This piling system is a fast and economical one which has no vibration and limited noise levels associated with it.
Features
· High production levels are attainable in suitable soil conditions
· The system is economical in suitable soil profiles
· Noise levels are low and limited to the engine noise of the piling rigs
· There is no vibration associated with CFA piles
Other Considerations
· The manufacture of the pile is largely in the hands of the operator and there needs to be adequate monitoring of concrete / grout flow and pressure, as well as the extraction rate of the flight, so as to be completely satisfied that the piles are made correctly
· In sandy soils below the water-table there is a reduction in soil strength in the immediate vicinity of the pile due to the drilling operation. As a result of this, the load / deflection performance of a CFA pile is inferior to that of a driven pile
· The steel reinforcing cage is inserted into the wet concrete / grout after the pile is cast
· Soil falling off the flight can contaminate the concrete / grout of the pile shaft
· CFA piles have to be cast to ground level. This results in waste of concrete and excess trimming if there are deep cut-off levels
· There is very limited indication of soil strength during the drilling operation
Pile diameter: 300mm upto 750mm;
