A BRIDGE DECK LIFT-LAUNCHING CONTRUCTION METHOD AND A LIFT-LAUNCHING DEVICE FOR THE SAME

摘要

PURPOSE: A lift-launching method of a bridge deck and a lift-launching system therefor are provided to accurately install a bridge deck on the tops of piers by lifting the bridge deck using a lift device and horizontally moving the lifted bridge deck. CONSTITUTION: A lift-launching system(100) of a bridge deck comprises multiple lift devices(110), ground rails(125,126), first cars(121,122) for transferring a bridge deck on the ground, upper rails(135,136), and second cars for transferring a bridge deck on the upper rails. The lift devices are fixed to the ground and lift up a bridge deck(10). The ground rails are installed on the ground. The first cars are slid on the ground rails, and the heights of the first cars are adjusted by a hydraulic device. The upper rails are installed on piers(210,220). The second cars are slid on the upper rails.
