Abstract
A method of mounting and confining poorly and/or unconsolidated core samples for subsequent handling and testing is disclosed. The preferred method comprises the steps of inserting a poorly consolidated core sample into a predetermined length of heat shrinkable tubing. End plugs are inserted at each end of the core sample and within the tubing. Heat is then applied to the heat shrinkable tubing and the tubing shrinks to conform to the outer circumferential surface of the core sample and the end plugs. The tubing is cut off at each end of the poorly consolidated core sample at the line of contact between the poorly consolidated core sample and each end plug. Then the poorly consolidated core sample is seated to attempt to return grains to their in situ grain to grain relationship. Suitable screens are placed against each end of the core sample. Screen caps are then attached to each end of the core sample to provide a constant pressure on the ends of the core sample. The screen caps can then be held in place with shrinkable bands or bonded to each other or tied to each other to form a very durable and useful portable laboratory sample of poorly consolidated earth.
