In the world of commercial construction, the spotlight often shines on the towering structures that grace our skylines. However, beneath the surface, an equally vital component silently supports these edifices. Helical piles, the uncelebrated heroes of the underground, play a pivotal role in securing the foundations of buildings and bridges. But what exactly is a helical pile, and how do they work? Let’s delve into the fascinating world of these essential deep-foundation champions.
What Are Helical Piles?
At a fundamental level, helical piles are the backbone of structural support, serving as the bedrock upon which various constructions rest. They are known by several monikers, such as screw piles, helical piers, and helical anchors. These invisible giants are designed to disperse the immense weight borne by the structures they underpin. Multiple helical piles are strategically implanted beneath the earth’s surface to form a robust platform upon which buildings, bridges, and other substantial edifices find their footing.
The Composition of Helical Piles
Helical piles primarily consist of round hollow shafts or square solid shafts forged from steel, available in an array of diameters and gauges, tailored to the demands of diverse projects. What distinguishes them as “helical” is the presence of one or more steel screw threads, known as helical bearing plates, securely affixed to the shaft. These plates are pivotal, supplying the necessary downforce to the surrounding soil as the pile is methodically screwed into the earth. While the angle of the screw remains standardized, variations in size and shape are adjusted according to specific applications and soil conditions.
The top of the pile features a shear lug, designed to accommodate machine-driven, rotary hydraulic attachments. These attachments, powered by either compact or large excavators, are chosen in accordance with the pile’s size and the scope of the project. In applications where grouted piles are required, a lead displacement plate is attached to the shaft extensions. This small but significant disc serves to displace soil as the pile is twisted into place, creating a void for the subsequent infusion of concrete.*
The Mechanics Behind Helical Piles
The installation process of helical piles is akin to screwing a corkscrew into a bottle of wine. As the shaft of each pile gradually vanishes beneath the earth’s surface, additional extension segments are affixed through bolted couplers, each further driven into the soil. This seamless amalgamation results in a single, unified pile that can extend hundreds of feet into the ground.
In many instances, the steel pile itself is deemed sufficiently robust to meet the project’s load requirements. However, for more complex deep foundation systems, concrete, also known as grout, becomes an integral part of the equation. In the creation of a grouted column, concrete is continuously poured down the sides of the column, following the displacement plate’s path and enveloping the steel shaft. This method yields a reinforced pillar that is not only capable of withstanding intense compressive forces but also provides steadfast resistance against uplift and lateral pressures.
