The Beijing Zhangjiakou Railway, which was built 110 years ago by Zhan Tianyou, the father of China Railway, has become the pride of Chinese people. 110 years later, the new generation of railway builders inherited the spirit of Beijing Zhangjiakou and created a new generation of intelligent high-speed railway - Beijing Zhangjiakou high-speed railway, which not only opened a platform for the world people to communicate with each other for the 2020 Winter Olympics, but also showed the world China's wisdom, China's intelligent manufacturing and China's strength.

now is Wang Jiujun, deputy director and senior engineer of Jingzhang Intercity Railway Co., Ltd. boutique engineering office. It is precisely to inherit the spirit of Jingzhang for a hundred years, not forget the original intention, uphold the ingenuity, and be responsible for the scientific research, research, creation, exchange and promotion of "Boutique engineering and intelligent Jingzhang". In the face of world-class high-difficulty challenges, he took the initiative and was conscientious and responsible, so that one millimeter is not bad, one millimeter is not bad. When running through the Qinghuayuan tunnel, facing the crossing and parallel of four metro lines, he put the safety of dense and interwoven traffic network and urban center flow as the top priority, worked hard for five days and five nights, repeatedly reviewed the data, broke the routine, and innovated ideas, and changed the on-site pouring of concrete under the rail structure into a green and efficient fully prefabricated structure, so as to realize the excavation of the under rail structure and shield It has been carried out simultaneously, setting a precedent for the whole prefabrication and assembly technology in China. After the technology is put into operation, it not only improves the working environment, ensures the quality of the project, but also improves the efficiency. It has created a record of 24 meters of daily excavation and 474 meters of monthly excavation for the participating units.

If there is a little carelessness during the excavation of this section of project, it will collapse around and leak many places. He changed the shield tunneling into micro blasting technology, which not only protects the surrounding cultural relics but also protects the environment from pollution. In the construction of intelligent Jingzhang, he strictly controls the scope of various indicators and data, rigorous working attitude, mission like passion, never say die spiritual power, excellent professional knowledge, can stand the lonely persistence, and is meticulous All these endow Wang Jiujun with responsibility and responsibility as a railway man in the new era. "There is no best, only better" is a sentence he often talks about, which also shows his sense of quality.

now, the opening of Beijing Zhangjiakou high speed railway is just around the corner, and the quality of high-quality projects creates the quality of craftsmen. It is precisely because many railway builders, like Wang Jiujun, have not forgotten their original intention, taken the initiative and inherited the spirit of Beijing Zhangjiakou for a hundred years that they have achieved more and more brilliant achievements.
