Abstract

An apertured drainage pipe including a first section being inverted V-shaped and a second section, the second section being substantially flat, the second section having a first turn-up and a second turn-up to receive the first section. The drainage pipe is used with a drainage apparatus for a basement having a outer wall and footer unit and a floor including the outer wall and footer unit having an open area excavation at the inner margin thereof extending from the lower margin of the wall footer unit up to a level above the footer, the outer wall having vertically extending openings therein that are aligned, the drainage apparatus including an excavation in which the drainage pipe is placed and spaced from the footer, the outer wall draining water therefrom into the excavation, the drainage pipe enabling water to flow therethrough from the excavation, and gravel filler to fill in the excavation around the drainage pipe and support the floor.

Claims

1. A drainage pipe, said drainage pipe comprising:

a first section, said first section having first and second legs and an included angle α

therebetween, said first section having apertures;

a second section, said second section being substantially flat, said second section having a first turn-up and a second turn-up, said first section being selectively assembleable to said second section by said first leg being fit against said first turn-up and said second leg being fit against said second turn-up; and

said first and said second legs of said first section of said pipe are capable of being resiliently deformed inwardly.

2. The drainage pipe of claim 1 wherein said apertures have a diameter between 0.25 inches and 2.0 inches.

3. The drainage pipe of claim 2 wherein said apertures have a diameter of 1.0 inch.

4. The drainage pipe of claim 1 wherein said apertures are spaced between 1.0 inches and 12.0 inches apart.

5. The drainage pipe of claim 4 wherein said apertures are spaced 3.0 inches apart.

6. The drainage pipe of claim 1 wherein said first section and said second section of said pipe are capable of being assembled by resiliently deforming inwardly said first and second legs of said first section until a first distance between an edge of said first leg and an edge of said second leg is less than a second distance between an edge of said first turn-up and said second turn-up.

7. The drainage pipe of claim 1 wherein said second section has a width between 4.0 inches and 8.0 inches.

8. The drainage pipe of claim 1 wherein said angle α

is approximately 60 degrees.

9. The drainage pipe of claim 1 wherein a cross-sectional shape of said pipe is an equilateral triangle.

10. A drainage apparatus associated with a basement having an associated outer wall, an associated footer unit, and a floor including said outer wall and footer unit having an open area excavation at an inner margin thereof extending from a lower margin of said wall footer unit up to a level above said footer, said drainage apparatus comprising:

an apertured drainage pipe being spaced from said footer, said outer wall draining water therefrom into said excavation, said drainage pipe enabling water to flow therethrough from said excavation, said drainage pipe being apertured and formed of sections operatively connected together, said drainage pipe having a cross-section of open center triangular shape in vertical section, said sections including an inverted V-shaped upper section and a substantially flat lower section engageable with a lower end of said upper section, said lower section having engaging means for engaging said upper section lower end.

11. The drainage apparatus of claim 10 wherein said excavation is filled with gravel around said drainage pipe.
