Anchored Tubular Piles

[ItsOnlyDirt]

Hi All

I'm looking at a marine retaining wall which at outline design is to be anchored to an anchor wall by tie rods. I'm trying to come up with a more construction efficient solution such as anchors into the rock at say 30degs. Does anyone have any experience they are willing to share?

Cheers Guys

Anchoring to rock will work and has been done often. Rock anchors are very dependaple. They should be corrosion protected permenant anchors. Waler will need to be set at a 30 deg angle also. The anchor will induce vertical load in the sheeting which will need to be accounted for in the design. If you have a signfican soil fill you can use stand anchors. If you do not have any backfill or tensioning the anchors would cause a problem, you could use bar anchors, which will cost more than the strand.
overall it is a feasible concept. A local tie back installer could probably give you a lot more detail.
