THE GEOTECHNICAL “PIONEER” ROTARY RIG

The multi-purpose Pioneer drilling rig was developed to be a versatile, compact yet powerful machine to carry out a wide variety of ground investigations in many different situations. We currently operate 16 Pioneer rigs, in 3 different versions with integral mono pumps. The rigs are transported to site on flat-bed trucks, accompanied by support vans carrying ancillary equipment and materials.

__________

Pioneer rig dimensions & weights:

  • Operating: 1.6m/4.6m/4m Working area: 7m by 2.5m minimum
  • Weight: 3.5 tonnes

__________

The Pioneer High Torque (Technodrill) is capable of:

  • Dynamic sampling (see above)
  • Hollow stem flight auger boring to 20m, forming boreholes of up to 300mm diameter
  • Allowing installation of up to 150mm diameter Standpipes

__________

The Pioneer Rig is capable of:

The rig is capable of working in restricted areas and forming boreholes (and sampling) at any angle. Dynamic sampling of soils to 20m deep to obtain near undisturbed continuous samples up to 112mm diameter retained in a plastic liner, forming boreholes of up to 143mm diameter. Hollow stem flight auger boring to 20m, forming boreholes of up to 250mm diameter and allowing installation of up to 125mm diameter standpipes.
Standard penetration testing (SPT) BS EN ISO 22476-3. Undisturbed soil sampling of 100mm and 70mm diameter. Rotary core drilling to 80m deep to obtain continuous rock cores of up to 112mm diameter, using a range of drilling flushes.

__________

Both versions are capable of:

  • Concrete coring
  • Forming boreholes for a variety of ground remediation techniques
  • Installing standpipes, monitoring wells, biaxial inclinometer tubing, and installation of various other instruments
