Bored Piles installation

Large bored piles are used as foundation elements to carry concentrated building
loads into deeper, more stable soil layers. Bored piles can be easily adapted to the various
load and soil requirements due to the large variety in diameter and construction
techniques. Single pile diameter can vary between 30 and 300 cm. It can be constructed
in all kinds of soil conditions.
In contrast to driven piles, bored piles enable the immediate In-situ evaluation of drilled soil
layers to revise foundation length due to changed soil conditions. Construction methods of bored
piles can be categorized as;

(i) The bored holed stabilization process of fully cased, partial cased, uncased and fluid stabilized excavation.

(ii) The casing installation method– either by driving the casing with a free fall hammer or weight, vibrating the casing, pneumatic installation or hydraulic installation with the help of a rotary drive, an oscillator or rotator.

(iii) The excavation method – either by grab excavation, rotary drilling, airlifting, and flush boring. Combinations of air-lifting and reversed circulation drilling can drillbore holes up to 150m depth efficiently, depending on soil conditions.

Understanding Foundation and Choosing the best foundation for your building construction.

Foundations provide support to the structure, transfers the loads from the structure to the soil. But the layer at which the foundation transfers the load shall have an adequate bearing capacity and suitable settlement characteristics. There are several types of foundation depending on various considerations such as-

Total load from the superstructure.
Soil conditions.
Water level.
Noise and vibrations sensitivity.
Available resources.
Time-frame of the project.
Cost.
Broadly speaking, foundations can be classified as shallow foundations and deep foundations. Shallow footings are usually used when the bearing capacity of the surface soil is adequate to carry the loads imposed by a structure. On the other hand, deep foundations are usually used when the bearing capacity of the surface soil is not sufficient to carry the loads imposed by a structure. So, the loads have to be transferred to a deeper level where the soil layer has a higher bearing capacity.

Difference between Shallow and Deep Foundation.

The depth of shallow foundation is generally about 3 meters or the depth of foundation is less than the footing with.
Deep foundations are generally more expensive than shallow foundation. The construction process of a deep foundation is more complex. Shallow foundations transfer loads mostly by end bearing.

What is Pile Foundation.

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.

Pile foundations are deep foundations. They are formed by long, slender, columnar elements typically made from steel or reinforced concrete, or sometimes timber. A foundation is described as 'piled' when its depth is more than three times its breadth.

Atkinson, 2007
Pile foundations are usually used for large structures and in situations where the soil at shallow depth is not suitable to resist excessive settlement, resist uplift, etc.

When to Use Pile Foundation.

Following are the situations when using a pile foundation system can be;

When the groundwater table is high.

Heavy and un-uniform loads from superstructure are imposed.

Other types of foundations are costlier or not feasible.
When the soil at shallow depth is compressible.

When there is the possibility of scouring, due to its location near the river bed or seashore, etc.

When there is a canal or deep drainage systems near the structure.

When soil excavation is not possible up to the desired depth due to poor soil condition.

When it becomes impossible to keep the foundation trenches dry by pumping or by any other measure due to heavy inflow of seepage.

If your property is swamoy/waterlogged area, please make sure you do a soil test before erecting your structures to ascertain the suitable foundation to be used.

Don't waste that millions, a sinking building/structure has no economical at the long run.

We continue from here next time.
