You can simply take the pipes and cross them like you are making a dome tent. Just lash them together at the center of the top X and slide the bottom ends onto some rebar driven into the ground to act as anchors or slip them into cinder block holes like that one anon does on here. Cover it in plastic and you have a super sturdy PVC greenhouse. Add multiples together and you can have a super sturdy polytunnel.
It will be sturdier than the ones you get from Hazard Fraught. If you do get one from Hazard Fraught, make sure to get a few 2x4s to make cross bracing to make it sturdier in wind.
