No. 1 in the world! China's shield technology shows the world that China's technology is leading the world

At present, China has great influence in the world, which also comes from the development of our country. Let the world see that China's technology is leading the world. China has not only developed rapidly, but also actively helped other countries to develop infrastructure. China's infrastructure construction can be regarded as world-class. So having a very aggressive nickname of "infrastructure maniac" infrastructure is not to say that you are ahead of the others if you build more buildings. It depends on strong strength and advanced technology.
For example; The shield technology in China is a powerful technology to support construction. Tunnel construction using shield technology has the characteristics of high automation, labor saving, fast construction speed, one-time tunneling, free from the influence of climate, controlled ground settlement during excavation, reduced impact on ground buildings, and no impact on surface traffic during underwater excavation. In the case of long tunnel line and large buried depth, It is more economical and reasonable to use shield technology for construction.
The shield machine, full name of the shield tunneling machine, is a special engineering machine for tunneling. The modern shield tunneling machine integrates optical, mechanical, electrical, hydraulic, sensing and information technology. It has the functions of excavating and cutting soil, transporting soil ballast, assembling tunnel lining, measuring and guiding deviation correction, and involves geological, civil, mechanical, mechanical, hydraulic, electrical, control, measurement and other disciplines and technologies, In addition, it is necessary to carry out "tailor-made" design and manufacture according to different geological conditions, which requires high reliability. Shield tunneling machines have been widely used in subway, railway, highway, municipal, hydropower and other tunnel projects.
It is not easy to be the first in the world. First of all, we have the world's first technology. Then came the first projects in the world, and some were overtaking projects in the corners. Originally, it is the leading train technology in Europe and America, and Japan is also very advanced. Now, China is far ahead of other countries in the world, and the speed of China's maglev train is the first in the world. There are more than one science and technology that ranks first in the world, and the number of high-tech patents applied by foreign countries in the United Nations is also the first in the world. With the rapid development of our country, more directions will definitely lead the world. Thank you to our scientists and scientific researchers of various professions. With the joint efforts of our people, we will be the first in all fields.
