constructing columns in water
constructing columns in water
(OP)
Does anyone have any resources on construction in water. (lake or pond.) I am working on a project that the Civil wants to use auger cast piles. I've always used driven timber piles. This part of the project is a fishing pier in a state park.
Any suggestions on construction material, suggestion method for the Contractor, and/or shoreline disturbance requirements?
Thanks.

I would say, use a driven pile also. Though I am curious about the connectin detail.

Only problem here I see is whether the local Building Department/Corps of Engineers/EPA will allow you to place piling at that location (eelgrass, etc.). Might turn out to be an environmental problem, not an engineering one.

My question to you, after cut off of the pile at mudline, how will it be possible to strip the steel pipe pile without breaking the concrete inside?

I think the idea is okay for just one pile, but extremely costly for a project that will require more than one pile. Also, the heat during torching may affect the quality of the concrete.

Seriously though, I would not be worried about heating up the concrete too much with all the water in the vicinity. How many pile are involved, and how far do they project above the mudline on average?

I doubt the cutting off the steel pipe is a very good idea. I also doubt there is any such thing as an underwater torch - I think the only option is arc-air gouging.
Why not leave the pipe in place, if you really have to remove then you should make it up into a bolt together formwork in the first place.
I would go for driven timber, steel or concrete piles. If the auger is a must then a steel casing (or formwork as mentioned above)could be pushed in and then auger through the void.
During concrete I would expect bentonite to be used, if not I can only imagine what sort of condition the concrete will be in.

Headline today on the internet - I rest my case.
