Unified Design Method for Most No-Dig Rehabilitation Liners
Publication: Journal of Transportation Engineering
Volume 131, Issue 9
Abstract
The liner materials used for pipe renovation are usually designed to meet some minimum consensus standards. Often, the design guidance is listed in the Appendix of the standards. For additional guidance, numerous design manuals, not part of the pipe standards, are distributed by each vendor or technology holder uniquely geared to their own technology. There is clearly a lack of standardized design methods that allow direct comparisons between available materials or provide final designs on an equal performance basis. This paper will provide a unified design approach so that most no-dig pipe rehab liners are designed by the same set of engineering guidance. Engineering issues, pertaining to various loadings imposed on the liner, buckling behavior of the liner allowing for ovality, size of the annulus, wrinkles, annulus grouting, stresses, and strains in the reliner pipe wall, are addressed. This paper would be of interest to technology holders, owners of pipeline networks, pipeline asset managers, consulting engineers, and regulators.
