Pipe on pylons over creek
Pipe on pylons over creek
(OP)
We have a Ductile Iron Pipe carrying domestic sewage supported by pylons over some creeks anbd ravines. We will be lining this pipe with CIPP. What kind of analysis would I be doing to make sure that the pipe does not snap between supports. This is a gravity line, so each support will be lower than the last as you go downstream.

You have to determine the pipe material, wall thickness, evaluate type of saddles, and determine pipe lengths. The dipra paper outlines the design procedure.

Make some preliminary calculations according to the dipra paper. If you are close to the breaking point, you probably will have to get an professional opinion on the composite lining/ductile interaction.

Depending on the size of the project you could directionally drill under the creeks using PE. This avoids the issue of contaminating a water course if the worst happens during flooding.
Aerial crossings using plons and cables have been used to cross ravines.
As there is no detail on size of pipe and crossings it is difficult to help.
