PURPOSE: A caisson lifting lug structure is provided to connect a caisson to a lifting device via a protruding part of a reinforcing bar of the caisson without a separate tie cable. CONSTITUTION: In a caisson lifting lug apparatus, a longitudinal reinforcing bar(130) buried in a concrete caisson wall is coupled to a lifting device(110). The top of the reinforcing bar is protruded from the upper surface of a caisson(200). The protruding reinforcing bar passes through a plurality of reinforcing bar coupling holes formed in the lifting device so that the end is coupled to the lifting device. A cable connecting hole is formed in the middle portion of the lifting device to connect a cable for lifting a caisson. |
