Thanks everyone for your responses.
To clarify, the rising main in question is 160mm diameter HDPE and will be carrying foul sewage. Site constraints mean large radii (20, 30, 40m etc.) are out of the question, therefore leading me to think thrust blocks are definitely needed. In which case I...
Hi,
I'm completely new to eng-tips as well as completely new to designing rising mains so I'm on here looking for advice.
If bends in my rising main are, what I consider, a fairly large radius (in this case 4m) do I still need to include thrust blocks? If so is there a rule of thumb radius at...
