Push in instrumentation under an angle

One of the advantage of cpt rams are their versatility. We can make cpt's under any angle. Another use you can see on the accompanying photos is pushing in instrumentation under an angle. This makes otherwise awkward jobs relatively easy and mess free. We have carried out projects under buildings, railways, canals. Un unusual use was to survey the depth of the foundation of an old church by probing in a number of angles. In this case a detached set of rams is used using the hydraulics and counterweight of a truck. The detached set of rams can be used in all sorts of environments like cellars, tunnels and any place with limited access or headroom.

CPT inside a Warehouse?

Recently Lankelma undertook a more difficult CPT job inside a warehouse. The job was inside a working warehouse with restricted access and sensitive working conditions. The investigation was to find the underlying soil condition for the possible building of a new housing development.

Originally Boreholes were going to be used to do the entire job. Some were done in the outside loading area of the warehouse.Considering the time they took to do and the noise and mess they caused, it was deemed unsuitable for this method to be carried out inside the working warehouse. Disruption of the day to day running of the warehouse also needed to be kept to a minimum.

CPT’s were then proposed to carrying out the required testing inside the building. Conditions were very tight inside the building but with some skilful driving the truck made it inside. Exhaust fumes had to be extracted using a fan and piping.

Three tests were carried out down to refusal. Final depths were around 20 metres. At each location the concrete floor was cored before the CPT was carried out. The testing took just over 3 hours. CPT’s allowed for all the testing to be carried out in one day and with the minimum of mess. Results were produced for the next working day.
