The difficult times and amazing growth of the Qinghai-Tibet Railway, the Sichuan-Tibet Railway, and the Three Gorges Project
Construction machinery has challenged one super project, but one mountain is higher than one mountain. The waiting is unknown. The front may be a more difficult road to climb. The level of Chinese construction machinery is known to be in the past 20 years. Before the development, there was a super project called the real “difficult to go to the sky”. It is said that from the 1950s, our engineering experts conducted multiple explorations, but because of the difficulty, they stayed on the drawings. on. Where is the difficulty of the Sichuan-Tibet Railway? What is the test? Does the Qinghai-Tibet Railway also have a bumpy road that has lasted for decades? Pay attention to 21:45 on May 19th, "Dialogue" "behind the super project"!
Zhou Xianyu, editor-in-chief of "Construction Machinery and Management" magazine, told us that the Qinghai-Tibet Railway, which is well known, is actually divided into two phases. The first phase was repaired from 1958, and it was completed in 1984 until it was put into operation. It took about 26 years to complete. The first phase of the project. After repairing for such a long time, and 179 people died of high altitude sickness, it was very difficult to repair Lhasa. This project was temporarily dismissed. The most fundamental reason for this is actually the inability of engineering equipment.
Liu Feixiang, chairman of China Railway Construction Heavy Industry Group Co., Ltd., has been working on the Qinghai-Tibet Railway for five years and has deep experience. He fully agrees with Zhou Xianyu. The first paragraph from Xining to Golmud is completely human tactical and artificial. In the second paragraph 15 years ago, from Nanshankou to Lhasa, there was semi-mechanization, and all of these machines were imported. Liu Feixiang studied mechanical engineering in the university. He always thought about it, one day he could Develop some automated machinery equipment yourself.
Recalling the construction of the Three Gorges Project, Zhou Xianyi once interviewed when he was repairing the Three Gorges. At that time, the Three Gorges Dajiang was closed and needed a very large and heavy machinery to be constructed. At that time, a large part was actually foreign equipment, that is to say, China was At that time, it was not able to fully meet the demand. At that time, many experts sighed and said that the Three Gorges Project is an international column or an exhibition site of an international engineering organization. But after more than 20 years of development, China's construction machinery has been able to fully meet the large-scale construction in China.
