China's first micro shield line in railway construction 

In September 12th, the first domestic successful offline Mini shield machine in China railway construction, the new equipment will be used in the project of Wuhan cable pipe gallery construction, and filled the domestic self-developed miniature shield machine in the application area of the tunnel blank pipe gallery.

Let's get to know this device first. The equipment is developed, a new model for Wuhan underground pipe gallery project characteristics of the shield machine, its diameter is 3.7m, the length of 85m, can achieve complex geological tunnel construction of single excavation distance of over 10 kilometers, the curve radius is less than 100 meters, the design of the maximum monthly footage of 400 meters, the successful implementation of the mini shield machine in turn, long distance and small diameter pipe gallery application in tunnel engineering, compared with the traditional construction method of tunnel construction, to improve the efficiency to more than 2 times of the working environment and safety of tunnel construction has been greatly improved.

According to the characteristics of tunnel engineering and construction used to clients of the corridor, the railway construction heavy industry developed a new node shield double hinged, screw conveyor, ball joint front buried cutter main control pipeline arrangement, high density and high power single reducer drive, unique room and interactive operating system structure, new technology, fully meet the the tunnel tunnel project "long distance, small turning, high efficiency" construction requirements.

It is understood that the underground pipe gallery is used in underground laying of public power, tunnel communication, water supply, drainage, gas, heat and other municipal pipeline construction, underground pipe gallery not only can effectively solve the problem of repeated ground excavation "road zipper" and so on, can cure "rains that flood" and "urban diseases". Previously, the city railway construction heavy pipe gallery tunnel buried depth, small turning radius, difficult construction characteristics, has successfully developed a rectangular shield machine, pipe jacking machine and other special equipment for the construction of power engineering construction, city gallery.

At present, the underground construction of our country in our country is developing like a raging fire underground hole means that safety is the first, and reliable shield machine is what we rely on, believe that the railway construction heavy Mini shield machine will not disappoint us.
