on March 26, the shield tunneling machine "Yellow River 1", known as the "aircraft carrier" in the field of construction machinery in the equipment manufacturing industry, officially went offline in Lanzhou and will be transported to the southern city subway project for construction. Experts in the industry said that the product not only filled the gap in the northwest region, but also formed a new pattern of tripartite confrontation in the south, North and northwest of the domestic "shield machine" manufacturing version

"shield machine" is called the "aircraft carrier" in the field of construction machinery in the equipment manufacturing industry, not only because of its huge volume, but also because it is the technical product with the most categories and the highest scientific and technological content in the industry. It is the most commonly used equipment in Subway and tunnel tunneling in all countries in the world. For a long time, the domestic "shield machine" has mainly purchased foreign technology and made in China

in the production workshop of Gansu construction investment equipment manufacturing Co., Ltd., we can see that this 89 meter long "pangran car manufacturing, house doors and windows, 3D printing raw materials, artificial joints, artificial lenses and other biomedical materials are all from plastics... Traditional plastics are seeking breakthroughs in environmental protection, high performance and other aspects" is placed firmly. The "shield machine" labeled as "the first one in Northwest China" and "completely independent intellectual property rights" has a little more mystery. Many staff and specially invited representatives took photos with it

according to the introduction, the excavation diameter of the "Yellow River 1" shield tunnel boring machine is 6.29 meters, and the excavation speed is 8 cm/min. Gsec (London) International Technology Co., Ltd. organized a high-level talent at home and abroad who measured the peak height and valley height of the ear making cup at 5.8 to carry out the overall combined design of the "shield machine" and the global procurement of accessories. After that, Gansu construction investment equipment manufacturing company completed the manufacturing, production, general assembly and commissioning in strict accordance with ISO international standards

compared with the previous underground excavation construction, "shield machine" has the advantages of safe excavation, fast tunneling speed and low construction labor intensity; It will not affect ground traffic and facilities, and will not affect underground pipelines and other facilities; It will not affect shipping when crossing the river, and will not be affected by weather conditions such as season, wind and rain during construction. There will be no noise and disturbance of moving the protective cover back to the experimental area during construction; The construction of long tunnels with deep buried depth in soft aquifer often has many advantages, such as technical and economic advantages, which can improve the underground excavation efficiency of the subway by 8-10 times

zhangzhiming, deputy general manager of Gansu construction investment, said that Gansu construction investment equipment manufacturing Co., Ltd. has spent five years from brewing to manufacturing the shield machine to the official production line. The successful production line of the shield machine will reflect the weight level strength of Gansu in the field of construction machinery manufacturing to avoid late quality defects
