The lower line of Chengdu shield machine to realize the "wisdom" of the shield machine in China

As we all know, China has always been a big manufacturing country. In order to improve the international competitiveness of manufacturing industry, China has been turning to "intellectual creation" in recent years.

In January 10th, the double shielded full face rock tunnel boring machine (TBM) developed by China was downloaded at the Chengdu base of China Railway Equipment Group, which is also the No. 241st roadheader of China Railway Equipment Group.

Double shield TBM has two driving modes: single shield and double shield. It is suitable for hard rock and soft rock stratum. It can realize the construction of complex geomorphology and deep buried long tunnel which is difficult to realize by traditional drilling and blasting method. It is worth mentioning that the equipment can independently according to the geological conditions, the construction schedule flexible selection of different driving mode, to achieve continuous driving, will be used for drinking water source of Lanzhou city construction project, the construction of tunnel length of 24.4 kilometers and a maximum depth of 918 meters, is expected in January 15th to the project site.

The whole equipment integration technology, hard rock environment efficient rock breaking cutter design, poor geological conditions of emergency treatment design technology has reached the world advanced level, 20%-30% cheaper than imported equipment, marking the shield machine in China has China "wisdom", "Chengdu made" shield machine gradually to the country.

"The design and development of the shield machine is at headquarters, and we are considering the production and manufacture of the plant in Chengdu." China Railway Equipment Group responsible person said, Chengdu metro line 18 is expected to adopt the China railway equipment group independently developed shield machine, related matters are under negotiation. Previously, Chengdu Metro limited liability company has revealed that the 18 line speed and other standards are high, so vehicles, shield machines and so on need to "tailor."

After the transformation and transformation of Chinese manufacturing industry in recent years, manufacturing in China has gradually shifted to "intelligent manufacturing in China", and has gradually become a "smart manufacturing" power in the world. At the same time, it also gave 2015 chance to change the blood of the construction machinery industry.
