Helical Pile Technology Indigenized in Iran for Stronger Foundations
“Helical pile is a well-known technology in the world and countries like the US and Germany have specific guidelines and regulations for this type of foundation and they have been working on this technology for years,” said Behnam Bidar, the managing director of the company.
He explained that this type of foundation is in the form of a screw and made of steel with a galvanized coating, adding that it has various uses in construction of different buildings like villas and greenhouses, and in manufacturing energy production equipment like solar panels and power transmission towers.
“In this company, we succeeded in production of this foundation which is a type of screw foundation made of metal.
It consists of a tubular shaft with one or more spiral metal plates that transmits the tensile or compressive force of the structure to the ground through the shaft and spiral plates.”
A helical pile is a deep foundation solution suitable for supporting light and heavy structures. They are engineered to support compressive loads less than 1kN (225 lb) or in excess of 5,000kN (1.125 million lb) – from a small landing to a 32 story tower, helical piles are an option. Another common name for helical piles are “screw piles”.
A helical pile consists of a round steel shaft and one or more helical bearing blades which are welded to the shaft. The length, thickness and diameter of a shaft varies based on several factors as will the number, thickness and diameter of helical piles. Regardless of dimensions, the helical should be formed with a consistent pitch (plane or angle) to ensure reliable design and installation methods which are consistent with generally accepted engineering guidelines.
