Yeah, I'm back to the tunnel again

I was thinking of the over the garden gate type:

And maybe it's big enough as it is :confused: The thought I had was if a person could get a T connection for the pipe. At the highest part of the loop, cut the pipe and put on the T. Put a short piece of pipe coming down out of the T towards the ground. I imagine there's some type of "cement" that can be got to properly stick the joint.

The idea being, could a larger wider loop be supported by having scaffold poles in the middle of the tunnel also? Those scaffold pipes could also be tied together along the length of the tunnel quite easily as they'd be away from the cover.

Thoughts? Faults? Madness?

sometimes it may work out cheaper to buy a proper one ever thought of that.

I think it would be sturdier with a one piece of pipe rather than two sections joined. But if you are making it very wide, then put uprights beneath the hoops (something like sturdy 4 x 4 timber. Don't forget it does snow here It can add a great weight and you would need vertical support to the ground. Just rest it square on a level slab. That's just my thinking on it.

you can get tunnels made to any size or shape single span or multi span with plastic to match the gales and depths of snow. They are far superior to any home made tunnel.
