Innovative Dutch piling technique could benefit UK

Dieseko Group’s vibrationless Resonator could benefit the UK’s piling industry, says chair of Steel Piling Group.

Presenting at the Steel Piling Group earlier this month, Dieseko Group introduced a method of driving steel piles into the ground without vibration.

Called the Resonator, the steel pile can be installed and extracted steel piles at their natural frequency. As a result it drives itself into the ground like a spring.

The high frequency vibrator resonates the pile, essentially changing the pile into an axial spring to excite the toe of the pile with high accelerations and low amplitude. This produces high penetration rates but the high frequency stress waves are dissipated in the soil.

Yet to be used in the UK, Steel Piling Group chair Chris Barker believes it would be benefit projects where vibrations are an issue.

Barker said: “Resonant pile driving is an ingenious way to install steel piles without vibration. I can see many applications for this technology in the UK where adjacent structures and infrastructure like railways are sensitive to vibrations.”

The method has been successfully tested in the Netherlands on 34m long micro piles, deeper anchors in harder soils, to install both combi sheet piles or dyke stabilisation and for displacement bearing piles.

Barker added: “If any engineers still think of steel piling being driven into the ground with old diesel hammers, they should come along to our meetings and see how the steel piling industry are innovating to meet the challenges of construction in the 21st century.”

Other innovations in steel piling construction techniques presented at the Steel Piling Group meeting included VolkerStevin’s autonomous hydraulic piling gate used at Dover Western Docks Revival project and Quinn Piling/McLaughlin and Harvey’s RD interlocking tubular steel pile wall installation in granite at Peterhead Harbour.
