| Rock Core Samples |
Rock coring is used to obtain in-situ rock / soil samples and strength parameters through tests such as the Standard Penetration Test (SPT). "Cylinder samples from 4 to 8 inches in diameter and 6 to 12 inches long... may also be obtained by jacking or otherwise pushing drive samples into exposed surfaces using a continuous steady pressure. Hydraulic power equipment may also be used to push Shelby tubes into exposed undisturbed soil to collect undisturbed samples, such as the sampler mounted on a backhoe."[1]
