Inventory double-wall Casing 800 mm is used for the installation of bored piles for deep foundation and serves to protect the walls of the well in unstable soils. Keeping the geometry of the borehole walls from crumbling and preventing the ingress of groundwater into the internal space, casing pipes provide the maximum quality of filling the borehole with concrete. They are used when working with all brands of drilling rigs such as Bauer, Liebherr, Delmag, Casagrande, Soilmec, Junttan, XCMG, SANY, ZOOMLION, CZM, etc. Work with Casing pipes is carried out both directly from the rotary of the drilling rig through a Casing Driver Adaptor, and using a Casing Oscillator. Sections of the Casing pipe are connected into a drill string of a common length to reach the design drilling depth.
