FRP grating Precautions

  PUBLISH：2014-3-1

1, due to the density of small, light material, easy to install fiberglass grille float tube in high water table areas, must be considered to set the town pier or divert stormwater runoff measures such as anti-floating.
2, has been installed in the fiberglass grille opening tee, pipe repair cracks in construction, requirements similar to the plant completely dry conditions and the construction and the use of resin curing fabric needed 7-8 hours, and on-site construction and Repairing generally difficult to meet this requirement.
3, the existing underground pipeline detection equipment to detect metal pipes mainly based, and non-metallic pipe detection equipment is expensive, and therefore can not be detected after FRP grating buried, other subsequent construction units can easily dig in construction injuries, damage to the pipeline.
4, FRP grating UV poor. Surface mounted FRP grating by resin-rich surface layer produced 0.5mm thick and UV absorbers (processing plant), to slow down the aging time. Over time operation, the resin-rich layer and the ultraviolet absorber to be destroyed, thus affecting its life.
