The CPTU provides <br /> a rapid, reliable and economic means of <br /> determining soil stratigraphy, relative density, <br /> r <br /> strength and equilibrium g q groundwater <br /> pressures. <br /> 1 <br /> Gregg In Situ offers a choice of 2.5, 5, 10 and <br /> 15 ton tip (Qc) capacity cones. Our cones <br /> also have variable capacity friction sleeves <br /> (Fs) and pore pressure (U). The pore <br /> Triaxial Geophones I pressure can be measured at one of 2 <br /> or Accelerometer ; locations, either on the face of the cone tip or <br /> (VP a vs) Y 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. Field data reduction, plotting <br /> r Thermistor{r) and CPT interpretation can be carried out f <br /> on u request. <br /> p <br /> :3 Friction Sleeve(F9) <br /> Load Cells <br /> Pore Pressure <br /> Porous Filter v `>{ Transducer(U) <br /> Element <br /> Cone Tip(Qc) <br /> f <br /> EGGGeotechnical and Environmental In Situ Testing Contractors <br /> Los Angeles • San Francisco - Houston • Aiken <br /> Vancouver • Edmonton • Salt Lake City • New Jersey <br /> Tel:(925)343-5800• Fax:(925)343-0302 • E-mail:gregg@ecls.com <br /> j <br /> f <br /> l <br />
