P60 Slope Climbing Rig

At Geotechnical Engineering Limited we are constantly trying to improve. We believe in finding better, more economical ways to carry out ground investigations through innovation. We have a wide range of plant to carry out drilling operations in a variety of locations and we really can go where others can't or won't!

Traditionally, boreholes on slopes involved a delicate balance between cost and achievable depth, the two options being either hand held, windowless sampling or lifting at least one rig on to a scaffold platform. We knew that the hand held gave little or no valuable information and that the scaffold option was time-consuming, expensive, labour intensive and carried risks. In the firm belief that "there's always a better way", resources powered us to design and develop a "slope climbing rig", thus the P45 was born.

The P45 was a resounding success but that left us wanting more.

To this end, the P60 was created.  Modelled on our extensive fleet of Pioneer rigs, the award winning P60 slope climbing rigs are dual purpose and can dynamically sample soils, as well as coring and open holing through rock. The result is one rig to carry out both techniques.

The P60 is supported onsite by a mule platform which works alongside the rig providing a safe and stable platform for the drilling operatives and engineers.

The rig and its mule are mobilised to site safely and securely on a tachographed flat-bed vehicle owned and managed by Geotechnical Engineering Ltd.  The ancillary kit and materials are transported within the support vehicle and the operation is supported by an experienced and trained three man crew.

Soft soils are investigated using dynamic sampling up to 20m deep to obtain continuous samples retained in a semi-rigid plastic liner providing a continuous soil profile for ground modelling and sampling.  Discrete strata can be identified for contamination sampling purposes.  Rotary core drilling can be carried out up to 50m deep to obtain continuous rock cores, again retained in a semi-rigid plastic liner.

In-situ testing in the form of calibrated SPTs in general accordance with BS EN ISO 22476-3 can be carried out.  Undisturbed UT100, U100 and U70 samples can be taken in cohesive soils.

Borehole instrumentation can be installed including 19mm and 50mm standpipes and pneumatic, hydraulic or vibrating wire piezometers for groundwater or gas monitoring and inclinometer tubing to monitor slope movement.
