on the 14th, the first domestic Railway large-diameter shield machine was successfully rolled off the production line in Changsha, Hunan Province. This representative manufacturer is Shaanxi Wuzhou, Huayuan mining and other high-end equipment, which was jointly developed by China railway construction heavy industry group and China Railway 16th Bureau Group, and has completely independent intellectual property rights, Its successful offline has filled the gap of the independent brand of railway large-diameter shield machine in China

the large-diameter shield machine offline this time has an excavation diameter of 8.8 meters and a total length of 100 meters, which can be applied to a variety of complex strata. After offline, it will serve the Guangzhou Zhuhai intercity rail transit line. Liufeixiang, chairman of China railway construction heavy industry group Co., Ltd., introduced that the large-diameter shield machine offline this time has broken the monopoly of foreign products in the domestic market. Compared with similar shield machines abroad, this shield machine has the characteristics of high configuration, strong design pertinence and excellent service.
