The export of shield machines from Europe and the United States is limited, and the situation is embarrassing!
After the reform and opening up, China's economic, scientific and technological development has entered"Fast lane"In particular, foreign brands and enterprises have attacked the Chinese market in a big way, and Chinese companies have grown rapidly, including leading technology companies such as Gree, Huawei, ZTE, and Unisplendour. With the rise of more and more science and technology enterprises, we have also made great progress in advanced technology fields such as high-speed rail, C-ring, wind tunnel, etc'Steady'Direction'Strong'This is a historic leap.
In order to consolidate its hegemony and restrict Chinese companies such as Huawei, the United States has included Huawei in the list of entity enterprises, changed chip standards, and signed a tripartite agreement with its allies to make Huawei unable to use chips within three years.
However, Chinese companies represented by Huawei did not compromise, but withstood the pressure of the United States and chose 100% independent research and development, and successfully realized it in the fields of lithography technology, quantum chips, steel hand tearing, photonic chips, and 5G"Overtaking in corners"。This is undoubtedly a resounding slap in the face to the Americans!
In the so-called science and technology war, whoever has mastered cutting-edge science and technology will have the initiative in 30 years, and in Hedong for 30 years, Hexi for 30 years, no one can say what will happen in the future! Even if it is a shield machine, it must be imported from the United States, Germany and other European and American countries, even if the price is asked, it can only"Dumb eat coptis"For example, in 1997, we bought two second-hand shield machines from Germany, **up to 7 million yuan, which is literally"Slaughter"！for example, in 1997, we bought two second-hand shield cars from germany at a price of $700 million!
Not to mention that when we visited the TBM in Germany, their engineers threatened us that China would never build a TBM, and the United States and Germany did not even allow us to visit their factories and restricted us. However, to the surprise of Europe and the United States, in 1997 we bought two used TBMs from Germany, then bought 130 more, and 8 years later, we finally built the first TBM, which shocked the world!
As a kind of underground"Super Drill", the shield machine has been taken in the fields of roads, water conservancy, seabed, underground infrastructure, etc"Excavators"form. Previously, this area was monopolized by the United States and Germany. Later, in order to get rid of our dependence on Europe and the United States, we set up a shield machine R&D team in 2002 and launched the 863 program. On the basis of dismantling the German shield machine, we have achieved innovation and successfully developed the China Railway No. 1 shield machine, which solves the neckline problem.
In September 2020, we successfully developed the 1000th Yuehai No. 14, occupying 90% of the domestic market share, no longer relying on imports from Europe and the United States, and achieving self-sufficiency! In terms of road warheads, we also occupy a leading position in the world, producing a large number of giant road warheads, surpassing Europe, America and Germany, occupying 65% of the world market share, becoming the world's largest exporter of shielded road warheads! As far as I know, my country has banned the export of large roadheaders to Europe and the United States, which is covering your ears and stealing bells!
As the saying goes, through the unremitting efforts of countless scientists, we have a wide range of expertise in the fields of chips, shield machines, high-speed rail, and steel'Overtaking in corners', Huawei succeeded'Breakout'and become our backbone! If the U.S. continues to sanction Chinese companies, then we will ban the export of tunnel boring machines, trolley steel, and high-strength steel to Europe and the United States. This is our last'Hole cards', we have to give them a little color to see! If you agree, don't hesitate to support us!
