Ground Anchor

Double Corrosion Prevention
  • In the free section of the ground anchor, the steel strands are coated with anti-corrosion grease as the primary corrosion protection measure. The outer layer is then covered with high-density polyethylene (HDPE), providing dual-layer corrosion protection and excellent durability.
Re-tensionable
  • The ground anchor anchor section is made of high-strength alloy steel (SCM440) and is mechanically anchored in the factory, providing excellent gripping force.
  • The end anchor features a threaded nut locking design, allowing for easy pre-stressing adjustment and ensuring that the end anchor remains reliable and less likely to fail during an earthquake
Easy to Install
  • Manufactured in a factory setting, the finished product consists of a steel cable with threaded ends, making installation extremely convenient and significantly reducing assembly work on site.

  • PC steel strands are filled with anti-corrosion grease and coated with HDPE, implementing dual-layer corrosion protection.
B-B Sectional View-Anchoring Section
  • The PC steel strands are coated with cement grout mixed with non-shrink additives, and the anchor section is pressure-grouted to enhance anchoring performance.

Features

Corrosion-resistant Structure
  • Uses ground anchor protective covers and anti-corrosion grease for protection.
  • Pressure plates and nuts are hot-dip galvanized.
  • Rippled protective pipes and heat-shrink films are used to block water and harmful
  • During factory production, the anchor steel tube is pressed together with the HDPE coating material to ensure that the internal steel tendons are protected from moisture and corrosion.
