Solid Engineering: Application of the Pile Foundation System

Modern construction projects require foundation systems that are suitable for the ground characteristics and are durable. Particularly for large buildings, bridges, viaducts, and projects constructed in areas close to water, establishing a solid infrastructure is of critical importance. The pile foundation system, used in such projects to enhance safety and ensure longevity, provides a strong foundation even on low-bearing-capacity soils. In this article, we will discuss what the pile foundation system is, where and how it is applied, and under what conditions it yields the most efficient results.

What is the Pile Foundation System?

The pile foundation system is a foundation solution that carries and distributes the loads of a structure through piles placed beneath the ground. This method is commonly used to ensure the safety of structures on soft or weak soils and is widely preferred in various engineering projects. Piles are placed into deep soil layers through special machinery, ensuring the structure remains stable. This system increases the stability of the structure by distributing the load deep into the ground, rather than to the surface.

Piles are typically made of concrete or steel and are highly durable. These piles penetrate into the strong layers of the ground to create a solid foundation for the structure. Even if the ground characteristics are weak, the pile method increases the soil’s bearing capacity and provides a secure foundation. For this reason, this system is widely used in high-rise buildings, large construction projects, port structures, bridges, and viaducts.

Where is the Pile Foundation System Applied?

The pile foundation system has a wide range of applications and can be used in various types of soil. It is typically preferred in the following types of structures:

• High-Rise Buildings: Skyscrapers, office buildings, hospitals, and other multi-story structures require strong foundation systems due to their high weight. In such buildings, the pile foundation system ensures that the structure is securely seated on the ground.
• Bridges and Viaducts: Bridges and viaducts, which require high load-bearing capacity, use pile foundations to create a strong foundation that can safely support the structure.
• Ports and Marine Structures: In areas near sea level or underwater projects, the soil can be very soft or weak. The pile foundation system is preferred to provide a solid infrastructure in such soils.
• Earthquake-Prone Areas: Structures built in earthquake zones require resilient foundation systems for safety. The pile foundation system ensures that the soil is resistant to seismic vibrations during an earthquake.

The application of this system is not limited to weak soils; it can also be used to enhance safety in strong soils. Especially in earthquake-prone areas, the pile foundation system offers a significant advantage by making the structure more resilient to tremors.

How is the Pile Foundation System Applied?

The application process of the pile foundation system requires careful planning and the use of advanced equipment. The steps involved are as follows:

1. Soil Analysis: Before starting the project, a soil survey is conducted, and the soil’s bearing capacity, structural properties, and depth are analyzed. These analyses provide information on how deep the piles will be placed and which materials will be used.
2. Pile Drilling Process: After the soil analysis, special machines are used to dig holes in the ground for placing the piles. The depth and width of these holes are determined based on the structural load and the soil properties.
3. Pile Placement: Steel or concrete piles are placed into the drilled holes. These piles are selected from durable materials that can carry the weight of the structure and are prepared according to the soil characteristics.
4. Concrete Pouring and Stabilization: After the piles are placed, the holes are filled with concrete. This process ensures that the piles bond with the ground and form a solid foundation. Once the concrete curing period is complete, the piles become more durable.
5. Testing Process: After the piles are placed, their load-bearing capacities are tested. The structure’s ability to bear weight and its safety are tested, ensuring a solid foundation is created.

For the successful implementation of the pile foundation system, a professional team and advanced machinery are required. A pile foundation application made according to the soil conditions increases the structure’s lifespan and guarantees its safety.

In Which Systems Does the Pile Foundation Work Well?

The pile foundation system works more effectively in certain soil types and types of structures. The conditions where this system yields the best results are as follows:

• Soft Soils: In areas with soft and loose soil structure, piles are driven deep into the ground, enhancing the stability of the soil.
• High Groundwater Levels: In areas where the water table is high, the ground may not have a durable structure. Piles provide resistance against water and improve the safety of the structure.
• Structures Requiring Deep Foundations: For high-rise buildings or projects where heavy loads need to be supported, the pile foundation system is one of the most suitable solutions. In such projects, solid foundations increase the structure’s durability.
• Earthquake-Prone Areas: In areas with earthquake risk, the pile foundation system ensures that the structure is more resistant to seismic activity. This system supports the structure against horizontal and vertical forces generated during an earthquake.

What Are the Advantages of the Pile Foundation System?

The pile foundation system offers various advantages for construction projects and ensures the safety of structures in areas with weak soil conditions. The advantages are as follows:

• Creates a Solid Foundation: The pile foundation system increases the bearing capacity of the soil and ensures the structure is built on a secure foundation.
• Earthquake Resistance: It makes the structure more resilient against earthquake risks. By absorbing ground movements during an earthquake, it reduces the damage to the structure.
• Environmentally Friendly Solution: The pile foundation system is applied according to the soil properties, causing no harm to the environment and requiring less excavation compared to other foundation types.
• Long-Lasting: Piles made from durable materials like steel or concrete ensure the structure remains securely standing for many years.
• Easy to Apply: Especially for large projects, the system can be applied quickly with machinery, speeding up the construction process.

The pile foundation system offers an ideal solution when a safe and durable foundation needs to be created in construction projects. Particularly preferred in areas with weak soil conditions, this system ensures the longevity of structures and compliance with high safety standards. With the development of construction technologies, the application of the pile foundation system has become easier, and safety measures in large projects have been increased.
