The deepest pile, which was 3.00m in diameter, was bored down to a depth of 118 m. Altogether, 15% of the piles was exceeding 85.00m. To prevent sedimentation at the toe of the piles and to guarantee a clean rock/concrete interface special procedures were implemented during the desanding and air lifting operations of the deepest bored piles.
Large Diameter Piles. Large diameter piles (LDPs) are composite piles deriving their capacity from skin friction from the pile's interaction with the soil as well as end-bearing on the helical plates. The helicals are also a means of pulling down or advancing the pile during the installation process. Advantages and benefits
Large-diameter bored piles and large-hole drillings In-situ concrete piles with diameters of 0.3 m up to 3.0 m are referred to as large-diameter bored piles. For their construction hollow spaces are made in the soil by means of drilling equipment. Depending on …
After concreting, all large diameter bored piles must undergo sonic tests. An emitting probe and a receiving probe are placed inside two separate sonic tubes, and are hoisted up and down the bored pile. The speed at which the sound waves travel indicates the quality of the concrete and the length of the pile.
