You need to modify its details to fit the application. Occasionally, there's no hammer that matches the driving pressure and resistance boundaries. It might be which the calculated stresses and blow counts are too higher. Just one option is to boost content energy – or make style and design modifications. Execute restrike or static load testing to verify capacity.

Introducing pile cushioning is the answer to large worry. Nevertheless, When your calculations indicate lower pressure, there are many opportunity brings about. These involve hammer overall performance and alignment troubles, as well as lousy pile quality.
