To successfully translate and assemble shield in narrow construction site in the urban central areas, a case study is conducted on the shaft E42 to Chebei station section of the Phase II of Guangzhou metro line 13, and the preparation work before the translation of the shield body and the rear supporting equipment trolley and a shield translation device are discussed. Then the method of assembling the shield in the main line tunnel after rapid translation of the shield body through the horizontal passage is analyzed. Additionally, the construction method of shield launching and advancing in blind tunnel is examined. The shield translation device developed successfully addresses issues, such as longdistance translation of shield body and rear supporting equipment, shield assembly in mined tunnel, shield launching in blind hole without negative rings or electric vehicles, and propulsion by double battery vehicles. This accelerates the horizontal movement speed of the shield, saves the construction costs, and achieves good construction results.
