Specimen removal in the triaxial cell configuration
1. When the test is complete, turn the HSM off.
2. Open the door and remove the bolts attaching the triaxial cell pushrod to the
actuator rod.
3. Close the door, turn the HSM on and retract the actuator.
4. Turn the HSM off.
5. Drain the confining fluid out of the triaxial cell.
6. Disconnect the confining and pore pressure lines.
7. Disconnect the transducer ID and system transducer cabling.
8. Remove the locating stop from in front of the triaxial cell.
9. Slide the triaxial cell out along the rails.
10. Use the spring-loaded retention pins to hold the locating plate to the rails.
11. Attach the lifting crane to the triaxial cell.
Note To release the lifting cable, it may be necessary to pull on the end while
turning the crank counterclockwise.
12. Apply a lifting load to the bell of the triaxial cell.
Note Seal pressure may require using three jacking screws in the base of the
cell to help the triaxial cell bell separate from the baseplate.
13. Move the bell of the tri-axial cell off to the side and lower it to a safe
position.
14. Remove the specimen.
15. Remove the extensometers from the specimen, and insert the zero pins. The
zero pins help protect the extensometers from inadvertent over-travel.
