pre-cast concrete piles
pre-cast concrete piles
(OP)
I'm looking into different options for my pre-cast piles.
One is by using pre-stressed concrete piles and the other is by conventional (using rebars only) reinforced concrete piles. Both piles are designed to maintain the required capacity.
Specifically, I would like to know:
a.)Advantages and disadvantages between the two schemes.
b.) Would the method of driving differ between the two schemes?
c.) Would it be advantageous to use pre-stressed? In what way?
Hope for your prompt reply. Thanks.

RE: pre-cast concrete piles
By the 1950's better highways & larger trucks made delivery of prestressed products practical.
Precast piles had a tendency to crack (no tension strands to "squeeze" the concrete together). Of course this could allow water to enter to corrode the rebar.
One seldom used, but unique advantage of a precast pile, was the opportunity to include an axial steel pipe in the pile interior. Then, in sandy soil, all the contractor had to do to jet the pile was to connect a pump to the pipe.
Even I am not old enough to remember all this first hand, but did grow up in a bridge building family, and recall as a small boy seeing the last days of concrete mixers being "charged" by men with wheelbarrows.
