HYDRAULIC JACK EXPANSION-TYPE ROTARY PENETRATION DEVICE FOR CIRCULAR PIPE
A hydraulic jack expansion-type rotary penetration device for a circular pipe comprises: a rotating head which receives torque from the outside; one or more hollow shafts arranged in series downward along the central axis of the rotating head; shaft-connection socket which interconnect the first hollow shaft which is connected to the rotating head with the remaining adjacent hollow shafts, to thereby transmit the torque of the rotating head; and one or more clamp modules which are installed in the hollow shafts and pressed against the inner surface of the circular pipe by hydraulic pressure generated in the rotating head to thereby generate clamping force.
