India, although geographically our neighbor, is "alienated" from us in all respects. Although we have always advocated "good neighborliness" and tried to "build good relations" with our neighbors, it seems that India's neighbor does not buy it.
It's either friction or friction on the way. Therefore, we are very concerned about India's every move, for fear that this restless neighbor will make some "small moves".
Previously, India had spent a lot of money to order all the shield machine parts from us, only to find that it could not be assembled at all. What's going on here?
What the hell is a shield machine?
To understand this problem, we must first know what a shield machine is. At first glance, the name "shield machine" is indeed bluffing, but it is actually a "tunnel boring machine".
But it's not a simple tunnel, and you can't think of it as a simple machine like an excavator. On its body, it is full of various "high-precision" scientific and technological content.
It is not a single piece of equipment, but a whole composed of a series of complex systems such as shield shell, slag removal system and sludge discharge system. It is generally used for excavation tunnel work deep underground. When working, it relies on the blade winch at the front to crush and propulse.
Basically, whether it is a complex terrain or a variety of solid rocks, it will be crushed into powder in front of it, and then cleaned up as silt.
In order to ensure that the newly dug tunnel does not collapse, there is usually a mixer to accompany the operation. This side of the shield machine will open up the space, and the other side will fill the key parts of the mixed cement mortar to ensure the stability of the tunnel.
The shield machine is equivalent to a "star", although it is the position of "main C" in the whole construction process, but in order to ensure that it can successfully complete the task, it often needs a variety of machinery to assist the work. Because the construction process is very complex, the number of people in the entire construction team will definitely not be small.
And the shield machine is also particularly good, that is, when it is working underground, it will not damage the surface, and can quietly "pass through the city".
In the past, when some cities built subways, they would carry out a lot of open-pit excavation operations. In order not to affect the construction, the entire surface section of the subway line will be blocked.
As a result, not only did the original road be destroyed, but the road had to be re-paved after the construction was completed, which invisibly increased the financial burden.
The progress of some construction units is very slow, and once the road is closed, it will be half a year, which will cause great traffic inconvenience to the surrounding citizens.
However, if the shield machine is used, it will not only greatly speed up the progress of the project, but also minimize the damage. But unfortunately, because the cost of the shield machine is very high, basically except for the national unit, few construction companies will have it.
Therefore, the projects that can generally use the shield machine are quite large projects. Basically, it is not a national project, but it has to be a regional project. Not only will it attract the attention of the local people, but at the beginning and end of the project, there will be various "big people" on the scene to guide.
Why is India spending a huge amount of money on shield machines?
As we all know, India has always been eyeing our southern Tibetan region. Because the southern Tibet region is excellent in terms of natural resources and geographical location.
But fortunately, we are separated from India by layers of mountains, and India can only cause friction in places such as Alashankou, and cannot project large-scale troops.
But as the saying goes, "If you are not afraid of thieves stealing, you are afraid of thieves worrying." India has not taken a fancy to our southern Tibet region for a day or two, and in order to overcome the obstacles between China and India, India can be said to have racked its brains. If you want to cross the mountains, there are only two roads, either bridges or tunnels.
But no matter what it is, we can only think about it, after all, once they have actions that harm us, they will be strangled in the cradle.
But India doesn't know whether it is out of practical needs or wants to show its strength, after all, many places of its neighbor's high-speed rail are already "county to county". As a big country in the East, the infrastructure is still a mess, and his face is really "unbearable".
So, with no engineering experience at all, they decided to build an undersea tunnel. The undersea tunnel was planned to be built in 2015 at the same time as India was building the Mumbai-Ahmedabad high-speed railway.
Of course, with India's infrastructure strength, it is impossible to build a very long undersea tunnel. The total length of this tunnel is about 20 kilometers, and only 5 or 6 kilometers can be called an undersea tunnel.
And due to the limitations of India's local engineering technology, the progress of the project has been slow. During the construction process, work was always stopped for various reasons. So much so that the high-speed rail in the same period has long been opened to traffic, and its own tunnel plan is still a mess.
In fact, in the final analysis, there is still a lack of shield machines. In the face of India's complex geographical environment, only the shield machine can cope with it.
Although India's overall national strength is also rising, the "high-precision" equipment of the shield machine cannot be built in a day or two. I think that back then, we were also "stuck" by foreign countries, and it took "a lot of effort" to develop it.
