Thanks for reply. Some of you are looking at me building something way over engineered. I am driving a 2600# tractor over a small stream. Current set up worked until it was partially cut/squashed near an end. And it still functions as long as I stay up on keeping it clear, which I forget, since I rarely use, and then damage is done. Money IS an object here.ok thinking out of the wrong end here but but wondering
could you dig a ditch
put something like rebar chairs down
put the barrels in
pour a few inches of concrete
pour a few more inches of concrete, hopefully with something to keep the barrels down
keep pouring a bit more concrete, perhaps some rebar here and there
and end up with a cheap-ish concrete culvert by using the sides of the ditch and the barrel as a form?
probably way too much work and needs enough rebar that you'd be better off buying a corrugated culvert...
