Building a jetty with scaffolding materials

[Albin95an]

Hello!

Looking for some thoughts and ideas for the dock construction for the summer.
The idea is to keep the budget low since we only rent the berth but maintain it ourselves.

The base will be a construction using scaffolding material as it feels stable and I can get it at a reasonable price.
The platform frame will be 2 x 7m telegraph poles, with beams to attach decking to, and then the decking itself.

My question regarding the construction is what would be the most stable way to build the scaffolding.

I have made a very amateurish sketch which you can see here.
Either to secure the whole scaffolding as a box or just an H-formation to prevent the uprights from bending outward from the dock.

Is a 1m width for the dock enough or will it be too unstable? I’m thinking the platform should be elevated a bit to handle the water level differences.

Hoping to brainstorm a good dock under these conditions, thanks in advance!

I have nothing to say about the construction. But can you build a jetty considering the shore protection? Or is there already an exemption or has it been revoked in another way?

Forgot to mention this, there's already a bridge in place today but it has had its day, and it's not worthwhile to try to straighten it up again this year.

1 meter is enough but 1.2 meters is probably a standard measurement. How are the bottom conditions and what are your plans for the poles?

I interpret it as permanent?
Then you want it to withstand storms and possible ice, and spontaneously I think your solution looks weak for that.

We build a bathing jetty every year with burtonrör, but we take it in every fall, otherwise the autumn storms will do it for us.

The bottom is muddy with some sand mixture, the current dock is oak posts driven into the mud, thinking the same for the frame but with longer pipes since I guess the narrower pipes will be easier to drive/hammer down the longer they are.

We build a swimming platform every year with Burton pipes, but we take it in every autumn; otherwise, the autumn storms will do it for us.

The idea is that we should be able to pull up the platform itself in the autumn and only leave the post, unless the post is loose enough to pull up again.

We have our poles shod with a metal rim that we place on the bottom, but then we have sand and stone that move with the waves. The pier has both shifted position and settled significantly when we pick it up in the fall, but then it is also lying in the sea.

Burton pipes pushed down into mud will slowly but surely continue downward until they find solid ground and cannot withstand tougher ice conditions. In a calm small lake, it works, and in a well-protected bay where neither wind nor current can pressure the ice, it may work. The biggest problem is that it can be a hell of a task to pull up something pressed into mud, so the idea of removing them in winter probably won't work. What you can do with burton pipes is to have joint sleeves a bit down where it is ice-free in winter, then you can disconnect the part of the pipe that sticks out of the water.

Don't forget to submit a notification about water activities to the county administrative board. It's needed even if there is a dock at the location today.

I would sharpen and drive down a couple of telephone poles, then you can bolt a couple of thick planks between them.

Scaffolding material is a shame to use for a dock, you will surely need the pipes when you need to reach the gable peak of the house.

Now you might have sparked something new. Couldn't one do something similar with an old rim, an anchor, or the like in our mud so that it might not sink as deeply? It might be practically impossible to get it up once it's set in the clay, but it should stand more firmly and perhaps be easier to straighten up in the spring?
