Practical Applications of Helical Piles: A State-of-the-Art Literature Review

Abstract

Helical pile is an innovative, fast, cost effective, environment friendly, deep foundation technique, which is used for the construction of both lightly and heavily loaded structures. In this review article use of helical pile have been discussed in different practical projects like construction of new buildings, retrofitting of old buildings and bridges, billboards, electric transmission towers, solar farms, boardwalks, as a bracer in shoring support system. Helical piles have been successfully used in the foundation of onshore wind turbine and now researchers are looking forward to use it in offshore wind turbine which would bring great change in green technology. The prime objective of this article is to increase the level of confidence in people using helical pile as a new foundation technique.
