Report from our correspondent (reporter Yu Lihua correspondent Liu Yang) on October 29th morning 8 when, the new Hangzhou train station steel structure built by Chaofeng steel structure, a area of about 4600 square meters, 680 ton truss member is slowly raised, this is also the entire station project of steel structure construction monomer to improve component, to 11 noon, member to be hoisted into place.
Member of the promotion: "fish eye" structure of 12~15/S~U axis, North South span of 78 meters, the West span 60 meters, weight 680 tons. This section contains the 12~15/U axis, U axis north south to East truss cantilever truss, and the S~U/12~15 axis "fish eye" canopy structure, its structure is the outer ring three anisotropic elliptic ring truss structure, intermediate fisheye structure using double tube structure, the "fish eye" truss structure system is complex, bar variety, assembled on the ground level when using up to 1 and a half months, on October 28th afternoon withholding bodiless frame, October 29th officially lifting in place, in October 30th launched a full butt welding. Lifting equipment used for the 10 lifting machines, control pump station 4, the successful completion of a range of the most complex, the most difficult of steel structure, the largest, for subsequent SU axis elevated layer construction operation, at the same time, all over the East plaza.
