[0002] Most of the existing liquids and gases are transported over long distances using buried pipelines. As the use time increases, the inner walls of these existing pipelines are bound to become scaled, corroded or perforated, so they need to be cleaned, and in serious cases they need to be dismantled and replaced. At present, the method of full-line excavation and replacement is often used for buried pipelines with severe corrosion.

[0003] At present, in order to improve the efficiency of dismantling existing waste pipes by dismantling devices, a Chinese patent with prior art publication number CN213532423U discloses a waste oil pipe dismantling device.
