The construction near the Forest intersection in Kenai is using a slip lining, not directional boring as we previously reported.
Jill Reese with the State of Alaska said a storm drain outfall pipe failed which crews are using a new technology to repair.
Reese: “Its an interesting technology they are using, its a new technology that’s only been out for a few years and what they do is its called a slip line and they put a great big balloon into the pipe and then they put an ultraviolet light in and the ultraviolet light activates the balloon and turns from flexible into hard and then it has the same strength as the original culvert.”
She said that method is cheaper and has less of an impact on the roadway.
Reese also said the road boring project to replace culverts is in the designing and planning phase for 2015.
Reese: “The bores for fish passage is like a 2 million dollar project, we had two culverts there that failed they just went to the end of their life, it wasn’t unexpected, and so since these culverts are 25-30 feet below the road it would be quite the operation to dig those puppies up and so they were able to secure some capital funding that was named trenchless funding to replace culverts like this.”
