India Pile Driver This is how its done without tons of money for heavy equipment. A short video of a Indian pile driving construction technique. Notice the pile driving only becomes effective when the extra man jumps on. Very finely tuned! The chant is also catchy! Now, lets 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 = 4 in 2. 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 rock! Pretty ingenious!! Click on this for video: New South-Asian construction process https://youtube-nocookie/embed/cFb0nLCKypg?rel=0 (The foreman is the guy on the tambourine.)
