Pipeline replacement device is widened in broken of non-excavation

Technical Field

The utility model relates to a field is changed to the underground piping, specifically is a pipeline is changed to non-excavation breakage widening device.

Background

Various pipes buried underground inevitably suffer wear and tear, and therefore must be replaced at intervals. The pipe crushing or splitting method is a pipe updating method which adopts pipe crushing or splitting equipment to crush or split an old pipe from the inside, extrudes fragments of the old pipe into surrounding soil to form pipe holes, and synchronously pulls in a new pipe (with the same diameter or larger diameter).

Devices and techniques are known for pulling the device through a pipe by means of a wire, chain or other pulling device. The traction device may break under the force of the traction device during operation, leaving the device in the ground. Furthermore, if the device encounters an obstacle, the obstacle may jam the device. In this case, the underground pipe may be clogged to cause damage. Known devices and techniques can obstruct existing underground pipes, thereby making the fluid inside the pipes unable to pass through.

Known trenchless replacement apparatus and methods require the use of relatively long, relatively rigid tools and the apparatus cannot follow existing underground piping to make turns or bends.

Known devices, mostly by breaking existing underground pipes, make room for new pipes. However, some types of polymeric tubes stretch or expand when using these devices, rather than break. Such polymer tubing must be cut to make room for the new tubing.
