How is the prestressed steel bar in the hanging basket method? Is the length of each section of the tension of the prestressing tendons, or tensioned T - shaped steel beam length of prestressed tendons?
I have answered a similar question, which is now available for reference
Repeat the above process, so that the cycle of propulsion, until all of the complete beam segment. Specific recommendations for the cast-in-place prestressed box girder construction materials.
The general construction of prestressed concrete box girder with cantilever hanging basket construction scheme, the box girder hanging basket, formwork, reinforced after installation, concrete pouring, the concrete reaches the design strength value after tensioning the beam segments each segment between the prestressed tendons (tendons connected according to the design of short or long beam the layout of the beam.) after grouting, demolition template
