Anchoring of tension members

摘要

By using a packer which is pushed as far over an anchor as the intended length of the moulding, the cavity in a borehole in the region of the bond can be completely filled with a reactive resin. Overhead work is possible even with slowly reacting resins. By using a catalyst on the packer, the reactive resin injected into the borehole behind the packer can be made to harden very rapidly.
