What is Pile Foundation?
A pile foundation, a type of deep foundation, is a thin column or long cylinder composed of concrete or steel used to support the structure and transfer the load at the necessary depth by end bearing or skin friction.
Pile foundations are typically utilized for large structures and when the shallow depth soil is insufficient to resist excessive settlement, uplift, and other issues.
Uses of Pile Foundation:
In the following circumstances, piling foundations are preferred.
- The superstructure’s load is heavy, and it’s distributed unevenly.
- Water pumping from open trenches for shallow foundations is challenging and expensive.
- The bearing capacity of the topsoil is low.
- The water level in the subsoil is high, so
- The water level in the subsoil varies dramatically.
- Timbering the trenches is tough and expensive.
- The character of the topsoil is expansive.
- The structure is located along the water’s edge or in a riverbed, vulnerable to scouring.
- Near the foundation, canal or deep drainage lines escape.
- The foundation of transmission towers, an off-shore platform vulnerable to uplift forces, is made of piles.
