China's independent research and development of the world's smallest roadheader was born in Zhengzhou
In recent years, the world's smallest hard rock boring machine has China's own R & D, and has been successfully offline. The birth of this kind of tunneling machine with independent property rights indicates that the development and industrialization level of the minimum roadheader in our country has reached the advanced level in the world.
China Railway Equipment Group adopts a new design, which makes the cutter plate strength high, installation accuracy higher, and will not occur welding deformation problem. Dozens of new technologies have greatly enhanced the rock breaking ability and safety factor of roadheader.
It is reported that the application of the large water tunnel in Lebanon Beirut and transportation pipeline construction project of a total of two machines, the value of 120 million yuan. The two roadheader will be assembled in Zhengzhou and expected to be delivered in March this year. This is China's own brand rock tunneling machine exported to Europe for the first time, for China's engineering equipment and international capacity cooperation to add an important pen. With the implementation of China's "The Belt and Road" strategy, the cooperation of the two open Chinese rock boring machine to enter the European market door.
Hard rock boring machine China iron equipment group independently developed the excavation diameter of 3.53 meters, assembled to reach a total length of 235 meters, is currently China's independent research and development made the world's smallest diameter hard rock boring machine, due to the smaller space layout of millions of parts, the internal structure is more complex, design development and manufacturing difficulty hitherto unknown.
The hard rock boring machine will be purchased by German company and will be applied to the construction project of Beirut water supply tunnel and transportation pipeline project in Lebanon. It will be developed for complex geological conditions.
China Railway Equipment Group Design Institute deputy chief engineer He Fei said: "as a tunnel boring machine, are now inclined to polarization, large and small, whether small or large, have great difficulty in design, technology and more difficult. Our large and medium-sized is already mature, this equipment fills the small series and miniaturization series of blank, let the Chinese equipment going out has a broader space."
China's construction machinery is now thinking of internationalization level side by side, more and more products to the world, has been recognized around the world, for enterprises "going out" paved the way better.
