EGG GREGG IN SITU, INC. <br /> 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 /> 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 /> 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) 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 /> Thermistor(T) malting process. Field data reduction, plotting <br /> and CPT interpretation can be carried out <br /> upon request. <br /> Friction Sleeve(Fs) <br /> Load Cells <br /> M Pore Pressure <br /> Porous Filter Transducer(U) <br /> Element <br /> I Cone Tip(Qc) <br /> i <br /> EGG Geotechnical and Environmental In Situ Testing Contractors <br /> i Los Angeles • San Francisco • Houston • Aiken <br /> j.
