0 10 <br /> SimulProbe®Technologies, Inc. <br /> Maxi SimulProbe®Soil/Groundwater Mode <br /> 3.0 ASSEMBLY AND OPERATION: Soil/Groundwater Mode - Using <br /> Nitrogen Back Pressurization With Groundwater Canister and Cased <br /> Hole or Mud Rotary Drilling Applications <br /> 3.1 Place clean Teflon Tubes along the slots in the edges of the Core Barrel <br /> Primary Half and push Teflon Tubes into the fluid pathway holes at the top <br /> of the slots. The lower end of the Teflon Tubes should end about 1/4 inch <br /> short of the lower end of the slots. <br /> 3.2 Insert a reed valve into the Core Barrel Primary Half fluid displacement <br /> port at top of the Core Barrel. <br /> 3.3 Place 3 Core Sleeves into the Core Barrel Primary Half. <br /> Note: Do not use standard 6"-long core sleeves as they will not <br /> allow the SimulProbe® Drive Shoe to fully close. (STI <br /> Maxi SimulProbe core sleeves are 5 and 13/16 inches long.) <br /> 3.5 Place the Core Barrel Cover Half over Core Barrel Primary Half, making <br /> sure that the Teflon Tubes are in the grooves between the core barrel <br /> halves. <br /> 3.6 Clamp the core barrel halves together using the chain vise on the driller's <br /> breakdown rack. This allows the Coupling to be easily screwed into <br /> place. <br /> 3.7 Place the Circular Screen over circumferential channel and fluid entry <br /> ports at the bottom of core barrel. The circumferential channel is the <br /> channel on the outside of the core barrel halves just above the threads to <br /> which the Coupling is later attached. <br /> 3.8 If using the Maxi SimulProbe@ Drive Shoe Extension Assembly, then in <br /> addition to the Circular Screen, you will also use the 4-inch Extension <br /> Screen. The Extension Screen is first slid onto the grooved Extension <br /> Coupling until is seats against the raised lip at the down-hole end of the <br /> Extension Coupling. The Extension Coupling is then screwed onto the <br /> bottom threads of the Maxi Core Barrel. As you screw on the Extension <br /> Coupling and Screen, you will notice how the Extension Screen rotates <br /> over the Circular Screen — providing a double filter to the Fluid Entry Ports <br /> near the base of the Maxi Core Barrel. Assemble the remaining parts of <br /> the Drive Shoe Extension Assembly as you would for the Short Maxi Shoe <br /> Assembly (Sections 3.9 through 3.12). If you are not using the Drive <br /> Shoe Extension Assembly, then continue on to Section 3.9 below. If you <br /> are using the Drive Shoe Extension Assembly, then continue to Section <br /> 3.11. <br /> 3 <br />
