Simple introduction of hanging basket construction:1 steel cable-stayed bridge construction, most of the factory welding, transported to the site, with the crane as a whole lifting, or block lifting, in place after the formation of high-strength bolts.2 construction of concrete cable-stayed bridge with cast-in-place and precast assembly and other combinations of construction technology.
After pouring a concrete, such as the strength of the aging period, the tension of a paragraph, and then continue to the next section of constructionSpecific construction process and other prestressed construction process the same
The post tensioned prestressed precast box girder is prefabricated by a prefabricated field or a prefabricated factory, and then transported to the site erection; (2) the post tensioned prestressed cast-in-place box girder is directly poured into the box girder and the prestressed tension on the bridge. Cast in situ prestressed box girder, according to the support structure is different, the full frame pouring box beam and hanging basket construction pouring box beam. The hanging basket construction is the use of suspension facilities, segmental mold hanging and binding steel corrugated pipe, installation, concrete pouring, wearing steel strand, stretching and grouting, the completion of a segmental box girder, a segmental box girder, until the completion of the entire construction segment.
