Bottom Driving Casing Technique Predictions with TNOWAVE
The driving of a casing pile with the impact of the hammer at the toe or bottom of the pile is an effective method compared to driving with the hammer at the pile top. A significant reduction of driving time and noise has been observed for this type of driving. All energy of the impact hammer is transferred to the driving point at the pile bottom. Depending on the state of the configuration, part of the energy will be used to pull the casing downward. The driving of the casing is done by tension forces, instead of compression forces as is the case with normal impact driving at the pile top. So, the energy of the impact hammer is delivered to the point of the pile where it has the highest effect. The bottom driving casing technique has been developed by IHC Hydrohammer and Bouygues Offshore. This method is presently called Pile Toe Driving System (PTDS). The TNOWAVE stress wave program has been extended with the model for the bottom driving casing technique. The applied model for the simulation is discussed and a practical application is shown and acceptable results have been obtained.
