        skos:definition  "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. Direct push rigs include both cone penetration testing rigs and direct push sampling rigs such as a PowerProbe or Geoprobe. Direct push rigs typically are limited to drilling in unconsolidated soil materials and very soft rock. Direct push drilling rigs use hydraulic cylinders and a hydraulic hammer in advancing a hollow core sampler, typically no longer than 2 metres, to gather soil and groundwater samples. The core pipe has a valve on top that is used to create a vacuum at the top of the core when pulling the core out of the sediment. The method can be used in up to 5m of water."@en ;
