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.
Claims23
A method, comprising:
- positioning a roll of a liner over one side of a trench having two sides that define an opening to the trench, a bottom and a length, such that an axis of the roll is oriented along the length of the trench;
- suspending and clamping an edge of the liner over the opening of the trench and proximate a side of the trench opposite the roll of the liner such that the edge is oriented along the length of the trench;
- and
- 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.

A method, comprising:
- positioning a roll of a liner over one side of a trench having two sides that define an opening to the trench, a bottom and a length, such that the roll is oriented along the length of the trench, wherein the liner comprises an inner layer adjacent to an interior portion of the trench, and an outer layer adjacent to the two sides and the bottom of the trench;
- suspending and clamping an edge of the liner over the opening of the trench and proximate a side of the trench opposite the roll such that the edge is oriented along the length of the trench;
- and
- 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 the interior portion of the trench;
- wherein the inner layer comprises multiple sections, wherein each section forms an overlap with an adjacent section along a first edge;
- and
- wherein the outer layer comprises multiple sections, wherein each section of the outer layer forms an overlap with an adjacent section of the outer layer along a second edge, and wherein each overlap of the inner layer is spaced apart from each overlap of the outer layer in a direction along the length of the trench.

- forcing, with a lengthwise weight, 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 the interior portion of the trench;
- wherein the inner layer comprises multiple sections, wherein each section forms an overlap with an adjacent section along a first edge;
