Concrete Cased Piles are a type of pile foundation where the pile is encased in concrete to provide additional strength and stability. The following piles are examples of concrete cased piles:
Raymond Pile: This is a type of concrete cased pile where a steel casing is driven into the ground, and then concrete is pumped inside to form the pile. The Raymond pile is commonly used for deep foundations in soft soils. Thus, this is a concrete cased pile.
Swage Pile: The Swage pile also involves a steel casing that is driven into the ground, and concrete is poured inside the casing. This method is also a type of concrete cased pile, as it uses the casing to provide extra support and prevent soil displacement during pile installation.
Vibro Pile: Vibro piles are typically installed by using vibration to densify the surrounding soil or drive the pile into the ground. Vibro piles do not involve a concrete casing, so this is not a concrete cased pile.
Simplex Pile: Simplex piles are not concrete cased piles. They generally do not use a casing but rely on other methods like grout or concrete for stability. Therefore, this is not a concrete cased pile.
Conclusion: The correct options are (A) Raymond Pile and (B) Swage Pile as they are examples of concrete cased piles.
