Hi - I'm checking opinions. I'm designing a C900 PVC pipeline (12") for potable water distribution that is going across open ground in a straight line, and then crossing a highway in a bore that will have a jacked steel casing. The pipe within the casing will be mounted on centering skids. My questions are: (1) Do I need restrained joints within the casing (pipe outside the casing has enought straight laying to not need restraint). (2) Is PVC the appropriate material within the steel casing? (3a) Do I need to fill the annular space within the casing? (3b) With grout? (3c) Blown sand?
