At 10:50 on June 29, Zhongchuan Airport of Lanzhang High-speed Railway to Wuwei East Station was put into operation. The high-speed rail only takes about 5 minutes to pass through the new Wusheling Tunnel, from the first generation of Wusheling to the third generation of Wusheling Tunnel, more than half a century of vicissitudes of life, witnessing the perseverance and growth of railway people, and the spirit of Wusheling has also been integrated into the spiritual genealogy of railway people.
Wusheling generation tunnel builder
In 1952, with the completion of the Tianlan Railway, the construction of the New China Railway to Xinjiang became the ardent expectation of the people of the whole country. If the railway wants to enter Xinjiang, it must be opened at the gate of the Hexi Corridor in Wuwei.
Whether it is General Huo Quai's westward expedition to the Xiongnu, or Tang Xuanzang's westward expedition to learn scriptures, starting from Chang'an, Wusheling is the gateway to the Western Regions.
In October 1952, the construction of the Lanxin Railway began, and the crossing of the Wusheling Ridge at an altitude of 3,000 meters became a key project for the construction of the Lanxin Railway.
The total length of the Wusheling crossing project is 47 kilometers, and there are 7 tunnel groups, of which the total length is 967. The construction task of the 8-meter Wusheling tunnel is the most arduous, the technical difficulty is the most complicated, the tunnel started construction in July 1953, during the construction, more than 30,000 people of the road construction team has gathered here, many workers are from Lanzhou to walk more than 150 kilometers, to the construction site.
This is the first generation of Wusheling tunnel, limited by technology and conditions, when the line crosses Wusheling Ridge, the line design is used to extend the line to reduce the slope and improve the climbing ability of the train.
In 2006, the Wusheling extra-long tunnel of the second line of Lanwu was completed and opened to traffic, and the old Wusheling tunnel ceased operation after 52 years of operation, becoming a witness to the development of the railway.
The second generation of the Wusheling Tunnel
The second-generation Wusheling Tunnel originated from the construction of the second line of Lanwu in March 2003, and the 20.05-kilometer-long Wusheling extra-long tunnel with a total length of 20.05 kilometers was completed on August 23, 2006, which greatly shortened the distance of the first-generation tunnel and increased its transportation capacity rapidly.
In June 2019, the construction of the new Wusheling Tunnel in the Lanwu section of the Lanzhang high-speed railway officially started, with a total length of 17.125km and a design speed of 250km per hour, making it a double-line extra-long tunnel. As the third-generation Wusheling tunnel, this tunnel is parallel to the second-generation Wusheling tunnel, and the existing inclined shaft construction of the second-generation Wusheling tunnel is effectively used for construction and the existing line ventilation is used.
Three generations of Wusheling Tunnel
Zhang Zhenqiong, commander of the Tianzhu Headquarters of the Lanzhou Engineering Construction Headquarters of China Railway Lanzhou Bureau Group, said that the opening of three generations of tunnels on a mountain is unique in the country. More than half a century of hard work and courage have also brought together the spirit of "not afraid of cold, not afraid of landslides on high slopes, not afraid of hardship, not afraid of difficulties". Encourage generations of Lan Tieren to forge ahead.
Construction of the three-generation Wusheling Tunnel
Miao Qi, deputy director of the Tumen Line Workshop of the Wuwei Public Works Section of China Railway Lanzhou Bureau Group, has been working in the Wusheling area for more than 20 years. She said that the spirit of Wusheling was born in the old Wusheling tunnel, inherited in the Wusheling extra-long tunnel, and in the construction of the Wusheling high-speed rail tunnel, it has become a spiritual source of morale, and the spirit of Wusheling is the precious wealth of railway people, and she will continue to inherit this spirit, stick to her own post, and ensure the safe travel of passengers.
In 2004, the construction of the "Wusheling Extra-long Tunnel" began, and Chen Yonghong was dispatched to participate in the installation and commissioning of catenary equipment in the tunnel, supervision and acceptance, defect rectification, and stayed in the Wusheling Ridge of "midsummer snow, cold and skull" for more than two years. In 2013, after the Lanxin high-speed railway intervened in advance, Chen Yonghong took the initiative to ask Ying to work in the high-altitude racecourse section.
"With the persistence of the three generations of Wusheling Tunnel and the 20 years of the Plateau Railway, I have witnessed the development of China's railways and reaped happiness from the struggle. In the future, I will faithfully perform my duties, inherit and carry forward the spirit of Wusheling, continue to protect the 'world's first high-speed rail tunnel group', and contribute to the development of railways in the new era." Chen Yonghong said.
