Piling: Definition, Uses, and Installation Process

Piles are cylindrical or block-shaped structures used in building construction to support the load of the building above them. Piles are usually made of materials such as reinforced concrete, steel, wood, or a combination of these materials. They are planted vertically into the ground to create a solid and stable foundation for the building above it. The following will discuss further the definition, use, and process of installing piles.

Definition of Piles
Piles are vital elements in building construction that aim to transfer structural loads from buildings to more stable soil layers below. They are usually planted deep enough into the ground to reach layers that have adequate bearing capacity. The selection of pile types and their planting depth depends on the characteristics of the soil and the load to be supported.

Uses of Piles
Supporting Building Loads: The main function of piles is to channel building loads into the ground effectively, preventing subsidence or shifting that can damage the building structure.

Structural Stabilization: By penetrating more stable soil layers, piles help increase the overall stability of the building structure, especially on soft or unstable soil.

Protecting Buildings from Damage: Unstable or cracked soil can cause damage to buildings over time. By supporting the load efficiently, piles can reduce the risk of damage caused by changes in the soil.

Pile Installation Process
The process of installing piles involves several important steps:

Soil Investigation: Before the installation of piles begins, a soil investigation is carried out to determine the characteristics of the soil at the site. This is important for selecting the appropriate type of pile and its depth.

Drilling Holes: Holes are required for installing piles. The holes must be of the recommended diameter and depth as per the structural design.

Pile Installation: The piles are inserted into the prepared holes using special equipment such as cranes or pile driving machines. They are then positioned vertically and fixed properly.

Hole Filling: Once the piles are properly placed, the surrounding holes are filled with additional material such as sand or cast concrete to increase their stability and bearing capacity.

Depth Check: The depth of the piles must be checked carefully to ensure that they reach adequate soil layers to safely support the building load.

Load Testing: On some projects, piles may be load tested to ensure that they can safely withstand the anticipated loads.

With proper installation, piles can provide a strong and reliable foundation for a variety of buildings, from homes to large structures such as bridges and skyscrapers.
