Inclinometer Casing
Inclinometer Casing
(OP)
Hi All,
I am having trouble with some erroneous readings from two boreholes that are fitted with inclinometers. The Inclinometer probe skips out of the tracks when I reel it up to the top of the casing.
I expect that the problem relates to poor installation. My inital thought is that the casing that the contractor has used is not adequate/ the grooves are not deep enough.
I know that the readings I am getting are incorrect because other older inclinometers that are installed at the site are not showing excessive movement.
Can anyone recommend tried and tested inclinometer tubing that will hold the probe within its tracks?
Thanks in advance

RE: Inclinometer Casing
The boreholes were sunk to 20mbgl. The probe is a Biaxial Inclinometer System, supplied by Soil Instruments.
Yes one of our engineers was present while the boreholes were drilled. 70mm diameter GAGE Technique inclinometer casing was used.
It is very difficult to identify a potential cause. The reason I expect the casing may be at fault is because the same contractor has let us down at another site by installing faulty inclinometers. Which may point towards the type of casing being the problem.
Thanks
