METHOD OF STABILISING WIND POWER INSTALLATION Russian patent published in 2017 - IPC E02D27/42 

FIELD: construction.

SUBSTANCE: invention relates to construction, specifically to stabilisation of a connection of a foundation section of a wind power installation. Disclosed is a method of stabilising a wind power installation, which comprises determining need for stabilisation of wind power installation relative to foundation, wherein determination includes measuring of movement of vertical support relative to foundation of wind power installation by using one or more sensors for change in length, located on at least one of windward and leeward sides of support of wind power installation, deactivating wind power installation, calibrating one or more sensors for change in length, activating wind power installation, measuring of movement of support and storing of data on measured movement of support, as soon as deviation values generated by one or more sensors of change in length is lower than a preset value, tracking position of nacelle of wind power installation during measurement of movement of support. Measurement of movement of support is interrupted, if change of position of nacelle is more than 5°. One or more sensors for measuring length on changed location windward side or leeward side support is are re-positioned depending on change of position of nacelle. Measurement of movement of support is started again. At least one section of surface of foundation of wind power installation is prepared, multiple holes are made in prepared surface at a given depth. Curable material is introduced into multiple holes and introduced material is cured in holes.

EFFECT: technical result consists in improvement of reliability of structure, reduction of material consumption and labour intensity of work on stabilisation of structure.
