You have got to modify its knowledge to fit the application. In some cases, there is not any hammer that matches the driving anxiety and resistance boundaries. It might be which the calculated stresses and blow counts are far too significant. One particular alternative is to increase material strength – or make style and design changes. Carry out restrike or static load testing to substantiate ability.

Incorporating pile cushioning is the solution to high stress. Nonetheless, In case your calculations indicate very low stress, there are plenty of possible causes. These involve hammer performance and alignment problems, in addition to weak pile quality.

Execute wave equation Examination of contractor’s gear submission: the Assessment really should be re-performed depending on the pile driving gear the contractor strategies to employ.
