<p>An installation method (figs. 2-7) for assembling fluid impermeable barrier members (1, 501, 101) in the ground to form a hazardous waste containment system (fig. 8) using a series of guide box assemblies (figs. 2 and 4), which can be easily assembled and disassembled and are placed in an excavation fully assembled with their exterior walls preferably spaced from the side walls of the excavation, their interiors providing a dirt-free, temporary, isolated work space for the insertion and interconnection of the barrier members. After the barrier members have been inserted and interconnected, the guide boxes are generally removed in association with back-filling of the excavation. The barrier members include barrier-to-barrier edge seals (508, 108) each having 'Y' shaped seals at its opposed ends. A 'pass-through' (P'/2901; figs. 14-16) may be included in a barrier member and associated guide box for controlled removal of fluids from the contained area (G) to an on-site treatment area (E).</p> |
