Square shafts with helical piles are usually constructed using small equipment such as a skid-steer loader, or an excavator, equipped with an hydraulic drive head. This approach not only speeds up the process of installation but also eliminates the need to prepare the ground thoroughly. Operators play a vital role in ensuring that the piles are properly placed by using visual signals and the assistance of ground personnel.
One of the main aspects of helical pile installation is to achieve the required load capacity. This is the point where the connection between the installation torque and load capacity is crucial. Modern torque indicators, such as those from Chance Digital Torque Indicator, play a pivotal role in this process, providing accurate measurements and eliminating the uncertainty in the estimation of hydraulic pressure.
The speed at which the installation takes place is critical, typically ranging between 8 to 16 RPM. This controlled speed will ensure that the pile advances approximately 3 inches per revolution, consistent to the helical plate's pitch. If the pile isn't moving according to plan, adjustments such as the increase of downward thrust or the addition of larger plates to avoid 'spinning out' similar to a screw ripping its threads.

The variety that helical piles offer is yet another reason for their increasing popularity.
Helical piles boast remarkable versatility that allows them to adapt to a wide range of soil types and environmental conditions. This adaptability is vital in areas with problematic soils or high water tables or limited access, which pose challenges to conventional foundation methods. Helical piles can be customized to fulfill specific soil load and load requirements, making them suitable for anything from small residences to massive commercial structures and infrastructure projects.
Sustainability is a major consideration in modern construction and helical piles perform well in this respect. They cause minimal soil disturbance, reducing the environmental impact compared to traditional methods. Furthermore, they are often made from recycled steel and can be completely removed and reused which improves their eco-friendly quality. This is becoming increasingly crucial as the industry moves towards greener building practices.
Another benefit of helical piles is their immediate capacity to bear loads.
In addition to their primary advantages, helical piles are also equipped with other advantages that strengthen their place in modern construction. They include:
These additional advantages, when combined with their primary advantages are what create the helical piles extremely flexible and reliable foundation choice for a wide range types of projects.
Speed of construction is among the main advantages of helical piles. Unlike conventional foundations that require long excavation and curing they can be put in place quickly, often within hours. This is not just saving time, but also lowers labor costs which makes the projects more affordable.
A further advantage of helical piles lies in their comparatively low environmental impact. Their process of installation is less intrusive, causing less soil disturbance. This feature is particularly beneficial in ecologically sensitive areas or in urban settings where preserving the integrity of the environment is essential.
Building on the foundational strengths of helical piles, their use in construction projects brings many advantages. These can be outlined as follows:
These points highlight the multifaceted benefits of making use of helical piles, emphasizing their role in improving sustainability, efficiency, and cost-effectiveness in construction.
