January 14, 2007: No more Pearman piers - T-2 implosion
Riding across the Ravenel Bridge with Sparky at 3:02 pm
The worksite: Grace pier to the left (where Michael will punch a hole and remove
the inner shell), Manny's crane with Manny in the driver's seat,
T-2 behind him and the Ravenel Bridge in the background.
Stacked containers as a blast barrier on the left
Ken and Randy up for a last check of the setup

Here is the frame
by frame sequence of ignition and detonation
T = 0 msec T = 33 msec
T = 66 msec T = 100 msec
T = 133 msec
Note the shock tube track from the columns to the cross member
T = 166 msec
T = 200 msec
T = 233 msec
T = 266 msec T = 300 msec
T = 333 msec T = 366 msec
T = 400 msec
T = 433 msec
T = 533 msec
Note shock tube ignition at the cap and detonation at the base of the left column
T = 566 msec
T = 466 msec T = 500 msec
T = 600 msec T = 633 msec
T = 666 msec T = 700 msec
T = 733 msec T = 766 msec
T = 800 msec T = 833 msec
T = 866 msec T = 900 msec
T = 933 msec T = 966 msec
T = 1000 msec T = 1033 msec
T = 1066 msec T = 1100 msec
T = 1133 msec T = 1166 msec
T = 1200 msec T = 1233 msec
Shock tube ignition (see right column about 1/3 up from the base)
Initial blast: note the lateral dispersion of debris on both the
left and right columns
And compare with
Friday's T-1 blast where the right column was wrapped with chain link
fence
and the left column was unwrapped
and then collapse of T-2
with smoke
but not much else
After
After close
From the dock - no T-2, only blast barriers. Next job, Mickey and Ken
will bring out the Copco and start drilling vertical blast holes
to remove the base and sub-structures.
Going home for dinner with Sparky
