AI Technical Summary

Technical Problem

The existing anchoring methods for wind turbine tower foundations have insufficient bonding strength, which makes them prone to loosening, especially under long-term alternating loads and wind-induced vibrations. In addition, the bonding strength between the upper anchor plate and the grouting material is insufficient, resulting in unsatisfactory anchoring effect.

Method used

The multi-segment joint burial structure design includes upper and lower stabilizing kits, distributed inclined anchor bolts and radial anchor bolts, forming a multi-layered inverted anchoring structure. Combined with anchoring components and waterproof sealing coating, it enhances the adhesion and pull-out resistance between the studs and the grouting layer.

Benefits of technology

It significantly improves the overall stability and anchoring reliability of the wind turbine tower foundation, prevents loosening and displacement under long-term alternating loads, and extends the service life of the equipment.