In order to speed up the construction progress, the Indian government could not build it itself, so it had to buy it from abroad. Looking at the world, we are the only ones who dare to be called "infrastructure madness".
Therefore, although the two sides are tense on the surface, business still has to be done, so in 2020, India spent a huge amount of money to buy shield machines from the mainland.
The shield machine purchased by India was developed by China Railway Construction Heavy Industry Co., Ltd. In the past, buyers demanded that it be assembled and used immediately if it could be pulled into the country.
And in order to save follow-up trouble, it is generally required to send some engineers to follow, so that small problems that may arise can be dealt with at any time.
However, India has put forward a special request, that is, it should be packed and pulled into their own country, and then assembled by themselves. For this requirement, discerning people know the "little ninety-nine" in it.
It is nothing more than that India wants to get a glimpse of the internal structure of the shield machine in our group, so that it can be copied secretly, and even directly boast that it is made by itself.
And if it can be assembled in your own country, you can make a lot of hype about your own people. It can not only show the strength of the Indian government, but also make the people "proud" by the way, which can be described as a win-win situation.
Whoever makes us confident in our products, although we all know this idea in India, but we also know that even if you tell you how the machine works, you can't do it.
However, in line with the fact that the customer is "God", Heavy Industry still carried out sub-packaging and transportation according to the requirements of the buyer. And in order to better serve customers, our heavy industry group has also made some adjustments according to the needs of buyers, such as improving the climbing ability of the equipment.
And in order to ensure the reputation of "Made in China", the heavy industry group also carried out various tests before leaving the factory to ensure that customers are satisfied with the use after getting their hands.
When the sub-assembled TBM was pulled to the Mumbai dock, the Indian government was caught in a very "money-burning" game. In order to guarantee 100% "Make in India", the Indian government has rejected the technical guidance experts we have sent.
In order to ensure the smooth assembly of the shield machine, the Indian side has invested a lot of financial resources, and has also found many local engineers and experts to study together.
But if the shield machine can really be developed through this simple split, the mainland will not have to waste so many years on it. So in fact, after India threw a lot of money here, it still didn't make progress for many months because the parts were too complicated.
This makes the face of the Indian government very shameless, after all, because the shield machine is too bright, many people in India are also paying attention. If you can't assemble it, it's a real shame.
But this kind of thing can be successful without urgency, you must know that there are many "high-precision" technologies on the shield body. Although it may not be as good as the lithography machine, it is also the "first brother" in the field of infrastructure. Many large-scale projects do not have a shield machine, no matter how beautiful and ingenious the drawings are, they can only be drawings.
There is no way, but there is nothing to be done. Whoever has already rejected all kinds of help from the Chinese side before, and then goes back to ask Chinese experts to guide them, will not be losing face abroad.
So the Indian government turned its attention to the West. The technology of the Western world is so advanced that it is not impossible to assemble it like itself.
As a result, the Indian government has paid a lot of money to hire specialized engineering experts from the UK to provide guidance, but it has been unable to do so. There has been progress, but it is true that there is not much.
Because the entire length of this shield machine is close to 100 meters, and it weighs 1,000 tons, far exceeding the previous machines produced in the UK.
It is unlikely that they will be able to find Chinese experts to help assemble it, because shortly thereafter, a clash broke out between the two sides at Alashankou. The incident here not only caused casualties among our personnel, but also directly led to the escalation of the situation in the region.
Originally, the two sides had many festivals in history, and India did not "stab the knife" on the Tibet issue on the mainland, which has led to further ossification of relations between the two sides.
If we want to continue to interact as before, if the Indian government does not make obvious "icebreaking" moves, I am afraid it will be difficult to alleviate it. India's tunnel plans have been put on hold indefinitely because the TBMs have not been put into operation.
In fact, for the "high-precision" engineering equipment such as the shield machine, it is already a great tolerance to be able to export to countries like India that are constantly making "small moves" behind their backs. But I didn't expect that India would have to make inches again and again, and the "bitter fruits" caused by this could only be paid by India itself.
end
It is a simple and easy-to-understand truth that cooperation can achieve win-win results, but some countries have never understood it. It is hoped that after tasting the "bitter fruit" a few times, the neighboring countries can wake up, after all, peace is the only way out for development.
