I'm jealous. Lattice boom crane. One man on the sheet with a level, one on the vibro unit, and a good crane operator. Make it happen.

A very good sheet pile driving technique in Java

To the commentator, let the foreman and the crew do the job. I'm sure he knows what he's doing!

@Mel McGrath Dinosaur equipment? It’s an excavator with a vibratory hammer. Not exactly the preferred equipment for driving 40 foot sheething. .

The pitch, and drive method eliminates the need of pitching sheets with a man lift at a higher elevation. However this method as seen in the video can be fraught with issues in sheet alignment as pointed out. If this method is used extra attention needs to be used in getting sheets plumb in both axis. I prefer using double leg rigging when sewing the double sheet piles. It doesn’t eliminate the sheets separating as in the end of the video. However it does allow the stray single sheet to be pulled back up. With The single leg basket used. Once that happens you are screwed. If this is temporary sheet piles to be pulled later after excavation is completed. Depending on the length of the wall, I rarely use a template beam, say in stage line sheeting for bridges etc.. Unless alignment is critical.

What I would do is lace the new sheets into the short driven sheets then pull up the short driven sheet up and drive the new laced sheet down. Lace the next sheets and pull up the driven sheets. keep the sheets fairly high and work on making them plumb and then drive them to grade.

I want to add some information on why vibration easily drives these sheet piles. When you vibrate these things, the soil beneath it experiences a sudden change of loads in which the soil may lose virtually all of its strength and behave as a liquid. This phenomenon is called soil liquefaction. ^_^

Good job , but I prefer Crawling lattice boom crane .good luck stay safe .

Re-design the sheets to have wider male and female slots, I am thinking of a sea wall for Lake Superior.

What is the driving sheet pile equipment?

I've seen the concrete version of these piling sheets. They are susceptible to damage from the driving hammer.

ITS Very nice work i need amore vedios

use a level it works , makes the job easer to plumb up the sheets that machine can plumb up the sheets fairly easy you should be able to drive 35 to 40 pair of sheets a day if you lay out everything and they can supply you fast enough

Is this machine in ABI or a RG

The steel looses it elasticity once in all the way

What is the ground condition here? Is it dominated by clay or clayey like soils?

If they're using a vibratory hammer like this it's Sandy soil. It can extract sheets from heavy clay but not to drive piles

Every crew is different and different jobs require different methods. The only thing I would have done different is leave the sheets up fifteen feet higher then come back and drive them to grade. The operator needs to get directly over the interlock and the sheets will slide down, regardless how far out of plumb it is.

why dont they tack weld the two sheets together before driving in

good builder

Very good 👍

Good work

They obviously forgot to weld those sheets together, could have been nasty..

Nice

When carpenters try to be Piledutts.

Hahah. Yup. That’s coming from carpenter.

My mistake it looks like a RG16 or a RG21

grease on the edge of the sheets might help

My personal opinion is they shouldn’t try and lace the sheet while it’s hanging, should stab it in jaws so they can tweek as needed to lace .... it’ll probably take the equal amount of time

Im sure it wasn’t. One of my friends did 32 crazy ….. Ive made some very poor choices myself… i just got lucky….

Is

What a waste of expensive machinery. A couple of million for that machine and they still can't get a sheet in plumb. They need a new crew!
