Abstract
An apparatus for delivering liner material into a trench prevents sidewall collapse in a subsurface water saturated zone, provides for inspection of vertical joints, avoids the necessity for dewatering of an area to be trenched, and provides continuous rolls of liner material which are joined by vertical and horizontal seams to accommodate any length or configuration of placement. To initiate unrolling of a length of liner material, a roll of material is dropped into the installation apparatus which trenches into the subsurface. One end of the liner material is held in place by restraints and hydraulic presses. The roll is then unrolled by trenching backwards, cutting a trench and unfurling the roll in the formed trench.

12. A barrier wall system comprising:
-
a tractor, a cutter assembly mounted on said tractor for digging a trench of a depth up to sixty feet on one side of an area of contaminated soil, a delivery device mounted on said cutter assembly for locating an impermeable liner material placed in said trench in a vertical orientation on said one side of said area of contaminated soil during one pass of said cutter assembly to prevent passage of groundwater, a permeable liner material placed in said trench in a vertical orientation between said area of contaminated soil and said impermeable liner material during another pass of said cutter assembly for allowing flow through of contaminated groundwater, said permeable liner material including treatment materials for treating in situ contaminated water passing therethrough, and a collection pipe buried in the earth between said impermeable liner material and said impermeable liner material for collection of groundwater having passed in a direction from said contaminated soil through said permeable liner material and into said collection pipe, said delivery device being vertically elongated and enclosed for receiving one of said impermeable liner material and said permeable liner material positioned in a vertical orientation in said delivery device with one of the liner materials being initially positioned in and emanating in said single layer from an elongated opening of said delivery device in a same orientation as the one liner material will be positioned in the trench simultaneously dug by said cutter assembly, at least one of said delivery device and said one liner material including a connector for securing a trailing edge of one length of said one liner material to a leading edge of another length of said one liner material with a leak-proof joint, said cutter assembly digging said trench and feeding fill material into said trench simultaneously with unrolling said liner material from said delivery device. - View Dependent Claims (13, 14, 15, 16)
