Abstract

The specification and drawing figures describe and show one or more improved ditch liners removably assembled into an improved ditch liner system. The improved ditch liner system includes a first liner section and a second liner section. Both liner sections are formed with a plurality of tightly peaked arc-and-ridge corrugations. Also included is a novel and unique overlap connection assembly for removably connecting one liner section to another liner section. In addition, various ways for sealing the overlap connection assembly are included. The interconnected system of improved ditch liner sections may be secured in a ditch by one or more removable rods. This abstract is provided to comply with rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure, but this abstract is not to be used to interpret or limit the scope or meaning of any claim.

Claims (19)

1. A ditch liner system, comprising:

a first liner section formed with a plurality of tightly peaked arc-and-ridge corrugations;

a second liner section formed with a plurality of tightly peaked arc-and-ridge corrugations;

an overlap connection assembly for removably connecting the first liner section and the second liner section; and

means for sealing the overlap connection assembly.

2. A ditch liner system as recited in claim 1 , wherein the first liner section and second liner section are semi-circular in cross-section.

3. A ditch liner system as recited in claim 2 , wherein the first liner section and second liner section are formed with a cross-sectional shape selected from the group of shapes and portions of shapes consisting of trapezoids, ducts, squares, rectangles, parabolas, and triangles.

4. A ditch liner system as recited in claim 1 , wherein the plurality of tightly peaked arc-and-ridge corrugations includes a plurality of substantially semi-circular ducts with opposing edges.

5. A ditch liner system as recited in claim 4 , wherein the plurality of tightly peaked arc-and-ridge corrugations includes a substantially rounded ridge monolithically formed adjacent the opposing edges extending the length of the semi-circular ducts.

6. A ditch liner system as recited in claim 1 , wherein the first liner section and second liner section are formed with a proximal end and a distal end.

7. A ditch liner system as recited in claim 6 , wherein the plurality of tightly peaked arc-and-ridge corrugations extends substantially the length of the first liner section and second liner section between the proximal end and the distal end.

8. A ditch liner system as recited in claim 1 , wherein the overlap connection assembly includes a chambered female extension formed in the proximal end of the first liner section and second liner section.

9. A ditch liner system as recited in claim 8 , wherein the chambered female extension further comprises a channel.

10. A ditch liner system as recited in claim 9 , wherein the overlap connection assembly includes a cup-shaped male extension formed in the distal end of the first liner section and second liner section.

11. A ditch liner system as recited in claim 10 , wherein the cup-shaped male extension further comprises one or more ribs for restricting lateral movement of the cup-shaped male extension within the channel.

12. A ditch liner system as recited in claim 11 , wherein the cup-shaped male extension and the chambered female extension are compressibly connectable.

13. A ditch liner system as recited in claim 1 , wherein the sealing means includes a sealant removably insertable into the channel.

14. A ditch liner system as recited in claim 13 , wherein the sealant is a vulcanized rubber hydrophilic seal.

15. A ditch liner system as recited in claim 1 , wherein the sealing means includes a connector extractably insertable in the overlap connection assembly selected from a group of connectors consisting of nylon rivets, rivets, taps, screws, Velcro®, and staples.
