Construction—EMEA—Great Britain—Structural Repair Solutions
Additional supporting anchorage points were
arranged at mid flange, and at the lower end,
termination points served to stabilize the
underside cradle.
In addition to the fully threaded coarse thread,
the advantage of the GEWI ® System was that
the threadbars could be bent in the lower bar
section. While the old ties were being replaced
by the new GEWI ® Tie Rods, DSI stabilized
the sewer pipes using temporary tendons.
These tendons were equipped with load cells
to monitor the load in the sewer barrels.
DSI also developed a precise loading
sequence to ensure progressive load
transfer between the old and the new tie
rods. The temporary tie rods resting on the
top girder had different vertical inclinations.
Consequently, special rocker plates were
required to place the load cells in line on
each tendon.
