i <br /> EGG GREGG IN SITU, INC. <br /> i <br /> Geotechnical and Environmental In Situ Testing Contractors <br /> THE PI EZO CONE PENETROMETER <br /> The electrical piezocone (CPTU) is the <br /> premier soil logging tool. The CPTU provides <br /> a rapid, reliable and economic means of <br /> determining soil stratigraphy, relative density, <br /> strength and equilibrium groundwater <br /> . pressures. <br /> Gregg In Situ offers a choice of 2.5, 5, 10 and <br /> ` 15 ton tip (Qc) capacity cones. Our cones <br /> E also have variable capacity friction sleeves <br /> (Fs) and pore pressure (U). The pore <br /> f Triaxial Geophones pressure can be measured at one of 2 <br /> or Accelerometer locations, either on the face of the cone tip or <br /> (VP&Vg) behind the cone tip. Pore pressure <br /> dissipation data is recorded automatically. <br /> All data is displayed in real time at the ground <br /> Inclinometer(1) surface, facilitating the on site decision <br /> making process. Feld data reduction, plotting <br /> Thermistor(T) and CPT interpretation can be carried out <br /> upon request. <br /> Friction Sleeve(Fs) <br /> Load Cells <br /> Pore Pressure <br /> Porous Filter Transducer(U) <br /> Element <br /> Cone Tip(Qr) <br /> EGGGeotechnical and Environmental In Situ Testing Contractors <br /> Los Angeles • San Francisco • Houston • Aiken <br /> Vancouver • Edmonton • Salt Lake City • New Jersey <br /> 7ef:(923)313-5800• Fan.(925)313-0302 • &maih gmo@ecfs.com <br /> I <br /> 1 <br />
