Benefits of technology
This solution allows for cost-effective, rapid, and minimally disruptive repair of damaged culverts, reducing downtime and traffic disruption while maintaining structural integrity, enabling continued use of driveways, sidewalks, and roadways.
Problems solved by technology
However, these culverts and pipes do not last forever, and can crumble and collapse after many years of use.
Since the culverts are considered to be permanent solid structure, cracks are only repaired with temporary patches and are not done for long lasting effects.
After years of use and damage, the culverts usually need to be replaced when they're life as run out.
Currently, it is a very costly endeavor to have to physically dig up the driveways, sidewalks, roadways etc. in order to install new culverts when the old ones are needed to be replaced.
Additionally, replacing a culvert can take up to a couple of days or more time which can result in the driveways, sidewalks, and roadways around the culverts not able to be used.
Culvert repairs can require multiple permits and large amounts of labor and material costs.
In addition, businesses and travelers have to detour about the areas where the culverts are being replaced causing further delays and hardships.

Devices, apparatus, systems and methods for forming rolled up spiral shaped tubular inserts of interlocking seams of elongated strip material and for inserting the inserts into damaged channels such as culverts, sewer lines, pipes, and the like. The inserts are released to expand outward and unravel until the walls of the unraveling insert abut against interior walls of the damaged channel forming a protective interior wall for the damaged channel. One side of the insert strips can have a hook, and an opposite side of the strips can have a longitudinal groove wherein the hook attaches to and slides within the groove. Slidable surfaces such as bushings, Teflon coatings and O-rings can be used along the interlocking seams to allow for reduced friction as the strip materials are rolled into contracted positions and later expanded out.
Description
[0001]This invention is a Divisional Application of U.S. patent application Ser. No. 13 / 117,566 filed May 27, 2011, now U.S. Pat. No. 8,496,048, which claims the benefit of priority to U.S. Provisional Application Ser. No. 61 / 351,632 filed Jun. 4, 2010. The entire disclosure of each of the applications listed in this paragraph are incorporated herein by specific reference thereto.FIELD OF INVENTION[0002]This invention relates to culverts, in particular to apparatus, devices, systems and methods of making spiral cut pipe materials into expandable inserts for damaged channels such as culverts, drainage canals, sewer lines, pipes, and the like, and installing a spiral cut pipe liner insert into the channels, and expanding the insert to become an pipe liner for the damaged channel that can be used under driveways, sidewalks and roadways, and the like.BACKGROUND AND PRIOR ART[0003]Culverts are permanent structures that are generally installed underneath driveways, sidewalks, and roadways...
