HBR 502-2
HBR 502-2: small and lighter but powerful drilling rig for jet grouting
The Hütte HBR 502-2 is a hydraulic drilling rig for jet grouting. Designed with a stroke lenght beetween 3100 mm and 4100 mm, it can create deep foundation elements with a max. Jet Grouting Depht of 9,5 m / 10,5 m. The HBR 502-2 is one of the most compact and efficient rig for jet grouting and it has been manufactured also with increased power. Designed to be lighter and highly efficient, it is suited for difficult drilling conditions in confined and limited areas, which require particularly compact and mobile equipment.
Jet Grouting is applied when civil engineering works require soil improvement to build new structures or to restore the existing foundations. These techniques are employed in a wide range of cases such as underpinning of existing structures, diaphragm walls, structural and waterproof bottom plugs, tunnel consolidation, launch and arrival shafts for TBM and slope consolidations as well.
The HBR 502-2 has been engineered for jet grouting but it is also intended for many other drilling applications as it can be tailored to any costumer need or geological conditions.
