Application of Screw Piles for traffic sigh poles to reduce carbon footprint in the construction industry

Abstract

Traffic sign poles are very important for controlling and ensuring safe travel on the roads. The foundation work for traffic sign poles mostly uses concrete piles, which are installed by driving piles, causing loud noise. In some projects with space constraints, this can lead to delays. This article presents the use of steel piles in constructing the foundations of traffic sign structures, as steel piles have the advantage of high load-bearing capacity. The installation of steel piles can be done quickly, with no noise and no vibrations. A comparative analysis of the load bearing characteristics of the foundations of steel piles and conventional piles based on field data collection shows that switching to steel pile foundations saves installation time, reduces noise, and has a higher maximum load-bearing capacity than conventional piles. Additionally, steel pile foundations can be easily moved and are 100% recyclable at the end of their lifespan. This also helps reduce the need for concrete, significantly lowering the carbon dioxide emissions of the structure and reducing the amount of earth excavation from the construction site.
