I am creating a model that consits of 1 basic material but that has different bump-maps on its surface.
How can i layout my nodes to assign different bump maps to one material?

It depends on how many different bumps are we talking about. If you have 2 or 3, then you can mix the textures in Octane with a mix node, but you'll need a mix texture for each mix node (so 2 mix textures if you have 3 different bumps). If you have more than 3 different bumps, than you'll be better off creating a specialized bump texture for your model in Photoshop or GIMP.

being a bump map a b&w image you could try with a multiply node also, just hooking both of them to the multiplier and then hooking it to the bump channel
