Apparatus for aerating and draining

1. An aeration and drainage system, comprising:

an aeration & drain pipe having slots on an upper surface thereof;

a frame holding said aeration & drain pipe below the upper surface of said aeration & drain pipe; and

an air and liquid transfer element attached to said aeration & drain pipe and positioned over said slots;

wherein said air and liquid transfer element extends upward from said slots,

wherein said air and liquid transfer element contains openings on a top surface thereof to allow fluids to flow into and out of the air and liquid transfer element, and through the slots in the aeration & drain pipe, and

wherein said frame includes at least one rebar support slot for concrete reinforcing bars.

2. The aeration and drainage system of claim 1 , further comprising:

a removable cap strip positioned on the top surface of the air and liquid transfer element and covering the openings of said air and liquid transfer element.

3. The aeration and drainage system of claim 1 ,

wherein said air and liquid transfer element has a plurality of legs, and

wherein each leg of said air and liquid transfer element has a top flange and a bottom flange, each of the top flange and the bottom flange attaching to said aeration & drain pipe.

4. The aeration and drainage system of claim 1 , further comprising a clamp which is fittable to said frame, such that said frame and said clamp cumulatively surround said aeration & drain pipe, thereby resisting flotation of said aeration & drain pipe during concrete pours.

5. The aeration and drainage system of claim 1 , further comprising:

a primary pipe connected to said aeration & drain pipe, and

an air pump connected to said primary pipe.

6. The aeration and drainage system of claim 1 , further comprising:

a clean-water pipe connected to said aeration & drain pipe; and

a clean water source connected to said water pipe.

7. The aeration and drainage system of claim 1 , further comprising:

a liner, and

wherein said frame rests upon a bottom of said liner.

8. The aeration and drainage system of claim 7 , wherein said frame is engageable with vertical sides of said liner, said liner having a rectangular shape.

9. The aeration and drainage system of claim 1 , wherein said air and liquid transfer element has an inverted U-shape in cross-section, such that an open end of the inverted U-shape opens into said slots.

10. A method of assembling a drainage and aeration system, comprising:

placing a frame on a surface;

placing an aeration & drain pipe on said frame, said aeration & drain pipe having slots located on an upper surface thereof;

placing an air and liquid transfer element into said slots of said aeration & drain pipe; and

placing rebar in at least one rebar support slot located on the frame,

wherein said air and liquid transfer element contains openings to allow fluids to pass through and into said aeration & drain pipe, and

wherein said openings are even or slightly recessed from a surface of a floor to be formed by concrete pouring.

11. The method of claim 10 , further comprising:

placing a lining down on the surface, such that said frame rests upon said lining.

12. The method of claim 11 , further comprising:

pouring concrete inside said liner, in a first pour, and then

pouring concrete in a second pour such that a top surface of the poured concrete is even with or slightly above a top surface of the air and liquid transfer element.

13. The method of claim 10 , wherein said air and liquid transfer element comprises a removable cap strip on a top surface thereof, such that said removable cap strip covers the openings of said air and liquid transfer element.

14. The method of claim 13 , further comprising:

removing the cap strip.

15. The method of claim 10 , further comprising:

flushing the aeration & drain pipe with clean-water using a clean-water pipe which is in communication with said aeration & drain pipe.

16. The method of claim 10 , further comprising:

pumping air to the surface of the floor, through the air and liquid transfer element by providing air from a primary pipe which is connected to the aeration & drain pipe.

17. The method of claim 10 , wherein said air and liquid transfer element has an inverted U-shape in cross-section, such that an open end of the inverted U-shape opens into said slots.

18. An aeration and drainage system, comprising:

an aeration & drain pipe which has slots on an upper surface thereof;

a U-shaped liner;

a frame holding said aeration & drain pipe above a bottom surface of said U-shaped liner; and

an air and liquid transfer element attached to said aeration & drain pipe, positioned over said slots and extending upward from said slots; and

wherein said frame includes at least one rebar support slot for holding rebar,

wherein said frame includes a clamp for holding said aeration & drain pipe,

wherein said air and liquid transfer element contains openings on a top surface thereof to allow fluids to flow into and out of the air and liquid transfer element and through the slots in the aeration & drain pipe, and

wherein a concrete floor is capable of surrounding said aeration and drainage system.

19. The aeration and drainage system according to claim 18 , further comprising:

a removable cap strip located on the top surface of said air and liquid transfer element.
