FIVE SEGMENTAL BULB-TEE GIRDER FOR A BRIDGE AND IT'S CONSTRUCTIONAL METHOD

摘要

A method for assembling five segmental bulb-tee girders of a bridge is provided to propel and move the girder by installing a trolley on ties and rails at an assembling field and using the trolley and to thereby improve working efficiency and economical property by easily assembling the girders. In a method for assembling five segmental bulb-tee girders of a bridge, a used structure comprises ties installed on an assembling field; gravels layered around the ties; a rail installed at the upper side of the tie; a trolley moved along the rail and formed with wheels at the lower side; a first segmental unit(A) moved and assembled on the trolley and formed on the forefront side; a second segmental unit(B) formed on the rear side of the first segmental unit; a third segmental unit formed on the rear side of the second segmental unit; a fourth segmental unit formed on the rear side of the third segmental unit; a fifth segmental unit formed on the rear side of the fourth segmental unit; and an overturn preventing rope fixing each segmental unit.
