Wang Jiujun's spirit has been renewed for a long time

110 years ago, Zhan Tian, the "father of Chinese Railways", presided over the opening of the Beijing Zhangjiakou Railway, breaking the myth that Chinese people can't build their own railways. 110 years later, the Beijing Zhangjiakou high speed railway, a key transportation supporting project for the 2022 Winter Olympic Games, will be opened soon, which will open the world's leading intelligent high speed railway. The new generation of railway builders inherited Zhan Tianyou's spirit and vividly interpreted China's strength and wisdom to the world. Wang Jiujun is one of these adorable high-speed railway construction troops. (on December 8, the E-line of Guangzhou railway made a special report in the all media center of people's railway).

Wang Jiujun, born in September 1978, is now deputy director and senior engineer of Jingzhang Intercity Railway Co., Ltd. boutique engineering office. He is mainly responsible for the creation of "boutique engineering and intelligent Jingzhang", involving the planning, creation, inspection and evaluation of boutique engineering, the organization and promotion of scientific research topics, the implementation of engineering projects and the promotion of advanced tooling technology Wide communication, etc.

"the construction difficulty of Tsinghua garden tunnel is world-class. It passes through the densely populated area of Xueyuan South Road, Haidian District, Beijing, with many risks, high standards and great difficulties in construction organization. " Wang Jiujun said, "it intersects with Beijing Metro Line 10, line 15 and line 12 and runs parallel with line 13. In addition, it also runs through a large number of urban main roads and underground pipe networks. Among them, the minimum structural clear distance with line 15 is only 0.8m. " A set of exact data and accurate figures of

are enough to prove the difficulty of Qinghua garden tunnel and the meticulous work style of Wang Jiujun and Yan tan. At the same time, they also reflect the good spirit of Wang Jiujun who is not afraid of difficult risks, is brave in trying, is brave in testing water, is brave in exploring and is brave in challenging innovation.

in order to reduce the disturbance to sensitive buildings, the tunnel adopts shield construction method, which can avoid the disturbance to the existing infrastructure to the maximum extent, reduce the impact on people's lives, and reduce the noise pollution to the surrounding environment after the opening and operation. A 6031 a 6031 green water and green mountains are Jinshan and Yinshan. Protecting ecology, reducing noise, using green environmental protection materials and building a green and civilized city are not only the needs of the times, but also the future development trend of the construction industry. A 6031 a 6031 "Badaling Great Wall scenic area has very high requirements for cultural relics protection and ecological environment. Blasting here is like" earth moving on the head of Taisui " Wang Jiujun jokingly said, "but there are more ways than difficulties! We have innovated and adopted the new technology of precise micro blasting, which must not affect the precious heritage left by our ancestors. " A 6031 a 6031 is more difficult than that! Badaling tunnel is located in a very high risk area of soil structure, a little carelessness will cause collapse; there is a risk of underground water gushing, I don't know where the hole will produce a "big fountain".

one difficulty after another, one test after another, and one risk challenge after another. It tests Wang Jiujun's new idea of developing green and intelligent high-speed railway and the new long march of building a happy channel for Beijing Zhangjiakou high-speed railway. It has been proved that Wang Jiujun is braver and braver with more setbacks. A 6031 a 6031 Beijing Zhangjiakou high speed railway is about to open, a new starting point. Wang Jiujun continues to adhere to the construction concept of elaborate, fine, exquisite, and fine products, and strive to move forward, writing a new chapter of life. In the new era, there are tens of thousands of Wang Jiujun style good comrades in the railway family. (Shi Xuping)
