Pdf Summary
The Resonator RD 260 uses a hydraulic piston-cylinder system to vibrate piles at frequencies up to 180 Hz. By automatically tuning to a pile’s natural frequency, it excites the pile axially, promoting rapid penetration while limiting vibration transmitted into surrounding ground. The paper reports ground vibration typically below 1–1.5 mm/s near the pile. Two case histories demonstrate its use where conventional piling was unsuitable: - <strong>Vopak oil facility, Rotterdam:</strong> The RD 260 installed sheet piles and open-ended pipe piles beside active oil pipes, valves and galleries, with access provided by a crane positioned more than 35 m away. Measured vibration stayed below the owner’s 5 mm/s limit. Pipe piles up to 28 m long were driven in 20–28 minutes. Some longer sheet piles were slow to advance, apparently because off-axis bending and twisting vibrations caused flange movement, increased clutch friction and diverted energy from penetration. - <strong>Melbourne rail grade separations:</strong> After a conventional vibrator exceeded noise and vibration limits, the RD 260 achieved similar or better production following pre-drilling. It produced about one-thirtieth the ground vibration of the conventional system—up to 1 mm/s at 10 m, compared with readings as high as 30 mm/s—and was 6–10 dBA quieter. Production reached 28–34 sheet piles per day. The authors conclude that resonant driving can install sheet, pipe and other piles rapidly in sensitive settings, with negligible ground disturbance and reduced noise. Performance can be affected by off-axis vibration, particularly in lighter, more flexible sheet piles. Stiffer sections and appropriate clamp placement help reduce this effect.
