TR-10:
INSTALLING A TIE-BACK SYSTEM ON THE TOP OF A TIMBER SHEET PILING
WALL
Problem: The top of the timber sheetpiling wall has moved, lightly to moderately,
due to tie-back failure or excessive loading behind the wall. The area behind the
wall is inaccessible for repairs.
Description of Repair: Cast a new concrete slab with extra reinforcing, from the
face of the wall back behind the wall to the end of the existing slab. Tie the front
edge of the new slab to wall through use of a steel angle (see Figure 6-10).
Application: Limited. Additional restraint is limited to top of sheetpiling. If
excessive loading or loss of regular tie-back anchors are experienced, further
failure, including shearing of sheetpiling tops, may occur.
Future Inspection Requirement: Pay careful attention to wall inspection for
further signs of continued deflection or timber member failure.
