J N Piling Ltd are currently undertaking works on behalf of Blue3, who are working for UK Power Networks on behalf of Network Rail.
Piles are being installed using a Movax vibratory hammer on a 360º tracked excavator. The excavator will use an excavator mounted rotary auger drive and set of appropriate length auger flights to pre-auger prior to pile installation. Pile distribution will be by the 360o tracked excavator.
The Giken SCZ675WM will install permanent sheet piles in the form of AZ 26-700 pairs 9.0m – 9.5m long, forming a permanent retaining wall.
The Giken SCZ675WM Silent Piler will install the piles in Supercrush mode (with pre-augering equipment) without water jetting equipment.
