Abstract: A portable vibracoring system provides an efficient, rapid, and safe means of extracting cores up to 33 feet (10 meters) long. Short cores (less than 10 feet or 3 meters long) are also obtained with a part of the system. This report describes the system and the coring procedures for intrusion, extraction, and packaging. The coring system is composed of the following modifications of existing designs: (a) a quick fasten release clamp that attaches the vibrator head to the coring pipe (the clamp moves up and down the coring pipe like a "sleeve," eliminating having to completely remove the unit) and (b) a stable tripod with four separate, portable components. During extraction, the core is stabilized in a vertical position by a spring-loaded metal gate, using a core pipe slot cut into the tripod headplate, until extraction is completed.
