- A pile is defined as a slender column of transferring the structural load the deep underlying Layers.
- Foundations provide support to the structure, transfers the loads from the structure to the soil.
- The piles, therefore, have end tip or point contact, just sufficient to rest on the deep-seated rock. At the grounds, the pile is covered with the pile cap on which columns can be constructed.
- Accounting to the action of the pile is to support the load, the pile’s cap on which columns can be constructed. accounting for the action of the pile to support the load.
- Pile foundation, a kind of deep foundation, is actually a slender column or long cylinder made of materials such as concrete or steel which are used to support the structure and transfer the load at desired depth either by end bearing or skin friction.
when using pile foundation system can be :
- When groundwater table is high.
- When the soil at a shallow depth is compressible.
- When there is a canal or deep drainage systems near the structure.
The piles are classified as :
The place where hard strata are available at a very great depth, the piles are designed to transfer the load by the phenomenon of skin friction along the length of the piles. Such piles are called friction piles. Friction piles are useful in cohesive soils with low bearing capacity.
End bearing piles
End bearing piles transfer l load through the soft soil to suitable bearing stratum. Multi-strayed buildings are invariably founded on end bearing piles. End bearing piles. End bearing piles are useful when hard strata are available within reasonable depth in loose soil having the low bearing capacity.
