The standard square shaft piles are typically mounted using compact equipment such as a skid-steer loader, or excavator with hydraulic drive heads. This method not only speeds up the process of installation but also eliminates the need for extensive ground preparation. The operator plays an essential part in making sure that the piles are installed plumb, using both visual signals and the assistance of ground workers.
One of the most important elements of helical pile installation is to achieve the desired load capacity. This is when the relationship between installation tension and capacity is vital. The most modern torque gauges, like the Chance Digital Torque Indicator, are crucial to this process, providing accurate measurements and eliminating the uncertainty in hydraulic pressure estimations.
The operating speed during installation is vital, generally ranges between 8 and 16 RPM. This controlled speed will ensure that the pile is moving about 3 inches per revolution, which is in line with the pitch of the helical plates. If the pile doesn't advance in the manner expected, adjustments such as increasing downward thrust or adding larger helical plates are made to prevent spinning out, akin to a screw ripping its threads.

One of the main advantages of helical piles is their rapid installation. Unlike traditional foundations, which often require extensive excavation and curing in concrete. Helical piles can be screwed directly into the ground. This method is not only more efficient but is also less disruptive to the surrounding environment. It also reduces total construction time, which allows projects to be completed faster. The speed of installation is particularly beneficial in times in which minimizing disruption is essential like in urban areas or near fragile ecological areas.
In addition to their primary benefits, helical piles have a variety of other advantageous features that further solidify their position in modern construction. They include:
These additional attributes, along with their primary advantages, create helical piles a highly versatile and reliable foundation choice for a wide range of construction projects.
In the constantly evolving construction industry Helical piles have risen as a hidden treasure, with strengths that are changing the construction industry.
Helical piles, also referred to as screw piles, are a foundation option that is distinguished by their spiral-shaped plates that are attached to a steel shaft. This design is innovative and makes it easy and quick installation because the piles are essentially placed into the ground. This technique is in stark contrast to conventional foundation methods, and offers significant advantages.
In addition to the strengths of the helical piles, their use in construction projects brings many advantages. These are as follows:
These factors highlight the many advantages of the use of helical piles, emphasizing their role in enhancing efficiency, sustainability and efficiency in construction.
