Beijing new airport terminal building is the largest building using isolation technology of the world, the isolation bearings and dampers are used to reduce seismic effect and vibration caused by the subway. Considering the incompleted transportation, complex isolation connection, hoisting difficulties and so on. Some measures such as the tower crane co-used with construction equipment, the way of assembling reinforcement optimized, secondary grouting enforced, locating plate retained, are taken to ensure the large diameter isolation bearing hoisted, isolation bearing special connection completed, the criterion of large section buttresses compactness and smoothness meted. The isolation beating installation method and quality control for installation provide experience for isolation projects using large diameter rubber isolation in the future.
