Abstract
An apparatus, method and system for installing water impervious barrier walls underground and particularly in levees. A mobile trailer movably mounted on rails carries upstanding front and rear masts and a carrier bar therebetween that is power driven up and down the masts. Augers mounted on the carrier bar are driven into the levee surface to create overlapping holes of loosened soil. A slurry of cement based grout is pumped through the augers to be mixed with the soil by the rotating, retracting augers to produce a soil-concrete slurry. A following mobile trailer also movably mounted on the rails is moved into position over the wall segment of uncured soil-concrete slurry. The following trailer carries a supply of water impervious membrane. Mechanism on the second trailer inserts the membrane into the soil-concrete slurry to produce a water impervious barrier wall segment. The trailers are sequentially moved along the levee to install a continuous water impervious barrier wall along the levee length.
