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.
Below is a link to a short video of a pile driving construction technique. Notice that the pile driving becomes really effective when the extra man jumps on. Very finely tuned!
The chant is also catchy. 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., the cross section at the tip = 4 sq. in. That equals 1.6-ton thumps applied to 4 sq. in.
The "Add a man" feature will increase the dynamic pressure 950 psi, so buy the option! Increase the chant and dynamic force goes up as much as 5 times to bring maximum pressure/thump to 1600 psi for a 7-man team.
