Construction of beam arch combination bridge
After incremental launching of continuous box beam,
the steel tube was constructed on the top of deck
system.
Bailey girder trusses were used for the temporary
support system, and the steel tube was rotated
vertically for the main arch ring closure.
Concrete was placed in the steel tube using a
concrete pump machine, as shown in Figure 27.
The main arch ring and continuous box beam were
connected by 28 suspenders, each one was composed
by 18no. 7 strand 7mm parallel wires with 4900 kN
initial tension force.
Figure 27: Main arch bridge construction process
After concrete filled steel tube main arch ring was
completed, each suspender was tensioned to design
force, causing the box beam to lift up and disconnect
from the construction temporary piers, as shown in
Figure 28.
