What is the typical rule for determining the depth to set straight line poles in soil?

The typical rule for determining the depth to set straight line poles in soil is based on a formula that ensures the stability and security of the poles. Setting the poles too shallow can compromise their effectiveness in supporting the structures they are intended to uphold. The correct formula, which is 10% of the pole length plus an additional 2 feet, takes into account the pole's length while also providing a sufficient depth to resist the forces of wind and other environmental factors.

This method is widely used as it balances the need for anchorage with practicality, avoiding excessive digging or the use of unnecessary materials. The standard also allows for adjustment based on the specific conditions of the soil and the height of the pole, ensuring they remain upright and effective over time. By following this guideline, one can effectively provide adequate support while minimizing the risk of pole failure.
