Hi


I need to temporarily shore up a wall, about 8' high, with vertical
scaffold poles concreted into holes, and linked horizontally to the
wall. The one q I dont yet have a clear answer on is how far they need
to be sunk into the ground. Also I'm not familiar with what the best
tool would be to dig with.

Thanks, NT

Sounds a bit dodgy to me! - since it applies bending loads to the vertical
supports which they may be unable to resist.

Surely [or shorely g] a more usual way would be to have vertical supports
against the wall, horizontal supports at ground level - with pegs in the
ground at the remote end, and sloping supports anchored to the top of the
verticals and to the remote end of the horizontals in order to triangulate
the whole thing.

Is there some reason why you can't do this?

If you dont know what or how to do it DONT!
Contact a structural engineer and he will design the supports for you
As for digging holes if you can use a mini digger then use it if not the
good old fork shovel and pick comes to mind

Shoring needs to be in a cantilever form to be of any use. The frame for
your supporting section should be robust enough not to bend when any weight
is applied to the side against the thing you're supporting. Scaffold tubing
would need to be built in the form of a web with interleaved and tied
members across it to reduce or spread the bending pressures across the whole
framework.

Anything in or on the ground which stops the frame from sliding away needs
to be able to take the weight of the frame and the wall, so pouring concrete
blocks which contain anchor points for the frame need to be worked out
carefully.

If it's a free standing wall, then why not demolish and rebuild it with
proper buttresses and foundations ? If it's a wall for the house, then
you'll need it all calculated positively if you're going to live with it.
