The installation of bottom driven piles is quick and efficient.
A thin walled steel tube, closed ended, is driven in lengths of 1.5~6m using an internal drop hammer on to a dry concrete plug. The tubes are jointed by a full fillet weld as the installation proceeds
The depth of the piles are designed using a predetermined set or length criteria
Once the required depth is reched the tube is filled with high slump concrete or grout. A single bar or cage is then inserted
These piles are suitable in most ground conditions. Costly spoil removal is not required, a particular advantage on brownfield sites
Advantages
Small lightweight equipment, need small space and height
low noise and vibration
no spoil to be removed
minimal site preparation
Automatically control drop down and up
