Bore piles are cast-in-situ piles. They can be made in various diameters, larger than Ø45 cm, and in different lengths. Bore piles are constructed by drilling a circular hole into the ground and placing reinforcement and concrete into this hole. Bore piles are applied as foundation piles, retaining piles, and intersecting pile types. Bore piles are commonly used for deep foundations in the construction of structures with deep soil layers that have reliable bearing capacity or structures expected to experience differential settlements due to their static systems. Bore piles are also used in deep excavation support systems and slope stability solutions as part of the retaining system. They are applied in foundation systems and retaining systems. A bore pile machine is used to drill according to the project’s requirements. Once the drilling is complete, reinforcement and concrete (using a tremie pipe) are placed in the shaft to complete the construction. In non-cohesive soils, a steel casing pipe is inserted into the ground during the drilling process. The casing pipe is withdrawn from the ground after the concrete placement is completed.
