Hi this not how we install sheet piles in New Zealand. We don’t use those frames for the sheet piles. We lay a sheet pile along the ground and then use tie backs to hold into position,then drive the sheet piles in using the sheet pile as a frame. This way we can long stretches (100 meters and more) without using expensive framing blocks. I’m always interested to see other techniques with sheet piling thanks for upload.
I watched the construction of a bridge near me when I was a kid, back in the 1970's how they did the sheet piling was to drive in a series of H beams in line set back from the line a bit, they then welded a cross beam and had it all in line. Two cross beams were installed. the sheet piling was stacked up against it. They loaded a bunch of them then hammered them in with an air hammer on a crane. When they were finished with that "run" they removed the H beams and Cross Beams and applied U Channel with the "U" facing down and welded it. Looked pretty neat to me!
@@garyphillips2315 yep, i just finished a job on friday...and thats still how its done, we set up a jig using piles which will be the internal wailer's in the end...one in front of the face of pile line, one behind...then drop the sheet piles in between, level them then tack some quick welds to hole them in place..cut them loose with a grinder or cutting torch once you grab them with the vibro...makes for a nice level/straight wall when complete
how do you combat sheet piles that are hard to drive in because of rust? new piles are not an option due to the time and type of job we're on. any ideas much appreciated.
