The independently developed slurry shield machine "Yong Jiang", which has the largest diameter of its kind in the world, rolled off the assembly line of Wuxi China Railway Urban Rail Equipment Company on June 20.
The shield machine will be first put into use working on the Boao tunnel project in Hangzhou after being delivered.
The important river-crossing tunnel will link the main urban area of Qianjiang New Town and the sub-center city areas in Hangzhou, and acts as an important component for the preparation of the Hangzhou 2022 Asian Games.
The shield machine is another major breakthrough machine made by Urban Rail Transit Engineering Company of China Railway First Group Company, following the debut of the company's first shield machine China Railway 581 on March 15. According to company representatives, the "Yong Jiang" shield machine has a diameter of 11.7 meters, which makes it world's largest in diametrical terms.
Wuxi China Railway Urban Rail Equipment Company has currently secured nine orders and five potential orders, and has an annual production capacity of 10-15 sets for the machine.
Another large-diameter shield machine, named the "Asian Games", is also set to be used in the Boao tunnel project and will soon begin assembly and commissioning. It is expected that at the end of July, the "China Railway 682" machine will be put into use in the construction of the Wuxi Metro Line 4.
