Flexible arch splicing method for steel trussed beams
The invention provides a flexible arch splicing method for steel trussed beams. The method includes the steps that steel pipe pile temporary piers are erected at the proper positions of side spans and a main span, steel pipe pile temporary supports are arranged on the two longitudinal sides of a middle pier, meanwhile, a middle pier bearing platform and side pier bearing platforms are each provided with a tower crane, all rod pieces of the steel trussed beams are suspended by the tower cranes to a beam conveying trolley, the side span steel trussed beams and the middle span steel trussed beam are symmetrically spliced in a suspended mode through suspended splicing cranes to the pier tops of temporary piers under the main span to be folded, and then arch ribs are folded in a suspended splicing mode on the folded steel trussed beams through long arm cranes. According to the flexible arch splicing method for the steel trussed beams, large-scale construction equipment such as a high tower truss, a cable crane and a gantry crane does not need to be used, the construction equipment investment is lowered, the construction risks are lowered, a plurality of construction procedures can be executed at the same time, the construction efficiency can be effectively improved, and the construction progress can be effectively accelerated; meanwhile, operation in water is reduced as much as possible, the navigation requirement is met, and construction is safe, easy and convenient.
