I intend to take advantage of winter and the 3 feet deep cover of ice over the lake to install three helix screws, as part as a mooring
. The depth
under the ice is 6 feet of water
. There is silt or mud in the bottom at 240 feet from the shore of the lake. The width of the lake is about 6 km. Next to the shore there is too much rocks or gravel to be able to insert the helix anchors.
The stability of ice support should facilitate the operation of screwing the helix anchor
into the bottom. Each helix is said to provide 1500 pounds for exposed area, see table:
The helix anchor
that I will be using are made of galvanized steel
58 inches long, 3/4 inch rod and 6 inches helix. They come at a very low price
, being used in the production of grapes.
I would like to use preferably an eco-system device.
I would like to instawll them with a modified version of the following proposition using a 4 inches PVC tube to drive the screw into silt, but in summer:
1) Has there been any such type of attempt by some of this forum members to install helix anchors? I am thinking about setting my three helix anchors at short distance (2 feet) and to tie them together with 3 less than two 3/4 inch galvanised chain and a schackle that will in turn be tied to a unique line to buoy with a conventional chain and rope
; or with a stretching system. Is this the way to go?
2) How could I find my helix anchors this spring after the recession of the ice cover? Can I put a small floating buoy attached to the anchor under the ice or simply plant a stick under water
and under the ice, or should I resort to some sort of gps
tracker or radio
tracker to be able to find my helix anchor? Is there a cheap
way to do this? Water is turbid all around year, such that some underwater tag has very little chance to be seen from the surface.
Thanks for breaking your brains on this problem.
