THE GEOTECHNICAL “PIONEER 3” ROTARY RIG
The multi-purpose Pioneer3 drilling rig was developed to be a versatile, compact and powerful machine to carry out a wide variety of ground investigations in many different situations. The rigs are equipped to drill with wireline methods including Geobor S. As with our other Pioneer rigs they have their own transport and their support vehicle carries all ancillary equipment and materials.
Dimensions/Equipment: Access width/height/length: 1.74m/2.61m/4.82m Operating: 1.74m/4.86m/4.53m Working area: 7m by 2.5m minimum Weight: 4.60 tonnes Applications:
• Dynamic sampling of soils to obtain near-undisturbed continuous samples retained in liner.
• Rotary core or rotary open hole to in excess of 100m with a range of methods and flushing media.
• Drill holes up to 300mm diameter where required.
Sampling and Insitu Testing: • Continuous dynamic sampling up to 112mm
diameter, retained and sealed in liner. • Continuous wireline or conventional coring in
a maximum of Geobore S size to provide 102mm cores all retained and sealed in liner.
• Standard penetration testing (SPT) BS EN ISO 22476-3.
• Soft ground Geobor S coring to provide Eurocode Class 1 samples subject to ground type.
• Undisturbed soil sampling of U100mm, UT100mm and 70mm diameter
Instrumentation: All standard and many bespoke methods of installation can be accommodated including standpipes for gas and groundwater monitoring, biaxial inclinometer tubing and all types of vibrating wire piezometer.
