Pakistani Pile Driving.... NON-UNION

[Teehaml]

Here's a construction technique that would be handy to know. Read the calculations below then click on the link at the bottom of the article to see this technique in action. It’s something to cheer up any engineer. It will put you in the picture and keep you up-to-date with the latest construction developments.

Now, let's analyze 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 = sq. in. So, dynamic press "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 maximum pressure/thump to 1600 psi for a 7-man team.
Quite good, and it will penetrate hard clay and sandy soil but not hard rock!

Below is a link to a short video of a Pakistani pile driving construction technique. Notice that the pile driving becomes effective when the extra man jumps on. Very finely tuned! The chant is also catchy. The foreman is probably the guy with the tambourine...

Nifty.

It's fantastic. Bet if we had a YouTube of the guys building the Pyramids or Stonehenge we'd see something equally clever and effective--that's been totally forgotten. Stationed in Turkey, I saw some pretty primitive building techniques, too, like wooden planks laid out in a grid over a concrete foundation being poured, with an endless line of guys carrying and dumping individual buckets of wet cement where needed, instead of a big boom coming off a giant cement mixer like we're used to. Never saw this one, though. Thanks.

Was in Mexico City for a week in 1976, saw a three story hotel being poured out across the street just like this: One bucket at a time, muy Peligro!

So...that's real neat when you go through the loose sands...but how about when you get down to the bedrock or hardpan bearing level. I doubt if 5 guys jumping up and down on a board is gonna get it to adequate refusal.

I presume the piles are gonna support a building that weighs more than five happy guys gyrating on it.

It's a whole different ball game without building codes.

Or the OSHA requirements.
