The first shield tunnel boring machine in Gansu is fully manufactured by itself      

3 2015 26, China Construction Investment Equipment Manufacturing Co., known as the equipment manufacturing industry in the field of mechanical engineering "aircraft carrier" shield tunneling machine "yellow one" in Maryland official line, before being transported to the southern city subway construction project. According to the relevant personnel, the product from the preparation of shield machine to the product officially off the line for 5 years, the success of the shield machine will be Gansu in the field of equipment manufacturing industry construction machinery heavyweight strength embodiment.

"The shield" is called the equipment manufacturing industry in the field of mechanical engineering "aircraft carrier", not only because of its huge volume, it is the industry related categories most, highest tech products, is the most commonly used in the world, the subway tunnel excavation equipment. For a long time, the domestic "shield machine" mainly to buy foreign technology, domestic manufacturing based.

In Gansu construction investment equipment manufacturing company limited production workshop to see, this 89 meters long "huge monster" towering place. Labeled "Northwest first" and "completely independent intellectual property rights" label this "shield" more of a sense of mystery, the site has a lot of staff and invited representatives of the participants have pulled out a mobile phone with a photo.

According to the introduction, "the Yellow River No. 1" shield tunnel boring machine excavation diameter is 6.29 meters, the excavation speed is 8 centimeters / minute. The lattice mosaic (London) international technology company organizes the domestic and foreign first-class talent overall combined design of the "shield", for the global procurement of spare parts, after Gansu construction investment equipment manufacturing company strictly according to ISO international standards of production, manufacturing, assembly and debugging.

Compared to the previous excavation, the "shield" safe excavation, tunneling speed, low labor intensity of construction; does not affect the ground transportation and facilities, while not affecting the underground pipelines and other facilities; when crossing the river does not affect shipping, rain and other weather conditions, the seasonal effect is not affected by construction, no noise and disturbance in construction; in the loose aquifer in deep buried long tunnel construction often has the technical and economic aspects of the many advantages of superiority, can be increased by 8 - 10 times the subway excavation effect.

Superior performance in similar products outstanding, completely independent intellectual property rights become more proud of the Chinese people. Relevant industry experts said, the products not only fill the blank in the northwest, the formation of a more domestic "shield" manufacturing, north, northwest three Tunan version of new pattern of separation.
