If
you're not an engineer some of the calculations may escape you,
but don't worry, the video explains all the calculations in one go
!!
Something
to cheer up the Engineer in you.
Just
to put you in the picture and keep you up to date with the
latest developments.
Below
is a link to a short video of a Pakistani pile driving
construction technique!
The
chant is also catchy!
Now,
let's analyse the Engineering here:
6
men x 180 lbs = 1080 lbs static force.
Jumping
up and down will create a 3 times dynamic effect = 3240 lbs/jump
= 1.6 ton thumps if the pile is tapered to 2 in x 2 in, cross
section at the tip = 4 sq. in. So, dynamic pressure/thump at
pile tip = 3240/4 = 800 psi.
"Add
a man" feature will increase to 950 psi, so buy the
option!
Increase
the chant and dynamic force goes up to 5 times to bring
max.
pressure / thump
to 1600 psi for a 7 man team.
Quite
good, and will penetrate hard clay and sandy soil (but not hard
or rocky ground!) Pretty ingenious.
Oh, the
foreman is the guy on the tambourine.
