What it is
The principle of a piled embankment is to create a platform on top of soft compressible soils that is supported by elements and does not load the soft compressible soils to be able to construct an embankment in a short period of time with very limited settlements. In our AuGeo piled embankment system the element with which the load is transferred to the bearing strata is The AuGeo pile is a pile installed by static push force without vibrations and often used with a casing protecting the concrete to aggressive acids. Because all loads are transferred, the soft compressible soil into which the piles are installed remain unloaded.
How it works
The load of an embankment is transferred to the piles by the natural arching in the high frictional mattress construction towards the stiff elements installed in the compressible material. The section underneath the arching is supported and transferred towards the piles by the high strength geogrid placed on top of the piles. This created a full transfer of the embankment load and a guarantee that no material is lost from the mattress.
Why it's used
Piled embankments are most of the time used to limit the residual settlement after construction and are applied next to bridges or hard shoulders where there is no settlement. This improves the transition zone. The system is also used when the construction period does not allow for the regularly used consolidation solutions. The AuGeo system is, due to the use of the static push force well suited for projects in locations where existing infrastructure and buildings or infrastructure is present that must not be subjected to vibration and settlement damage. Thanks to the high production rates that can be attained, large areas can be made settlement-free in short periods.
