Method for constructing Key segment of bridge

摘要

The present invention relates to a method for constructing bridge segments. The split formwork 55 which is part of the tip of the side span formwork 53 provided for the construction of the side span slab 50 is configured to be detachable from the side span formwork 53. The split formwork 55 separated from the side span formwork 53 is advanced in the state seated on the truss 52 to form a temporary space of the side span connecting segment 60, thereby forming the side span slab 50 and the side span connecting segment ( 60) is constructed continuously. Then, moving the formwork for the center segment 86 assembled on the land to the barge 85, and then lifted and installed in the center discontinuous section (K1) to construct the center connecting segment 70. At this time, the formwork for the central segment 86, the split formwork 55 used in the construction of the side-span connection segment 60 may be used as it is. As described above, according to the present invention, since the divided formwork 55 forming the tip of the side span slab 50 is separated from the side span formwork 53 and used to form the side span connecting segment 60 and the center connecting segment 70. The air is shortened and the side span and center connecting segments are constructed continuously to provide high quality bridges.;Bridge, segment, continuous, construction, formwork
