Background<\/h2>\n\n\n\n

The Union Pacific Railroad operates in North America, covering 23 states in the western two-thirds of the United States. The railroad is responsible for 32,100 route miles, with 6,336 of those miles running through Texas. Located under some of these miles of rail, are storm water drainage culverts that were installed 40 to 50 years ago and are now past their design life span. <\/p>\n\n\n\n

The Union Pacific Railroad regularly maintains all of its railways and rail structures. As part of this regular maintenance, Union Pacific located a severely corroded 84-inch ID corrugated metal culvert (CMP) that it needed to reline. The location of the culvert was under a stretch of rail in Athens, Texas. <\/p>\n\n\n\n

The railroad looked for a solution that would not disrupt any rail service during the rehabbing of the culvert. With its commitment to safety, the Union Pacific also required a safe method of fixing the culvert that its own maintenance crew could install. <\/p>\n\n\n\n

Snap-Tite\u00ae Culvert Rehabilitation Solution<\/h2>\n\n\n\n

Culvert rehabilitation extends the life of aging drainage infrastructure (corrugated metal, concrete, brick) using trenchless, no-dig methods while avoiding costly and disruptive excavation.<\/p>\n\n\n\n

J. David Bateman from Union Pacific\u2019s bridge department worked with Snap-Tite Representative Trevor Cone to find a solution for the deteriorating CMP. The pipe chosen to line the corroded culvert was a 63-inch OD high-density polyethylene (HDPE) Snap-Tite pipe<\/a>. The railroad chose to use Snap-Tite because the Snap-Tite system does not require any special training or special equipment, so the railroad\u2019s maintenance crew could handle relining the failing culvert. In addition, the Snap-Tite culvert lining system is a no-dig solution for culvert repair, meaning there is no need for major excavations or disruptions to the rail or road traffic during construction. <\/p>\n\n\n\n

\u201cSnap-Tite gave us the solution we needed to safely restore the culvert and not interrupt service. This was vital to us,\u201d said Bateman. \u201cIt was also vital that the product and installation method we chose be both cost-effective and provide us with a permanent solution. Snap- Tite provided us with both.\u201d <\/p>\n\n\n\n

Cone along with Snap-Tite Director David Hundley were onsite to assist the Union Pacific crew with the Snap-Tite installation. Snap-Tite\u2019s quality control program ensured that the Snap-Tite pipe joined in the field provided a water-tight storm water system. Snap-Tite has patented male\/female machining at each end of the HDPE pipe, which allows the pipe to be \u2018snapped\u2019 together. <\/p>\n\n\n\n

The grouting of the annular space filled any voids created by the corroded CMP. The newly installed 63-inch OD Snap-Tite pipe culvert liner offers a 102 percent improved flow rate compared to the existing 84-inch ID CMP, so the smaller diameter pipe actually increases flow. Now lined, the old culvert is at full strength and expected to have an indefinite service life. <\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"

Dive into the endeavor undertaken by the Union Pacific Railroad, spanning 23 states in North America, to rejuvenate its rail infrastructure while maintaining uninterrupted rail operations. Amidst regular maintenance, the railroad encountered a corroded 84-inch ID corrugated metal culvert beneath tracks in Athens, Texas. The ingenious solution came in the form of Snap-Tite’s 63-inch OD high-density polyethylene (HDPE) pipe, chosen for its no-dig installation, operational safety, and remarkable flow rate enhancement. This strategic collaboration between Union Pacific and ISCO’s Snap-Tite product showcases a pioneering approach to rail culvert rehabilitation, embodying efficiency, sustainability, and lasting infrastructure resilience.
