Qinhuangdao this enterprise once again uses its strength to show the wisdom of Chinese manufacture
In the past few days, in the workshop of China Railway Shanhaiguan Bridge Group Co.,Ltd., workers are busy with a “Wuhuan (five rings) bridge”. The bridge, which is under construction, is a key bridge on Yanchong Highway (a highway from Beijing's Yanqing District to Zhangjiakou’s Chongli District), which is one of the important passages for the 2022 Beijing Winter Olympics, and also the first bridge shaped in “five rings" in China.
Su Jianxin and his colleagues at the Quality Center are doing non-destructive testing for the first set of annular steel structures in the “Wuhuan (five rings) bridge”. “This is the one-sixth of the first ring structure of the bridge. Because of the ring shape, it is very difficult to weld. The test is even more rigorous and meticulous.” said Su.
The five rings bridge is composed of various twisted type plate units, and each plate unit has different twisting degrees. If the traditional method is adopted, the material consumption of tooling would be large, and the cost of labor and energy would be very high. In order to solve this problem, the large seven-roll steel plate leveling machine is proposed to process the fan-shaped steel plates into round ones by the steel plate team of CRSBG. After repeated rounding experiments, the radian of the processed bottom plate fully meets the technical requirements of no more than one meter one millimeter deviation. Therefore, the production efficiency has been greatly improved, and the production cost has been effectively controlled.
The workers of the crane team and the flame-cutting team cooperated and worked overtime together to ensure the matching and accuracy of the next process. Flame cutting is a key process in production preparation, each steel plate needs to be cut according to the process requirements before it goes into the next process, and the workload is very heavy. In order to ensure that the flame cutting work can smoothly link up and reduce the waiting time, the drivers of the crane team try to drink as little water as possible to reduce the frequency of getting off the crane, and ensure that the flame cutting machine works without interruption.
2022,
When the eyes of the world focus on the Beijing Winter Olympics,
This highway will impress the people by the natural beauty of the ice and snow along the road.
Coupled with the special bridge landscape design, it will leave the world with an unforgettable “Olympic road”!
Qinhuangdao CRSBG will once again show the wisdom and pride of the
“Made in China”!
