Rig Intrumentation and CFA (Augercast) automation
LOADTEST provides expert independent service in the field of piling rig instrumentation. Specifically, with the supply, fitting and servicing of piling rig instrumentation and the full automation of continuous flight auger piling process.
Continuous Flight Auger (CFA) or auger cast piling has two specific phases of operation. Firstly, the digging phase where the auger rotates and penetrates the ground to the desired depth. Secondly, the construction phase where the auger is withdrawn whilst concrete or grout is pumped through the hollow auger to replace the removed spoil. Both aspect of the automated CFA process are patented.
Reliable construction of this type of pile is essential, both for design considerations and from a commercial viewpoint.
Commercially, correct and automated construction of the piles on a given site can make substantial savings over piles constructed manually and without due consideration of the piling process. By drilling the pile efficiently and by controlling the supply of concrete to the auger during construction, both the design and commercial aspects of the piling process are met. Precision monitoring of instrumentation is essential and data storage and retrieval allows for checking of the whole construction process.
From the data recorded, complete pile installation records can be printed and the data obtained during the piling process can be used for further analysis and storage in a database system. This information can then be made available as a management tool for the analysis of individual rig performance, operator performance, contract performance and allowing review of the overall company performance. As a consequence, the entire CFA operation can be reviewed in detail by statistical analyses, allowing management to make changes to piling practices and ensuring maximum efficiency from each rig.
