摘要 |
A method of continuously impregnating a resin impregnable cured in place liner in a resin impregnation tower is provided. A cured in place liner having at least one layer of resin impregnable material is fed into the top of the tower, drawn down about a roller at the bottom, removed from the top of the tower and then wrapped with an outer impermeable coating. The tower is filled with resin at a suitable height to provide a sufficient pressure head of resin to impregnate the resin impregnable material fully. The impregnated liner is suitable for inversion or the pull-in-and-inflate method of installation. For liners formed with an inner impermeable layer, the liner is suitable for curing with steam. |
