Hi! Screw piles are incredibly simple yet effective in design. They consist of a tubular metal shaft with a screw-shaped tip (blade) – essentially like a giant self-tapping screw. Specialized equipment drives the pile into the ground to the required depth, and pile installation equipment effectively drives the shaft into the soil until it reaches the point of failure (meaning it can’t go deeper and has reached adequate bearing capacity). The most popular method in private construction today is the screw-in method, which uses various operating principles including impact, mixed, pressurized, vibratory, and screw-in techniques. What makes them special is the installation process: a mini-excavator first secures the rod, sets the desired angle, and then gradually screws it into the ground, aided by the tip (blade). Typically, installation occurs at a right angle, though the equipment can drive piles at an inclination of up to 45 degrees for special applications. The screw-shaped blade compacts soil as it penetrates rather than displacing it, creating excellent load-bearing characteristics. Helical pier equipment for sale uses these various operating principles to achieve optimal installation.
