Temporary ground anchor

[Junkwisch]

Hey guys, can anyone tell me the process of distressing ground anchor? In construction, we use some kind of machine that pulled tendon from an open end. I assumed that this method is also work for installation of temporary ground anchor, is this correct? But how do we release the stress? do we simply cut the reinforcement etc?

One more question, there is no difference between soil nail and ground anchor, is this correct?


Thanks

Soil nails and tieback anchors have similarities and differences. They behave differently and generally have different yield strengths, lengths, and design loads. All tieback anchors should be tested. Not all soil nails are tested. Search for other threads in Eng-Tips.

Usually, after the backfill in front of an anchored wall reaches the elevation from which the anchors were installed, the anchors can be detensioned. The steel anchor tendon should slowly be heated to relax/release the tension. Then after the tendon has stretched to relax/release its load, the tendon can be cut with the torch. Never stand behind the tendon while stressing or destressing an anchor.
