Abstract
A membrane-lined wall for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.
Claims20
A method of forming a membrane-lined wall, comprising:
- excavating a trench, the trench having two sides, a bottom, and a length;
- positioning a roll of a liner above the trench, such that an axis of the roll is oriented along the length of the trench;
- positioning an edge of the liner above the trench such that the edge is oriented along the length of the trench;
- forcing a portion of the liner between the edge and the roll into the trench such that the liner is supplied from the roll and extends into the trench to form a continuous, seamless barrier between the two sides and the bottom of the trench and an interior portion of the liner;
- installing a reinforcement mat within the interior portion of the liner, the reinforcement mat having a length aligned with the length of the trench, and having a height aligned with the two sides of the trench;
- and
- filling at least part of the interior portion of the liner with a cementitious material that surrounds the reinforcement mat within the interior portion of the liner;
- wherein a weight of the cementitious material forces the liner into contact with the sides of the trench;
- and
- allowing the cementitious material to harden.
