Abstract

An aeration and drainage system includes an aeration & drain pipe which contains slots on its upper surface, a stand which holds said aeration & drain pipe above a bottom surface, an air and liquid transfer element attached to the aeration & drain pipe and positioned over said slots. Additionally the air and liquid transfer element extends upward from the slots, and the air and liquid transfer element contains openings on its top to allow fluids to flow into the air and liquid transfer element and through the slots in the aeration & drain pipe.

Claims (17)

1. An aeration system, comprising:

an air pipe having a plurality of holes formed therein;

a plurality of stands which support said air pipe above a surface, said plurality of stands being spaced in the longitudinal direction of said air pipe;

wherein each of said plurality of stands surrounds the circumferential outer surface of said air pipe,

wherein each of said plurality of stands includes a projection which projects in upward, the projection including a hole formed therein, and

wherein said hole in said projection of each of said plurality of stands is positioned such that said hole in said projection coincides with one of said plurality of holes formed in said air pipe, to thereby form an air passage.

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

at least one holder including a projection which projects in an upward direction opposite to the surface and which includes a hole formed therein,

wherein said holder surrounds the circumferential outer surface of said air pipe without supporting said air pipe on the surface.

3. The aeration system of claim 2 , wherein a screw can be removably inserted into said hole in each of said plurality of stands.

4. The aeration system of claim 3 ,

wherein a screw can be removably inserted into said hole in each of said plurality of stands, and

wherein a screw can be removably inserted into said hole in each of said at least one holder.

5. The aeration system of claim 1 , further comprising an air pump connected to said air pipe.

6. The aeration system of claim 2 , further comprising an air pump connected to said air pipe.

7. The aeration system of claim 1 , wherein said plurality of holes are aligned along a longitudinal axis of said air pipe.

8. The aeration system of claim 2 , wherein said plurality of holes are aligned along a longitudinal axis of said air pipe.
