DRIVEN TUBE PILES

This system is not used extensively mainly due to the high cost of the steel tubes.  There are, however, situations where the positive features of the system outweigh the costs.  Small pile sizes are commonly used for underpinning houses and light buildings with limited headroom and poor access.  Medium pile sizes are commonly used for piling new column foundations within existing buildings or in difficult access areas.  The larger pile sizes are used mostly for river bridge foundations and in marine construction.


Positive Features

  • There is an extensive range of pile sizes
  • The system can achieve considerable depths (> 60 metres in a suitable profile)
  • The pile is permanently cased and thus ideal for river and marine work
  • It can be installed in limited headroom
  • It can be installed in areas with very difficult access
  • The shaft is cast in the dry so quality control is good
  • Noise levels are not high

Other Considerations

  • It is a relatively expensive system
  • There is vibration associated with the driving of the tube
