Problems solved by technology

Due to the dynamic loads of the wind energy installation, due to faulty installation or insufficient hardening of the foundation material, in the case of an increasing service life of the wind energy installation, a greater degree of erosion of the foundation material surrounding the foundation section can occur loose, and thus movement gaps and crack formation
As a result, the stability is compromised in the event of a reduced force fit between the base section and the base

Embodiment Construction

[0041] The method starts in step 1. Thereafter, the wind energy installation is first deactivated as step 3. In step 5, one or more length change sensors are optionally mounted on the tower wall or on the foundation of the wind energy installation and connected to the other parts in each case. Additionally, one or more length change sensors are calibrated in step 5. In step 7, the wind speed is determined. Optionally (not shown), the determination of the wind speed is carried out in the still active wind energy installation, and when a wind speed greater than or equal to 7.5 m / s, preferably greater than or equal to 10 m / s is measured in step 9, then Only deactivate the wind energy plant according to step 3. If a speed of less than 7.5 m / s or preferably less than 10 m / s is determined, in step 7 the determination of the wind speed is continued.

[0042] If there is a sufficiently high wind speed and the wind energy installation is disabled, then in step 11 the wind energy in...

Abstract

The invention concerns a method of stabilizing a wind power installation, in particular the connection of a foundation section of the wind power installation to the foundation of the wind power installation, including the steps: performing a stabilization measure, including pre-preparation of at least a portion of the surface of a foundation of the wind power installation for the application of boring means, introducing a plurality of bores by means of the boring means in the pre-prepared surface to a predetermined depth, preferably to an anchor segment of the foundation section, introducing a hardenable material into the plurality of bores, hardening the introduced hardenable material in the bores, and post-preparation of the at least one portion of the surface of the installation foundation. The invention concerns in particular a method of stabilizing a wind power installation including early identification of the need for stabilization of the wind power installation by means of measurement of the pylon movement during operation of the wind power installation.

Description

technical field [0001] The invention relates to a method for securing a wind energy installation according to the preamble of claim 1 . The invention therefore relates in particular to a method for securing the connection of a foundation section of a wind energy installation to a foundation of a wind energy installation, comprising the step of performing a securing measure comprising bonding at least one of the surfaces of the foundation of a wind energy installation Section preparation is used to accommodate the drilling mechanism, a plurality of holes are introduced into the prepared surface by means of the drilling mechanism to a predetermined depth, preferably up to the anchoring section of the base section, the hardenable material is introduced into a plurality of holes, harden the introduced hardenable material in the holes, and prepare at least one section of the surface of the device base again. Background technique [0002] With regard to priority applications, ref...
