Abstract

Claims (45)

1. A plastic drain pipe for drainage comprising:

a first non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at the first joining area, wherein the first non-collapsible section comprises a first plurality of corrugations; and

a second non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at the second joining area, wherein the second non-collapsible section comprises a second plurality of corrugations,

wherein an outermost diameter of the collapsible section of corrugated pipe is approximately the same as an outermost diameter of the first non-collapsible section of corrugated pipe and an outermost diameter of the second non-collapsible section of corrugated pipe.

2. The plastic drain pipe of claim 1 , wherein the pipe sub-section is a first pipe sub-section, and wherein the plastic drain pipe comprises a plurality of pipe sub-sections, each pipe sub-section comprising a collapsible section of corrugated pipe connected to two non-collapsible sections of corrugated pipe.

3. The plastic drain pipe of claim 1 , wherein an end of the first non-collapsible section of corrugated pipe opposite the first joining area is the first end of the plastic drain pipe, and wherein an end of the second non-collapsible section of corrugated pipe opposite the second joining area is the second end of the plastic drain pipe.

4. The plastic drain pipe of claim 1 , wherein the pipe sub-section is foldable into a packaged configuration such that the collapsible section of corrugated pipe forms a bend and the first non-collapsible section of corrugated pipe is positioned adjacent to the second non-collapsible section of corrugated pipe.

5. The plastic drain pipe of claim 1 , wherein a length of the collapsible section of corrugated pipe is less than a length of the first non-collapsible section of corrugated pipe and less than a length of the second non-collapsible section of corrugated pipe.

6. The plastic drain pipe of claim 1 , wherein a length of the collapsible section of corrugated pipe is approximately the same as a length of the first non-collapsible section of corrugated pipe and approximately the same as a length of the second non-collapsible section of corrugated pipe.

7. A method of packaging a plastic drain pipe for drainage comprising:

directing a collapsible section of corrugated pipe of a pipe sub-section between a first end and a second end of the plastic drain pipe to form a bend; and

moving a first non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at a first joining area to be adjacent to a second non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at a second joining area of the collapsible section opposite the first joining area,

wherein the first non-collapsible section comprises a first plurality of corrugations,

wherein the second-non-collapsible section comprises a second plurality of corrugations, and

wherein an outermost diameter of the collapsible section of corrugated pipe is approximately the same as an outermost diameter of the first non-collapsible section and an outermost diameter of the second non-collapsible section.

8. The method of claim 7 , wherein the pipe sub-section is a first pipe sub-section, wherein the plastic drain pipe comprises a plurality of pipe sub-sections, each pipe sub-section comprising a collapsible section of corrugated pipe connected to two non-collapsible sections of corrugated pipe, and wherein the method further comprises directing each collapsible section of corrugated pipe to form a bend and moving the non-collapsible sections of corrugated pipe adjacent to one another.

9. The method of claim 8 , wherein forming the bend in each collapsible section of corrugated pipe and moving the non-collapsible sections of corrugated pipe comprises forming a cuboid.

10. The method of claim 9 , wherein the cuboid is square or rectangular.

11. The method of claim 7 , wherein a length of the collapsible section of corrugated pipe is less than a length of the first non-collapsible section of corrugated pipe and less than a length of the second non-collapsible section of corrugated pipe.

12. The method of claim 7 , wherein a length of the collapsible section of corrugated pipe is approximately the same as a length of the first non-collapsible section of corrugated pipe and approximately the same as a length of the second non-collapsible section of corrugated pipe.

13. A package of plastic drain pipe for drainage comprising:

a drain pipe comprising:

a first end;

a second end; and

a pipe sub-section between the first end and the second end comprising:

a collapsible section of corrugated pipe having a first joining area and a second joining area;

a first non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at the first joining area, wherein the first non-collapsible section comprises a first plurality of corrugations; and

a second non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at the second joining area, wherein the second non-collapsible section comprises a second plurality of corrugations,

wherein an outermost diameter of the collapsible section of corrugated pipe is approximately the same as an outermost diameter of the first non-collapsible section of corrugated pipe and an outermost diameter of the second non-collapsible section of corrugated pipe, and

wherein the collapsible section of corrugated pipe forms a bend and the first non-collapsible section of corrugated pipe is adjacent to the second non-collapsible section of corrugated pipe.

14. The package of claim 13 , wherein the pipe sub-section is a first pipe sub-section, wherein the drain pipe comprises a second pipe sub-section between the first pipe sub-section and the second end, wherein the second pipe sub-section comprises:

a collapsible section of corrugated pipe having a first joining area and a second joining area;

a first non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at the first joining area; and

a second non-collapsible section of corrugated pipe connected to the collapsible section of corrugated pipe at the second joining area,

wherein the collapsible section of corrugated pipe forms a bend and the first non-collapsible section of corrugated pipe is adjacent to the second non-collapsible section of corrugated pipe.

15. The package of claim 14 , wherein the collapsible section of corrugated pipe of the first pipe sub-section and the collapsible section of corrugated pipe of the second pipe sub-section are bent such that the first non-collapsible section of corrugated pipe of the first pipe sub-section, the second non-collapsible section of corrugated pipe of the first pipe sub-section, the first non-collapsible section of corrugated pipe of the second pipe sub-section, and the second non-collapsible section of corrugated pipe of the second pipe sub-section are coplanar.

16. The package of claim 14 , wherein the collapsible section of corrugated pipe of the first pipe sub-section and the collapsible section of corrugated pipe of the second pipe sub-section are bent such that at least two of the first non-collapsible section of corrugated pipe of the first pipe sub-section, the second non-collapsible section of corrugated pipe of the first pipe sub-section, the first non-collapsible section of corrugated pipe of the second pipe sub-section, and the second non-collapsible section of corrugated pipe of the second pipe sub-section are non-coplanar.
