| description | The invention discloses a pipeline trenchless laser cutting updating device and an updating method thereof. The problems that in a blade type pipeline cutting device in the prior art, a blade is prone to being damaged, and a cutter is difficult to replace are solved. The pipeline non-excavation laser cutting updating device comprises a traction system arranged in a second working well, a laser cutting mechanism and an expansion jacking mechanism, the laser cutting mechanism and the expansion jacking mechanism start from a first working well and are connected front and back, a dragging device for dragging a new pipeline is arranged on the rear portion of the expansion jacking mechanism, and under the action of the traction system, the laser cutting mechanism and the expansion jacking mechanism are driven by the traction system. The laser cutting mechanism, the expansion jacking mechanism and the dragging device move in the old pipeline and conduct laser cutting of the old pipeline, expansion of the old pipelin |
