Slurry Line

Last updated: May 3, 2018

What Does Slurry Line Mean?

A slurry line is a series of pipes or hoses that transport the drilling mud (suspension fluid) from the face of a tunnel excavation, via discharge pumps, to a separation system at the ground surface. The drilling fluid is then recycled and pumped back to the cutting head to facilitate further advancement of the drill.

Trenchlesspedia Explains Slurry Line

Slurry lines are an essential component of the microtunnelling process. For the drill to advance, drilling fluid is necessary to suspend the drill cuttings to carry them to the surface and also lubricate the cutting head. The system of slurry lines helps to transport the fluid to the separation unit above ground and back to the cutting head to be reused.

Drill cuttings are sometimes passed through a crushing unit prior to entering the slurry line to prevent the line from being blocked by larger particles.
