Bored piles

Bored piles. Bored piles are large-diameter (1 to 2 m) concrete foundation elements that are cast in-situ and can be installed up to great depths. Very suitable for transferring large concentrated loads (20 MN is feasible) into the soil. These piles are produced using a heavy-duty rig with a rotary drill that rotates a telescopic kelly bar with ...

Concreting of Pile Foundations

For the design purpose of bore cast-in-situ piles, the strength of concrete mix using above mentioned quantities of cement is taken as M20. Concreting for the piles is to be done with tremie of suitable diameter. Natural rounded shingle of appropriate size may be used as coarse aggregate. It helps to give high slump with less water cement ratio.
