:Prestressed Augercast Soldier Pile
(OP)
Anyone have any success or experience in using a special design of Sequentially Prestressed Augercast Soldier Pile instead of the normal wide flange sections or tiebacks, including soil nailing?
Have a project where no tiebacks can be used and I am trying to minimize, or eliminate entirely, the use of interior rakers in the pit - three to four story cut.
I anticipate gradually prestressing the piles with multiple tendons, strategically placed in the 30" diameter pile, as the excavation progresses to avoid tension in the concrete, enabling the use of the Gross I section for lateral deflection.
Any thoughts?

If you are in the US, we have found VSL's Houston office to be quite helpfull on a lot of issues involving prestressing/post-tensioning.

Also, just for your information, I believe the piles typically have a single, central, debonded prestressing cable and rather than a group. If you like I can have a word with a buddy in Geotechnical group and see what he says.

Yes, could you please - our geotech has not heard of such an application, yet. And he is very experienced - could be the economics here. Nevertheless, I want to know oneway or the other. Thanks.

Sorry, I should have warned you, but this is a long week-end in NZ. I've just checked my posts and seen your's now... I'll talk to one of the boys tomorrow and let you know.
