Design:
The piles are typically long, cylindrical steel tubes. The length, diameter, and wall thickness of the steel casing are chosen based on the load they're expected to support and the specific ground conditions.
Installation Process: The steel casing is first positioned at the desired location.
Using a heavy weight or hammer (either drop hammer or hydraulic hammer), the casing is then driven into the ground. The impact of the hammer drives the casing tube downward into the soil.
This continues until the pile reaches the desired depth, or when it achieves a specific resistance indicating it's resting in stable ground.
Advantages:
Strength & Durability: Steel is robust and can withstand substantial loads.
Precision: Piles are driven to exact depths, ensuring stability.
Versatility:
Suitable for a variety of soil conditions, especially where there's a need to penetrate through weaker strata to reach more competent soils or bedrock.
Speed:
The driving process is relatively fast, allowing for quicker project turnaround.
Applications:
Steel cased driven piles are commonly used in construction projects like bridges, buildings, and piers, especially in areas with challenging ground conditions where traditional foundations may not be feasible.
In summary, Steel Cased Driven Piling provides a reliable and durable foundation solution, especially in environments where the surface soil isn't strong enough to support heavy structures.
