Installing Wickdrains
Installing AMERDRAIN vertical drains
AMERDRAIN vertical drains may be installed employing either vibratory of static crowd methods. In either case the drain is enclosed in a tubular steel mandrel of small cross-sectional area (usually 2 x 5 inches). A small steel anchor plate is attached to the wick at the bottom of the mandrel. The mandrel is then driven into the soil either with a static crowd or vibratory rig. When the design depth is reached, the mandrel is extracted. The anchor plate retains the drain in the soil. When the mandrel is fully extracted, the drain is cut off, a new anchor plate is installed and the process begins again.
