Combined walls are built out of heavy king piles and lighter sheet piles to protect site jumps up to 30 m of quay walls. Few recommendations exist on how to install the king piles so that the sheet piles can absorb the deformations coming from the location slippage of the king piles. As such the installation process of king piles needs to be regulated. By measuring the installation process on a construction field in Rostock in Germany, the dynamical influence on the king pile's position at the end was investigated. For that purpose, a large king pile with a length of about 30 m was equipped with acceleration, strain and inclination sensors. The driving guide and the installation machine were equipped with acceleration sensors as well. The data was saved with a frame rate of 200 kHz. Next to these analogical sensors the hole driving process is visually recorded by a high-speed camera and a drone. The movement of the king pile during driving derived from the measurement data and compared with the numerical video analyses. The influence of the driving guide was then analysed. Further, the end position of the king pile was measured with an inclinometer.
