I am looking at installing some anchor points that my scouts troop could use.
We intend using them to tie off heavy rope that will form part of a rope type bridge that the scouts will build.
the idea is that you have two 'A' frames one at each end, the rope then goes over each A frame and ties off to an anchor point.
What i need to gauge is what size would the anchor point need to be - there would only be person on the rope at a time but i would want to estimate say
3 persons so that its well anchored.The anchor points will be buried in a field so im thinking of say a metre cubed of concrete and then some rebar loops buried in them to tie off the ropes and have them about 75mm below ground level to to avoide the lawn mower catching them.
is a metre cubed way too much, would prefer to use less concrete and dig less soil out :-))
looking for some advice please - thanks d
