The CPTU provides ; <br /> ` M a rapid, reliable and economic means of ' <br /> determining soil stratigraphy, relative density, <br /> strength and equilibrium groundwater <br /> pressures. <br /> 4 <br /> f. Gregg In Situ offers a choice of 2.5, 5, 10 and <br /> a uF <br /> . vs <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 pressure can be measured at one of 2 <br /> or Accelerometer locations, either on the face of the cone tip or <br /> (Vp&Vs) 54 <br /> behind the cone tip. Pore pressure <br /> . :" . dissipation data is recorded automatically. <br /> � I <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 /> Thermistor(T) and CPT interpretation can be carried out <br /> upon request. <br /> Friction Sleeve(Fs) <br /> Load Cells <br /> A <br /> 1 <br /> Pore Pressure <br /> M Porous Filter ,;r -' Transducer(U) <br /> Element <br /> F Cone Tip(Qc I <br /> EGGGeotechnical and Environmental In Situ Testing Contractors <br /> Los Angeles • San Francisco • Houston • Aiken <br /> Vancouver • Edmonton - Salt Lake City • New Jersey <br /> 1 <br /> Tel.(925)313-5800 Fax.(925)3134)302 E-mail.gnegg@eds.com <br /> f <br /> f <br /> II <br />
