The attention to Pre-stressed steel strand anchorage
tensioning
The tensioning of the prestressed steel strand anchorage is carried
out in three stages: pre-tensioning, initial tensioning, and
intermediate tensioning. Please follow the steps below carefully:
1. The tensioning anchorage of the same bundle of steel strands
must be carried out simultaneously at both ends, and the main oil
steel of the jack is slowly filled with oil for tensioning, and the
reading of the oil meter is the main factor, and the elongation
value of the steel strand is checked. The difference between the
actual elongation value and the theoretical elongation value is
controlled within plus or minus 6%. The difference between the
elongation of the steel strands at both ends should not be greater
than 5%, and it is strictly forbidden to stretch one end. The steel
bundles that are tensioned at one time are controlled by double
control. For the steel bundles that are stretched twice, the
elongation value should be used for compounding in the first-stage
tensioning, and the tensioning force value should be used for the
second-stage supplementary tensioning. Elongation values are
recorded on time.
2. The box beam is moved and stored. A 900-ton tire-type beam
lifter is used to lift and move the box beam to the beam storage
area, and the beam storage platform is aligned. The beam storage
area adopts double-layer beam storage.
3. Hole grouting. Prestressed pipeline grouting adopts a
vacuum-assisted grouting process. Continuous grouting with screw
grouting pump, when the concentration of the slurry flowing out of
the grouting nozzle is consistent with the concentration in the
grouting pump, connect the grouting port of the pipeline, and open
the valve of the grouting port for grouting. When the slurry passes
through the transparent tube, the valve of the exhaust port of the
vacuum pump can be closed. When the consistency of the slurry
flowing out of the exhaust pipe is the same as before filling, the
exhaust valve can be closed and the slurry can be continuously
pressed. After raising the pressure in the pipeline to 0.50-0.60
MPa, apply pressure for 3 minutes and close the grouting valve. The
grouting of the same pipeline should be carried out continuously
and completed at one time.
Warm tips About Multi strands Anchor
1. The anchors should be kept properly, and there should be no
rust, water, and other sundries in use.
2. Apply lubricant on the outer surface of the tool clip and the
inner surface of the taper hole of the anchor plate before use, and
often remove the debris on the surface of the clip.
3. Safety measures should be taken during tensioning, and no one
can stand after the tensioning jack.
4. The anchor system should be used together and cannot be mixed
with other systems.
