Plastic Pipe Manual - Prime Conduit

Once the pipe is grouted, the long term buckling resistance should be checked. Like all flexible pipes, deflection calculations should be performed for pipe installed by sliplining. A veryconservative approach is to not consider the existing pipe in the calculations.
