Dormer Construction have recently acquired and commissioned a Giken Silent Piler. It is believed to be the only unit of its type currently in New Zealand.
This hydraulic machine is capable of performing vibration-free installation and extraction of sheet piles. It operates by gripping previously driven piles to provide reaction force for pressing in the next pile.
The Silent Piler works on top of the reaction piles and self-travels to the next position as illustrated below. This technique allows sheet pile driving at sites not accessible for conventional piling techniques. Only a relatively light-weight service crane is needed to pitch the sheet piles.
Dormer Construction’s Silent Piler fills an important niche in the sheet piling field. This coupled with our 25 tonne, mobile crane and RX2000 tracked piler means we are able to cover all eventualities, offering a full service in all sheet piling situations.
Our rig has already proven itself invaluable at the Canterbury District Health Board (CDHB) and at St George’s Hospital, where day to day activities have carried on, unaffected by our piling operations.

Self-moving Procedure
Reaction Piles
The silent piler unit allows for the installation and extraction of sheet piles in tight areas and where noise and vibration are unwelcome. For example: residential areas, hospitals, schools and where ground has been badly damaged and vibration could lead to further localised complications.
The silent piler unit comprises a powerful hydraulic press / sheet pile installation unit, which is coupled to remote, fully silenced, hydraulic power pack and generator units. The combined facility allows installation of sheet piles without the need to employ a vibrating power head, keeping noise to an absolute minimum and most importantly, vibration to zero.

Self-moving Procedure
Reaction Piles
5. Press-in pile number 5 until the pile is sufficiently stable
6. release Clamps from the reaction piles and raise the main body
7. Move Saddle forward to the next position on the reaction piles
8. lower the main body onto reaction piles number 2-4 and clamp them to complete pressing-in pile number 5
