Method for attachment of parts to thin walled tubes for sampling and coring of soils and other substrates

摘要

#$%^&*AU2015101432A420151119.pdf#####6 ABSTARCT Sampling of soils and other materials with thin walled tubes provides many benefits in minimizing forces needed for tube insertion. Attachment of fittings to thin walled tubes such as cutting tips can be problematic but necessary. A method for joining thin walled sampling parts to each other is presented involving the machining of a mating annular groove in both parts and using a wire inserted into the groove as a key to lock them together.fluter- Part Innee Pnr D i I N N ,N. .
