3) Forming the connections between the long lateral
beams. After hoisting into position, the temporary
bailey girder scaffolds are lifted onto the foot of
three lateral suspenders locating the same row in
order to assemble the lateral beam precast block
(length of 7.4m) between three small frames, as
shown in Figure 13.
The long lateral beam is formed when finishing
the following stages, including welding the joint
reinforcement, casting the concrete in the
connection and tensioning the lateral prestressed
tendons, as shown in Figure 14. 5) Forming the continuous bridge deck system.
When the floating frame system is established,
the precast bridge deck panels will be hoisted
onto the frame, as shown in Figure 16, and the
continuous bridge deck system is formed by
welding the reinforcement between the decks and
casting the joint, as shown in Figure 17.
4) Forming the whole frame. When 23 rows of lateral
beams are in position, the short longitudinal
girders are placed on the bailey scaffolds, and the
total frame is formed by welding the joint
reinforcement, casting the concrete joints and
tensioning the longitudinal prestressed tendons,
as shown in Figure 15.
