| Abstract: | The construction scheme of a highway bridge in Ho Chi Minh City of Viet Nam is introduced. The bridge is not a large one, but it is characterized by a clever move of framework installation. Its construction plan adopted floating method, using natural conditions of tidal level changes. On the basis of accurate calculation, adopting existing rotation bearing of tower crane to realize rotation and positioning of steel framework during installation to surmount the limit of geographic position from the riverbed. Practice shows that floating installation is a method of saving man-hour and time, and the one of safety and economy. |
