Never let down the expectations of the party and the people
[The Red Love of 100 Academicians]
I am grateful for the cultivation and education of the party and the people from the bottom of my heart, which spurs me to follow the party and serve the people for the rest of my life.
So far, Sun Yongfu still treasures the snow and mud from Tanggula Mountain, which was collected and given to him by the builders at the Tanggula Pass of the Qinghai-Tibet Railway at an altitude of 5072 meters. It is very precious.
What will happen to the Qinghai-Tibet Plateau at the age of 59? The memory of Sun Yongfu, former executive vice minister of the Ministry of Railways and academician of the Chinese Academy of Engineering, is still clear. It was 2000. At the Tuotuohe Soldier Station, 4,500 meters above sea level, when he got off the off-road vehicle, he instantly felt dizzy, his feet swaying like stepping on cotton.
Because blood oxygen saturation was too low, in October 2004, Sun Yongfu suddenly collapsed while inspecting a bridge project. At that time, snow was floating in the sky, but big beads of sweat popped out of his forehead. “At that time, knowing what people were thinking when they were dying, I felt that I couldn’t carry it this time.” He said.
The construction of the “Tian Road” cannot circumvent the three major global engineering and technical problems of “permafrost, plateau hypoxia, and ecological fragility”. After receiving the task, Sun Yongfu only said one sentence: “The Qinghai-Tibet Railway has attracted worldwide attention, its mission is glorious, and its responsibilities are heavy. It will never fail the expectations of the party and the people!”
The oxygen content along the Qinghai-Tibet Railway is about 50% to 60% of the plain area. The construction team must not only be able to go up, but also stand firm and do well. This is the primary problem to be solved in the construction of the Qinghai-Tibet Railway. To this end, Sun Yongfu organized research and established a complete medical and health security system, creating the miracle of “zero death” in large groups of high-altitude construction.
In order to solve the problem of permafrost and ecological fragility, Sun Yongfu changed the passive method of “covering quilt and heat preservation”, cooling the foundation by regulating radiation, convection, and transmission, maintaining the stability of the engineering structure, and creating the speed of opening and operating the permafrost railway. Records above 100km/h. He asked all construction teams to use technology and environmental protection, and successfully developed wildlife migration channels and plateau vegetation restoration and reconstruction technologies.
In July 2004, the first batch of Tibetan antelopes successfully passed the underpass of the Wubei Bridge on the Chumar River in Hoh Xil, forming a vivid scene of the harmonious coexistence of railways and wild animals.
Relying on scientific and technological innovation, and from an overall, overall, and dynamic perspective, Sun Yongfu handed in an excellent answer sheet as a strategic scientist. On July 1, 2006, the Qinghai-Tibet Railway was opened to traffic. The history of Tibet’s unreachable railways came to an end, and many of the world’s greatest were born: the longest plateau railway, the highest plateau railway, the longest railway crossing the frozen ground…2008 In 2004, the Qinghai-Tibet Railway project won the special prize of National Science and Technology Progress Award.
On the 80th birthday of this year, Sun Yongfu received a congratulatory letter from the Chinese Academy of Engineering: “You are a leader in railway construction in China. Beijing-Kowloon allows the old districts to realize the dream of development together. You are a practitioner of China’s railway reform. You have promoted the listing of railway companies and the decoupling of non-transportation companies, starting my country’s progress from a major railway country to a powerful railway country!”
“Today, my country can independently design and build high-speed railways with different speed levels and different geographical environments, ranging from 200 kilometers per hour to 350 kilometers per hour, from the tropics to the frigid zone, including the windy sand zone, which is unique in the world.” Sun Yongfu said.
