Abstract
The present invention relates to a piling, comprising a pile that includes a pipe provided with a generally cylindrical shape, a first end, and a second end, a first end fitting located at the first end of the pipe, a second end fitting located at the second end of the pipe, the first end fitting is provided with an out-of-round shape that transmits torque and is dimensioned so that at least a portion fits within the second end fitting, and the second end fitting is provided with an out-of-round shape that transmits torque with at least a portion that fits about a portion of the first end fitting.
Claims20
A piling, comprising:
- a) a pile that includes:
- i) a pipe provided with a generally cylindrical shape, a first end, and a second end;
- ii) a first end fitting welded to the first end of the pipe;
- iii) a second end fitting welded to the second end of the pipe;
