Resonance Pile Driving with Zero Ground Vibration

The Resonator RD 260 Resonant Pile Driver delivers ground disturbance free, high production pile driving. The Resonator has recently been used on numerous production pile driving sites in the Netherlands and Melbourne, Australia to drive piles in sensitive areas where conventional pile drivers could not be used. Two case histories are provide in this paper which demonstrate the features and benefits of Resonant pile installation.. In the Netherlands the Resonator RD 260 was used at the Vopak Oil Storage facility in the Port of Rotterdam to install pipe and sheet pile within an active pumping gallery. The site demanded vibration free pile installation to construct a cofferdam within sensitive, highly valued assets. Access was an issue and schedule demands were stringent as shutdown windows were narrow. The RD 260 provided ground disturbance free piling immediately adjacent to fragile structures. At Vopak the only site access was using a large crane positioned over 40 m from the location of pile driving. Driving was conducted amongst 900 mm dia pipes carrying heated crude oil. In Melbourne the RD 260 was used to drive GU 18 sheet piling adjacent to light rail easements. The project was the first of many grade separations being constructed within Melbourne urban areas to lower the light rail and provide quieter rapid transit. The original trial used an RGT MR105 series vibrator but noise and vibration criteria were exceeded. The RD 260 was brought in for a trial and performed with high production and produced negligible ground vibration. Up to 17 sheet piles 14 m in length were driven in a 2.5 hour window during the trial.
