The advent of China's giant "Pilot" shield machine has attracted widespread attention. As the world's largest diameter shield machine, its emergence has not only caused a sensation in the world, but also has a significant impact on the domestic market pattern.
There are even experts who say: It's the turn of Europe and the United States to be stuck!
The shield machine is an important mechanical equipment used in tunnel engineering construction, and its main role is to excavate and construct tunnels underground. It plays an important role in urban underground transportation, subway, water conservancy engineering and other fields.
In recent years, with the acceleration of urbanization and the increase in demand for infrastructure construction, the shield machine market has shown a rapid growth trend.
The development of this technology has also made great progress, and it is no exaggeration to say that the domestic shield machine has in fact achieved corner overtaking. According to the available information, it has occupied more than 90% of the domestic and international market share of about 65%. However, with the advent of the 2,600-ton "Pilot" shield machine, the subsequent data is even more self-evident.
Maybe when it comes to this, there will still be more netizens who don't understand: what is the shield machine? So, let's explain this problem in detail:
It is a kind of special mechanical equipment used in the construction of underground tunnel engineering, and its role is also very important and diversified.
First, it excavates tunnels in the ground using the cutterhead and the earth pressure around the cutterhead, excavates the underground soil layer and transports it to the surface through a conveyor system. This method can effectively reduce the impact on surface traffic and the surrounding environment, and is one of the main methods of tunnel engineering construction.
Secondly, it can also play a vital role in the construction of urban underground transportation. With the acceleration of urbanization and the increasingly serious congestion of urban traffic, the construction of underground traffic tunnels has become an important means to alleviate traffic pressure. The application of the shield machine can realize the fast, efficient and safe construction of tunnel engineering, and provide a reliable guarantee for the development of urban transportation.
In addition, it can also be used in water conservancy engineering, subway construction, underground pipe gallery construction and other fields. In water conservancy engineering, the shield machine is used for the dredging of the river bed and the dredging of the river channel, and in the subway construction, the subway tunnel can be excavated to connect different areas of the city, and in the construction of underground pipe gallery, it can be used for the laying and maintenance of underground pipelines.
In short, the shield machine does play an important role in various underground projects and makes important contributions to the construction and development of modern cities.
At the same time, we also need to understand the problems of the "Pilot" shield machine:
The shield machine is jointly developed by China Railway Tunnel Bureau and China Railway Engineering Equipment Group, and its cutterhead diameter reaches an astonishing 15.4 meters, the main engine is about 15.8 meters long, the total length is about 128 meters, and the main engine weighs about 2,600 tons. According to such data, it means that China's technical strength in the field of shield machines has indeed reached the world's leading level.
Moreover, the emergence of the "Pilot" shield machine is of great significance to the construction of tunnel engineering in China and even the world.
On the one hand. It will further enhance the international competitiveness of China's shield machine technology, and promote China's shield machine to the world, and realize the leap from "Made in China" to "Made in China". On the other hand, the advent of the giant shield machine will accelerate China's development in the fields of underground transportation and urban construction, and provide strong support for the construction of urban infrastructure.
In this field, the emergence of the "Pilot" shield machine actually represents: to a certain extent, it does bring certain pressure to Europe and the United States, but whether it can be said that it is the turn of Europe and the United States to be "stuck" still needs to be understood from many aspects.
The huge size and advanced technology of the "Pilot" shield machine have greatly improved the production capacity and competitiveness of China's shield machine, posing a certain challenge to the international market. Especially for Europe and the United States and other countries have monopolized the shield machine market for a long time, China's technological breakthroughs and market share growth will indeed have a certain degree of impact.
Secondly, its emergence may also change the international market pattern. With the continuous maturity and breakthrough of China's shield machine technology, China is expected to gradually occupy a dominant position in the international market. This will make Europe and the United States and other countries face more fierce competition, and have to increase technology investment and research and development efforts to improve their competitiveness.
However, it may be too early to say that it is the turn of Europe and the United States to be "stuck".
You must know that developed countries such as Europe and the United States still have strong advantages in shield machine technology and market, and have rich experience and mature technical system.
Although China's shield machine technology is advanced, it still needs time and effort to gain wider recognition and application in the international market. Therefore, in order to truly let Europe and the United States be "stuck", it is necessary to continuously improve its own technical level and market competitiveness, as well as strengthen international cooperation and exchanges, only in this way can we achieve a win-win situation with Europe and the United States and other countries.
