Slurry Displacement Piles - California
A slurry displacement pile is a Cast-In-Drilled-Hole (CIDH) pile introduced into the excavation concurrently with the drilling operation. The drilling fluid, also referred to as slurry or drilling slurry, is used to prevent caving of unstable ground formations and intrusion of groundwater into the drilled hole. The drilling slurry remainsPVC U-tube Drilling and Completion Technology in The drilling technology of wells using PVC-U tubing is similar to that of normal well drilling processes. The choice of the drilling method depends on the drill equipment and geological conditions. Compared to steel wells, PVC-U wells need larger space between the bore-hole and well casing.
