Steel Sheet Pile Wall
Steel Sheet Pile Wall
(OP)
I have situation where the Permanent sheet pile wall has a tie back system, Contractor wants to know: How the anchor bar will be tensioned? Either indirectly by placement of the backfill or by direct application of some predefiend tension or torque before backfill placement?





RE: Steel Sheet Pile Wall
Tiebacks are stressed using a center-hole, hydraulic jack with a calibrated pressure guage and sometimes a load cell. The tiebacks are not supposed to be stressed by movement of the wall when backfilling.
It is also a very bad idea to place backfill over a bar tendon. This can cause bending of the tieback bar tendon which adds a stress for which the tendon was not designed and which can cause tendon failure. If too much fill is placed before the tieback anchors are installed and stressed, the sheet pile wall will move forward excessively. If the tiebacks are stressed before
If neither you nor the contractor know the answer to the question, then neither of you should be designing or building the wall. You should have an engineer and a contractor who are experienced with tiedback walls.
