What Does Pipe Pulling Mean?

Pipe pulling is a trenchless rehabilitation technique where a new pipe is attached to the old pipe and pulled into the ground as the old pipe is pulled out. This technique uses the route of the existing pipe to prevent the need for further excavation and spoil removal. Pipe pulling is useful for small diameter piping.


Trenchlesspedia Explains Pipe Pulling

Pipe pulling requires an entry pit and an exit pit. Pulling equipment is installed into the exit pit and a chain is threaded through the old pipe to the entry pit. A connector is attached to the chain that presses into the end of the old pipe. The other side of the connector is attached to the new pipe. As the puller is wound up from the exit pit, the connector pushes the old pipe out in front of it while pulling the new pipe in behind it.
