Geotechnical rig systems and methods
This invention relates generally to geotechnical rig systems and methods. In one embodiment, a cone penetration testing system includes, but is not limited to, a frame; at least one rotatable reel; at least one movable roller, and at least one sensor, wherein the at least one movable roller is configured to adjust a bend radius of at least one tube coiled about the at least one rotatable reel based at least partly on data received from the at least one sensor.
1. A rig comprising: a frame; cassette, the cassette including: a reel that is configured to rotate within the cassette; an opening in a sidewall, the opening being laterally offset from the reel and the opening along its width being perpendicular to an axis of rotation of the reel; at least one tube having a cone penetration testing head, the at least one tube being coiled on the reel within the at least one cassette and configured to uncoil via the opening in the sidewall; and a guide channel configured to direct the at least one tube when uncoiled via the opening.
2. The rig of claim 1 , further comprising:
at least one continuous track propulsion system.
3. The rig of claim 1 , wherein the at least one cassette is removable.
4. The rig of claim 1 , further comprising: a funnel mount, the funnel mount configured to guide the cassette into position.
5. The rig of claim 1 , wherein the guide channel facilitates retraction and/or extension of the at least one tube relative to the reel.
6. The rig of claim 1 , further comprising:
at least one camera.
7. The rig of claim 1 , further comprising:
at least one proximity sensor.
8. The rig of claim 1 , further comprising:
at least one contact sensor.
9. The rig of claim 1 , further comprising:
at least one roller.
10. The rig of claim 1 , further comprising:
at least one radius control system.
11. The rig of claim 1 , further comprising:
at least one processor configured to control a position of at least one movable roller relative to the at least one tube based at least partly on a detected bend radius of the at least one tube.
12. The rig of claim 1 , wherein the cassette includes a circumference wall that at least partially encloses the reel.
13. The rig of claim 1 , wherein at least one sensor is positioned on an inside surface of the cassette to detect bend radius information associated with the at least one tube.
14. The rig of claim 1 , wherein the cassette lockably engages one or more mating recesses of the rig.
15. The rig of claim 1 , further comprising: at least one drive system configured to extend or retract the at least one tube from the cassette.
16. The rig of claim 1 , wherein the guide channel is offset from the cassette and bends the at least one tube in a plane that is offset from the cassette.
17. The rig of claim 1 , wherein the guide channel is offset from the cassette and includes at least one movable roller to adjust a bend radius of the at least one tube in a plane that is offset from the cassette.
18. The rig of claim 1 , wherein the guide channel is offset from the cassette and includes (i) at least one sensor configured to obtain information regarding shape of the at least one tube and (ii) at least one movable roller that adjusts based at least partly on the information regarding shape of the at least one tube.
19. A device for cone penetration testing, the device comprising: a cassette with a rotatable reel, the cassette including at least: an opening in a sidewall, the opening being laterally offset from the rotatable reel and the opening along its width being perpendicular to an axis of rotation of the reel; and tubing having a cone penetration testing head, the tubing being coiled within the cassette on the rotatable reel and configured to uncoil via the opening; and a guide channel configured to direct the tubing when uncoiled via the opening.
20. A device for cone penetration testing, the device comprising: a cassette including: a rotatable reel for tubing, an opening in a sidewall configured to pass the tubing, the opening being laterally offset from the rotatable reel and the opening along its width being perpendicular to an axis of rotation of the rotatable reel, and at least one dock that releasably couples to a rig.
