when the length of the pipeline to be replaced is greater than the distance between the front and rear upright posts, the old pipeline disassembled at S2 is obliquely arranged, and the outer end of the old pipeline is arranged between the front and rear upright posts and close to the upright posts; s4, the longitudinal moving rollers on the supporting blocks rotate to drive the outer end of the old pipeline to move longitudinally outwards, and when the inner end of the old pipeline moves to a position between the front upright post and the rear upright post, the transverse moving rollers on the supporting blocks rotate to adjust the posture of the old pipeline, so that the old pipeline is completely supported on the supporting blocks; s6, one end of the new pipeline is firstly supported on the supporting block, the traversing roller on the supporting block rotates to drive one end of the new pipeline into the pipeline rack, then the longitudinally-moving roller on the supporting block rotates to drive the new pipeline to longitudinally move so that the other end of the new pipeline also moves between the front upright post and the rear upright post, the new pipeline is completely supported on the supporting block, and then the traversing roller rotates to drive the new pipeline to inwardly move and adjust the posture.
