At the age of 23, Zhang Beiyu, who loves swimming, went through many promotions and specialized research and training, and became a railway officer as he wished. The “frogman” realized his long-awaited “superhero dream” of protecting the underwater safety of bridges.
With the development of my country’s bridge construction work, various bridges have been built across rivers, lakes and seas all over the country, and a special team came into being. They are an underwater scout, responsible for conducting underwater “physical examinations” for the bridge. They are Jamaica Sugar Daddy, a bridge underwater inspection team at the railway readiness ship bridge. The average age of the 13 team members is only 28 years old. In 2021, Zhang Beiyu became one of them.
Becoming a qualified railway “frogman” requires a lot of hard work – for this, Zhang Beiyu is fully prepared.
The tasks of railway divers include emergency support, underwater inspection of bridges, diving salvage, underwater welding and cutting of bridges, etc. They need to obtain a standard certificate after a variety of specialized studies and training before they can start underwater operations. To this end, the practical courses they need to pass include flowJM Escorts mechanics, river bed knowledge, bridge pier structure and data processing analysis, practical operation courses Including the ability to use equipment, underwater exploration, underwater welding, and independently respond to various emergencies.
The railway “frogman” reaches the working waters through the hanging cage and is about to explore the underwater surroundings for the bridge under construction.
Before each dive, railway divers need to wear 36 kilograms of counterweight, put on 17 kilograms of lead shoes, and add Put on a helmet, dry clothes, and a gas bottle. The complete set of equipment weighs hundreds of pounds. On average, 2 underwater explorations are performed each time.For more than 1 hour, for the safety of the bridge, water must be launched even in winter.
On his first mission, Zhang Beiyu asked his colleagues to help him shoot a cross-dressing video as a souvenir before the mission started. In the video, the contrast between before and after the disguise and the special effects music combine to instantly transform Zhang Beiyu into a railway “frogman”. After the work was completed, Zhang Beiyu specially forwarded the video work to his parents to share with them the joy of realizing his dream.
“I have loved watching superhero movies since I was a child, and dreamed that I could become a hero one day. Now I understand that as long as I work hard to pursue my dreams and bravely shoulder social responsibilities, every day Everyone can become a superhero.” What makes Zhang Beiyu happy is that he also participated in the 2022 Spring Festival travel season and did his best to protect everyone’s way home during the Spring Festival travel season.
Although he is just a “veteran”, he never hides his “ambition”: he not only wants to do testing underwater, but also wants to learn underwater welding and cutting skills, as well as The most difficult and most demanding underwater blasting. “If you learn this skill, you can become the king of the underwater. When you burn, the earthquake will shake the mountains, and the water will spray out – that is a true hero!”
Recently, this young team The team was invited by Guangzhou Railway Group to conduct underwater inspection of bridges in the Xiangjiang River Basin for the first time. The equipment is connected and tested, the equipment is ready, the personnel are in place, the assault boat is launched, and the equipment is explored… “Everything is ready, diver No. 1 starts to launch!” Zhang Beiyu was seen upside down and fell into the river, flipping from the assault boat into the river and slowly descending. Diving to the bottom of the river, hundreds of kilograms of equipment made it difficult for him to change his position. His teammates on the shore gave him real-time guidance on how to change his position and conduct inspections based on the testing equipment. This time, he was mainly responsible for checking whether the bridge piers had hollows, holes caused by water erosion, and whether the steel bars were exposed. After nearly 2 hours of underwater work, he successfully completed the inspection task of Bridge Pier No. 3.
After the work was over, Zhang Beiyu and his colleagues shared their feelings with their friends: Underwater JM Escorts While exploring, I felt as if I had really become a “frogman”, swimming in the rivers and lakes inland. The affinity for diving, the sense of responsibility for bridge inspection work, and the love for the great inland rivers and mountains gave him a new ideal.
“I want to swim in China’s rivers and lakes and do physical examinations for all bridges! Protect the underwater safety of every bridge.” Zhang Beiyu is full of expectations.
The bridge inspection team took a rubber boat and used a dual-frequency depth sounder to collect timely information on the underwater surroundings of the bridge pier. Pictures provided by the Railway Readiness Ship Bridge Department
Before joining the bridge inspection team, Zhang Beiyu had always been attracted to diving work, but after studying After understanding the full set of testing procedures, these dazzling and complex testing equipment made him even more amazed at the power of technology. As long as he can master the operation of each instrument, he can Jamaicans Sugardaddy knows the status of each bridge very well. “It’s really hard to put it down. They will be my ‘super weapons’ from now on!” “Zhang Beiyu said happily.
Jamaica Sugar Bridge inspection has very high requirements for inspection instruments. Gao, in order to do a better job, the team members studied and explored various instruments through testing again and again. The testing technology was changing with each passing day. At the same time, the testing equipment was constantly updated with new materials and improved. Based on the original equipment, new detection equipment is used for the first time: three-dimensional real-time sonar and underwater pile basic rapid detection system
Three-dimensional image real-time sonar can collect real underwater images in real time. The surface displays the underwater terrain processing into a three-dimensional model, and the underwater structure can be seen intuitively on the shore; the rapid detection system of underwater pile foundation is like a mechanical diver, which can conduct underwater exploration in advance, and then, Divers can conduct targeted exploration of key parts based on the results it displays, greatly reducing underwater operation time, enhancing safety, and improving operation efficiency.
“Physical examination” results. It showed that the bridge was in good health and could be used safely. Zhang Beiyu and other team members worked together to successfully complete the inspection task.
In the past 4 years, this young bridge has been inspected. The team traveled through 12 inland rivers and successfully completed the inspection tasks of 88 bridges. In 2021 alone, 15 bridges were inspected, including the Yangtze River, Yellow River, Yalu River, Zhang River, Beijing-Hangzhou Canal, Ouchi River, and Wei River. The rivers are vast and the “hidden” scenery is breathtaking. “During the War of Liberation and the War to Resist U.S. Aggression and Aid Korea, the forefathers of railway divers fought bravely and guarded the road with their lives. transportation artery; todayThe mainland is prosperous and prosperous, and we, the younger generation, must use scientific and technological strength to contribute our youthful strength to the inspection of inland bridges. “Zhang Beiyu said.
