Anchorages
Anchors as ties serve to transfer loads from earth and water pressure or wind pressure into bearing soil layers further away. Depending on the period of use, one differentiates between permanent, semi-permanent or temporary anchors. The anchors can consist of single strands or a single rod which is installed in the drill hole. For this, by the precise injection of cement mortar, a grout body is created which takes over the transfer of loads to the building ground. Once the cement mortar has hardened the anchor is prestressed to limit deformations. By using special sealing constructions during the drilling and installation of the anchors, they can also be installed while being exposed to extremely high groundwater pressure and without any of the soil behind the retaining wall being washed out. Temporary anchors can be removed after use.
