Helical Anchors
Helical Anchors
(OP)
We are thinking of using helical anchors to hold down a temporary structure being installed on an existing parking structure. The uplift loads are 1,500 to 2,000 pounds. Chance anchors will work but the capacities are much large than I need. What anchors would you use in this applicacation?

For example, this type of place.

Or, yeah, just bury a pipe or a board or something

Perhaps a picture of what your doing?

Helical anchors are basically soil augers used as tension anchors or, in the case of larger ones, piles.
Traditional helical anchors are either rods or square bar with a helix on the end that are driven by hand or mechanically into the ground. They're great for things like guyed structures where you're only going to see tension loads. They're quick to install and relatively cheap.
In the last decade or so helical *piles* have gotten popular in some places. They're effectively pipe piles with a helix or two welded to the bottom. They're great in compression and tension and go in really really fast. They're installed using a screw head that's normally installed on an excavator or some sort of truck mounted crane. You can also install them in fairly tight spaces and where things like driven piles wouldn't work because of the impact.

If I owned a parking lot, I wouldnt want those drilled thru it, but perhaps that doenst matter.
