| Abstract: | Owing to the fact that the piers of the Daijiapo Bridge of Contracted Section C3 of the Ya＇an-Lugu Expressway are very tall,the construction of the cover beams uses the supporting trusses as their scaffolding.Upon the basis of analyzing the forces loaded,the supporting truss uses 8 32-b channels,which are assembled into two truss pieces,at both the top and bottom of which two 32-b channels are butt welded and used respectively as the top and bottom longitudinal beams,which are diagonally connected with two butt-welded 16-a channels.Such design can ensure the safety of the truss structures and meet the requirements of the construction.The design and construction of the supporting trusses for tall piers and the long cover beams are introduced in the paper,which may serve as a useful reference for the construction of other similar projects. |
