Abstract

A pile is provided for installation into earth, comprising, a shaft that includes a shaft axis, a plurality of helices, and a metal that is capable of being welded so as to securely attach the helices; the shaft is provided with an end that has been configured for successive piling; the helices are shaped so that, when the shaft is torqued, the helices screw the pile into the earth about the shaft axis; a bladed portion provide with a shaft-accommodating section, a pile securing structure, a collar, and a blade; the shaft-accommodating section of the bladed portion is shaped according to the end of the shaft; the pile securing structure is configured to cooperate with a fastener; the collar of the bladed portion is generally concentric about the shaft axis; and the blade is shaped, at least in part, to agitate grout.

Claims

1. :

A pile for installation into earth, comprising,

a) a shaft that includes a shaft axis, a plurality of helices, and a metal that is capable of being welded so as to securely attach the helices;

b) the shaft is provided with an end that has been configured for successive piling;

c) the helices are shaped so that, when the shaft is torqued, the helices screw the pile into the earth about the shaft axis;

d) a bladed portion provided with a shaft-accommodating section, a pile securing structure, a collar, and a blade;

e) the shaft-accommodating section of the bladed portion is shaped according to the end of the shaft;

f) the pile securing structure is configured to cooperate with a fastener;

g) the collar of the bladed portion is generally concentric about the shaft axis; and

h) the blade is shaped, at least in part, to agitate grout.

2. :

A pile according to claim 1 wherein the blade extends axially from the shaft-accommodating section of the bladed portion.

3. :

A pile according to claim 1 wherein the collar is shaped to create a generally cylindrical volume about the shaft axis.

4. :

A pile according to claim 1 wherein the bladed portion has been cast through use of a sand mold.

5. :

A pile according to claim 1 wherein the bladed portion is fabricated through use of lost-form casting methods.

6. A pile according to claim 1 wherein the blade is a generally flat plane that extends radially from the shaft-accommodating section.

7. :

A pile according to claim 1 wherein the bladed portion is further provided with an angled blade.

8. :

A pile according to claim 7 wherein the angled blade is arranged about the shaft axis so that the blades extend, at least in part, radially.

9. :

A pile according to claim 1 wherein the blade is shaped to create a vortex when rotated within a column of grout.

10. :

A pile for installation into earth, comprising,

a) a pipe that includes an axis, a plurality of helices, and a metal that is capable of being welded so as to securely attach an end fitting;

b) the end fitting has been configured for successive piling;

c) the helices are shaped so that, when the shaft is torqued, the helices screw the pile into the earth about the shaft axis;

d) a bladed portion provided with a shaft-accommodating section, a pile securing structure, a collar, and a blade;

e) the shaft-accommodating section of the bladed portion is shaped according to the end of the shaft;

f) the pile securing structure is configured to cooperate with a fastener;

g) the collar of the bladed portion is generally concentric about the shaft axis; and

h) the blade is shaped, at least in part, to agitate grout.

11. :

A pile according to claim 10 wherein the blade extends axially from the shaft-accommodating section of the bladed portion.

12. :

A pile according to claim 10 wherein the collar is shaped to create a generally cylindrical volume about the shaft axis.

13. :

A pile according to claim 10 wherein the bladed portion has been cast through use of a sand mold.

14. :

A pile according to claim 10 wherein the bladed portion is fabricated through use of lost-form casting methods.

15. :

A pile according to claim 10 wherein the blade is a generally flat plane that extends radially from the shaft-accommodating section.

16. :

A pile according to claim 10 wherein the bladed portion is further provided with an angled blade.

17. :

A pile according to claim 16 wherein the angled blade is arranged about the shaft axis so that the blades extend, at least in part, radially.

18. :

A pile according to claim 10 wherein the blade is shaped to create a vortex when rotated within a column of grout.
