He is not tall, but healthy and stocky, with few words but clear thinking, praised but low-key and elegant. This is Bai Zhiyong, a national model worker and a senior surveyor of China Railway No.1 Bureau and No.5 Company.
During the period of 18, he only did one thing-engineering precision measurement. He is found in high-speed trains, subways, bridges, highways and tunnels in the north and south of the river. During the period of 18, he was most proud that he and his team accounted for one tenth of the 22,000 km operating mileage of China high-speed railway.
Perseverance, practice superb skills "Only when skills become instinct can we be comfortable in our work." This is Bai Zhiyong's pet phrase.
18 years ago, Bai Zhiyong graduated from Lanzhou Technical School and went to the construction site of Guangzhou Southeast West Ring Expressway of China Railway No.1 Bureau and No.5 Company. Since then, his life has been inextricably linked with one word-measurement.
Carrying a tripod and instrument box on his back, wading across mountains and rivers to make measurements has become his normal life. At the beginning of his career, Bai Zhiyong felt the lack of knowledge: "I graduated from a technical school. If I want to be a qualified railway builder and make achievements in my work, I can only change myself through learning. "
From then on, the outside work is learning. He taught himself a junior college and an undergraduate course, and often read until late at night. "Being good at learning and persisting in learning are the biggest characteristics of Xiaobai." Sheng Qiao, Vice Minister of Engineering Management Department of China Railway No.1 Bureau and No.5 Company, said.
Not only that, he also seized all his free time to exercise his professional skills. Take the level for measurement as an example. When he first entered the business, Bai Zhiyong took a level to the office after work, formed a height difference with the ground, tables and chairs, measured the height difference with a steel tape, and then measured it with a level. Repeat the operation until the fingertips are accurate.
Due to excellent professional skills, in recent years, he has won honors such as "National Youth Post Model", "Most Beautiful Young Worker", special government allowance of the State Council, national model worker, and the first central enterprise model. ...
Constantly innovating, leading the development level of the industry, doing repetitive work, doing new tasks, constantly innovating and improving the level are the words that Bai Zhiyong often teaches his disciples.
At the beginning of the construction of the Beijing-Shanghai high-speed railway with the highest construction level in the world, Bai Zhiyong received the task of accurately controlling and measuring the entire track bed of the high-speed railway. However, no matter how you measure it, the error is always too big.
When checking the equipment again and again, Bai Zhiyong found that the centering rod that must be used in each measurement has a design error of 5 mm, and the error of the whole ballast bed must be controlled at 3 mm. How to redesign the centering rod? Bai Zhiyong and the team keep trying and correcting.
Finally, they found a square iron block of 50 cubic centimeters, cut off a quarter of the corner to make the whole section smooth, and then stuck the iron block on the whole track bed during use. First test, the data is accurate!
This instrument was later named "Multifunctional Base Template Prism Adapter". It skillfully uses the characteristics of fixed die stability, overcomes the problem of large tripod error, and provides another basic guarantee for the accuracy and speed of high-speed rail.
Over the years, Bai Zhiyong and his team have been constantly innovating: 9 patents, such as "new standard for building deformation monitoring", "simple prism lighting device" and "shelter for precision measuring instruments", and 3/kloc-0 items of scientific research, papers and technology. ...
"I believe that' contributing to society' is' happiness'. On the road of precision measurement, I will continue to go on and write my own life trajectory. "
