Standard square shaft helical piles are usually mounted using compact equipment like a skid-steer loader or excavator with an hydraulic drive head. This approach not only speeds up the process of installation but also lessens the requirement to prepare the ground thoroughly. The operator plays a crucial role in ensuring the piles are placed in a straight line, using both visual cues as well as assistance from ground crews.
One of the main factors in helical pile construction is achieving the required load capacity. This is where the correlation between the installation tension and capacity is vital. Contemporary torque indicator, such as those from Chance Digital Torque Indicator, are a key component in this process, providing accurate measurements, and removing the uncertainty that are associated with the estimation of hydraulic pressure.
The operating speed during installation is crucial, usually ranging between 8 to 16 RPM. This controlled speed makes sure that the pile advances approximately 3 inches per revolution, consistent to the helical plate's pitch. If the pile does not move according to plan, adjustments such as raising downward thrust or adding larger helical plates are made to avoid 'spinning out' similar to the threads of a screw being stripped.

Helical piles are also excellent in sustainability, a key concern in modern construction practices. Since they cause minimal disturbance to the area and don't need concrete to construct, their impact on the environment is considerably less than foundations constructed with traditional materials. Furthermore, they are typically made from recycled steel, and their ability to be removed allows them to be reused, improving their eco-friendly appearance.
Another benefit of helical piles is their capacity for load-bearing immediately after installation. This immediate load transfer capability lets construction proceed without a delay, which is in stark contrast to the delays for concrete foundations. It also gives you an advantage in emergencies or when dealing with unstable structures that need immediate stability.
The landscape of modern construction is always changing as new technology and methods continuously evolving to tackle the challenges of the 21st century. In the midst of these developments, helical piles have gained much attention because they provide a robust and versatile foundation that can meet the many requirements of modern construction projects.
Alongside their main benefits, helical piles have a variety of other advantageous features that further strengthen their place in modern construction. They include:
These additional advantages, when combined with their primary benefits, are what make the helical piles a highly versatile and efficient foundation option for a wide range in construction tasks.
In the constantly evolving world of construction, helical piles have emerged as a hidden gem, providing strengths that are changing the industry. This article focuses on the distinct advantages of the installation of helical piles, and explains why they are increasingly favored in the modern day construction projects.
Helical piles, also referred to as screw piles are foundation option that is distinguished by their spiral-shaped plates attached to a central steel shaft. This unique design makes it easy and quick installation since the piles are essentially installed into the ground. This technique is in sharp contrast to traditional foundation techniques, offering distinct advantages.
In addition to the strengths of the helical piles and their use in construction projects brings many advantages. These are in the following manner:
These issues highlight the multiple advantages of using the helical piles in highlighting their role in improving efficiency, sustainability, and cost-effectiveness in construction.
