What is Piling Construction

Introduction

It is often seen that the building foundations are weak to bear a superstructure load without any support. These supports can be the soil reinforcement techniques, the techniques for reducing the intensity of the acting on the foundations of a building, and the methods for transmitting the structure loads to deeper strata.

But out of all these supports, Piling is the most efficient option yet a bit more expensive than its other alternatives. Piling construction is considered so efficient because it uses columns-like structures to transfer the load of the building loads to deep strata below.

Perhaps you might be new to the world of construction. If so, it is always recommended to have a valuable and reliable reference guide to understand what the construction term and technique means for which you seek information. So, here is a guide to piling construction that will help you familiarise yourself with the bare essentials of Piling.

What is piling construction?

Piling is considered an effective construction technique that provides the essential support needed for structures of any kind. This technique is used in the construction of bridges, buildings, and other projects when the soil present at the project site is incapable of supporting the necessary weight for the structure at shallow depth. So, in such cases, Pile in construction proves to be very helpful in setting deep foundations for the construction work. Thus, it is essential to pick the right equipment and workforce to embark on piling construction at the required site.

While in operation, Piling is taken into the ground till it hits bedrock. This is the point where the pile can safely support the structure’s weight above the ground. However, for driving the pile efficiently,  several attachments are welded to the pile’s end as per the design and project architecture needs.

Materials used for pile in construction

The piling process includes the use of different kinds of materials. People choose wood, concrete, or steel as their piling materials in many cases. Since the structural base under the ground is meant to support large structures, the ultimate goal is to keep any building sturdy. This is why the choice of piling materials is very crucial.

How is pile foundation in construction done?

Piling works by inserting huge amounts of steel, wood, or concrete into the ground soil. This deep insertion of the elements facilitates a sturdier base for the project construction. It includes a lot of measuring, planning, and hard labour. Thus, the technique of Piling needs to be monitored and executed by highly-skilled engineers and the workforce. This is crucial to ensure that the foundation is secure and the Piling has been performed in the right way so that the building base would be as solid as a rock.

However, the piling process can’t be started without considering important factors such as soil condition beneath the ground. This consideration helps in determining the type of material that suits best to be inserted during Piling.

Use of pile driver and its benefits

The process of Piling is not like the structural steel, where the format of a complex project is constructed typically by tilting a beam or tube up. Pile driver is used to driving Piling into the ground. This could be understood by the example when you take a hammer to nail any object into a wall. Similarly, in most cases, the pile driver uses a hydraulic hammer for placing the pile into the ground. The force varies depending on the type of soil to drive it accurately into the ground.

There are several other benefits of using a pile driver and steel piling at both the site of construction and for the environment, such as:

  • Piling has become the top choice for most deep foundation projects due to its less invasive and minimal disruption techniques.
  • Steel piles have become a trusted installation method at the project site due to their fast installation.
  • From an environmental point of view, steel is one of the most recyclable materials globally. It can be turned from piles into thousands of other essential items throughout its life cycle.

Problems faced during piling

●      Deterioration of steel or concrete

         The steel and concrete parts of the pile can face damage during the construction process.

●      The collapse of sides of piles

         There could be a collapse in the sides of the piles if the casing is not closed correctly,

●      Settlement of the adjacent area

         Driving the piles creates excellent vibrations that could raise the pore water pressure in surrounding soils and decrease their stability.

●      Excessive water in pile holes

         Pile holes could face the excessive flow of the groundwater while driving the piles in the ground.

Conclusion

In short, pile engineering is the method of providing the soil with the needed strength to carry the load of the structure, and it is beneficial for transforming the weak and incapable soil.
