• Ground dowels have long been known in a variety of forms, e.g. from DE 200 00 182 U1. They serve both for temporary support of posts and masts in the ground, such as e.g. the posts of clothes dryers, umbrellas and the like, which are removed again after use from the ground anchor, while the ground anchor itself remains in the ground, as well as for permanent attachment e.g. of fence posts, lights and smaller wind turbines and solar panels.
