"Ocean building blocks" stumped India engineers?
In today's rapid development of science and technology, large construction machinery has become a symbol of the country's comprehensive strength, among them, with the title of "king of construction machinery" shield machine, is even more attention-grabbing, it is like a huge "steel earthworm", shuttle underground, for the subway, tunnels and other projects to make great contributions, but recently the India media broke out, spending a huge amount of money from China to buy shield machine parts in India, but in the assembly process made difficulties in the assembly process What is going on?

The trump card of the "infrastructure madness".
If you want to uncover this "puzzle", we might as well turn our attention to China, as the world's second largest economy, China's achievements in the field of infrastructure have attracted worldwide attention, known as the "infrastructure madness", from the towering skyscrapers, to the criss-crossing high-speed railway network, and then to the super bridge across the moat, China's infrastructure has refreshed the world's cognition again and again, and behind this, it is inseparable from the rise of China's high-end equipment manufacturing industry, especially the breakthrough in construction machinery technology represented by the shield machine
Once upon a time, shield machine technology has been monopolized by Europe and United States, Chinese enterprises can only import at a high price, and even blocked by technology, Chinese engineers did not give in, they rose to the challenge, immersed in research, and finally overcame one technical difficulty after another, successfully realized the independent research and development and manufacturing of shield machine, now, China's shield machine not only broke the foreign monopoly, but also reached the international advanced level in terms of performance and quality, and the products are exported to more than 100 countries and regions around the world, becoming a bright business card made in China
The picture comes from the Internet
The "Jinghua" shield machine independently developed by China Railway Construction Heavy Industry Group, with an excavation diameter of 1607 meters and a total weight of more than 4500 tons, has created a world record for the construction of super-large diameter shield machine, which has been successfully applied to the reconstruction project of Beijing's East Sixth Ring Road, and has made an important contribution to solving the problem of traffic congestion in Beijing
"Episodes" on the way to "catch up"
In sharp contrast to China's infrastructure development, India's infrastructure level has been relatively lagging behind, in recent years, with the rapid development of the economy, India has also begun to increase investment in infrastructure construction, and has formulated an ambitious "catch-up" plan, of which the construction of an undersea tunnel connecting mainland India and Sri Lanka is an important project
The picture comes from the Internet
With India's current industrial base and technical level, it is undoubtedly "Arabian Nights" to complete this project independently, so they set their sights on China, hoping to realize their "submarine dream" with the help of China's mature shield machine technology
According to India media reports, at the beginning of 2020, India spent a huge amount of money from China Railway Construction Heavy Industry Group to purchase a super large diameter shield machine with a diameter of 1219 meters for the construction of undersea tunnel engineering, this shield machine is 80 meters long, weighs 2300 tons, has an installed capacity of 7200 kWh, has 350 meters of horizontal turning and super climbing ability, can be called "giant in the field of construction machinery", according to the plan, this shield machine will be disassembled into hundreds of components, shipped by sea to the port of Mumbai, India, Then on-site assembly and commissioning by Chinese engineers
Unexpectedly, the India side put forward a "special requirement" when signing the contract: they hope that China is only responsible for transporting the shield machine parts to India, and the assembly work is completed by India engineers independently, for this "sudden" requirement, Chinese companies are very surprised, after all, the shield machine is a highly sophisticated large-scale equipment, its assembly process is complex and high-tech, requires a professional technical team and rich experience to complete, India engineers have never been exposed to such complex equipment before, Rushing to assemble it is likely that various problems will arise and even lead to damage to the device

The "assembly" problem has sparked heated discussions
Despite repeated reminders from Chinese companies, India still insisted on "doing it yourself", and eventually, the two sides reached an agreement that Chinese engineers would return to China after completing the disassembly and packaging of shield machine parts, and would no longer participate in the subsequent assembly work, and the development of things was as expected by Chinese companies, and India engineers were completely dumbfounded in the face of this pile of "steel monster" parts
According to the Times of India, after arriving in India, the shield machine parts were stacked in the port for months without anyone being able to assemble them, and India engineers were faced with piles of parts and complex drawings, and they realized that assembling a shield machine was far more difficult than they thought
The picture comes from the Internet
After the news came out, it immediately aroused widespread attention and heated discussions in India, and some India media and experts criticized the government for being "too ambitious" and "not self-sufficient", believing that India blindly pursued "localization" in the absence of core technology, and would only eat its own fruits, and some people ridiculed that India engineers regarded Chinese shield machine parts as "Lego bricks", thinking that they could be assembled by just putting them together, but they found that they could not play at all
"Win-win cooperation" is the right way
In fact, the incident in which India purchased Chinese shield machine parts but could not assemble them reflects the huge gap between China and India in the level of scientific and technological development, for a long time, India has been overly dependent on imports in the field of science and technology, and its independent innovation ability is insufficient, resulting in it lagging behind China in many key technology fields
The picture comes from the Internet
Taking the shield machine as an example, after years of technology accumulation and innovation and development, China has formed a complete industrial chain and strong manufacturing capacity, and the product performance and quality have reached the international advanced level, while India is almost blank in this regard, and can only rely on imports to meet domestic demand
More importantly, Chinese enterprises have accumulated rich construction experience in the field of shield machines, and can provide customers with a full range of services from equipment selection, construction scheme design, equipment installation and commissioning, operation training, etc., while India also lacks corresponding experience and talent reserves in this regard
Therefore, for India, instead of blindly pursuing "localization", it is better to strengthen scientific and technological cooperation with China, learn from China's advanced technology and experience, and strive to improve its own scientific and technological innovation capabilities, after all, in today's world, scientific and technological development is changing with each passing day, only by adhering to open cooperation, mutual benefit and win-win results, can we jointly promote the progress of human civilization

Epilogue:
The story of India's "assembly" of Chinese shield machine parts may be just a microcosm, which reminds us that on the road of scientific and technological development, we must be ambitious, down-to-earth, and adhere to open cooperation, do you think India can finally successfully assemble this shield machine?
