Exporting shield machines to India, the natural line of defense on the Sino-Indian border has been dug through by India向印度出口盾构机，如今中印边境的天然防线，被印度挖穿了

 India has finally become the number one in the world in terms of population.

India is a magical country. It is extremely confident in all aspects and often brags about its military strength. As everyone knows, its military equipment basically relies on imports and is "made by all countries". India spent a lot of money to buy 8 shield machines from China in 2020. Their original intention was that they originally had domestic infrastructure needs, and the second was to steal our technology through imports. Why does India buy Chinese shield machines? Before there was no shield machine, explosives were used to dig tunnels, which was time-consuming, labor-intensive and dangerous, but since the world has a shield machine, it is different. The shield machine is known as the king of construction machinery. It is efficient and safe to dig, not to mention shortening the construction period. It is also convenient. Soft soil layers and rock layers all give way in front of it, and it can withstand soil layers and groundwater. Under the protection of the shield, the soil is discharged smoothly. But the shield machine is good at building subways and tunnels!

Although India's population is comparable to that of China, it can only hold its own in various technologies. Our country is a world-renowned "infrastructure madman" and has already overcome this technology. In addition, India's domestic infrastructure is not particularly perfect. As the saying goes: Only roads can lead to wealth. Modi must know this truth, so he wants to do a big job in India. The idea of building three subways in a row at once is enough to create momentum, but the follow-up is also quite disappointing. Remember the high-speed rail that was contracted to Japan before? It's still on hold now.

China's road to shield machine The shield machine is actually not our first thing. It started in the UK and was well developed in Japan and Germany later. As we all know, China's infrastructure construction started late, and it was incomparable with the infrastructure construction of developed countries before. In order to better complete the urban construction, we purchased several shield machines from Germany. With the shield machines, everything is much more convenient and the construction process is also accelerated, but the machines will need to be repaired sometimes. It is also the beginning of the "money trapping" in developed countries. Without technology in hand, they also know that our country cannot solve this kind of problem, so they start asking for prices. Whoever has the technology has the greatest say, just like the current chips.

But China is different from other countries. Where there is oppression, there is resistance. In order not to be controlled by other countries, engineers in our country rolled up their sleeves and invented by themselves. Sure enough, the emperor paid off. Finally, in 2008, my country's first shield machine came out, and the days of Germany's toughness came to an end. Everyone knows that as long as the technology conquered by China, other countries will have no price advantage in the world. India imported the shield machine before using it. After all, the money of each country is not blown by the wind. After shopping around in India, I finally chose the Chinese shield machine. Soon, China completed the manufacturing in March 2020 and sent it to India. However, the heavy and tall shield machine is also a difficult problem to transport. Since the whole machine cannot be transported, it can only be disassembled. At this time, India began to "play monsters" again and invited British experts to check the quality problems. However, real gold is not afraid of fire, and the quality of our machines has completely passed the test. More than one hundred parts and 13 super trucks came to Mumbai, India. It stands to reason that after the machine was shipped to India, our engineers had to help them assemble it before it could be considered a complete delivery. Unexpectedly, when it was shipped to India, it said: the machine has been delivered, you can go back, and the simple assembly is left to the Indian experts! India's heart is: it spent a lot of money to buy the machine, and wanted to steal Chinese technology during the assembly process. However, the facts have also proved that India has overestimated their strength! Indian experts have been tinkering with these parts for several months, but they have been unable to assemble them, and the parts are still the same pile of parts. Not to mention stealing technology, assembly is a big problem.

If the installation is not successful, it will be blamed. The Indian side said: there is a problem with the material of the shield machine parts, otherwise how could the assembly fail! But don't forget, you have asked British experts to help you check it out before, and China does not only export to India. In 2016, Singapore purchased 10 shield machines from China for subway construction; in 2017, Russia purchased 5 shield machines from China; in 2019, China exported the first shield machine to Africa; in 2019, the city of Ismir, Turkey built The subway also uses Chinese shield machines. Why didn't they say that there was a problem with the quality, but India provoked the thorns. In fact, it was "face" that was at fault. at last,

Exporting shield machines to India, the natural line of defense on the Sino-Indian border has been dug through by India

The Indian side can only pull their faces and ask us to send a few experts to help them solve the problem. But unfortunately, the severe epidemic and the tense Sino-Indian border made it impossible to obtain permission to allow Chinese engineers to enter India.

You see, this is a joke. India still needs to correct its arrogance, put down its dignity, and learn a lot, so as to change the situation of "made by all nations"!

