Active Anchors
FRP post-tensioned anchoring solution.An Active Anchors is post-tensioned from the external face of the ground immediately after installation, and is usually designed to help prevent deformation of the ground or retained structure. It has a free length and a bonded length.
A typical application for Active Anchors is anchoring of retaining walls during excavation works. To prevent the wall from the smallest displacement, the anchor is pre-loaded.
CurlF Active Anchors is made of composite material, which is by nature cut-able. The tendons can be excavated by any standard equipment, therefore anchor removal is never required.
Multi-tendon: from one to 14 tendon. Each FRP tendons is spliced to a standard PT strand in sleeve (no friction for the free length) which can be tensioned with standard jack equipment.
Lightweight
¼ the weight of steel
High Tensile Strength
Twice the strength of steel
Non-magnetic
No interference with sensitive enquipment
Whole of Life Savings
Design life cycle is 100 years
Zero maintenance cost
Easy to cut and install
Cut on-site using standard cutting tools. Bends delivered preformed
Corrosion Free
Exceptional resistance to water and salinity.
Does not rust or leach
Highly Chemical Resistant
Exceptionally resistant to a range of chemicals
Low Environmental Impact
Consumes approximately 70% the embodied energy of steel
Easy to cut
FRP can easily be cut out: no extraction required, even in neighboring plots. Save on anchor removal costs. For temporary applications, take advantage of the cuttable nature of FRP bars. At the end of the project, anchor doesn’t need to be removed from the ground, as it can be cut by standard earth moving equipment or Tunnel Boring Machines (subway projects).
CurlF FRP cable strand are easy of cutting, reduces time, labor, and risk; cutting steel necessitates extra effort and strict fire safety measures.
Transport Savings
1/4 the weight of steel for equal volume, composite cable strand are more economical to transport. Quicker to unload when it arrives on-site.
Rust is the biggest enemy of metal
FRP cable strand never rusts
Never corrosion
FRP cable strand exceptional resistance to water and salinity.Does not rust or leach. For permanent applications, the full resistance of the FRP anchor to corrosion will guarantee optimal performance over the years. No additional corrosion protection accessories required.
The finished Cable strand very flexible and easy to transport
CurlF FRP cable strand more than 100 meters per roll
FRP post-tensioned anchoring solution performance index
Application
Support of deep foundation pit，Posttensioned soil layer fixed. Combined use：Composite material anchor cable and TBM door.
