Hi Guys
We are about to restart shaft sinking at Bonsall Moor Swallet upper sink and I'm trying to decide on the best king of support for behind our scaffolding cage. We were hoping to get a machine on site and put a pipe in before backfilling but the land owner isn't up for that so it looks like we are back doing things the hard w.ay I'd really like some feedback from other peoples experience. My initial thoughts are:
.
Scaffolding boards - Easy to use and strong but they don't seem to last very long especially near the surface. On the plus size they can often be got very cheaply if you know a site that is being cleared.
Tanalised Board - Easy to use and lasts longer than scaffolding boards but can be of variable quality. Good quality board seems expensive.
Half round fence posts - Easy to use and seem stronger than sawn board. The pointy end is easy to drive down. Can be expensive for good quality posts.
Corrugated Steel - Stuff from the 40's and 50's seemed good but almost impossible to get hold of now. New stuff seems so thin that it won't hold any weight.
Used Domestic radiators - I have no experience of these but they seem quite strong and will probably last longer than timber. Probably more difficult to use than other options but a 9" grinder will sort most things. Steel scrap prices are currently low.
Any thoughts very welcome.
Thanks
Julie
