anchor tie

If you wanna tie anchor to it and drop it right into the ocean, that's no problem, because plant fibers can stand up for months, even years, in direct contact with salt water.

A better suggestion would be the Pratt knot, a very easy to tie knot popularized by news anchor Don Shelby.

The steel anchor box of the tie ho arch bridge has the characteristics of carrying lug loads and fitting into a small space. This adds to the difficulties in design and production.
