Shelby tube samplers are thin-walled, 空心钢管, which are driven into the ground to extract a relatively undisturbed soil sample f或使用 in laboratory tests used to determine density, 磁导率, compressibility and strength.

Each tube has one end that is chamfered to form a cutting edge and the upper end includes holes for securing the tube to a drive head. Shelby tubes are useful for collecting soils that are particularly sensitive to sampling disturbance, including fine cohesive soils and clays. The tubes can also be used to transport samples back to the lab as well.

注:尺寸为外径. All tubes are 16 gauge steel.

3" and 5" tubes are galvanized
