ABSTRACT:
There is disclosed a method and apparatus for laying small-diameter gas, water pipes or the like precisely in the ground. Small-diameter pilot pipes are first laid in while at the same time, a pilot head is measured and controlled to make its straight advance. Pipes of a larger diameter are then laid in successively, the pipes being led by the pilot pipes. Concurrent with this, excavated earth is discharged through the laid-in pilot pipes.
