Passive anchor solution for slope stabilization
A Passive Anchor is not pre-tensioned. Applied loads are transmitted from the ground or ground structure directly. A passive anchor does not usually have a free (unbonded) length of tendon.
A typical application for Passive Anchors is the stabilization of soil-covered slopes, which are constantly moving due to gravity. In that case Passive hors are inserted from the face of slope into the stable ground and grouted to provide preventive anchoring in case the soil starts moving.
About our ASTEC FRP soil nail
- For temporary applications, take advantage of the cuttable nature of FRP bars. At the end of the project, the anchor doesn’t need to be removed from the ground, as it can be cut by standard earth moving equipment or Tunnel Boring Machines.
- 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.
- Splicing system: Dextra provides a unique splicing system allowing to splice FRP bars to achieve longer tendon length.
- 4 bar/anchor diameters available for an ultimate tensile load up to 770 kN.
- Designed as per ACI 440-4R-04; FHWA-IF-03-017; FHWA-SA-96-069; HK GEOGUIDE 7; ISO 6934-4.
