Technical Details

Bored piling is a method that involves boring a circular hole into the ground, installing steel reinforcement and filling the bore hole with concrete to form a pile. Boring is carried out to the required depth by means of either a crawler crane-mounted rotary boring unit or a purpose-built hydraulic drilling machine. Bored pile foundations are suitable for all types of soil conditions and compared with conventional driven piling methods, bored piling activities generate less noise and vibration. Static load tests are used to verify the capacity of bored piles. The most common reaction frame is the kentledge system. Also used are reaction piles, to provide tensile resistance. Conventional static load tests provide valuable data regarding the actual capacity of the installed piles, the corresponding design assumptions, and the distribution of load along the length of the pile
