ABSTRACT:
A pair of spaced walls which may be formed from corrugated metal sheets are joined together with a bottom plate being attached to the edges of the walls to form a box-like structure. A drive shoe formed by a pair of plates may be attached to the bottom of the structure. A sonic oscillator is attached to the top edges of the structure and sonic energy, preferably at a frequency which causes resonant standing wave vibration of the box-like structure, is applied to such structure so as to drive it into the ground. Successive sections of similar box-like structures are driven into the ground in end to end overlapping relationship to form an elongated box structure installed in the soil. This structure is employed to provide a barrier against the migration of soil pollutants. Further, soil samples can be taken from the area contained by the box-like structure to evaluate the effectiveness of the barrier provided by the first wall. The device can also be utilized as a contaminant monitor by providing perforations in the first wall to collect samples of liquid for evaluation by a contaminant monitor.
