A Direct Push Rig

August 5th, 2008

Direct push technology includes several types of drilling rigs and drilling equipment which advances a drill string by pushing or hammering without rotating the drill string. This should perhaps not properly be called drilling, however the same basic results are achieved. Direct push rigs include both cone penetration testing rigs and direct push sampling rigs such as a Geoprobe. Direct push rigs typically are limited to drilling in unconsolidated soil materials, very soft rock. Geoprobe rigs, used at offshore oil rig jobs, use hydraulic cylinders and a hydraulic hammer in advancing a hollow core sampler to gather soil and groundwater samples. The speed and depth of penetration is largely dependent on the soil type.
