According to CCTV News on the 37th, about ten years ago, China had long been "bottlenecked" in the core technology field because it did not have an oversized diameter shield machine , so foreign companies and enterprises once made a huge statement and directly offered a sky-high price of 700 million yuan to China. It is because they insisted that "China will definitely not be able to build a shield machine." Ten years later, Yang Hui, a Chinese 80s shield machine designer, led the science and technology team to continue to work hard, and finally overcome thousands of technical problems surrounding shield machine, designed and manufactured a super-large shield machine independently developed by China, reversing the passive situation in my country's development in one fell swoop.
What exactly is a shield machine? In fact, it is an tunnel boring machine . Traditional mountain excavation requires explosives to blow up the mountain, and then manually clean up the residue, which is time-consuming and labor-intensive. With the shield machine, it can be achieved by "opening mountains" while "eating soil" and "cleaning" while "exhausting", saving time and effort. Someone has calculated that using a shield machine can save 90% of the construction period. In the past, it took 10 years to dig a tunnel, but with this guy, it only took 10 months.
But this technology has always been firmly in the hands of Western countries such as the United Kingdom, Japan and Germany. They also often use this technology to ask for prices all over the world. In 1997, when my country was digging a tunnel, it considered purchasing a shield machine from abroad. As a result, the other party directly offered 700 million yuan, and the operation and maintenance process were kept confidential in case we learned it. It can be said that at that time, China suffered a lot of cowards when it comes to problems such as shield mechanisms.
But the threat from the West also forced us to independently develop. Later, my country organized nearly 20 experts to continue researching and finally developed China's first domestic shield machine, and the price was only about 1/30 of that in the West. Not only that, after market testing, the quality of Chinese shield machines is very good, not inferior to Western products at all. Therefore, the Chinese shield-making machine with high quality and low price has been quickly sold around the world, quickly breaking the technological monopoly of Western countries, and occupying more than 70% of the global market share, becoming a leader in this technology field.
The key reason why China can stand out in a series of Western boring fields such as shield machines is the unremitting efforts of our R&D team, especially generations of scientific researchers. From domestic large aircraft to domestic aircraft carriers, from Beidou navigation system to the development of new crown vaccine , many people have noticed that China's scientific research team is not only fully localized, but is becoming younger and younger. Today, the post-80s and even the post-90s have become the main force in my country's science and technology industry, and they are striding forward with the dream of "a strong country in science and technology".
For a long time, China has attached great importance to the development of science and technology and the development of the country. "Made in China 2025" has provided the clearest top-level design for the strong rise of my country's industrialization, and the trade war initiated by the United States has forced us to accelerate scientific and technological innovation and independent research and development from the external environment. Therefore, under the combined effect of multiple factors, my country's scientific and technological strength and industrialization process have not only not been dragged down by the United States and the West, but have instead reached a new level every day and made new breakthroughs. Today, we can say with confidence that China's industry has a promising future and China's rise is just around the corner.
