Augercast Pile Reinforcement
Augercast Pile Reinforcement
(OP)
I am trying to resolve a debate with regards to the reinforcement of an augercast pile subjected to uplift and lateral loads. A search of previous posts seems to confirm the methodology I have always used: 1) provide a full length center bar sized to resist the uplift; and 2) provide a "column cage" to resist the bending moment (typically in the top 1/3 of the pier). My colleague is adamant that a full length "column cage" must be provided all the way to the bottom of the pier. I have never heard of this and do not believe it can actually be built that way. Any comments?

Although the technique is predominantly used with single-bar reinforcement, it is possible to insert a reinforcing cage into the auger as long as you have sufficient clearance. It is easier with bigger auger-cast diameters. Most often greater than 24 inches. However, I have seen it done with 18-inch diameter piles.
Another technique to get a full-length cage is to vibrate it down. However, it will need to be inserted within 10 minutes of completion of grouting. Even then, it is sometimes difficult to get the cage down.
