The first <br /> Geoprobe was built for the Environmental <br /> ' Protection Agency in 1988. <br /> a <br /> Soil probing techniques can be thought of as a i•, <br /> subcategory of what are commonly referred to as It - <br /> `Direct Push"techniques_ Direct push refers to <br /> ' tools and sensors that are inserted into the ground it s' �� " I ■ , ' _ - <br /> without the use of drilling to remove sail and make <br /> a path for the tool. A Geoprobe relies on a = �I { <br /> ' relatively small amount of static(vehicle)weight i f <br /> combined with percussion as the energy for <br /> advancement of a tool string. <br /> t Using a Geoprobe,you can drive tools to obtain <br /> continuous soil cores or discrete soil samples.

You can insert permanent <br /> ' sampling implants and air sparging points. You <br /> can drive a conductivity sensor probe to map <br /> subsurface <br /> Ilthology. in fact, How does a Geoprobe work? <br /> ' the Geoprobe has k ' ram Soli probing equipment is typically used for site <br /> been used to investigations to depths of 30 to 64 feet(9 to 10 m). <br /> perform all of However,this range is elusive and constantly <br /> these functions to `' increasing as better probing equipment is produced. <br /> ' depths of 100 feet Geoprobe soil probing equipment has been used to <br /> 130 ml or more. depths exceeding 100 feet(30 m)in many areas of <br /> the United states. <br /> You will find <br /> Geoprobe • It's hydraulically powered either from a vehicle <br /> equipment on four or an auxiliary engine_ <br /> continents and <br /> places in between. it utilizes static force and the dynamic percussion <br /> ' You will find it force of the awosomo GH-40 Sol]Probing <br /> used In UST Rammer to advance small diameter sampling <br /> investigations, tools. <br /> property audits, <br /> ' Superfund sites, • It rearranges particles in the subsurface by <br /> remediation application of weight and percussion to advance <br /> projects,and a tool string and produces no cuttings in the <br /> research, Its uses ;• process. <br /> are as diverse as <br /> ' its users. • It can drilf through surface pavements t2 inches <br /> (305 mm)or more in thlckness and probes <br /> beneath them. <br /> ' The Geoprobe Is a hydraulically-powered soil It can be used for collecting soil cores, <br /> probing machine which uses static force and a groundwater samples,and soil gas samples.
