EGG GREGG IN SITU, INC. <br /> I!•■�II!• Geotechnical and Environmental In Situ Testing Contractors <br /> THE PIEZO 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 /> {` 4, determining soil stratigraphy, relative density, <br /> strength and equilibrium groundwater <br /> pressures. <br /> til <br /> Gregg In Situ offers a choice of 2.5, 5, 10 and <br /> :c 15 ton tip (Qc) capacity cones. Our cones <br /> also have variable capacity friction sleeves <br /> \f; <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&vs) 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 /> Thermistor(T) and CPT interpretation can be carried out <br /> :,h< <br /> upon request. <br /> Friction Sleeve(Fs) <br /> Load Cells <br /> I ,I' <br /> gl <br /> Pore Pressure <br /> Porous Filter <br /> Transducer(U) <br /> Element <br /> °5 Cone Tip(ac) <br /> }' l <br /> "EG Geotechnical and Environmental In Situ Testing Contractors <br /> Los Angeles - San Francisco • Houston • Aiken <br /> Vancouver • Edmonton - Salt Lake City - New Jersey <br /> Tel:(925)313-5800• Fax:(925)313-0302 - E-mail.gregg@ecis.com <br />
