Abstract
A combination connector and supporting member for a segmented membrane barrier is disclosed. A tubular connector is joined to one end of a membrane segment along a continuous seam and a second smaller connector, adapted to fit within the tubular connector, is attached to the opposite end of the membrane segment along a second continuous seam. A projection, extending beyond the edge of the membrane segment is adapted to fit within a key or the like for supporting and locating the connectors in a trench.
Claims14
A membrane barrier segment for forming a buried fluid barrier comprising:
- an elongate sheet of impermeable material having first and second ends;
- a first one-piece tubular member connected to said first end along a first continuous seam, said first tubular member having a first outside diameter;
- and
- a second one-piece tubular member connected to said second end along a second continuous seam, said second tubular member characterized by an inner diameter greater than said first outer diameter, and having a slot in a side wall thereof for passing said continuous membrane through, at least said second tubular member having an end portion projecting beyond an edge of said sheet.
A barrier for underground fluid material flow control comprising:
- a trench in the earth having a length extending across the expected polution path;
- a segmented membrane barrier in said trench, said barrier comprising a plurality of membrane segments;
- a first tubular joining member on one end of each of said segments, each of said first joining members comprising a tubular member attached to said segment along a continuous fluid impervious seam;
- said tubular members characterized by a preselected inside dimension;
- a second tubular joining member on the other end of each of said segments, each of said second joining members comprising a tubular member attached to said segment along a continuous fluid impervious seam;
- a slot in a side wall of each of said first tubular joining members adapted to pass said membrane therethrough when said second tubular joining elrments are disposed within said first tubular joining members;
- at least said first tubular joining member having an end portion projecting beyond said membrane segments;
- means in said trench for receiving said projecting portion for locating and supporting said second tubular joining member;
- a fluid impervious sealing material disposed in the space between said first and second tubular joining members.
