摘要： A pipe jacking apparatus comprises a shield type tunneling machine equipped with direction adjusting jacks, a tubular body joined to the rear of the shield type tunneling machine, and a thrust jack provided within a thrust pit and thrusting forward a pipe member placed between the shield tunneling machine and the thrust jack, in cooperation with the shield type tunneling machine. The aforesaid tubular body includes a panel therein having output gages for the aforesaid jacks and a mark representing the center of the tubular body, and a TV camera for taking a picture of the panel. This TV camera is connected to a TV receiver provided in a remote control unit. In the aforesaid pit, there is provided an optical unit having a line of collimation directed to a predetermined direction to thrust a pipe, or a light source for light beams. A pipe is driven forward while a discrepancy between the line of collimation or the light beam and the center mark is being eliminated by remote-controlling the outputs of the aforesaid jacks. This apparatus is particularly fit for use in laying a diametrically small sewer pipe in the ground.
