel work area of the inspection workshop responsible for this operation, instructed the operators to walk forward cautiously. Before dawn, the downward blockade of the skylight order was issued, and the operators took flashlights and began to inspect the operation on the bridge.
Songhua River railway bridge deck is nearly 20 meters away from the river surface, people walk on it to make a "banging" sound, looking down at the ice surface, it will feel a little floating, and Zang Hongjin said: "Before I was also afraid, the number of times I came, I didn't have time to take care of the height, the inspection operation was more nervous, more cumbersome, and slowly I got used to this kind of high-altitude work." ”
"The 96th anti-climbing angle steel bolt of the 96th sleeper on the right side of the 18th hole of the bridge deck sleeper is loose." Hearing the squad leader Zang Hongjin inspect the disease shouted out, Zu Longhua, a bridge and tunnel worker, took out a record book and carefully remembered it.
Operators should first inspect the upper span of the Songhua River Bridge and the line rails and fixed bolts, while paying attention to the road conditions under their feet, while looking up to check the upper span steel beams. "The cold on the bridge is not the same as the cold below, the cold wind drills into the arms, and the cold on the ice feels like it can drill into the cracks of the bones, and it is useless to wear as much." The temperature in Dehui City is minus 25 degrees Celsius, but it can reach minus 30 degrees Celsius on the bridge. Zang Hongjin stomped his feet and said. After a while, the bridge and tunnel workers' cotton hats and masks were covered with frost.

"The bolt above the third vertical rod on the left side of the twelfth hole was confirmed with a telescope, and it looked as if it was broken." After the experienced bridge and tunnel worker Yan Baoheng visually detected the disease, Zang Hongjin picked up a telescope to confirm the disease, recorded it in a book, and marked it with a key mark.

After inspecting the upper span of the bridge, they also have to check the connection between the pier and the main body of the bridge, at this time they have to go down to the bridge pier, the working space at the pier is small, the operator can only half squat or half kneel for inspection, nestled on each bolt or naked eye observation or with the inspection hammer to check, they completely disregard the coolness from the knee, continue this posture until the inspection is completed. When I reached the exit, I stretched my waist and legs, which were already numb.

Songhua River Bridge has a total of 28 piers, bridge and tunnel workers are fully focused on one by one inspection, on the bridge deck, down the pier platform, each time a disease is detected, it will be carefully recorded, and then notify the bridge tunnel workshop for disease treatment after the end of the skylight operation time.

After four hours of operation, the inspection of the Songhua River Bridge was successfully completed. During the Spring Festival, these bridge and tunnel workers will guard the throat of the Beijing-Harbin Railway, and at an altitude of tens of meters, they will become "high-altitude dancers" who guard safety and guard the safety and smoothness of the road home for thousands of passengers.
