In geotechnical anchorage engineering, there are three anti-corrosion systems according to different soil environments and engineering service life. The systems are based on the refined rolled thread bar, matched with centralizer, corrugated pipe, end cap, smooth plastic pipe and so on.
– Class I Anti-corrosion System
Class I anti-corrosion anchoring system is suitable for semi-permanent support and permanent support in corrosive environment. Anchorage section is protected by corrugated pipe, end cap, cement grout, and the free section is protected by smooth plastic pipe.
– Class II Anti-corrosion System
Class II anti-corrosion anchoring system is used for temporary support in corrosive environment and semi-permanent support in non-corrosive environment. Anchorage section is protected by cement grout, and the free section is protected by smooth plastic pipe.
– Non-anticorrosive System
Non-anticorrosive anchorage system is suitable for temporary support in non-corrosive environments, and cement grout will protect the anchoring section.
