Bored piles - Designing Buildings Wiki - Share your construction industry knowledge. Bored piles, also known as replacement piles, are a commonly-used form of building foundation that provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics.
TECHNOLOGY Bored Piles
The large diameter bored piles are foundation structure characterized by a cylindrical shape with a diameter larger than 600 mm; manufactured by excavating ground through a rotary drilling equipment with a complete soil removal and cast in place by casting concrete into the borehole. The bored piles construction entails two main
SPECIAL CONSIDERATIONS IN MARINE PILE DESIGN AND …
Steel piles are very popular in Europe and America. Availability of heavy capacity driving hammer in one hand and non-availability of large number of workforce on the other hand made this pile more popular than bored piles in those countries. Racker steel piles can also be constructed. Quality control is more easily achievable in steel piles.
PILE LOAD CAPACITY – CALCULATION METHODS
piles which tend to displace a large amount of soil due to the driving process are called full-displacement piles. Cast-in-place (or bored) piles do not cause any soil displacement, therefore, they are non-displace-ment piles. Piles may be loaded axially and/or transversely. The limit states necessary to be considered in the
