A Tool for Removing Neutron Probe Access Tubes from the Soil1
- Ralph E. Campbell
The tool which is described consists of a tapered shaft jacketed in a split sleeve with matching taper. As the shaft is pulled, it slips in the sleeve causing the sleeve to expand against the inner wall of the access tube. Friction between the sleeve and the tube wall holds the puller in place as the tube is drawn from the soil.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
