ABSTRACT:
A slurry wall lining system comprises a liner and a liner dispenser having a guide, an anchor, a support line, weights and fasteners. The liner dispenser preferably holds a liner in a rolled up position above the trench on rollers for insertion into the trench. The guide is preferably attached to the dispenser and can be angled to extend down into the trench. The liner is unrolled initially in a vertical direction down into the trench at a rate about equal to the movement of the dispenser along the trench. The liner then passes around the guide into a horizontal orientation in the trench. In the preferred embodiment, the weights pull the liner downward about the guide and secure one edge of the liner near the bottom of the trench. The fasteners, support line and anchor to hold the other edge of the liner along the top of the trench. The preferred method of the present invention comprises the steps of: excavating a trench; filling the trench with slurry and maintaining the slurry at predetermined level as the trench is excavated; inserting a lining into the trench by attaching one end of the lining at the beginning of the trench and unrolling the lining into the trench as the roll is moved along the trench; and backfilling the trench with selected materials on one or both sides of the liner.
