Hybridanker aus UHPC - Erstanwendung bei der Verstärkung der Rheinschleuse Iffezheim mit Dauerlitzenankern

First application of composite anchor plates ("Hybridanker") for strengthening a Rhine lock with permanent ground anchors

Prefabricated composite anchor plates are using high performance concrete and steel or carbon fibres for load transfer of tendon forces (post-tensioning tendons, ground anchors). First application of the Hybridanker-type has been realized at the Rhine lock in Iffezheim, where permanent multistrand ground anchors had been installed. The prefabricated Hybridanker-solution allowed a durable and compact load transfer to old, unreinforced concrete.
