What Does Slurry Shield Method Mean?
The slurry shield method is used to make a pilot bore using water jets on the closed end of a pipe. As the cutting action is performed by a cutting wheel, the slurry in an isolated chamber maintains face stability and carries out excavated material by matching the pressure at the working face of the excavation. The slurry shield method is best employed in soft, unstable material like sand, gravel or silts, as well as with pressurized ground water or in areas sensitive to ground movement.
