What is a Helical Pile?
Helical piles are a manufactured steel foundation anchor. This anchor is then driven into the ground at the specified depth. This is done using hydraulic machinery, which comes in various sizes dependent on the jobs needs. Helical piers are used for a variety of applications such as residential foundation repair, decks and patios, oil and gas, industrial, amusement parks, government projects, wind and solar energy, and new and existing commercial foundation projects. The helical pile is suited for almost any foundation project out there.
How to Install a Helical Pile:
The helical piles must be installed according to a preapproved plan of placement.
1. Installation begins by attaching the helical pile lead section to the torque motor (drive head) using a drive tool and drive pin.
2. Next, crowd must be applied to force the pilot point into the ground at the proper location, inclination and orientation, as described in the placement plan.
3. Then the pile must be rotated into the ground in a smooth, clockwise, continuous manner while maintaining sufficient crowd to promote normal advancement (approximately 3 inches per revolution).
4. Installation continues by adding extension sections, as necessary.
Refer to the approved construction documents for type, grade, size and number of bolts and nuts that are required to connect the shaft sections.
5. Inclination and alignment shall be checked and adjusted periodically during installation.
