Of course there is always the question - "you can actually tighten the anchor into the ground" - And of course the answer is Jain, because there are countless types of soil. I knew I had a rocky, superhard clay; so I chose the "long version" of the anchor and a piece to replace ordered separately. Fact is, the steel rod is thick enough and the slope of the coiling is actually far enough. The slope of the coiling is namely the measure of the diameter stone in the soil, which can be overcome when turning. The stones are pressed when screwed to the side or migrate through the filament. With thick "Wacken" but it's over. Since I was "warned" I proceeded as follows: I have worked with the spade on each Eindrehstelle spade depth = 30 cm excavated as wide dasss I could stand with both feet in the hole. Then I watered soften to the ground. After sufficient soaking time I screwed the first coiling and then put me on the upper spiral, so that the anchor and furled and not only loosens the soil. To turn I put the tip of my carpenter hammer through the eyelet. In "resistance" often helped "front-back pre-rotation" the. Was right at the start of rotation of the resistance is too large, then I again hurried along with the spade and stones away over fist size. So I have installed 6 anchor and reached in 5 of 6 my "target depth" and then the hole again filled (anstampfen). Since the coiling is wide enough to sit firmly anchor all, despite the "Spade Vorgrabung". Because spare anchor I have not needed. The double swing is now claimed by 2 "Swing Kids" and everything is clear reassuring. In summary, the Eindrehanker for normal handyman is a possibly sweaty but extremely cost-effective alternative. It's certainly faster than any Einbetoniervariante and the later demolition in X years has it easier.
