3.5 TONNE CPT TRACK MOUNTED RIG (CPT003)

We have a variety of rigs giving us the capacity to meet our clients’ needs and specifications for each individual project.

This rubber tracked mini rig weighs 3.5 tonnes and is able to push up to a depth of 10-30 metres, depending on the groundconditions. Its hydraulically driven screw anchors enable it to have a 20 tonne ram thrust capacity. It can be attached tomarine jack-ups and rail trailers or craned into areas of restricted access making this rig ideal for confined locations.

PROJECT REVIEW

ALBERT DOCKS, LIVERPOOLIn Situ Site Investigation completed a specialist water project withinthe Albert Docks in Liverpool. Our Mini Rig, CPT 003, was craned ontoa spud leg multi cap vessel and transported across the dock tocomplete tests over the water. Proposed redevelopment of the arearequired significant geological testing and by utilising our mini riganchored onto a vessel, our client was saved the cost and time ofdraining the dock in order to assess the ground conditions.

A total of 3 MOSTAPs, 7 shear vanes and 14 CPTs were completedwithin the 5 day window given. We successfully used our newelectronic shear vane testing equipment to measure the in situstrength of the ground. The CPTs went to a target depth ofapproximately 3 metres through the soft sediment before stoppingat the bedrock.

CANTERBURYThe redevelopment of an old bank in Canterbury required the use ofour Mini Rig for the investigation carried out in its basement. This sitewas particularly restricted and required careful management andprecision to get the rig into position. The rig was trackedapproximately 200m in order to enter the building. Once inside, therig was craned into a pre-made hole and lowered down into thedepths of the basement. An exhaust extractor was connected toremove fumes inside the confined space and testing commenced.

For this project, we utilised our combined cone, which allows us tocomplete a UXO survey and carry out CPTs at the same time. 10 CPTswere completed to a depth of 8-10 meters and went into underlyingclay over sand.
