| Abstract: | For mobile mould frameworks through a bridge, the cast-in-place box girder construction process is line production, and operational cycle time of every girder is about 15 days. From the point of optimizing the construction technique to cut down the construction time, the technologies of box girder steel framework integral lifting technology was pointed out, which realized reinforced bar framework installation at the same time with other synchro working procedure, and the time was shorten 3 days or so. The technology is a good complementarity to the cast-in-place construction method of mobile framework, and can raise the efficiency of construction. |
