Abstract

A method and apparatus for creating a hole in a soil body. The apparatus includes an open ended tube, a conduit with a nozzle is arranged within the tube. The nozzle has a downwardly facing opening for applying a stream of compressed air downwardly below the bottom open end of the tube to impact the soil. The nozzle also has an upwardly facing opening for simultaneously applying a stream of compressed air upwardly toward the top open end of the tube to facilitate removal of soil particles. This apparatus is utilized to create a hole in which a pile may be installed.

Claims

1. A method of creating a hole in soil comprising the steps of:

providing a tube including a body having an open bottom end and an open top end and a passageway extending between said open bottom and top ends;

arranging the open bottom end of said tube substantially adjacent to a site where it is desired to create a hole; and

applying a stream of compressed air below said open bottom end of said tube, wherein a conduit extending between said open bottom and top ends is used to transport said compressed air through said tube, such that said compressed air stream impacts soil at said site and simultaneously applying said compressed air stream downwardly and upwardly through a nozzle connected to said conduit to facilitate removal of said particles through said open top end of said tube, and moving said tube into said hole along with said conduit and said nozzle until a hole of the desired depth is obtained.

2. The method of claim 1 further comprising the step of removing said conduit from said tube when a hole of a desired depth is obtained.

3. The method of claim 2 further comprising the step of removing said tube from said hole.

4. The method of claim 3 further comprising the step of arranging a substantially solid pile within said hole.

5. The method of claim 2 further comprising the step of placing filler material within the passageway of said tube.

6. The method of claim 5 wherein said filler material comprises concrete.

7. The method of claim 5 wherein said filler material comprises soil.

8. The method of claim 5 wherein said filler material comprises rocks.

9. The method of claim 1 wherein said hole is created solely upon application of the compressed air forcing soil through said passageway of said tube and out of said open top end thereof.

10. The method of claim 1 further comprising the steps of discontinuing the application of the stream of compressed air;

and applying a vacuum source to said conduit such that water encountered during creation of the hole is removed therefrom.

11. An apparatus for creating a hole in soil comprising:

a tube including a body having an open bottom end, an open top end and a passageway extending between said open bottom and open top ends;

a compressed air assembly including a source of compressed air, a conduit and a nozzle connected to said conduit, at least one portion of said conduit being arranged within said tube, said nozzle having a downwardly facing opening for applying a stream of compressed air downwardly below said open bottom end of said tube to impact soil and create a hole at a selected site, said nozzle also having an upwardly facing opening for simultaneously applying a stream of compressed air upwardly through said open top end of said tube to facilitate removal of soil particles, wherein said tube is adapted to be moved into the hole alone with said conduit and said nozzle until the desired depth is obtained.

12. The apparatus of claim 11 wherein said nozzle comprises a plurality of upwardly facing openings.

13. The apparatus of claim 11 wherein said tube comprises an inner wall, said apparatus further comprising a spacing device arranged between said conduit and said inner wall of said tube for maintaining said conduit at a desired position with respect to said inner wall.

14. The apparatus of claim 13 wherein said spacing device is secured to said conduit.

15. The apparatus of claim 14 further comprising an anchor device secured at said open top end of said tube, said conduit being secured to said anchor device.

16. The apparatus of claim 15 wherein said anchor device comprises a hollow cap secured at said open top end of said tube, said anchor device further comprising a cross bar extending through said hollow cap and a clamp in which said conduit is directly secured.

17. The apparatus of claim 11 wherein said nozzle is arranged below said open bottom end of said tube.
