Reducing diving forces for pressed in piles

Driving sheet piles into stiff clay using jacking methods can often only be achieved after pre auguring or water jetting to reduce driving forces. Both these activities contribute significantly to potentially damaging ground movements. Whilst driving shoes have been used in the past they have not been associated with reduced driving forces. However, the paper describes a series of tests that have successfully explored the influence of driving shoes as a means of reducing friction. This will encourage the use of installing sheet piles without the need to resort to the damaging practices that are currently in use.
