Deeppiles

Deep piles are a type of foundation system used in civil engineering to transfer structural loads to deeper, more competent soil or rock strata. They are typically installed when the surface soils are weak, compressible, or unstable, and cannot adequately support the intended structure. The installation process involves drilling or driving a long, slender element, known as a pile, into the ground until it reaches a suitable bearing layer.

There are several types of deep piles, including driven piles and bored piles. Driven piles are usually pre-fabricated elements, such as concrete or steel, that are hammered or vibrated into the ground. Bored piles, also known as drilled shafts, are created by drilling a hole into the ground and then filling it with concrete, often reinforced with steel. The choice between driven and bored piles depends on factors such as soil conditions, load requirements, and site accessibility.

Deep piles function in two primary ways: end bearing and skin friction. End bearing piles transfer the load to a strong stratum at the pile's tip. Skin friction piles rely on the frictional resistance between the pile's shaft and the surrounding soil to support the load. Many deep piles utilize a combination of both. They are essential for constructing tall buildings, bridges, offshore platforms, and other structures in challenging ground conditions.
