Device for Cutting Sediment Core Liners.

摘要

Longitudinally cutting the core-barrel liner containing a coastal sediment core. Most coring devices use plastic or thin-wall metal tubing as core-barrel liners. Coastal sediments entering the core barrel during the drilling operations are contained within this liner which is removed, capped, identified, and stored. In order to make a detailed visual log of the core and to selectively sample the sediments it is necessary to split the core lengthwise into halves. An assembly for splitting core liners that has proven very satisfactory at the Coastal Engineering Research Center is described below.
