LARGE SPAN GRID SEGMENT ACCUMULATION IMPROVEMENT CONSTRUCTION TECHNOLOGY
For the T3 terminal project of Changsha Airport,the overall construction idea of C finger gallery,the floor assembly scheme,the division scheme of construction section,the layout scheme of lifting point,the lifting measures of cantilever grid,the selection of lifting cable,and the design scheme of lifting rod are studied.The first,second and third grids of the construction section are assembled from the middle to both sides through the ground,+8.300 m floor and+14.900 m floor respectively.The construction technology of the construction section is lifted by block,and the second frame of the construction section and the overall improvement.The results show that it can coordinate the problems of multiple processes and improve the site construction efficiency.
