Pile with Grout Vortex

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.

What is claimed is: 
     
         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.
