Performance of Pile Driving Systems: Inspection Manual

摘要

A study was undertaken on the performance of pile driving systems and the existing technology for the measurement of performance parameters was reviewed. The report is an inspection manual for use by pile driving inspectors and engineers to ascertain that the pile hammer conforms to certain minimum standards, and to record observations on hammer and driving system behavior. The manual considers only impact hammers; i.e., a large weight is alternately being raised and then accelerated downward, impacting against the pile top. Vibratory hammers, which operate on a different principle altogether, have been excluded from the manual. In addition to pile impact hammers, the manual addresses the complete driving system to include cushions, helmets, and leads. Also included as an aid to the inspector/engineer, are comprehensive field inspection data forms.
