Method for re-hardening of dual-T-profile, which is utilized for anchoring tower of wind energy system, involves awaiting hardening time of filling agent, and releasing anchor element by retaining forces after lapse of hardening time

摘要

The method involves lifting out of an anchor element (1) from a lower tolerance end position using a press (5) i.e. hydraulic press, and holding the anchor element in the position. A hollow space (3) is filled with a filling agent, which comprises a synthetic resin via an injection method. A hardening time of the filling agent is awaited, and the anchor element is released by retaining forces after lapse of the hardening time of the filling agent. The anchor element is pressed against contact surfaces that define the tolerance end position.
