Helical piles are a seamless tubular shaft whose profile allows it to be screwed into the ground by rotating it with simultaneous axial load. When the length of the shaft is insufficient to penetrate a dense soil layer, composite supports are used for installation. The shaft can be made up of several rods that are assembled using a coupling connection as the support is driven in. The shaft can be single-section or composite. This installation feature of pile foundation is advantageous as it enables the designer to make corrections to their calculations.

A steel pile equipped with a coupling connection is a composite structure comprised of three distinct components, namely the pile, extension, and coupling.

Steel helical pile with a coupling connection

A coupled pile is a welded steel pipe with an attached helix. The hollow shaft is cut at a 45-degree angle at the bottom, with technological holes located at the top.

The extension piece is a steel pipe with a diameter similar to that of the pile, and it features technological holes along its body.

The coupling is a larger diameter pipe with technological holes that serves as a connecting element between the pile and the extension piece. The components are connected together through a bolted connection.