According to news on the Indian Internet, the Indian army dug through the tunnel from Tawang to the Sera Pass in southern Tibet. Relevant photos and videos were widely disseminated on the Internet. However, according to the publisher, these photos and videos proving that India dug through the tunnel were taken 4 months ago, that is, in January this year, and the construction was basically completed at that time.

In fact, Sera Mountain Pass once shined brilliantly in the counterattack against India that year. India was used here by our army to play a textbook-level interspersed siege tactic, and the place is therefore well known to the outside world. Because the altitude difference from the foot of the mountain to the mountain pass is huge, reaching the point of 2 kilometers, this place is known as a natural line of defense on the Sino-Indian border.

But looking at it from another angle, this kind of terrain makes it extremely difficult for the defenders to supply supplies, especially in peacetime. The heavy snow that closes the mountains every year is a test of the defenders' lives. After the counterattack against India that year, we took the initiative to retreat and gave up this line of defense. It was also because our logistical capabilities were unsustainable, and our soldiers could not be sacrificed in vain. Up to now, with the development of drone technology and the advancement of remote guidance technology, this terrain advantage has been negligible for us, so we have not repeatedly competed with India for this place. It is better to let the Indian army spend a lot of lives every year. And physical "wounds".

In the past few decades, India has wanted to build roads in Tawang more than once, but on the one hand, there are infrastructure capacity and internal corruption problems, and on the other hand, there is also a lack of professional construction machinery. And that all changed rapidly in 3 years. In the first few months of the bloody conflict on the Sino-Indian border in 2020, India successively imported 8 shield machines with different application scenarios from my country. One of them has a diameter of 12.19 meters. At that time, some people in the country joked that the Indians bought these shield machines and could not install them, and they had to spend money to hire Chinese engineers to help them install them.

Although India has not claimed to the outside world whether it is using Chinese shield machines, in fact, it is inevitable to use shield machines for projects of this level.

Frankly speaking, with the completion of the "Wanda-Sala Pass" tunnel in India, the threat level of the Indian army on the southwestern border of China will completely change. The total length of this tunnel is more than 2,500 meters. In addition to the main tunnel, there is also a 980-meter and 1,200-meter leading road. In terms of wartime conditions, compared to before, India can use this tunnel to directly mobilize troops and equipment to reach the front line, and can avoid the advantages of Chinese satellite surveillance. With the mountain itself as cover, it is difficult for our army to notice India's strategic intentions in the first place. For the Indian army, which has always liked sneak attacks and undeclared wars, this tunnel will greatly enhance its strategic advantage on the Sino-Indian border. It can be said that the hidden dangers of India in my country's border areas for a long time are now taking advantage of the window period of the Sino-US game to take shape rapidly.印度，终于在人口上如愿成为了世界第一。

印度是一个神奇的国度，在各方面都极度自信，还经常吹嘘自己的军事实力，殊不知，他的军事装备基本靠的是进口，属于“万国造”，掩耳盗铃的本事学得一绝。印度在2020年花大价钱从中国买了8台盾构机，他们的初衷是，本来也是国内有基建需要，其次就是想通过进口，来偷学我们的技术。印度为什么要买中国的盾构机？在没有盾构机之前，挖隧道都是用炸药，费时费力还危险，但是自从世上有了盾构机，那就不一样了。盾构机被称为工程机械之王，挖起来效率高还安全，缩短了工期不说，还方便，什么软土地层、岩石层，在它面前统统都让道，而且能够承受土层和地下水的压力，在护盾的保护下顺利排土。可是说盾构机建地铁、打隧道一把好手！

印度虽然人口可以和中国媲美，但是各项技术就只能望其项背，我国是全球闻名的“基建狂魔”，在这一项技术上早已攻克。还有就是印度的国内基建还不是特别完善，俗话说：路通才能财通。莫迪肯定知道这个道理，于是便想在印度大干一场。一下子想连修三条地铁，造势是挺足的，但是后续也让人挺失望的，还记得之前承包给日本修建的高铁吗？现在都还搁置在那里。

中国的盾构机之路盾构机其实也不是我们先有的东西，它是始于英国，后来在日本和德国得到很好地发展。众所周知，中国的基建起步晚，以前和发达国家的基础建设根本没法比。为了更好地完成城市建设，我们便向德国购买了几台盾构机，有了盾构机，一切就方便了很多，建设进程也随之加快，但是机器就会有需要维修的时候，这也是发达国家“圈钱”的开始。没有技术握在手，他们也深知靠我们国家是无法解决这类问题，于是便开始漫天要价。谁有技术，谁的话语权就最大，和现在的芯片如出一辙。

