| Abstract: | Control on assembly quality of wide-span steel structure is difficult and assembly accuracy may be affected.Problems in control on ground assembly accuracy of large-diameter arch tube truss are successfully solved through treatment of assembly site,design of assembly jig,selection of assembly sequence and adoption of new chain steel tube butting device during construction,to pave a solid foundation for smooth development of subsequent construction. |
