Foundation Anchor Plate

Wind Turbine Anchor Plate for foundation has 2 parts: upper and lower anchor plate(embed and template ring), which are connected by splice plates and high strength anchor bolts. Splice plate is a kind of rectangle plate which has the same mechanical properties of anchor plate, usually wind turbine foundation requires anchor plate with large diameter, compared with manufacture anchor ring plate in hot rolled method, use splice plate and seperate parts of anchor plate is more economical option.

There are many factors can influence the wind tower foundation configuration, wind turbine size and brand, site geotechnical conditions, etc. Wind tower cage foundation structure has to with stand compressive and uplift forces caused by strong wind forces. Before construction, investigation and research of structural and geotechnical design checks are needed.
