Ils peuvent être utilisés aussi bien dans des applications temporaires que permanentes, ce qui les rend polyvalents et adaptables pour répondre aux besoins de votre projet.
Solution d'ancrage post-tendue en FRP
Active anchors are 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.
ASTEC active anchors is made of composite material, which is by nature cuttable. The tendons can be excavated by any standard equipment, therefore anchor removal is never required.
Solution d'ancrage passif pour la stabilisation des pentes
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 anchors are inserted from the face of the slope into the stable ground and grouted to provide preventive anchoring in case the soil starts moving.
