Massenza MI4
Equipment list
Pesi operates a Massenza MI4, a compact fully hydraulic multi-drill rig with full set of tool string to execute geotechnical site investigation drilling, insitu testing and sampling. It is fitted with an automatic trip hammer for standard penetration test (SPT) and other in-situ tests and drilling.
The rig is capable of the following drilling methodology:
- Wireline rotary drilling – consolidated sediment and rock coring
Conventional rotary drilling – consolidated sediment and rock coring - Percussive drilling with windowless sampling
- Down The Hole (DTH) drilling in rock fill
- Auger drilling
- Wash Flush with a drag bit
- Wireline rotary drilling – consolidated sediment and rock coring
The automatic trip hammer is a standard mass of 63.5kg used for standard penetration test (SPT) and dynamic probe super heavy (DPSH) test as well as percussive drilling using the windowless sampler
- Undisturbed sampling in cohesive soil using a thin-walled Shelby sampler having a 76.3mm OD, a wall thickness of 1.63mm and an area ratio of 9% to capture high quality undisturbed sample. The sampler which can be 500mm or 750mm long is pushed continuously (not hammered) with the drilling rig hydraulic clamps to achieve minimal disturbance of the sample when sampled.
- Soil sampling with windowless sampler fitted with a plastic liner for quality sample capturing
- Rock core sample using a triple tube barrel
