7 5/8" pipe for pile core
In
an apartment complex at an ocean front site in Westhampton, NY, Underpinning
& Foundation of Maspeth NY, installed TPT Piles with a slight twist.
The piles were to extend one story out of the ground to become columns
to support the structure. This made accurate placement of the piles essential.
Typically
TPT Piles use a large tapered concrete base that is fitted with a corrugated
shell, and is mandrel driven into the soil. In this case a 14 inch steel
pipe was used instead of the shell.
Another unusual item was that a
7 5/8" x .375 wall pipe core was inserted in the upper portion of the pile
to increase the bending strength of the piles. The piles extended to the
top of the first floor so accuracy was critical.
