EGG Cone Penetration Testing Procedure <br /> (CPT) <br /> Gregg In Situ, Inc tames out all Cone Penetration Tests (CPT) using an <br /> integrated electronic cone system, Figure CPT The soundings were conducted <br /> using a 20 ton capacity cone with a tip area of 15 cm2 and a friction sleeve area <br /> of 225 cm2 The cone is designed with an equal end area friction sleeve and a <br /> tip end area ratio of 0 85 <br /> The cone takes measurements of _ <br /> cone bearing (q j, sleeve friction (f$) Geophones <br /> and dynamic pore water pressure (VS&VP) C <br /> (u2) at 5-cm intervals during <br /> penetration to provide a nearly Push rod <br /> continuous hydrogeologic log CPT connector <br /> data reduction and interpretation is <br /> Soil seal <br /> performed in real time facilitating on- <br /> site decision making The above Electric cable for <br /> mentioned parameters are stored on ��Vter-SP-M- <br /> reeUe—renec- <br /> nal transmission <br /> disk for further analysis and <br /> -AN-CPT s�ndi�r�— -- <br /> performed in accordance with Friction load cell <br /> . revised (2002) ASTM standards (D Frictin sleeve <br /> 5778-95) Inclinometer <br /> The cone also contains a porous ox&�) <br /> filter element located directly behind Tip load cell <br /> the cone tip (u2), Figure CPT It <br /> consists of porous plastic and is <br /> 5 Omm thick The filter element is Water Seal <br /> used to obtain dynamic pore <br /> pressure as the cone is advanced as „ Soil seal <br /> well as Pore Pressure Dissipation r, Pore Pressure <br /> Tests (PPDT's) during appropriate Transducer (UQ) <br /> pauses in penetration It should be Tip load cell A Filter <br /> noted that prior to penetration, the <br /> element is fully saturated with silicon In Tp (qc) <br /> oil under vacuum pressure to ensure <br /> accurate and fast dissipation F�yure GPT <br /> When the soundings are complete, the test holes are grouted using a Gregg In <br /> Situ support rig The grouting procedure consists of pushing a Hollow CPT rod <br /> . with a "knock out" plug to the termination depth of the test hole Grout is then <br /> pumped under pressure as the tremie pipe is pulled from the hole Disruption or <br /> further contamination to the site is therefore minimized <br />
