How much does each rotation screw the pile into the ground?

Hello everyone! How much does each rotation screw the pile into the ground? Trying to calculate how many turns we'll need.

Hello! Each complete rotation screws the helical pile 192mm (approximately 7.5 inches) into the ground. So you can calculate the approximate number of turns needed by dividing your required pile depth by 192mm. For example, if you need piles at 2.5 meters depth, that would require about 13 full rotations. However, keep in mind that soil conditions greatly affect this - harder soil or obstacles can slow progress significantly, while very soft soil might allow faster penetration. The consistency isn't always uniform throughout the depth either. It's crucial that throughout all these rotations, one person continuously monitors the vertical alignment with a spirit level, as any deviation accumulates with each turn. The two people turning the pile need to maintain steady, consistent force to prevent jerking or sudden shifts. More information about the complete process is available at https://about-the-foundation.blogspot.c ... piles.html Remember that trained workers take 5-15 minutes per pile, while beginners need much longer - this time includes carefully monitoring alignment throughout all rotations and making adjustments as needed.
