The correct answer is: B. Raking piles
Raking piles are piles that are driven at an angle to the vertical. They are used to increase the capacity of supporting loads on vertical piles. Raking piles are often used in areas with soft soils, as they can provide greater resistance to lateral loads.
A. Construction piles are piles that are driven to support the weight of a structure during construction. They are typically removed once the structure is complete.
C. Eccentric piles are piles that are driven off-center from the vertical. They are used to provide greater resistance to lateral loads.
D. Sinking piles are piles that are driven into the ground until they reach a solid foundation. They are used to support heavy structures in areas with soft soils.
