If the soil cannot bear the weight of a structure, there is a need for a pile foundation. However, the type of condition chosen depends on the type of load, soil condition, site condition, bottom layers, and operational condition. It includes caps and piles where the structure load is transferred to the soil safely using the piles. Pile foundation has many functions, making it applicable in different sectors like construction, oil and gas, offshore wind, etc. This article will discuss situations when pile foundation is necessary and its primary functions.
Situations When Pile Foundation is Used
Specific situations in different industries require pile foundations to meet particular needs. The good thing is that irrespective of your project, professionals are dedicated to helping meet your needs. You can visit the website of IQIP to learn how you can get help with pile foundations. Here are situations when pile foundations are required.
- In a situation when the water table is high, it affects the stability of the foundation. Hence, pile foundations are necessary since they pass through water up to the hard stratum.
- Pile foundations are necessary for areas where the underlying soil is fragile, and the structures are large and heavy.
- Pile foundations are also essential in places with settlement problems due to water table problems and soil liquefaction.
- If the water table rises, it causes an uplift force, especially in offshore platforms and towers. Therefore, a pile foundation is crucial to resist this force.
- There may also be horizontal forces that affect the stability of a structure. Therefore, pile foundations are crucial to resist bending forces while supporting the load. Therefore, a choice like monopiles is necessary to support structures subjected to lateral forces like wind and earthquakes.
- Pile foundations are also utilized in areas prone to soil erosion. They keep structures solid and stable when shallow foundations cannot offer the best support.
- When the structural plan is irregular, it results in irregular load distribution. Therefore, a shallow foundation can cause differential settlement. Pile foundations eliminate this issue by allowing proper distribution of the load.
- Sometimes, a structure may be erected on collapsible, expansive soil that goes deeper into the ground. Expansive soil shrinks and swells with a decrease and increase in moisture. In such a case, a structure may get damaged if erected on shallow foundations. However, a pile foundation is the best alternative to provide the support required to stabilize the structure. The piles are pushed deeper into the stable soil without moisture changes.
The Main Uses of Pile Foundations
Pile foundations play vital roles in different industries
- They help reduce settlement
- Pile foundations provide safety, reliability, and stability for vertical structures
- A pile foundation increases the safety of heavy-load buildings and structures.
- It provides a balanced weight distribution with the fitting pile cap and pile arrangement.
The piles used to build foundations are made from timber, concrete, or steel to provide more structural support than shallow foundations. Even though they are more expensive, they are essential for structural safety.
