In severely corrosive environments, the anchor rod in the anchoring section of the anchor rod needs to be wrapped with a corrugated pipe, and the pores inside the pipe should be filled with cement slurry or epoxy resin. The thickness of the protective layer around the sleeve should not be less than 10mm.
When the permanent anchor rod adopts an exposed head, it needs to be coated with anti-corrosion materials such as asphalt, and then sealed with concrete. The thickness of the protective layer of the exposed steel plate and anchor should not be less than 25mm.
When a permanent anchor rod is sealed with a box, lubricating oil needs to be used to fill the gaps inside the box.
In general corrosive environments, permanent anchor rods can be sealed with mortar or cement slurry for corrosion prevention within the anchoring section of the anchor rod, but a 20mm thick protective layer is required around the rod body.
So everyone, the above is the little knowledge about anchor rods that we introduced today. Have you understood it all.
