China heavy shield machine explodes mines overseas. What is this?

In ancient times, China was revered as a heavenly kingdom by neighboring countries. Economic capacity and technological development are far ahead of neighboring countries. Although China suffered setbacks and hardships in modern times, it lagged behind the whole world.

However, with the continuous development of science and technology, the emergence of high-quality talents and the constant stability and consolidation of economic strength, the comprehensive strength of the country has been continuously improved, and China has a broader stage and space in the world. China's power is gradually revealed, which makes people all over the world respect China and admire China more and more.

China, which has become a world power, has attracted the attention of foreign scientists with the continuous improvement of its scientific and technological strength. A heavy tool recently developed by China caused a sensation in foreign markets.

It is the birth of shield machine! Its existence makes? Made in China? These four words once again have the opportunity to be noticed and confirmed in the world.

Let us have a deeper understanding of how the weapons of China, a very important big country, shine brilliantly on the world stage.

The birth of shield machine

Our popular scientific name of shield machine is shield tunnel boring machine. It is a professional construction machine for tunnel excavation, and it is the construction equipment for workers to dig tunnels by shield method.

Shield machine is the most advanced mechanical tool for tunnel excavation in modern times. It adopts light energy, machinery, electric energy, liquid sensing and information technology as its main application methods, and its main application function is to dig and cut soil. It is guaranteed to be used in railway, subway, highway, municipal, hydropower and other tunnel projects under the fastest, most convenient and extremely safe conditions.

The original shield machine was born in Britain, and it has been developed and deeply studied in Germany and Japan. The most famous ones are Mitsubishi Heavy Industries and Kawasaki Heavy Industries in Japan, herrick Company in Germany, Vettel Company and other most advanced mechanical R&D companies in the world.

This is because these advanced foreign machinery companies constantly encourage and urge China to independently develop domestic shield machines. In the end, China lived up to expectations and finally had its own shield machine manufacturing factory, which caused a very fierce response all over the world.

According to the current forms of shield machines in China, shield tunnel boring machines in China can be roughly divided into hand-dug shield, extrusion shield, semi-mechanical shield and mechanical shield.

No matter what kind of shield machine, its basic working principle is the same, that is, the construction theory of excavating soil by using a cylindrical steel member to advance along a fixed line in the tunnel.

These cylindrical steel members are a kind of protective structure in the form of shield, which can not only bear the earth pressure, but also effectively avoid the surrounding landslides or groundwater emergencies, and have a great degree of safety guarantee for construction.

Moreover, the shield machine provides the fastest way for construction. It turns out that it takes about four or five years for a tunnel to be completed from the start of construction, but a large tunnel can be completely completed in five or six months by using shield machines for tunnel construction.

Looking at the types and characteristics of shield machines, we can imagine how important shield machines are to the development and economic construction of a country.

China shield machine is popular overseas.

Recently, on a video website, there was a video recording the process of shield machine exported from iron equipment from tiny parts to the final assembly of the whole machine, which instantly became the hottest video on video platforms at home and abroad.

Many netizens from Singapore have left messages under the video: Singapore's technology is so developed, why can't it make such advanced machinery? Compared with backward technology in China, it's amazing that such a large-scale advanced machinery has been made! China used to learn from us, but now it's our turn to learn from China. ?

Many foreign netizens replied:? Although many western developed countries try their best to curb the development of China's technology and suppress China's advanced technology. However, it is impossible for hardworking and intelligent China people to give up easily. ?

Even many netizens expressed their desire to praise China with both hands. China is a manufacturing superpower, an excellent and wonderful country, and the people of China are an example worthy of admiration and learning. I believe that China will build a better world in the near future.

Third, it was created in China and made in China.

Relying on its own strength, China has been getting rid of the knowledge oppression and technical imprisonment given to us by foreign countries, creating a development path and prospects for China.

From 2065438 to September 2008, China independently designed and developed the largest diameter slurry balance shield machine. Because the birth of this shield machine marks that the design and manufacture of shield machine in China has advanced to the world, and China's R&D technology and development capability have entered the forefront of the world.

Moreover, under the favorable conditions of the continuous development of China's political diplomacy and economy and trade, China's shield machine export situation is very good.

According to relevant data, in 20 13, the number of shield machines exported in China was 90, and the number imported was 30. Until 20 18, the number of shield machines exported by China was as high as 127, and only 9 foreign shield machines were imported in the same year.

We export more and more, and import less and less, so we can see that the shield machine in China can meet the needs of domestic engineering construction.

According to the latest data, our own domestic shield machines used in construction account for more than 90% of all shield machines in China, and our shield machines sold abroad account for two thirds of the total.

The advanced technology monopolized by foreign countries for a century was thus broken by China in just a few years.

Recently, news reports said that in April of 20 19, China shield machine successfully entered the European market. During the construction of the Paris Metro 16 line, we designed and manufactured two large-diameter EPB shield machines in China, and became the first shield machine enterprise in France to cooperate with foreign countries by meeting the high standards, high positioning and high standards of France.

This cooperation between China and China means that French shield machine technology has entered the top high-end market in China, which has directly and effectively promoted the development of China-EU cooperation.

Fourth, the bright future of China.

Thanks to the hard work of artisans in China, China stepped into the front of the world, and China can achieve today's achievements. More importantly, these front-line R&D scientists and technicians are constantly under pressure from the international community to China, facing great difficulties and setbacks, and need to constantly explore and develop core technologies and knowledge theories. It is because of their hard work that a powerful China has been made.

Lead the weak and poor countries in the world to keep advancing and developing. With the changes of history and the development of technology, China is no longer the weak China in the past, but its light is gradually blooming on the world stage, attracting the attention of the whole world. I believe that in the near future, China will be famous as a creative power.
