An anchorage system

摘要

600859 Disclosed are an anchorage system (1) and a method for installing an anchorage system (1). Present anchorage systems using steel tendons are susceptible to corrosion therefore double corrosion protection systems used to prevent corrosion alter the physical properties of the tendons. The anchorage system (1) comprises a composite tendon (2). The composite tendon (2) comprises an assembly of elongate elements are held together. The assembly of elongate elements include a primary wire (4) and a plurality of secondary wires (5) wound around the primary wire (4). The individual elongate elements are separated from each other at one end extending into the anchor head. The anchor head casing (6) is filled with an adhesive medium (10) to secure the separated elements in the casing (6). The anchorage system (1) is installed by inserting at least one composite tendon (2) comprising the assembly of elongate parts into a borehole (20). The individual elongate members are separated from each other along the length of the anchor head (22). The anchor head casing (6) is placed around the separated elements. The anchor head casing (6) is filled with an adhesive medium (10) which secures the separated elements into the anchor head.