但是中国和其他国家不一样，哪里有压迫哪里就有反抗，为了不想被别的国家牵制鼻子走，我们国家的工程师便撸起袖子，自己发明创造。果然皇天不负有心人，终于在2008年我国首台盾构机问世，德国硬气的日子也就到头了，是人都知，只要被中国攻克的技术，在国际上，其他国家就没有价格优势。印度进口盾构机还未用就先甩锅毕竟每个国家的钱都不是大风吹来的，在印度货比三家之后，最终选择了中国盾构机。很快，中国在2020年3月就已完成制造，送往印度。但是又重又高的盾构机，运送也是一件难题。既然不能整机运送，只能拆分，这个时候印度又开始“作妖”，找来了英国专家检查质量问题，不过真金不怕火炼，我们的机器质量完全过关。一百多个零件，13辆超级大货车浩浩荡荡地来到印度孟买。按理说，机器运到了印度，我们的工程师是要帮他们组装完成，才算完整交付。谁知，当运到印度时表示：机器已交付，你们可以回去了，组装那么简单的事就交给印度专家吧！印度的内心是：花了重金买下的机器，想在组装的过程中偷学中国技术。不过，事实也证明，印度太高估他们的实力了！印度专家对着这些零件捣鼓了几个月，一直都无法拼装，零件还是那一堆零件。别说偷技术了，拼装都成大问题。

装机不成便甩锅，印度方面表示：盾构机零件材质的问题，不然怎么会拼装不成功！但是别忘了，你之前可是有找过英国专家帮你把关的，而且中国又不单单只出口印度一个国家。2016年，新加坡从购买了10台盾构机用于地铁建设；2017年，俄罗斯购买中国5台盾构机；2019年，中国出口非洲首台盾构机；2019年，土耳其伊斯米尔市修建地铁，采用的也是中国盾构机。为什么他们都没说质量有问题，反倒印度却挑起了刺，其实还是“面子”在作怪。最后，

向印度出口盾构机，如今中印边境的天然防线，被印度挖穿了

印度方面只能拉下脸请求我们派几个专家过去帮他们解决问题。但是好巧不巧，疫情严重再加上中印边境紧张，根本拿不到让中国工程师入境印度的许可。

你看这是闹的，印度还是改改夜郎自大的毛病，放下身段，多多学习，才能改掉“万国造”的局面！

印度网上有消息称，印军挖穿了藏南地区达旺通向色拉山口的隧道。相关照片和视频，在互联网上广泛传播。不过据发布者称，这些证明印度挖穿隧道的照片和视频，已经是4个月前，也就是今年1月份拍摄的，当时就已经基本竣工。

　　事实上，色拉山口在当年的对印反击战中曾经大放异彩，印度在此地被我军打出了教科书级别的穿插包围战术，该地也因此为外界所熟知。因为山脚到山口的海拔落差极大，达到了2千米的地步，这块地方被誉为一条中印边境的天然防线，守军能够居高临下防守，而攻防需要艰难的仰攻。

　　但是换个角度来看，这种地形导致了守军的补给特别困难，尤其是在和平时期，每年封山的大雪，都是对守军生命的一次考验。在当年对印反击战之后，我们主动后撤，放弃了这条防线，也是后勤能力实在难以为继，不能让我们的战士白白牺牲。而到如今，无人机技术的发展、远程制导技术的进步，这种地形优势对我方来说已经微乎其微，也就没有再反复和印度抢这个地方，不如让这里成为印军每年消耗大量人命和物力的“伤口”。

　　在过去的几十年里，印度不止一次想要在达旺修路，但是一方面是基建能力和内部贪腐问题，另一方面，也是缺少专业的工程机械。而这一切在3年里迅速改变了。在2020年中印边境流血冲突的前几个月，印度先后从我国进口了8台应用场景不同的盾构机。其中一台直径达到12.19米。当时国内还有人笑话，印度人买来这些盾构机不会装，还要花钱请中国工程师去帮他们装。

　　虽然印度没有对外声称，用的是不是中国的盾构机，但实际上这种级别的工程，使用盾构机是必然的。

　　坦率的说，在这次印度“旺达-色拉山口”隧道的竣工，印军在中国西南边境的威胁程度，将彻底改变。这条隧道全长2500多米，除主隧道外，还有一条980米和1200米的引路。以战时状况来说，相比于以前，印度利用这条隧道可以直接调动部队、装备等，抵达前线，又可以避开中国卫星监控的优势。本身有山体做掩护，我军很难在第一时间注意到印度的战略意图。对于一向喜欢偷袭、不宣而战的印度军队来说，这条隧道将极大增强自己在中印边境的战略优势。可以说，长久以来在我国边境地区的印度隐患，如今正在借着中美博弈的窗口期，快速成型。
