ABSTRACT:
Horizontal foraminous piping is placed in non-cohesive subsoil by means of an upright engaged disengageably at its bottom end to the top end of an open-ended hollow upright stanchion. Fluid jetted into the top end of the placement pipe and out of the bottom end of the stanchion to fluidize subjacent subsoil enables the pipe to be pressed downward until the stanchion reaches a desired depth. With an end of the cable attached thereto, winding up of the cable draws the foraminous piping to the stanchion, while fluid jetted from the horizontal foraminous piping downward onto and into subjacent subsoil to fluidize it enables the piping to move down into and laterally within the subsoil, for attachment to the stanchion. The placement pipe is disengaged and removed--but may be reattached to facilitate subsequent removal of the stanchion and the piping, usually with fluidizing flow from the piping into adjacent subsoil.
