16-02-2009
First 700mm Pile Installed in the UK with ZU-100 Kowan Still Worker
Contractor J.T. Mackley working for the Environment Agency used a Kowan ZU-100 supplied by Watson & Hillhouse to drive a 48 metre run of AZ28-700, 13 metre long piles.
This is the first time that AZ 700 mm piles have been installed with a pile press in the UK.
The piles were installed 8 metres into: 3 metres of soft clay, 2 metres of medium dense gravel and 3 metres of dense gravel.
The piling was in front of an existing pile wall which was failing with a pile upstand of approximately 5 metres.
Once the piling was completed a walk back device was used to walk the Still Worker back to within reach of the crane.
The Still Worker is able to install 580mm to 708 mm ‘Z’ piles and 600mm to 750mm ‘U’ piles.
The Ram at the back of the ZU-100 assists the unit in self-travelling.
