Main features of hanging basket construction1 can bear the weight of the beam section and construction load:2 stiffness, small deformation;3 lightweight structure, easy to move forward;4 the scope of adaptation is large, and the bottom mould frame is easy to lift, which is suitable for different beam height.
Single total weight of 56.6 tons (excluding side die, die), can be poured a span of 4 meters, weight of 125 tons of reinforced concrete box girder. The hanging basket is manufactured in the factory, and the pre pressure is installed on the site. After checking the safety of the hanging basket and detecting the deflection of the guide beam, the formwork of the box girder, the binding steel bar, the installation of the corrugated pipe and the pouring concrete can be set up. After pouring a pair of beam sections, the prestressed concrete is fixed, and then the hanging basket is moved forward, and the pouring of the next section of the box beam is carried out until the end of the cantilever end.
The so-called hanging basket construction refers to the casting of Large Span Cantilever Beam Bridge, the use of hanging basket method, the local segmental cantilever operation. It does not need to install the bracket and do not use large crane. The hanging basket construction compared with other methods, has the advantages of light structure, simple and convenient, no heavy pressure, etc..
