Investigating ground strength by measuring the rate of penetration of a pile

摘要

A method of investigating ground strength for use in piling comprises providing a probe or a driving point 101 at a leading end of a first rod 102 of a pile, pushing the pile into the ground with the probe at the leading end, measuring the rate of penetration and using the rate of penetration to indicate the condition of the ground and thus, predict the rate of penetration and capacity of a given pile. The probe may be used as part of a piling process or as a stand-alone site investigation tool with a length and diameter to match that of a proposed pile.
