- CFA Piling
Come on, someone on here must be an expert in CFA piles, surely?
My question is regarding the cage and how long it should be. I would only make it long enough to engage sufficient skin friction to resist any uplift, but the older generation want to put it all the way down. difference is 10m of cage (from 7m to resist uplift to 17m to go to the bottom) over 300 piles which is a lot of reinforcement.Posted 3 years ago
Just emailed you my thoughts, basically 8.3m assuming a cu of 70 in the clay. Forgot to add, but really you should also check bond capacity of the rebar to the concrete as well. Also, depending on the addition length this adds to your bending requirements, you could consider just using a central bar for tension.Posted 3 years ago
