Guan Yanan: the 1 millimeter error can be identified by the sense of hand
origin: Shandong commercial newspaper
Hong Kong Zhuhai Macao Bridge is the longest, most difficult construction of the cross sea bridge in the world, it will be through Zhuhai after the completion of the bridge. Three places in Macao and Hongkong. The most difficult part, is a section of 5.6 kilometers long submarine tunnel, the construction process is complex, the construction standard is extremely harsh, the personnel involved in the construction can be called skilled craftsmen. Among these skillful craftsmen, there is a "great power craftsman" of "sea bottom embroidery" - Guan Yanan, who can judge the gap of one millimeter by only hand, and is known as the first person of the "deep-sea fitter" in China. Not long ago, he also won the title of "the most beautiful worker in the country" and "the most beautiful worker in Qilu".
work in Yanan
tube Yanan, Weifang people, Zhuhai Macao Bridge Island tunnel project V engineering team fitter, responsible for pipe outfitting and the installation of ballast water system in pipe Homework. He has successfully completed the 18 undersea tunnel docking task by installing the immersed tube equipment. At the beginning of 2013, Yanan came to Zhuhai's Ngau Tau island and became a member of the island tunnel construction. He is responsible for the sunken outfitting operation, the guide rod and the guide bracket have high installation precision, and the gap gap at the joint should not exceed 1 millimeters, and the pipe Yanan has made a zero gap. Since participating in the construction of the bridge, more than twenty thousand screws have been screwed through the hands of Yanan. What he often says to his young colleagues is to "check again", emphasizing that the most important thing is "repeated inspection". Xiao Zhang, the same team, said: "master the screws should be checked three times." For a long time, Yanan can only feel the error of 1 millimeters based on its handle. In May 7, 2013, the first section of the seabed tunnel of the Hong Kong Zhuhai Macao Bridge was successfully installed, and the "deep sea first kiss" was successfully realized. The colleagues in Yanan and the aeronautical repair team made a beautiful answer.
Yanan is accustomed to taking notes on each repaired machine and every repaired part. Each detail is recorded in a personal "repair log". What's the case and how to deal with it is "recorded." From now on, he has written four thick books, and he will take the time to know new things in his spare time. In these "cultural relics", in addition to the text, there are also his own "Diagrams". Now he has also passed the habit to the apprentice. "What I like most at ordinary times is the sound produced by hammering." Walking in a wet immersed tube, tube Yanan carefully inspected the installed equipment. Now, the harbour Zhuhai Macao Bridge undersea tunnel has successfully completed the 24 section of the immersed tube butt, and the subsequent immersed tube still needs the "great power craftsman" to carefully install each equipment and connect each line. "My wish is to drive a car to Hongkong in the future and take a circle round the tunnel from my sea floor, because this is what I have done for so many years, a section of pipe butt, and feelings for it."
