China Construction machinery information

Guide: on December 18, the first shield machine locally produced in Nanning was officially offline, which will promote Nanning Metro Line 1 to enter the accelerated construction stage, and also means that Nanning rail transit shield machines have been locally manufactured. Nanning Gaomu front-end equipment industry has embarked on a new starting point. According to the relevant person of Nanning railway company

on December 18, the first shield machine locally produced in Nanning was officially offline, which will promote the accelerated construction of Nanning Metro Line 1, and also means that Nanning rail transit shield machines have been locally manufactured. Nanning's high-end equipment industry has embarked on a new starting point

according to the relevant person of Nanning rail company, shield machine is a special engineering machine for tunneling, which is widely used in subway, railway, highway, municipal, hydropower and other tunnel projects. As the most complex underground engineering high-end equipment, it integrates advanced technologies such as machinery, electricity, hydraulics and automatic control. It is the most cutting-edge technology integration of advanced mechanical design, manufacturing technology and underground engineering construction technology

"Zhongguang rail transit No.1 shield machine" is a kind of equipment specially made for Nanning Metro Line 1 by China Railway Engineering Equipment Group Co., Ltd., Nanning Guangfa Heavy Industry Group Co., Ltd. and Nanning Rail Transit Co., Ltd. based on the platform of the leading enterprise of Nanning railway to train Zhuang Daning China Railway Guangfa Rail Transit Equipment Co., Ltd. and according to the complex underground geological conditions in Nanning. The successful offline of "Zhongguang railway, such as No. 1 shield machine" marks that Nanning has achieved localized production of shield machines and made up for the gap in the shield manufacturing industry in Nanning

according to the Nanning rail transit line plan, in the next 20 years, Nanning will successively build eight subway lines, with a total operating mileage of 252 kilometers. As an important high-end equipment for the construction of section tunnels in rail transit projects, Nanning rail transit has a great demand for shield machines. Metro Line 1, which has entered the stage of shield tunneling, plans to invest 28 shield machines for every 10% reduction in vehicle weight, and rail transit line 2, which will start construction at the end of the year, is expected to invest at least 8 more shield machines. It is expected that with an additional construction line every 1-2 years after 2015, the demand for the use and maintenance of shield machines will maintain a steady growth trend. The shield machine produced locally in Nanning will greatly promote the construction of Nanning railway

the first shield machine designed and manufactured locally in Nanning. Nanning rail company provided drawings of the internal mechanism of the shield machine. Drawings provided by Nanning railway company
