The invention discloses a hard rock pipeline shield jacking
machine and a construction technology thereof, and relates to the field of pipeline shield jacking machines, the hard rock pipeline shield jacking
machine comprises a
pipe jacking
machine body and a shield
tail shield, a propelling oil cylinder is fixedly installed between the
pipe jacking machine body and the shield
tail shield, and a cutter head is installed on one side of the shield
tail shield. A synchronous belt is used for driving a second rotating rod to rotate, when a
cam at the top of the second rotating rod exerts acting force on a pushing plate to enable a movable frame to start to slide, then the movable frame is controlled to swing through the synergistic effect of a driving rod and a protruding plate, and through the series of operation, movement of a movable
tool bit is accurately controlled; under the synergistic effect of the
cam and a series of transmission mechanisms, the movable cutter head can swing back and forth in a circular arc shape while the cutter head rotates, so that the
cutting depth and breadth are increased, the
shield tunneling efficiency is improved, and the adaptability of the top
shield machine to different complex geological conditions is enhanced.
